In response to emerging IP-based data and voice services, ARRIS brings to market a next-generation, carrier-class Cable Data Network Solution — the C4® Cable Modem Termination System (CMTS). ARRIS has deployed more than 4600 CMTSs supporting millions of subscribers. The CMTS has been designed to meet the needs of the Multiple System Operator (MSO) in terms of system density, wire-speed performance, and reliability. The CMTS enables MSOs to bundle high-speed data, voice, fullmotion video, and other multimedia content to residential and business customers.

Intended Audience This document is intended for MSO technical support personnel who are responsible for integrating, operating, and maintaining the CMTS.

The Command Line Interface (CLI) is the software tool used to provide users with administrative control of the CMTS after hardware installation is complete — whether from the console or through a remote network connection. The CLI is a straightforward command interface in which commands are typed on a single line and executed by pressing the Enter key. The CLI provides command help, command completion, and keyboard sequences that enable a user to navigate a command line and scroll through a buffer that contains recently entered commands. The CLI enables system operators to enter the commands needed to add, manage, display, and remove hardware modules, networks, users, and other system entities.

2 CLI Overview

C4/C4c CMTS Rel. 8.0.7

Access Levels and Modes The CMTS CLI supports two main access levels: User EXEC and Privileged EXEC. User EXEC

Users first logging in to the CMTS are assigned non-privileged status. The command line prompt will be the machine name followed by a greaterthan sign (>). There are two levels of User EXEC, signified by a 0 (zero) or 1 (one). The 0 commands are associated with logging in, changing privilege levels, and logging out as shown in the following list: disable enable no enable [] end

exit [all] logout quit [all]

The level 1 commands are only a subset of the CLI commands, the ones that display non-privileged information. You are not able to enter commands to change configuration or display privileged information until you become a privileged user. Privileged EXEC

To become a privileged user, enter the enable command. Normally, you must enter a password to enter Privileged EXEC mode. You are permitted three unsuccessful attempts to enter a password before the connection attempt is refused. If the password is accepted, the end of the prompt changes to a pound sign (#). From Privileged EXEC mode, you may access global configuration mode. In this mode, you can enter commands that configure general system characteristics. You can also use global configuration mode to enter specific configuration modes. (See Table 2-1).

CLI Command Modes The CMTS supports hundreds of CLI commands. They are grouped into different functional modes. The first set of commands is available to all users including those with non-privileged access. Most of these commands are used to show system status. They are available when the CMTS is in User EXEC mode or any other mode. The other modes are available only to users with privileged access. These commands are more powerful and can be used to reconfigure the system or to adjust system performance. This command reference manual lists the CLI commands in straight alphabetical order.

CLI Syntax Conventions ARRIS documentation uses certain conventions to show the syntax of commands. These notations are not part of the command itself but indicate command entry options. The notations are for documentation purposes only, they are not input by the user. The CLI commands in this chapter use the syntax conventions described in the following table:

Table 2-2: Conventions for Representing Command Syntax CLI Syntax

Description



Angle brackets indicate a required value or parameter which is position-dependent and does not have keywords.

[...]

Brackets enclose optional entries—they may be included or excluded.

{...}

Braces enclose two or more entry choices; one and only one choice should be entered in the command.

[...]+

“+” Represents multiple, so the inside of the brackets must be 0 or more times.

{...}+

“+” Represents multiple, so the inside of the braces must be 11 or more times.

{...}+2-12

“2-12” represents the number of times it repeats. In this case, 2 through 12 are legal repetitions.



Parameters preceded by an asterisk indicate a wildcard. They may use an “*”, a range (2-5), or a list (1,2,5,7,9).

[word {a | b}]

|

Braces and a vertical line within brackets indicate a required choice within an optional entry. A vertical bar (the “pipe” symbol) separates entries within brackets or braces. You may select only one from the key list: [first | second | third]



Issue 2.0

Values are required for both the slot and port. They must be separated by a slash. Parameters preceded by an asterisk indicate a wildcard.

Table 2-2: Conventions for Representing Command Syntax CLI Syntax

Description

Wherever an IP address is required, you can enter a IP addresses and host name provided you have configured a DNS server host names or put the name and address into the DNS Local Host Table. Script files

You can create a script file—a text file containing CLI commands—to simplify repetitive tasks.

Designating MAC addresses and IP addresses Some commands require a Media Access Control (MAC) address or Internet Protocol (IP) address, which must be entered in standard form. The CLI displays MAC addresses in the following formats: 1111.2222.3333

a0b1c2d3e4f5

a0b1.c2d3.e4f5

a0:b1:c2:d3:e4:f5

IPv6 addresses use the standard conventions: Hex digits are case insensitive, leading zeros are optional, a pair of colons indicate successive 0’s have been dropped and only one pair of colons can be used. The following represents the same IPv6 address: 4012:0000:240E:0000:0000:0AC0:3428:121C 4021:0:240E::AC0:3428:121C 4021:0:240e::ac0:3428:121c

Keyboard Shortcuts In the CLI, you can use keyboard sequences to navigate and edit a command line. You can also use keyboard sequences to scroll through a list of recently executed commands. The following table lists the lineediting keys that are available in the CLI.

CLI Command Features CLI features several built-in enhancements that make it easier to use. These include help, abbreviations, alias commands, filtering, and general features.

CLI Help Feature Command completion and positional help are two features that serve as memory joggers for users who are unable to remember the entire command string or parameter placement. Use of Question Mark (?)

Entering the question mark (?) at the command line prompt will display a list of the available commands. To get specific help on a command mode, command name, keyword, or an argument, use any of the following commands: Table 2-4: Command Help Command

Entering the question mark (?) in the middle of a command name, enables the CLI to list the possible command completions that match the letters you have entered so far; the letters that you typed are redisplayed. When you find the value you need, type it without losing your place in the argument. Leave a space between the keyword and the question mark. The question mark will not invalidate the command. When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant. To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. Interactive Mode help

The use of help and the ? mark in interactive mode are not the same. To list the options available for a specific command, type help at the prompt. To see all the enhanced options, enter a space, question mark (?) followed by the enter key. The behavior differences are shown in the two examples below:

Use of the Carriage Return

The (carriage return symbol) at the end of a command help output indicates that you have the option to press Enter to complete the command and that the arguments and keywords in the list preceding the symbol are optional. If there is a mandatory parameter that needs to be entered, no will appear.

Error Indicator

The CLI provides error isolation in the form of an error indicator, a caret symbol (^). The ^ symbol appears at the point in the command string where the user has entered incorrect or unrecognized command syntax. For example, the ^ symbol in the following output shows the point at which the error occurred in the command (e.g. clock is misspelled): C4# configure clokc ^ Error: Invalid parameter

Command Completion

Command completion for command names and options is available at each level of the hierarchy. There are several options you can use to complete commands. You can abbreviate commands or keywords: enter only as many characters of the keyword as needed to keep it unambiguous. For example, you can abbreviate the configure command to config. After entering the command at the system prompt, press to execute the command. If you enter a unique set of characters and press the key or , the system will complete the command name. If you enter a set of characters that could indicate more than one command, the system will respond with the list of possible matches as shown in the following example: C4# configure cable mod modem modulation-profile

Command completion will then work if you type either an “e” for “modem” or “u” for “modulation-profile” and press the key or . The system will complete the command name. After the command is complete at the system prompt, press to execute the command.

Configuring Passwords and Privileges A simple way of providing terminal access control in your network is by using passwords and assigning privilege levels. By default, the CMTS CLI has two levels of access to commands: User EXEC mode (level 1) and Privileged EXEC Mode (level 15). However, you can configure additional levels of access to commands, called privilege levels, to meet the needs of your users while protecting the system from unauthorized access. Up to 15 privilege levels can be configured, from level 1 to 15. Users who log on with level 15 have access to all commands. Users with privilege level 1 have access only to most show commands. The configure enable command defaults to privilege 15. If a given command is set to privilege level 7, for example, then all users having privilege levels 1 through 7 must supply the correct level 7 password before the CMTS will accept the command. By configuring the privilege level, you can limit access to each privilege level by enabling separate passwords. For example, you may want a certain set of users to be able to configure only certain interfaces, but not allow them access to other configuration options. You would create a separate privilege level for those specific interface configuration commands and distribute the password for that level to those users. Or, if you had a group of trainees, you could assign passwords to certain privilege levels, and give them these passwords only when they had completed their training. To create a new privilege level, password, and associate commands with that privilege level, use the following example beginning in global configuration mode: 1 Enter enable mode: C4# enable 2 Create the password and set the privilege level required to use the password in order to access privileged commands: C4# configure enable password privilege

Where password is a string up to 16 characters long and privilege is a number 1-15. If you select level 7, for example, then levels 1-7 are all required to use the password to access privileged commands. Example

To restrict access to the show ip interface command, for example, you need to set a password for the desired privilege level and assign that level to the command. In the example that follows, the password Password7 is given to privilege level 7; privilege level 7 is assigned to the show ip interface command. C4# configure enable password Password7 privilege 7 C4# configure privilege exec level 7 show ip interface To confirm the previous command: C4# show privilege exec show ip interface To enter privilege level 7, enter the following command. The CMTS will prompt you for a password: C4# enable 7 Password: Current privilege level for 'show ip route' is 4 Use show users to display the privilege level of defined users. 3 To set the authentication method to the local list of users and passwords: C4# configure authentication testlist1 local Where testlist1 is an example of a name for this method list 4 Configure the telnet and console access to use the authentication method above for enable access: C4# configure line vty 0 6 authentication testlist1 enableauthentication 5 (Example) Set the privilege level to 8 for all configure commands: C4# configure privilege exec level 8 configure 6 (Example) Set the privilege level to 9 for all configure interface cable commands: C4# configure privilege exec level 9 configure interface cable 7 To confirm your changes: C4# show line detail

Displaying Current Privilege Levels

To display the current privilege level you can access based on the password you used, use the following command in User EXEC Mode:

C4> show privilege The system will respond with your current privilege level. Logging In at a Specific Privilege Level

To log into the CMTS at a specific privilege level, use the following command: C4> enable X Where X is number of the privilege level, e.g. 1-15 To exit a specified privilege level, use the following command: C4> disable X Where X is number of the privilege level, e.g. 1-15

Changing Logging Notification Priority Levels

Whenever a command is executed, the default notification priority assigned to that command access level is used to generate a log indicating the execution of that CLI command. Following is a table of the default logging levels for CLI access: Table 2-5: Default Logging Level CLI Access Level

Notification Priority

1-4

7 (Informational)

5 - 15

6 (notice)

You can now indicate at what logging priority you want CLI command execution notifications to be generated. The show logging command displays the CLI access level (same as privilege) and the priority that it comes out as. For example, if you want all config commands (normally privilege level 15) to print at critical level and all show commands (privilege level 1) to print at error level, execute the following commands: configure logging priority cli 15 3 configure logging priority cli 1 4 Creating and Using Command Aliases

2-14

Use the alias command to define shorter simpler versions of commands. Command aliases can save time and can prevent typing errors when you are configuring or monitoring the CMTS.

ARRIS PROPRIETARY — All Rights Reserved

October 9, 2012

2 CLI Overview

C4/C4c CMTS Rel. 8.0.7

Aliases do not persist from one CLI command session to another. You must create a text file in which each alias command appears on a separate line. Save the file with a descriptive name, for example, aliaslist.txt. Use FTP or for greater security use secure FTP (SFTP) to place the alias file to the alias directory: /system/alias/(filename). If necessary, use the following command to enable SFTP: configure ip ssh sftp If the list of alias commands is present in the alias directory and the user has logged in using a defined user profile, then the CMTS automatically executes the alias file. All of the aliases defined in this file are then available. Aliases defined in interactive CLI sessions are not exported to scripts. This means that the script writer must first use the alias command in the script itself to define his/her command aliases before using these aliases in the script. This must be done in every script where the writer intends to use command aliases. These alias definitions are not exported to other scripts or CLI sessions. You can create aliases utilizing the “pipe” character (|) but the CLI command must be in quotes, e.g.: Correct syntax: alias boot “show version detail | include boot” Incorrect syntax: alias boot show version detail | include boot

NO Command

The [no] form of a command is usually used to negate a specific function. Using the [no] form of a command will override all other commands associated with that slot/port, regardless of the parser and regardless of whether or not the parameters were matched. A slot/port with one parameter supports the [no] form automatically. If a slot/port has two or more parameters, you must specify which, if any, is the [no] form.

Pagination

The show and more commands generally display large amounts of data. If you have configured pagination, and output continues beyond what can display on your screen, a --More-- prompt will appear. By pressing any key on your keyboard, the system will display the next screen of output. If you wish to view the output on a line-per-line basis, simply hit the when the --More-- prompt appears. You may at any time hit Q to quit. If pagination has not been configured, you can press to interrupt the show command output.

To turn pagination on, you must be in Privileged EXEC mode and type the following command: C4# configure pagination NOTE Pagination is a per-user command. So, when a new user logs in, he/she will not have pagination turned on; thus, it will never appear in the running-config.

CLI Filtering The CLI filtering feature allows you to search or filter any show or more commands that display system and protocol information. This functionality is useful when you need to sort through large amounts of command output so that you can display only those lines you are interested in. NOTE The filtering function is not available for the command show techsupport. Basic Searching

A regular expression is a phrase, number, or pattern that the CLI filtering feature matches against the show or more command output. For example, to conduct a search on a regular expression of “ power ” (with a space both before and after it) then only lines containing “ power ” will be included in the output. NOTE Normally, regular expressions are case sensitive. The use of regular expressions for the CMTS are case insensitive to make typical searching easier.

2 CLI Overview

C4/C4c CMTS Rel. 8.0.7

How to Use CLI Filtering The CLI permits the following types of filtering: •

Begin - displays output beginning with the first line that contains the text string or regular expression

•

Include - displays output lines that contain the text string or regular expression and excludes lines that do not contain the text string or regular expression

•

Exclude - displays output lines that do not contain the text string or regular expression and excludes lines that do contain the text string or regular expression

•

Until - displays all lines up to and including the first line that matches the given regular expression

•

Count - Counts the number of lines that would have been shown C4# show running-config | count Piped line count: 1557 C4# show running-config | count include cable-mac Piped line count: 60

•

Page - Temporarily turns on paging, in case you have paging turned off but need it for a particular command.

The following CLI options have been added to the show and more commands: [|{begin|include|exclude|until |count |page} [“] regular expression [“]] To use this functionality, enter a show or more command as normal but add a space followed by the “pipe” character (|) at the end of the command line. Then add one of the keywords begin, include, exclude, until, count, or page, along with the regular expression that you want to filter or search on.

Regular expressions can be a single-character pattern that matches the same character in the input string, or multiple characters that match the same multiple characters in the input string.

Special Characters

You can use keyboard characters (such as ! or ~) as single-character patterns, but certain keyboard characters have special meaning when used in regular expressions. The keyboard characters that have special meaning in the CMTS are listed in the Table 2-6:

Table 2-6: Characters with Special Meaning in Search Patterns Character

Special Meaning

.

The dot matches any single character, including white space

*

The asterisk matches any number (or none) of the single character that immediately precedes it. The preceding character can also be a regular expression. E.g., since the . (dot) means any character, then .* means “match any number of any character.”

+

The plus matches 1 or more sequences of the preceding regular expression

^

The caret matches the following regular expression at the beginning of the line.

$

The dollar sign matches the end of the line.

\

The backslash allows for literal meaning of the special characters.

[]

The brackets allow for the definitions of a set of characters to be matched. The brackets also mean the contents will be taken as a single character. (e.g. [aeiou] = any vowel)

[^ ]

Search for anything in the brackets that does not include the set of characters following the caret. (e.g. [^aeiou] = any consonant)

()

The parentheses allow for grouping and recall.

\b

Indicates the beginning/end of a word.

To remove the special meaning of any of the special characters listed in Table 2-6, put a backslash (\) in front of it. For example, when the expression m5\. is used in the command syntax, only the string m5. will be matched.

Issue 2.0

ARRIS PROPRIETARY — All Rights Reserved

2-19

2 CLI Overview

Range

C4/C4c CMTS Rel. 8.0.7

A range is a sequence of characters enclosed in brackets [ ]. It normally matches any single character from the sequence. When the sequence begins with a caret (^), it matches any single character not from the rest of the sequence. When two characters in the sequence are separated by a hyphen (-), this is shorthand for the full list of ASCII characters between them. For example, [0-9] matches any decimal digit. To include a literal bracket “]” in the sequence, make it the first character, following a possible caret. To include a literal hyphen (-), make it the first or last character. A backslash “\” followed by a single character, includes that character, however, backslashes are not necessary for most special characters, as inside a range, only the “]”, “-”, and “\” characters are treated specially. The bracket [ ] characters allow for the definitions of a set of characters to be matched. The brackets also mean the contents will be taken as a single character. For example, the following expression matches with a, e, i, o, u: [aeiou] Use the hyphen (-) character inside the square brackets to mean all the characters from the character preceding the hyphen to the character following it. For example, [0-9] is the same as [0123456789]. Also, [af] is the same as [abcdef]. The following matches a hexidecimal digit: [09a-f]. NOTE When using the hyphen (-), do not mix types. Examples of bad ranges include: [7-k], [&-%], [D-e]. The [D-e] is equivalent to [D-Za-e] which is equivalent to [a-z] because the CLI is case insensitive.

Multiple-Character Patterns

Regular expressions can also specify patterns containing multiple characters. You create multiple-character expressions by joining letters, digits, or keyboard characters that do not have special meaning. Order is important in multiple-character patterns. The expression m5& matches the character m followed by a 5 followed by a & sign. If the string does not have m5&, in that order, the pattern matching fails. The multiple-character expression a. uses the special meaning of the period character to match the letter a followed by any single character. With this example, the strings ab, a!, or a2 are all valid matches for the expression.

Wildcard Searches

To emulate a wildcard search, the expression must match any character. For this, regular expressions use the period (.) character. For example, the following regular expression matches ARRIS followed by any single character: ARRIS.

2-20

ARRIS PROPRIETARY — All Rights Reserved

October 9, 2012

2 CLI Overview

C4/C4c CMTS Rel. 8.0.7

The asterisk (*) in the wildcard search can match with no characters or any number of characters. For example, the following regular expression does exactly the same as the wildcard pattern above: ARRIS.* When you use an asterisk (*), it means none, one, or more of the previous character in the pattern. In the example, the asterisk is preceded with a period, which means none, one, or more of any character. Multipliers

You can create more complex regular expressions that instruct the software to match multiple occurrences of a specified expression. Table 2-7 lists special characters that specify “multiples” of an expression. Table 2-7: Special Characters Used as Multipliers Character

Special Meaning

*

The asterisk matches any number (or none) of the single character that immediately precedes it. The preceding character can also be a regular expression. E.g., since . (dot) means any character, then .* means “match any number of any character.”

+

The plus matches 1 or more sequences of the preceding regular expression

Examples: To match any number of occurrences of the letter m, including none: m* To require that at least one letter m be in the string to be matched: m+ By enclosing the pattern in parentheses you can use multipliers with multiple-character patterns. The parentheses () characters are used to see this pattern as one character. In the following example, the pattern matches any number of the multiple-character string mn: (mn)* Some useful example patterns that might be helpful: Any IP address = [0-9]+\.[0-9]+\.[0-9]+\.[0-9]+ Any MAC address = [0-9a-f][0-9a-f][0-9a-f][0-9a-f]\.[0-9a-f] [0-9a-f][0-9a-f][0-9a-f]\.[0-9a-f][0-9a-f][0-9a-f][0-9a-f] Alternation

Alternation allows you to specify alternative patterns to match against a string. You separate the alternative patterns with a vertical bar (|). Either one of the alternatives can match the string.

You can match an expression pattern against the beginning or the ending of a string. By specifying that the beginning or ending of an input string contains a specific pattern, you “anchor” these expressions to a portion of the string using the special character shown in the following table. Table 2-8: Special Anchoring Character Character ^

Description The caret matches the beginning of the string

This is another use for the ^ symbol. In this example, the following regular expression matches an input string only if the string starts with 1234:

^1234 The next example shows that the following regular expression is a range that matches any single number, as long as it is not the numbers 1, 2, 3, or 4: [^1234] Parentheses for Recall

You can use parentheses () with multiple-character regular expressions to multiply the occurrence of a pattern. You can also use parentheses around a single or multiple-character pattern to instruct the software to remember a pattern for use elsewhere in the regular expression. To create a regular expression that recalls a previous pattern, you use parentheses to instruct memory of a specific pattern and a backslash (\) followed by an integer to reuse the remembered pattern. The integer specifies the occurrence of a parentheses in the regular expression pattern. If you have more that one remembered pattern in your regular expression, then \1 uses the first remembered pattern and \2 uses the second remembered pattern, up to nine. The following regular expression uses parentheses for recall: a(.)bc(.)\1\2 This regular expression matches the letter a followed by any character (call it character #1) followed by bc, followed by any character (character #2), followed by character #1 again, followed by character #2 again. In this way, the regular expression could match azbctzt. The software identified character #1 as z and character #2 as t and then uses z and t again later in the regular expression. As you will notice, the parentheses do not change the pattern; they only instruct the software to recall that part of the matched string. Following is an example of advanced regular expression using double parentheses: ((19.*) (slot|interface))

C4/C4c CMTS Rel. 8.0.7

Show Cable Modem Column Feature With each release, the show cable modem command must support additional information because the list of features is expanding. Unfortunately, this command is already extremely wide and prompted us to develop a feature that would allow the user to specify exactly which columns they wish to see and which ones they don’t. This feature will allow the user to create their own output, thus maximizing their screen space and run-time. This is useful for not only interactive use but also for scripts. The show cable modem command, for instance, displays receive power and timing offset for each modem — both of which require a relatively slow access to the CAM for every modem. By eliminating the receive power and timing offset from the output, this command runs up to three times faster. Command Parameters

limitation, the CLI cannot currently support the following syntax without circumventing the existing infrastructure: C4# show cable modem column . . slot 4 To reach this goal, additional syntax has been designed to give the desired flexibility: C4# configure cable modem format .. C4# show cable modem format slot 4 So, using a format name as a handle or shorthand for column output was seen as the best way to accomplish the goal of allowing the user full control over the filtering, sorting, and output functions of show cable modem. You can define formats and then create an alias for show cable modem format which would allow the user to pass parameters using the alias. Help Enhancements

Due to the large number of columns that the CMTS supports, it was thought that a listing of the available parameters would be more helpful than a full description. This command is modeled after the show cable modem vendor ? command help output which just displays a list of vendors. The show cable modem column ? command will list only the available parameters and the output would look similar to the output below: C4# show cable modem column ?

CLI

Command Descriptions

This chapter provides detailed descriptions of each of the CMTS CLI commands. The CLI commands are organized alphabetically and apply to both the C4 CMTS and the C4c CMTS unless specified. When you log in to the CLI, you are in User EXEC mode. User EXEC — User EXEC commands are used for everyday system monitoring. They allow you to change terminal settings on a temporary basis, perform basic tests and show system information. The prompt C4> indicates User EXEC mode and the default access level is 1. The User Show commands are part of the User EXEC mode. The prompt will be C4> as in the User EXEC mode. The User Show commands display system information. The default access level of User Show commands is 1. Privileged EXEC — The Privileged EXEC mode commands are used to set operating parameters. If a Privileged EXEC password exists, the CLI prompts you to enter it to gain access. The password does not appear on the screen. Privileged EXEC mode includes the User EXEC commands. To enter Privileged EXEC mode, enter the enable command at the C4> prompt. The prompt changes to C4#. If no enable password is configured, any user may enter Privileged EXEC mode without authentication. The default access level of Privileged EXEC mode commands is 15. Global Configuration — Global Configuration commands apply to features that affect the entire system. These commands apply to system features and enable routing functions. Enter configure at the command prompt in Privileged EXEC mode to enter the Global Configure mode. The prompt will change to C4#. To return to Privileged EXEC mode, enter quit, exit or press Ctrl+Z. NOTE In the command headings the asterisk (*) represents one or more variables that have been omitted to save space and to make the heading more readable. All the pertinent variables are found in the command syntax line.

alias Default Access Level

Mode

Non-privileged – 1

User EXEC

Purpose

The alias command is used to create abbreviated versions of CLI commands. If the command is entered without any parameters, it simply displays a list of all existing aliases. To remove a specific alias, use the [no] option. There is a size limitation associated with the alias buffer. The alias limit may be reached in two ways; via the alias count, currently 256, or via the alias buffer size which is 8192 characters in length. The alias buffer size consists of all the alias names and their associated commands concatenated together. For example, you could reach the alias limit with just 81 aliases if each alias name/command has a length of 100 characters. NOTE The aliases you create do not persist in memory after the user session is closed. Aliases can be saved to a file and that file can be called in from a user’s profile. In this manner, a user can have a particular set of aliases that become available each time he or she logs in. Alternatively, the user can save to a file and manually load this file of aliases upon logging in.

Syntax

alias [ ] [no]

Parameter

Definition

[

The abbreviation or replacement name to be used as an alias for a CLI command.

]

The CLI command that the CMTS will execute when the alias is entered from the command line.

NOTE Currently, the CM Deny List MIB table will accept no more than 1000 MAC addresses. The configure reset cable-modem command can then be entered to remove the modem(s) from the queue. -orBy waiting for the C4 CMTS T9 timer to automatically expire within 15 minutes, the C4 CMTS will remove the modem(s) from the ranging queue. To remove the specified MAC address from the CM Deny List MIB, use the [no] option.

Purpose

Sets the interval between successive sync message transmissions in milliseconds. The sync messages allow a cable modem to lock into the 10.24 MHz system clock in the CMTS.

Interface Cable-mac Configuration

Purpose

Enables cable modems to provide verbose reporting of Receive Channel Profiles (RCP). To disable verbose reporting, use the [no] option. By default RCP reporting is set to non-verbose. RCP reporting is part of the algorithm used by the CMTS to assign RCC (Receive Channel Configurations) to cable modems. If verbose reporting of RCPs is enabled, CMs send their full Receive Channel Profiles to the CMTS. If it is not enabled (non-verbose RCP reporting), then CMs send only their RCP IDs. If the CMTS does not recognize a particular RCP ID, it uses a standard DOCSIS-defined RCP for that modem instead. Dynamic RCC channel assignments must operate with hard-coded RCPs because there are no RCP MIBs to support them. Conforming verbose RCPs must satisfy these criteria:

Syntax

•

Nx1 receive channel configuration where all receive channels connect to a single receive module

•

NxN receive channel configuration with receive channel connectivity:

•

- Rx channel 1 -> Rx Module 1 - Rx channel 2 -> Rx Module 2 - Rx channel 3 -> Rx Module 3 - Rx channel N -> Rx Module N They do not require common PHY parameter checks

•

They do not specify multiple frequency blocks per module

•

They do not specify any module-to-module connectivity requirements

•

They do not support module resequencing subset limitations

Interface Cable-mac Configuration

Purpose

Sets the interval at which hello packets must not be seen before neighbors declare the router down. To disable OSPF dead-interval, use the [no] option. In OSPF operation the dead interval must be greater than the hello interval. It is recommended that the dead interval be set to a value greater than two times the hello interval. Defaults:

Syntax

hello interval = 10 seconds; dead interval = 40 seconds.

configure interface cable-mac ip ospf dead-interval [no]

Parameter



Definition

The MAC identifier. Link state metric with value range from 0 to 65535. Default = 40.

Fast Hello Functionality — When the dead interval is set to one second, Fast Hello timers are used. The ospfPmIfFastHelloMultiplier MIB object is used to determine the hello interval instead of the configured hello interval value. This object determines the number of OSPF HELLO packets that should be sent within one second. The default value is 5 packets and is not configurable. Thus, if you set the dead interval to one second, then you automatically change the hello interval to 200 ms. CAUTION

Any user wishing to enable Fast Hello functionality must first contact ARRIS Technical Support to determine if it is feasible for his/her site. Changing the dead interval to any value greater than one second disables the Fast Hello timers. The ospfPmIfFastHelloMultiplier MIB object is no longer used.

Purpose

Configures the number of IS-IS hello packets a neighbor must miss before the router declares the neighbor down on the specified interface. This determines how quickly a failed neighbor is detected so that routes can be recalculated. The advertised hold time in IS-IS hello packets will be set to the hello multiplier times the hello interval. Neighbors will declare an adjacency to this router down after not having received any IS-IS hello packets during the advertised hold time. The hold time can be set on a per-interface basis and can be different between different routers in one area. To restore the default value, use the [no] option. NOTE Using a smaller hello multiplier will give fast convergence, but can result in more routing instability. Incrementing the hello multiplier to a larger value will help stabilize the network. Never configure a hello multiplier lower than the default value of 3.

Purpose

Causes all notifications with specified priority to be sent to the Syslog server (if an IP address has been configured). NOTE By default, the C4 CMTS routes any event with priority emergency (1), alert (2), critical (3), error (4), warning (5), or notice (6) to the Syslog server. However, to send other priority levels to Syslog or SNMP, they must first be enabled for the local volatile log or local non-volatile log. The same set of priorities are enabled for SNMP and local-volatile by default. Local-nonvolatile has no priorities enabled by default. Also by default, the C4 CMTS sends all Syslog messages to the Syslog facility local0. The facility may be changed to local1, local2, local3, local4, local5, local6, or local7. The C4 CMTS will not route events to a Syslog server unless the server’s IP address is configured.

configure qos-sc name Default Access Level

Mode

Privileged – 15

Global configuration

Purpose

Configures a Quality of Service (QoS) service class. To remove the QoS service class, use the [no] option.

Syntax

configure qos-sc name [no]

Parameter

Definition



A predefined Quality of Service configuration referred to by the cable modem in a configuration file and used to encode a Service Flow according to the parameter values found in the SCN. The maximum length = 15 characters.

[priority ]

Allows service flows to be given priority for delay and buffering. The C4 CMTS uses this field to assign traffic priorities, which are implemented using a queuing system.

[max-tr-rate ]

Specifies the rate parameter R of a token-bucket-based rate limit for packets. R is expressed in bits per second. This rate expresses an upper boundary, not a guarantee that the rate is available.

[max-tr-burst ]

Specifies the token bucket size B (in bytes) for this Service Flow.

Specifies the minimum rate, in bits/sec, reserved for this Service Flow. If [min-res-rate ] CM requests less bandwidth than this minimum, the C4 CMTS may reallocate the excess. [min-res-pkt ]

Specifies an assumed minimum packet size (in bytes) for which the Minimum Reserved Traffic Rate will be provided.

[peak-tr-rate ]

Specifies peak traffic rate shaped.

[max-burst ]

Specifies the maximum concatenated burst (in bytes) which a Service Flow is allowed. This parameter is calculated from the FC byte of the Concatenation MAC Header to the last CRC in the concatenated MAC frame

[poll-int ]

Issue 2.0

Specifies the nominal interval (in units of microseconds) between successive unicast request opportunities for this Service Flow on the upstream channel. This parameter is typically suited for Real-Time and Non-Real-Time Polling Service.

CLI-925

CLI Command Descriptions

C4/C4c CMTS Rel. 8.0.7

Parameter

Definition

[poll-jitter ]

Specifies the maximum amount of time that the unicast request interval may be delayed from the nominal periodic schedule (measured in microseconds) for this Service Flow.

[grant-size ]

Specifies the unsolicited grant size in bytes

[grant-int ]

Specifies the nominal interval (in units of microseconds) between successive data grant opportunities for this Service Flow. Required for UGS and UGS/AD

[grant-jitter ]

Specifies the maximum amount of time (in microseconds) that the transmission opportunities may be delayed from the nominal periodic schedule for this Service Flow. Required for UGS and UGS/AD

[grant-per-int ]

For UGS, the value of this parameter indicates the actual number of data grants per NominalGrant Interval. For UGS/AD, the value of this parameter indicates the maximum number of Active Grants per Nominal Grant Interval. This is intended to enable the addition of sessions to an existing UGS Flow via the Dynamic Service Change mechanism, without negatively impacting existing sessions.

[max-lat

Maximum downstream latency — a service commitment by CMTS to forward a packet received on a network side interface to the RF interface within the specified number of microseconds.

[active-tmout ]

Specifies the maximum duration resources remain unused on an active Service Flow. If there is no activity on the Service Flow within this time interval, the CMTS MUST change the active and admitted QoS Parameter Sets to null.

[adm-tmount ]

Specifies the duration that the C4 CMTS MUST hold resources for a Service Flow’s Admitted QoS Parameter Set while they are in excess of its Active QoS Parameter Set.

[type ]

Specifies the service class schedule type. Valid types: 2 - Best Effort schedule type 3 - Non real time polling service schedule type 4 - Real time polling service schedule type 5 - UGS with activity detection schedule type 6 - UGS schedule type

[req-policy ]

Specifies which IUC opportunities the CM uses for upstream transmission requests and packet transmissions for this Service Flow, whether requests for this Service Flow may be piggybacked with data and whether data packets transmitted on this Service Flow can be concatenated, fragmented, or have payload headers suppressed.

[and-mask ] [or-mask ]

IP Type of Service overwrite. Enables CMTS to overwrite original Type of Service (ToS) byte with new value.

[required-attr-mask-value ]

Specifies the attribute mask required for the service flow. Value is a hex string between 0x00000000-0xFFFFFFFF.

CLI-926

ARRIS PROPRIETARY — All Rights Reserved

October 9, 2012

CLI Command Descriptions

C4/C4c CMTS Rel. 8.0.7

Parameter

Definition

[forbidden-attr-mask-value ]

Specifies the attribute mask that is not allowed for the service flow. Value is a hex string between 0x00000000-0xFFFFFFFF.

[dir]

The service flow direction. Downstream is 1 and upstream is 2.

[latency-scheduler

Example

Enables or disables latency controlled flow.

Following is an example of configuring the QoS class: C4#

configure qos-sc name SCNA priority 0 max-tr-rate 500000 max-tr burst 3044 min-res-rate 0 min-res-pkt 0 max-burst 0 poll-int 0 poll-jitter 0 grant-size 0 grant-int 0

Purpose

Specifies which specific routes are not to get aggregated. However, the attributes of the suppressed specific routes are inherited by the aggregate route. The attribute-map can be used to override the inherited attributes. The nonsuppressed specific routes would be advertised out in addition to the aggregate route. Removing the option “as-set” would cause the aggregate route not to inherit the AS_PATH attributes from the specific routes. To disable, use the [no] option.

ping Default Access Level

Mode

Non-privileged – 1

User EXEC

Purpose

The ping (Packet Internet Groper) command is a common method of troubleshooting the accessibility of devices. It sends a series of Internet Control Message Protocol (ICMP) echo-request packets to determine if a remote host is active or inactive. It also provides the round-trip delay in communicating with the host. NOTE If you specify the System Control Module’s (SCM’s) IP address with the ‘source-ip A.B.C.D.’ optional parameter, the source IP address for the ICMP packet will be the SCM’s IP address. The ping is successful only if the echo request gets to the destination and the destination is able to reply back to the source. Press ^C (the control key + C combination) to stop the ping process.

Syntax

ping [source | hostname] [repeatcount ] [timeout ] [size ] [tos ] [ttl ] [payload ] [validate]

Parameter

[source ] [repeat-count ]

Definition

Destination IP address (in the form A.B.C.D.) of the source ping packet Source IP address of the ping packet. Number of packets to send. Maximum value for repeat count is 32768. Default is 5.

[timeout ]

Specifies the timeout in seconds that the ECHO REPLY response should be received in response to the ECHO REQUEST. Range is 1 to 255. Default is 2.

[size ]

Specifies the datagram size in bytes. The range is 100 to 1480. Default is 100.

[tos ]

Specifies the type-of-service in the IP header of each ECHO REQUEST packet. Range is 0 to 255. Default is 0.

[ttl ]

Time-to-Live for the packet. Range is 1 to 255. Default is 64

[payload ] ICMP payload pattern in hex (e.g. ab, a9, 99) [validate]

Privileged EXEC

Purpose

Reloads the CMTS from the file specified in the update partition. If no file name is specified then the current active image is reloaded. If the retain-patches keyword is used, the system performs the reload without first removing the existing patch files from the C4 CMTS disk. NOTE Any image booted using the reload update command is temporary, unless it is committed. If the system reboots for any reason while executing a reload update, it automatically reverts to the active partition image thereby backing out the update image.

Syntax

Purpose

If the system is active and modems are registered, this command will make the current running image the active image (includes an automatic write memory) which will maintain the new image across system reboots. If the executing image is the active image on the active partition and all firmware is up-to-date, this command does nothing. If the executing image is an update image on the update partition, firmware on all modules is programmed to non-volatile memory and the image is simply copied to the active partition. NOTE Committing a new image and new firmware can take up to 40 minutes to complete. The commit process runs in the background and does not impact service.

Syntax

Example

To commit the new image and firmware, use the following command: C4#>

By default, this command will output all modems with non-zero flap counts sorted by CM MAC address.

show cable load-balance policy Default Access Level

Mode

Non-privileged – 1

User EXEC

Purpose

Displays the provisioning for the load balance policies in a table format. Since there is a good deal of provisioning for each policy and it is important to be able to see how the load-balance policy provisioning differs from each other, the provisioning is displayed in a table format. NOTE If the policy number is provided, then the table is shown with only rules associated with the one policy. If no provisioning is found for a provided policy number, then the show command will generate an error indicating that the policy number could not be found. If no policies are provisioned, then an error is generated indicating no policies were found.

Syntax

show cable load-balance policy []

Parameter

Definition

[]

The policy number

Example

To display the provisioning for the load balance policy, use the following command: C4>

show cable load-balance policy The following is an example of the output returned by the system:

Table CLI-12: Column Headings for Load Balancing Statistics Column

Description

Interface

US or DS channel that is part of a load balance group.

Oper State

Operational State: service state of the channel.

LBal State

Load Balancing State: whether load balancing is enabled or disabled for the load balance group.

Group

Load Balance Group number. This number is assigned by the CMTS for a general group or provisioned by the user for a restricted group.

Init Tech

Dynamic Channel Change (DCC) Initialization Technique

Load

%Util

Traffic load on this channel calculated as a percentage of Channel utilization for upstreams computed by number of minislots used by the map maker for unicast grants divided by the total number of minislots available over a fixed time interval. DS channel utilization is computed as total bytes sent divided by the total available bandwidth over the measurement interval. The channel with the greatest utilization moves a modem to the channel with the least.

Count

Number of CMs per channel. The choice of the CM to be moved is determined by the provisioned values of load balance priority and load balancing policy ID. If these values are equal, then a CM is chosen randomly to be moved from the channel with the most CMs to the channel with the least.

Load

Dynamic Transfer

Static Transfer

CLI-1312

In The number of modems that have been moved as a result of Dynamic Load Out Balancing. The number of modems that have been moved as a result of Static Load In Balancing. Static load balancing can occur only when a modem is ranging. Out Static load balancing applies only to upstream channels. Downstream interfaces (channels) show only dashes (null counts) for static load balancing.

C4/C4c CMTS Rel. 8.0.7

In the first line of the output, there are two references to DOCSIS: •

The first one is the CM capability - taken from modem capabilities that the modem sends up in the registration request.

•

The 2nd is the type that the CM is configured to use - taken from the registration DOCSIS style of the registration request - DOCSIS 1.0 if no QoS, DOCSIS 1.1 if QoS.

The noLoadBal flag will be set to 1 if the CM has one or more static, provisioned US UGS flows in the CM config file. This is an indication that this modem will not be DCC'ed during load balancing. During a dynamic load balancing operation, noLoadBal is a bit map of reasons why this SM should not be moved. The dsPartialServMask is a bit map of 16 bits indicating which downstream channels were not acquired by a DS channel bonding capable CM during registration. The least significant bit represents downstream port 0 on a DMM and the most significant bit represents downstream port 15 on a DMM. The usPartialServMask is a bit map of 24 bits indicating which upstream channels were not acquired by a US channel bonding capable CM during registration. For each US and DS service flows: •

A letter B under the u/d column indicates a bonded service flow.

•

A letter 'C' indicates that it's a non-bonded US service flow with single channel but segment headers are enabled, i.e. MTCM CCF is on.

•

A “-” after the SFID is displayed to indicate a failure status for service flow assignment to a bonding.

•

A () around the ports for upstream and downstream indicates that the port is impaired.

C4/C4c CMTS Rel. 8.0.7

Table CLI-13: Explanation of Current CPE and Max CPE Output Element

Explanation Maximum count of all MAC addresses that can be linked behind the CM. The value of “Max CPE” is enforced by the CM, not the CMTS. This is in accordance with the MULPI spec.

Max CPE = 16

The value can be defined in the registration request TLV 18 MAX CPE or it can be constrained due to hardware limitations. If the TLV is missing or set to a value of zero, the actual MAC limiting value the CM uses defaults to 1, and “Max CPE=1” is displayed. If the TLV contains a value from 1 to 32, the CM limits MAC count from 1 to 32 respectively, and “Max CPE=32” is displayed. If the TLV contains a value greater than 32, the CMTS will limit MAC count per CM to 32 (the hardware defined limit), and “Max CPE=32” is displayed.

IPv4 Addr=32

Maximum count of total number of IPv4 addresses that can be assigned across all CPEs behind the CM. This count is configurable using the configure cable submgmt default max-cpe command. It takes effect only if submgmt is enabled (configure cable submgmt default active).

IPv6 Addr=64

Maximum count of total number of IPv6 addresses that can be assigned across all CPEs behind the CM. This count is configurable using the configure cable submgmt default v6-max-cpe command. It takes effect only if submgmt is enabled (configure cable submgmt default active).

NOTE There can be an apparent discrepancy between the QoS value displayed by the show cable modem command and the Tmax values of the show cable modem detail command. This is because the QoS value is the sum of the Tmax values of the service flows. If there is a service flow with a Tmax of 0, then the QoS will be displayed as 0.

show cable modem summary Default Access Level

Mode

Non-privileged – 0

User EXEC

Purpose

Displays a summary of the number of modems that are on each interface and the overall system. It displays counts but does not display any information about a particular modem. In the case of bonded modems, the count for each port will be equal to the number of modems on that port since a single bonded modem will be on multiple ports. The totals represents the number of modems, not channels, therefore, the sum of the ports should equal or be greater than the total number of modems. Summaries are given per slot as well as per cable-mac.

Syntax

The example shows: Prio

Corresponds to the priority in which the MAC scheduler processes bandwidth requests from the cable modems. These priorities are related to the Upstream Traffic Priority TLV specified in the cable modem configuration file. The following table illustrates this relationship: BW Request PriorityUpstream Traffic Priorities 1 2 3 4 5

Need

UGS (not applicable) 6 and 7 4 and 5 2 and 3 0 and 1

Each Bandwidth Request priority has 3 queues. They are called Needy, Normal, and Greedy for a total of 12 Bandwidth Request priority queues processed by the MAC scheduler. Subscribers who use most of their assigned bandwidth are classified as Greedy while those who use bandwidth only once in a while are classified as Needy. All other subscribers are classified as Normal.

Needy subscribers have the highest priority requesting bandwidth while Greedy subscribers will have the lowest. Therefore, a low priority Needy subscriber will receive an upstream grant earlier than a Normal subscriber and a Normal subscriber will get an upstream grant quicker than a Greedy subscriber. Number Adds

For each Bandwidth Request priority Queue, the total number of bandwidth requests added to this queue. This includes requests promoted from lower priority queues.

Number Pendings

For each Bandwidth Request priority Queue, the total number of grant pendings given to bandwidth requests on this queue.

Number Promos

For each Bandwidth Request priority Queue, the total number of bandwidth requests promoted from this queue to a higher priority (less greedy) queue.

Number Drops

For each Bandwidth Request priority Queue, the total number of requests dropped. These are dropped primarily for pending for too long or too many grants pending per map.

Number Elements For each Bandwidth Request priority Queue, the current number of bandwidth requests in the queue. Average Latency (sum(BwRequestQueuesLatencySum) / (sum(BwRequestQueuesNumAdds) (sum(BwRequestQueuesNumPromos)

Example

Definition

Displays detailed neighbor information.

Sys Adj System ID Interface SNPA State Hold Type Type Circuit Id Protocol -------------- ---------------------- -------------- ----- ----- ---- ---- ------------------- -------0100.8500.9001 gigabitEthernet 17/9.0 000b.45b6.0100 Up 9 L1/2 L1 TR11.01 M-ISIS 0100.8500.9001 gigabitEthernet 17/9.0 000b.45b6.0100 Up 9 L1/2 L2 TR11.01 M-ISIS

NOTE If the connected router does not support MT IS-IS, the protocol will display IS-IS in the above output. If the neighbor row says ‘IS-IS’, it only indicates that the remote IS is using regular IS-IS TLVs on that interface. The CMTS can still send MT TLVs based on its own system/interface configuration. The CMTS’s MT support can be verified using the show isis protocol command. Example

To display the IS-IS neighbor detail output which includes both the remote router’s protocol (M-ISIS or IS-IS) and the remote router’s topologies (IPv4 and IPv6), use the following command: show isis neighbor detail

traceroute Default Access Level

Mode

Non-privileged – 1

User EXEC

Purpose

Determines the path a packet takes to get to a destination. The device sends out a sequence of User Datagram Protocol (UDP) datagrams to an invalid port address at the remote host. Three datagrams are sent initially, each with a Time-To-Live (TTL) field value set to one. The TTL value of 1 causes the datagram to “timeout” as soon as it hits the first router in the path. A response is then received with an ICMP Time Exceed Message (TEM) indicating that the datagram has expired. NOTE The configure ip vrf default icmp-time-exceeded command must be run or traceroute through the CMTS will not work Another three UDP messages are now sent, each with the TTL value set to 2 which causes the second router to return ICMP TEMs. This process continues until the packets actually reach the other destination. Since these datagrams are trying to access an invalid port at the destination host, ICMP Port Unreachable Messages are returned, indicating an unreachable port, this event signals the Traceroute program that it is finished. Traceroute can also execute from the System Control Module ethernet port. If the source-ip option specifies the SCM’s IP address, then the traceroute will be sourced from the SCM’s ethernet port. The purpose behind this is to record the source of each ICMP Time Exceeded Message to provide a trace of the path the packet took to reach the destination from a given source by returning the sequence of hops the packet has traveled.

[timeout ]

Specifies the timeout in seconds for each ICMP echo request “probe”. Range is 1 to 100 seconds. Default is 3.

[probe-count ]

Specifies the number of “probes” to send at each TTL level. The range is 1 to 10 probes. Default is 3.

[min-ttl ]

Specifies the starting TTL for the traceroute (first probe). This is used to start the traceroute beyond the known hops en route to the destination. Range is 1 to 64 hops. Default is 1.

[port-number ]

Specifies the starting destination port number. The port number increments by 1 for each “probe”. Range is 1 to 65535. Default is 33434.

[tos ]

Differentiated Service Class (TOS) field type of service [0] [0-255]. Default is 0.

This document describes the CMTS Simple Network Management Protocol (SNMP) enterprise Management Information Base (MIB) variables. The enterprise MIBs described in this chapter are created for the CMTS, as opposed to the MIBs defined by the DOCSIS® standards. Simple Network Management Protocol (SNMP) is used to configure the CMTS. The CMTS is fully SNMP manageable. DOCSIS® requires that the CMTS and cable modems (CM) implement many MIB tables as defined in various Request for Comments (RFCs). Additional private MIB tables have been defined to represent the hardware and software architecture of the CMTS. NOTE To manage a CMTS, the CMTS IP address must be either discovered (via SNMP discovery) or entered manually.

Each community string defined in snmpCommunityTable can be configured with one access list number. For each community string associated with an access list number, the incoming SNMP request is permitted or denied using standard access list filtering. For more information, see configure access-list * remark on page CLI-93, and similar commands. configure snmp-server community configure snmp-server community no An SNMP community or v3 user consists of 3 parts: views, groups, and users View — defines the portion of the overall MIB tree that is visible to an SNMP user. Views are configured by using the “snmp-server view …” commands. These commands map directly to the SNMP MIB table “vacm-

ViewTreeFamilyTable” as explained in RFC3415. The CLI commands for creating/modifying/deleting views are as follows: configure snmp-server view included configure snmp-server view excluded configure snmp-server view no The MIB-family is specified as a full object-identifier i.e. “1.3.6”. For example, to define a view that includes internet, but excludes private, use the commands: configure snmp-server view testview 1.3.6.1 included configure snmp-server view testview 1.3.6.1.4 excluded

of access read/write/notify. These commands map directly to the SNMP MIB table “vacmAccessTable” as explained in RFC3415. The CLI commands are: configure snmp-server group v1 [read ] [write ] [notify ] configure snmp-server group v2c [read ] [write ] [notify ] configure snmp-server group v3 [read ] [write ] [notify ] configure snmp-server group no configure snmp-server group v3 no The read, write, and notify views are each optional: if no ‘write’ view was specified then the group defines read-only permissions. For example: configure snmp-server group testgroup v3 noauth read testview User — Refers to the person that uses the client to access the SNMP server. The user can be of type SNMPv1, SNMPv2, or SNMPv3. SNMPv3 will be discussed later. These commands map directly to the SNMP MIB table “vacmSecurityToGroupTable” as explained in RFC3415. The CLI commands are: configure snmp-server user configure snmp-server user no For example: configure snmp-server user testuser testgroup v2c NOTE In order for the v1/v2c user to be utilized through SNMP, there must exist a corresponding community in the SNMP MIB table “snmpCommunityEntry”(RFC3416). The username testuser maps to the security name.

3-12

ARRIS PROPRIETARY — All Rights Reserved

3 Standard and Cadant Enterprise MIBs

C4/C4c CMTS Rel. 8.0.7

The community entry can be modified manually using the commands: configure snmp-server community [security ] For example: configure snmp-server community public security testuser The following command disables the community name testuser: configure snmp-server community testuser no NOTE The community name doesn’t have to be the same as the user name. If they are different, then it is the community name that needs to be sent in the SNMP message from the client and not the user name. The user must be associated with a group of the same type (either v1 or v2c) in order for it to work. The transport tag value in the command string below identifies an entry in the snmpTargetAddrTable whose snmpTargetAddrTagList contains this tag value. If an SNMP management request containing this community is received on a transport endpoint other than the transport endpoints identified by tag value, the incoming SNMP request is inauthentic. (reference: RFC3416) configure snmp-server community ttag The community index specifies the index in the snmpCommunityTable. It identifies an entry in the table. configure snmp-server community index Basic configuration for an SNMP v3 user

SNMPv3 users can be setup with or without authentication enabled. If authentication is enabled, privacy may also optionally be enabled. These commands map directly to the SNMP MIB table “usmUserTable” as explained in RFC3414. The CLI commands are: configure snmp-server user v3 [auth [priv ]] configure snmp-server user v3 no

For example: configure snmp-server user “v3user” “v3group” v3 auth sha “password1” priv “password2” The same principle of group view associations applies to v3 users as well as v1/v2c users. NOTE A v3 user must be associated with a v3 group. You cannot associate a v3 user with a v1 or v2c group. Configuring different notification-types

To enable/disable SNMP Authentication Failure Trap, use the following commands: configure snmp-server enable traps snmp configure snmp-server enable traps snmp no

Configuration of SNMP Notification receivers

The CLI commands for creating/modifying/deleting hosts are as follows: configure snmp-server host N.N.N.N traps [udp-port [timeout [retry ]]] configure snmp-server host N.N.N.N informs [udp-port [timeout [retry ]]] The two commands above map directly to the SNMP MIB table “snmpTargetAddrTable” as explained in RFC3413. The taglist is used to specify a list of tags as defined in the snmpNotifyTable. It is formatted as a list of 1 or more strings separated by whitespace. If more than one tag is used, then the list must be enclosed in quotes. The following command provides the syntax: configure snmp-server host N.N.N.N taglist [udpport [timeout [retry ]]] For example: configure snmp-server host 10.33.4.120 taglist "InformTag TrapV2Tag" timeout 500 retry 3

For example, to configure a host to receive both traps and informs: configure snmp-server host “10.1.1.1” traps configure snmp-server host “10.1.1.1” informs configure snmp-server host N.N.N.N no The tparam specifies the target parameters name defined in the snmpTargetParamsTable. The identified entry in the snmpTargetParamsTable contains SNMP parameters to be used when generating messages to be sent to this transport address. configure snmp-server host N.N.N.N tparam The target address name specifies the index in snmpTargetAddrTable. It identifies an entry in the table. configure snmp-server host N.N.N.N name The mms specifies the maximum message size. It is used to determine the maximum message size acceptable to another SNMP entity when the value cannot be determined from the protocol. configure snmp-server host N.N.N.N mms The mask value allows selected entries in the snmpTargetAddrTable to specify multiple addresses. This would typically be used to specify a subnet in an snmpTargetAddrTable rather than just a single address. The mask value is used to select which bits of a transport address must match bits of the corresponding instance of the snmpTargetAddrTAddress, in order for the transport address to match a particular entry in the snmpTargetAddrTable. The value of an instance of snmpTargetAddrTMask must always be an OCTET STRING whose length is either zero or the same as that of the corresponding instance of snmpTargetAddrTAddress. The mask is not used in generating notifications. When generating notifications, entries in the snmpTargetAddrTable only specify individual addresses. (reference: rfc3416) configure snmp-server host N.N.N.N mask (Example 1) Configure a mask to specify a subnet of 10.44.xx.xx with udp-port of 161: configure snmp-server host 10.44.0.0 udp-port 161 mask ff:ff:00:00:ff:ff

(Example 2) Configure a mask to specify a subnet of 10.43.8.xx with any udp-port: configure snmp-server host 10.43.8.0 mask ff:ff:ff:00:00:00 Configuration of SNMP Notification filters

A notification-security-model may optionally be configured with an associated filter in order to restrict the trap types that can be generated using a particular model. The commands to create a filter are very similar to the commands used to create an SNMP view. Use the following commands to create filters: configure snmp-server notify-filter [profile ] [subtree ] [type ] no configure snmp-server notify-filter [profile ] [subtree ] These commands map directly to the SNMP MIB table “snmpNotifyFilterTable” as explained in RFC3413. The syntax of the parameters is similar to the “snmp-server view …” commands explained in section 4.1.1.1 of the RFC.

DOCSIS 2.0 Compliance In December, 2004, the C4 Cable Modem Termination System (CMTS) received DOCSIS® 2.0 requalification by CableLabs® with the new software upgrade designed to support DOCSIS Set-top Gateway (DSG) technology. With this qualification, the C4 CMTS, configured with the higher density 2Dx12U CAM provided the most reliable and scalable C4 CMTS solution available. The C4 CMTS supports DOCSIS Set-Top Gateway (DSG), allowing operators to transition the signaling, provisioning, and control of advanced settop boxes from proprietary to standards-based protocols. This transition of

C4/C4c CMTS Rel. 8.0.7

NOTE NOTE: these call capacities assume that the C4 CMTS is equipped with GNAMs. If the chassis is equipped with Ethernet NAMs, the number of MTAs supported is only 10,000. Dynamic Load Balancing

The Dynamic Load Balancing feature automatically moves modems from one upstream channel to another, or from one downstream to another (including from one 2Dx12U CAM to another). Requires 2Dx12U CAMs.

Legal Intercept

Legal Intercept provides the MSOs a mechanism for meeting legal requirements to intercept all IP data and voice traffic originated or sent to subscribers on the cable network. Legal Intercept is based on Cisco’s implementation described in RFC 3924. The C4 CMTS interprets SNMP SET/GETs to enable/clear/display subscriber taps and send intercepted packets to the Mediation Device.

PIM-SSM

PIM-SSM (Source Specific Multicast) provides the capability to request multicast traffic from a single source and build a source path tree (SPT) from the edge router back to the source of the multicast stream. It also contains requirements to provide SSM multicast data plane counts.

IGMP ACLs

IGMP ACLs provide the ability to limit what multicast groups can be joined on an interface by using a standard ACL to indicate what groups are allowed to be joined.

Secure NTP

A mechanism is provided for authentication of NTP messages. For MSOs who require NTPv4 functionality, including server or peer authorization, the C4 CMTS will only support the NTPv4 symmetric key MD5 secure hash authentication method.

DHCP Text Injection

DHCP Text Injection will allow the operator to distinguish which upstream channels DHCP packets originated from as they are forwarded to the DHCP server. The upstream will be identified in the circuit ID sub-option of the DHCP relay agent option (option 82).

Named Access List

By allowing the use of a description name to identify an access list rather than a number, full modification to an existing access-list (e.g., delete, append and insert new entries) by using the ACL name is now available. Also, we are adding the ability to allow multiple remarks per access-list entry.

Additional Modem States

One additional cable modem state indicating the status of the Network Access Control for a registered CM has been added. The CM’s Network Access Control state is provided via the modem configuration file. This variable indicates whether or not CPE devices are allowed to access the network through the CM even though the CM is registered.

4 C4 CMTS Features

C4/C4c CMTS Rel. 8.0.7

Integrated Upstream Agility

This provides the ability to enable or disable an Upstream Agility state machine for an upstream channel. The state machine includes permissible upstream channel frequencies and operating characteristics (e.g., channel width, modulation profile) along with rules to change from one operating characteristic to another.

Clear Cable Host/Modem

Enabled the ability to remove cable modems and CPEs from the system including removing them from the MACDB and C4 CMTS MIB tables.

ARP Throttling

Provides the ability to control the number of ARPS and ICMP packets that are generated due to traffic transmitted to IP addresses that do not have a valid (active or inactive) entry in the ARP cache.

Configure Cable Modem Vendor OUI

This feature provides the ability to configure a cable modem vendor name with the vendor’s Organizational Unique Identifier (OUI). The OUI is the first three bytes of the six byte CM MAC address.

Show Cable Modem Column

This new command will now allow you to create your own output by specifying exactly which columns you wish to see, thus maximizing your screen space and run-time.

Release 5.1.x Features

The following is a list of the new features included in Software Release 5.1.x: •

FlexPath™ DOCSIS 3.0-based Channel Bonding Enhancements

•

Enhanced Query Modem Counts on a per Upstream Basis

•

4 C4 CMTS Features

C4/C4c CMTS Rel. 8.0.7

DOCSIS Set-top Gateway (DSG) Configuration Simplification performs the automatic insertion of static multicast group memberships and the automatic insertion of multicast MAC/IP bindings when configuring DSG tunnels. Source IP Configuration for CM Remote Query allows the user to configure the IP address used for remote SNMP to get queries to any valid C4 IP address. DHCP Lease Query Feature Configurability adds a source IP address verification phase to the IP address learning process of the C4 CMTS. This configurable Cable Source Verify feature is intended to eliminate hostinitiated corruption of the layer 2 and layer 3 address spaces on the cable network. Automatic Gain Control uses an improved downstream power calibration algorithm on the 2Dx12U in order to maintain accurate downstream power levels in environments subject to fluctuating temperatures. NOTE QAM128 and Trellis Code Modulation (TCM) are not supported in Release 5.1. SCDMA is supported.

tions and allows the 24 upstream receivers to be shared across the eight available F-connectors. The 2Dx12U CAM is not supported in Rel. 8.0. Any F-connector can have between zero and 12 receivers assigned. The sum total of the receivers assigned to the even-numbered F-connectors (0,2,4,6) cannot exceed 12, and the sum total of the receivers assigned to the odd-numbered F-connectors (1,3,5,7) cannot exceed 12. Also, upstreams 0 to 11 must be on even-numbered connectors, and upstreams 12 to 23 must be on odd-numbered connectors. Some other features of the 24U CAM with Release 8.0 include: -

Up to 6,600 total subscriber devices per CAM Up to 9+1 hitless RF sparing All 24 channels support bonding (up to four channels per bonding group)

IS-IS Multi-topology (MT) provides independent topologies for IS-IS routing and is particularly useful when IS-IS is being used both for IPv4 routing and for migration to IPv6 routing. In this software release, the C4 CMTS supports MT #0 (IPv4 unicast) and MT #2 (IPv6 unicast) as described in RFC 5120. TFTP Enforce for IPv6-addressed Cable Modems provides modem security for devices addressed via IPv6, identical to the existing C4 CMTS functionality for IPv4 modems. The intent of this feature is to reduce or prevent occurrences in which an IPv6-addressed modem has an incorrect or modified configuration file. Fully Qualified Domain Name (FQDN) Support for IGMP Static Joins allows the IGMP join command in the C4 CLI to accept an FQDN as the IP multicast source address, instead of requiring an IP multicast address. The DNS must then contain the FQDN to IP address entry so that the CMTS can obtain the corresponding IP address from the FQDN parameter. Should the source IP multicast address have to change, the MSO would change it on the DNS and the C4 CMTS will then resolve the new address via DNS and re-initiate IGMP joins as needed. Multicast CAC for IP Video (Phase 1) extends the existing voiceoriented Connection Admission Control function to multicast service flows (intended for IP Video applications). Independent CAC control is provided for multicast flows, and parameters for reserving bandwidth for multicast and for limiting the total bandwidth utilized by multicast are included. Enhanced Processor Monitoring reports the utilization levels of the various microprocessors within the C4 CMTS modules (the control plane). There is a new SNMP notification as part of the processor monitoring feature that will send traps when the overload status of a card or the system changes.

Figure 5-1 illustrates the front view of the C4 CMTS. There are a total of twenty-one slots for modules. There are four main types of modules used to equip the slots in the front. These are sometimes referred to as front cards. Smaller modules, called Physical Interface Cards, or PICs, are inserted in each slot from the rear of the chassis. The PICs provide physical connectors for terminating cable. Between the front and back slots is the midplane of the chassis. Three C4 CMTS chassis can be mounted in a single 19-inch wide, seven-foot standard rack.

Network Diagram A cable network system consists of cable modems (CMs) at subscriber premises, a C4 CMTS at the cable plant operations area, a data-over-cable management software suite integrated with the operator's other management systems, and the Hybrid Fiber Coaxial (HFC) cabling that connects it all. DOCSIS defines the standard for communication among these elements. The C4 CMTS provides data switching functions as well as the radio frequency (RF) interface to and from the cable plant. It also provides ethernet interfaces to the Internet Service Provider(s). The data-over-cable management system provides both the end-to-end network management solution and the support for subscriber provisioning. Figure 5-2 shows a typical cable network architecture.

The Shuffle network spreads upstream channels across multiple PHY chips as the MSO populates the RF connectors in order from top to bottom. When fewer than eight F-connectors are wired (e.g. connectors 0 through 3), the shuffle network will enable the operator to access all 24 upstreams. The 24U CAM will support 24 upstream channels using eight connectors through the current 12U PIC. With the Shuffle network, connectors 0, 2, 4, 6 are connected to the first chip (upstream receivers 0 through 11) and connectors 1, 3, 5, 7 will be

Rules and Restrictions for 12U/24U CAM Configuration Before growing and configuring a 12U/24U CAM with its upstreams, you should review the following rules and restrictions. Slot Provisioning

Annex Upstream (US) Channel to Physical Connector Mapping

The 12U CAM must be grown in a CAM slot provisioned for a 12U CAM and the 24U CAM must be grown in a CAM slot provisioned for a 24U CAM. CAM sparing can only be done by like cards: a 12U can spare only for a group consisting of 12Us and a 24U can spare only for a group consisting of 24Us. All the CAMs in a sparing group must be of the same type. The CMTS supports multiple annexes in one system. See Mixed Annex

Support on page 9-23.

Guidelines for mapping upstream channels to physical connectors: •

There must be no frequency overlap among the upstream channels using the same connector.

•

The CMTS displays the following error message when the user attempts to change an upstream power level or channel width to a value that is not valid for that power level group: Upstream channel power level conflict with another channel using the same connector. If you receive the above message, the power level and channel width will remain unchanged.

The following guidelines are specific to the 12U CAM: •

There are 8 physical connectors and 12 upstream channels on the 12U CAM. If all channels are enabled then at least one physical connector will receive more than one upstream channel.

•

Any upstream or all of the upstreams can be connected to any one of the physical upstream connectors.

The following guidelines are specific to the 24U CAM:

Issue 2.0

•

There are 8 physical connectors and 24 upstream channels on the 24U CAM. When all upstreams are active, at least two connectors will be in use.

•

Upstream channels 0-11 are connected to connectors 0, 2, 4 and 6 while upstream channels 12-23 are connected to connectors 1, 3, 5 and 7.

•

Upstream channels connected to a single physical connector may vary in channel width and power levels as long as the variance falls within a user-configured power level group. The tables (Tables 10-7 through

Before Changing the Receive Power Level Settings of the 24U CAM If there are multiple upstream channels on a single 24U CAM connector and the user is trying to change the receive power level setting on one or more US channels and the new setting causes a change in the power level group (see Tables above), then the user must complete the following steps: 1 Unassign (decouple) the corresponding connector (for all upstream channels that are on that connector). 2 Set the receive power level for all upstream channels on that connector. 3 Add the connector back for all upstream channels on that connector. End of procedure

NOTE The above procedure will not apply when the user changes receive power level setting on one or more upstream channels on the same connector and the new setting does not cause a change in the amplifier attenuation settings. That is, the new and old receive power level settings occur within the same amplifier attenuation setting (per the tables listed in the 24U CAM Upstream Power Level Groups on page 10-14). The following is an example of setting the upstream channels receive power level (attenuation) that will cause a change in the amplifier attenuation settings. Upstream channels 3/0 and 3/1 have the following initial power and channel width settings (3.2 and 6.4 MHz and power level 0):

Measuring SNR in the 12U/24U CAM For the upstream channel Signal-to-Noise Ratio (SNR) in the C4 CMTS, there are two types of SNR: Channel SNR and Modem SNR. Channel SNR is calculated on a upstream channel basis and the per Modem SNR is calculated from the primary upstream service flow (primary SID) of the modem. TDMA and SCDMA Long Term Slicer Error Power is also used for calculation of the logical channel SNR. If the current Channel SNR is 0 (no traffic on the upstream), the SNR algorithm uses Long Term SNR calculation based from PHY Slicer error which is based upon all IUC’s including contention IUCs (i.e. 1 and 3). Two pieces of information are used in calculating SNR: symbol errors and burst counts. The SNR calculation is performed once the burst count is greater than a certain threshold. The threshold varies depending on whether it is the initial ranging period or during data traffic.

The SNR reading is 0.0dB when:

Channel SNR Calculations

•

The logical upstream channel is not in service (IS state) or

•

No modem is registered on the upstream channel

In normal operations, SNR readings reflect upstream channel conditions. The SNR readings will decrease as noise level goes up. In an ideal condition, when noise is not present or very low, the SNR value in decibels is in the high 30’s. Two SNR calculations are performed in the CAM for Channel SNR. SNR based from MAC (IUC4 plus all data IUCs) does not include contention Interval Usage Codes (IUCs) such as 1 and 3. The second SNR calculation is based on all IUCs including IUC1 and IUC3. The two SNR values can be obtained with show cable noise cable-upstream slot/uport detail CLI command. The show cable noise CLI command outputs only the SNR without the contention IUCs. The channel SNR calculation is the same between the 12U and 24U CAM. The SNR is based on the MAC (IUC4 + all data IUCs) excluding contention IUC1 and IUC3. A burst count threshold of 100 packets is used in the calculation and the MIB attribute for this SNR is docsIfSigQSignalNoise.

Modulation Profiles The pre-defined modulation profiles discussed in this section are used as a means to define the values of the several parameters needed to configure an upstream (US) channel. These modulation profiles are each given an ID number. They can be modified or used as a starting point to create other modulation profiles for upstream channel definitions that better suit the customers’ applications and environments. Default Modulation Profile

The Modulation Profile ID 2 uses QPSK and TDMA, and it is the default profile. The following sections show you how to define a new modulation profile. NOTE Modulation profile ID 2 can be modified but it cannot be deleted.

Procedure 10-2

How to Create and Apply a Modulation Profile to an US Port This procedure can be used to modify existing modulation profiles or to add new ones. Modulation profiles must be created and then associated with specified upstream ports. Table 10-17: Existing or New Modulation Profile IF YOU SPECIFY AN

Procedure 10-3

How to Configure an Upstream (US) Channel Perform this procedure for US channel 0 and repeat as necessary for all channels on this CAM. The valid range for US channels is 0–11 (12U CAM) or 0-23 (24U CAM). Some steps are optional. By not executing the optional steps, default settings are applied.

Valid Center Frequencies

In the first step, set the center frequency of the upstream channel. The range of valid center frequencies varies according to the channel width selected. The overall upstream bandwidth in North America is from 5–65 MHz. The first valid center frequency in Hertz is 5,000,000 plus ½ of the channel width. The last valid frequency is 65,000,000 minus ½ of the channel width. Thus, 5-65 MHz is the overall upstream range. To calculate valid upstream center frequencies, refer to Table 10-18 below.

2 If desired, set US channel width in Hertz (default = 3200000): configure interface cable-upstream / cable channel-width {200000 | 400000 | 800000 | 1600000 | 3200000 | 6400000} Where 1600000, 3200000, and 6400000 represent the valid values for channel bandwidth in Hz. Setting the Rx Power Levels

The default receive power level of the CMTS is 0 dBmV. 1 If desired, change the input Rx power to any level from -10 to 26 dBmV (default = 0 dBmV). As shown in Table 10-19, the valid range varies according to the upstream bandwidth. configure interface cable-upstream / cable power-level If the width of a channel is changed and the receive power level is no longer valid, the CMTS automatically adjusts the receive power to the nearest valid value.

a. Setting power levels above 23dBmV is not recommended.

NOTE Resetting the receive power level in a single step from minimum to maximum in a given power range may prevent CM range requests from being received. For example, if the US channel bandwidth is 3200000 Hz and the power level is reset from -10 to 26 dBmV, then the CMs might not register. The CMTS avoids this by resetting the power in one or more steps according to the max-power-adj parameter found in the CMTS cable upstream provisioning. Refer to the tables in 24U CAM Upstream Power Level Groups, page 10-14, to make sure your settings fall within the proper table.

Explanation of Upstream Parameters Modulation profiles are pre-defined sets of upstream channel parameters which make it easier to configure or reconfigure upstream channels. This document describes the parameters used in modulation profiles. Where possible, it lists the default values of these parameters. For greater technical detail on these parameters and their functions, see the DOCSIS Radio Frequency Interface Specification. In order to understand all of the parameters used in modulation profiles, some terms must be defined: IE — Information Element — portions of the allocation MAP used to define transmission opportunities for cable modems. Each IE is a 32-bit quantity, of which the most significant 14 bits represent the Service ID (SID), the middle 4 bits represent the Interval Usage Code (IUC), and the low-order 14 bits represent the minislot offset. SID — Service ID. SIDs are assigned to upstream Service Flows. The CMTS allocates upstream bandwidth to SIDs, therefore to the cable modems served by the SIDs. SIDs are also used in Quality of Service functions. Certain values of SIDs are defined in the RFI specification and convey specific meanings for the service flows they represent: •

0x3FFF implies all CMs (broadcast)

•

0x3FFx where x is a value of 0x1 to 0xE used to indicate that a data message must fit in x number of minislots. This can only be used in the Request/Data IE (broadcast).

•

0x3Exx This can only be used in the Request IE to allow different priorities to use the request region (broadcast). If If If If If If If If

Table 10-21: Modulation Profile Parameters Parameter ID

Description Identifier. The number of the modulation profile. The CMTS supports a range of up to two billion modulation profile IDs.

Interval Usage Code. The IUC typically has an assigned numeric value. It defines what kind of Information Element (IE) is being sent from the CMTS to the cable modems: • • • • • •

1 Request This portion of the upstream map interval is used by cable modems to request bandwidth for data transmission. If the class of the SID associated with the request IE is broadcast, then cable modems must contend with each other for upstream bandwidth. If the class of the SID associated with the request IE is unicast, then this is an opportunity for a single cable modem to request additional bandwidth. 2 Request/Data Either data requests or short data messages can be sent in this portion of the upstream map interval. A multicast SID must be used to indicate the size of the data message that can be sent. This IE is not used by the CMTS map algorithm and as such changes made to this IE will have no affect on upstream data transmissions.

IUC

3 Initial Ranging (Also called Initial Maintenance). This IE allows cable modems a method to adjust their timing, frequency, and transmit power so that they can reliably communicate with the CMTS. The timing adjustments allow for the round trip delay of the fiber optic/coax plant plus the time to transmit the range request message. A DOCSIS 1.X cable modem can send a range request message only during this IE. A DOCSIS 2.0 cable modem can send a range request message or an initial range request message depending upon the type of the upstream channel. Normally, range request messages are sent in this IE when it contains a broadcast SID, meaning cable modems must contend with each other when transmitting. An initial range request message can be sent either with a broadcast SID or with a unicast SID depending upon the situation. 4 Periodic Ranging (Also called Station Maintenance). This IE is used so that cable modems can perform station maintenance. This IE is unicast. Only the range request message — no other data — can be sent in this IE. 5 Short Data Grants This unicast IE gives permission to a specific cable modem to transmit one or more Protocol Data Units (PDUs). The cable modem uses this region in the upstream map interval if the number of minislots required to send the message is less than or equal to the maximum burst interval specified for a short data grant in the Upstream Channel Descriptor (UCD) message. The reason that grants can be split into short and long data grants is for the sake of FEC encoding. Short data grants are used only when a cable modem is transmitting via an upstream channel that is compatible with DOCSIS 1.X. 6 Long Data Grants This unicast IE gives permission to a specific cable modem to transmit one or more PDUs. The cable modem uses this region in the upstream map interval if the number of minislots required to send the message is greater than the maximum burst interval for a short data grant in the Upstream Channel Descriptor (UCD) message. The reason that grants can be split into short and long data grants is for the sake of FEC encoding. Long data grants are used only when a cable modem is transmitting via an upstream channel that is compatible with DOCSIS 1.X.

Differential Encoding True = enabled; False = disabled.

fec-tbytes

Forward Error Correction (T) The number of bytes with errors that can be corrected with FEC in the size specified in the codeword information byte length. A value of zero indicates that FEC is disabled. For each byte that can be corrected there are two additional FEC parity bytes that are added to the FEC codeword. The FEC codeword contains both the FEC information bytes and the FEC parity bytes. The number of codeword parity bytes is 2xT, where T = 0-10 for a DOCSIS 1.x upstream channel and 0-16 for a DOCSIS 2.0 upstream channel.

fec-len

Forward Error Correction, Length of Codeword (K) The number of bytes in the information bytes of the FEC codeword. Assuming that FEC is enabled, the FEC codeword can contain from 16 to 253 information bytes. The FEC codeword contains both the FEC information bytes and the FEC parity bytes and can be between 18 and 255 bytes. A shorter codeword will increase the amount of overhead but allow for more errors to be corrected in the total data frame. Preamble Length The preamble serves to put the FEC and randomizer (also called the scrambler) into known states before the data is transmitted. The preamble also helps the receiver to receive an upstream burst accurately. DOCSIS 1.X (type 4 TLV in the UCD) requires the preamble length to be between 0 and 1024 bits.

• For a TDMA or tdma-atdma upstream channel, IUCs of 3 and 4 with 16 QAM must have a preamble length in the range of 200 to 768. • All other cases for IUCs of 3 and 4 must have a preamble length in the range of 100 to 768. • For a TDMA or tdma-atdma upstream channel, IUCs of 1, 5 and 6 with 16 QAM must have a preamble length in the range of 80 to 256. • All other cases for IUCs of 1, 5 and 6 must have a preamble length in the range of 40 to 256. • For IUCs 9, 10 and 11, the preamble length must be in the range of 40 to 512. Note: Even with the above guidelines, it is possible to choose parameters such that the Preamble Superstring which contains the preamble strings for all the different IUCs does not fit within either the 1024 or the 1536 bit limits. Contact technical support for further assistance if experiencing these problems.

seed

10-34

The 15-bit seed value for the scrambler polynomial. The pseudo-random generator (randomizer) is used so that the data stream will not produce a long string of either 1's or 0's. Changing the seed for the pseudo-random generator will cause the generator to produce a different pattern of ones and zeroes if the same input data is sent to the pseudorandom generator. Some seeds will work better than others for producing a good distribution of 1's and 0's without a contiguous string of either 1's or 0's. The range of possible values is from 0-32767.

Description

burst-len

Burst length The maximum number of minislots that can be used by the IE. For both short data and advanced PHY short data grant IEs, this field must be present and must contain a non-zero value. In general, a zero value implies that the IE is not limited. Range = 0–255.

guard-time-size

Guard Time This is the amount of time measured in symbols that must exist between successive frames. By definition SCDMA channels have no additional time between frames; consequently, this parameter cannot be used for SCDMA. This field is required for non-SCDMA channels and according to the RFI specification must contain a value of at least 5 symbols. This value may be derivable from other network and architectural parameters. Range = 8–96 symbols.

last-cw

Last Codeword This indicates whether the last FEC codeword is of a fixed length or shortened. True = shortened; False = fixed length.

scrambler

This field indicates whether the scrambler or randomizer is enabled or not. True = enabled; False = disabled.

int-depth

ATDMA Byte Interleaver Depth This parameter must be present for all IUCs with an ATDMA upstream channel or IUCs 9, 10 and 11 with a tdma-atdma upstream channel. For all other cases, this parameter must not be present. There are three different states for the ATDMA Byte Interleaver signified by the values: 0 = dynamic mode, 1 = off, 2floor(2048/(K + 2T)) = fixed mode. In fixed mode, there is one FEC codeword per row and the depth is the number of rows in the interleaving matrix. In dynamic mode, the system chooses the row and column sizes of the interleaving matrix to obtain optimum burst noise robustness.

int-blocksize

ATDMA Byte Interleaver Block Size This parameter must be present for all IUCs with an ATDMA upstream channel or IUCs 9, 10 and 11 with a tdma-atdma upstream channel. For all other cases, this parameter must not be present. This parameter represents the number of bytes that can be used by the ATDMA interleaver when in the dynamic mode of operation. Range = 2*(K+2T) – 2048. To obtain optimum benefit of the ATDMA interleaver, use a value of 2048.

pre-type

Preamble Type For DOCSIS 2.0 upstream channels, there are two possible constellation patterns that can be used for the QPSK preamble: qpsk0 and qpsk1. With qpsk1 the preamble’s constellation is at a higher power level when compared to qpsk0. DOCSIS 1.x channels must use the qpsk0 constellation pattern.

tcm

Trellis Coded Modulation TCM must only be used with an SCDMA upstream channel. TCM causes one bit in the symbol to be used for encoding purposes. This bit acts like a parity bit for decoding the rest of the bits in the symbol. Since one bit is removed from the symbol for encoding purposes, the data throughput is similar to what is received if the next lower value for the modulation type is used. The values for the TCM are either on or off.

int-stepsize

SCDMA Interleaver Step Size In an SCDMA upstream channel, interleaving is performed on a sub-frame basis. The interleaver step size determines the manner in which symbols are interleaved within the sub-frame. This option must be present for a SCDMA channel and must not be present for all other upstream channel types. Range = 1–31.

spreader

SCDMA Spreader In an SCDMA upstream channel, there are two modes of spreader operation: on and off. According to the RFI specification, IUC 3 must use spreader off, and IUCs 1, 9, 10 and 11 must use spreader on. And IUC 4 can use either on or off. However, the CMTS only supports the usage of spreader off for IUC 4. This option must be present for an SCDMA channel and must not be present for all other upstream channel types.

subframe-code

SCDMA Codes per Sub-Frame In an SCDMA upstream channel, interleaving is performed on a sub-frame basis. The codes per sub-frame define the size of the sub-frame. A sub-frame can vary in size from 1 code up to the total number of active codes. This option must be present for an SCDMA channel and must not be present for all other upstream channel types. Upstream DOCSIS-Mode This parameter contains the type of the upstream channel which must correspond to one of the following values:

According to the DOCSIS RFI Specification, another value that is typically associated with upstream modulation profiles is the preamble offset start value. It indicates where in the possible string of the preamble bits the actual preamble actually starts. This value is determined by the CMTS. The string of possible preamble bits is included in the UCD message. Once you have equipped the CMTS with CAMs and put them in service, the upstream channels have to be configured. Use the following command to choose the desired modulation profile and other parameters that determine the upstream channel’s characteristics: configure interface cable-upstream cable where parameter is replaced by one of the parameters listed in Table 10-22, Parameters Used in Configure Interface Cable Upstream (Channel) Command, on page 10-37. NOTE Logical channels are sometimes called subinterfaces. When changing the following upstream parameters, if no logical channel (n.0) is specified, then the command syntax assumes logical channel 0. • Modulation profile ID • Ranging backoff range • Data backoff range • Map size (in 800 microsecond ticks) • Slot size (in 6.25 microsecond ticks) • SCDMA active codes • SCDMA frame size • SCDMA hopping seed • SCDMA codes per slot For all other upstream parameters, if you do not specify a logical channel, then the CLI code will apply the change to the physical interface. In other words, both logical channels of the upstream will be affected. For example, the following command does not specify a logical channel, and it affects the entire upstream: configure interface cable-upstream 5/0 no shutdown The following command brings up only logical channel 0: configure interface cable-upstream 5/0.0 no shutdown

Notes on DOCSIS 3.0 Upstream Frequency Range

DOCSIS 3.0 (North America) provides for an extended upstream frequency range of 42 – 85 MHz. The 12U CAM supports an upstream range of 5 – 65 MHz: it is limited by hardware constraints to a maximum of 65 MHz. The 24U CAM hardware has been designed to support a range of 5-85 MHz, but currently the software will only support a range of 5-65 MHz. Use the following command to set the maximum upstream frequency for all channels (global) within the chassis: configure cable freq-us-max {42 | 55 | 65} [no] The default maximum upstream frequency for global Annex A is 65 MHz; for Annex B it is 42. The maximum upstream frequency of 55 MHz must be explicitly set. The no parameter sets the upstream frequency range to the default value specified by the current Annex.

Modulation Profiles: Default and User-defined In the CMTS there is a default modulation profile that is automatically created for the user: modulation profile 2. Modulation profile 1 supported a previous version of the upstream CAM and is no longer available. CMTS users are free to create user-defined modulation profiles. User-defined modulation profiles provide a shortcut method for a user to easily create modulation profiles just by specifying the desired channel type and modulation rate. User-defined modulation profiles can be assigned to any number from 3–n to create a new profile. (It is recommended that you do not use 2; otherwise you will overwrite the default). If you choose a number that is already in use, then the existing modulation profile will be overwritten by the new one. There is almost no limit to the number you can create. Each user-defined modulation profile is defined by a channel type, such as tdma, and a modulation type, such as 16QAM. The user-defined profile defines most of the parameters for that modulation and channel type. For example, if you want to use the user-defined profile for TDMA and 16QAM to create modulation profile 20, enter the following command: configure cable modulation-profile 20 tdma qam-16 Modulation profile 20 as defined by the above command: Interval Chan Mod Pre Dif FEC FEC Scr Max Guar L Scr ---Atdma--- Prea -----Scdma----Usage Type Type Len Enc CW amb Bur Time C amb Int Int mble TCM Int Sp Sub Code En Len Seed Siz Size S En Depth Block Type En Size En Cod --------------------------------------------------------------------------------------------1 request tdma qpsk 56 F 0 16 338 0 8 F T - 3 initial tdma qpsk 640 F 5 34 338 0 48 F T - 4 station tdma qpsk 384 F 5 34 338 0 48 F T - 5 short tdma q16 168 F 6 78 338 23 8 T T - 6 long tdma q16 192 F 8 220 338 0 8 T T - -

Basically, user-defined modulation profiles allow the user to specify the channel type and the modulation rate for the data IUCs and the rest of the information for the modulation profile is filled in with recommended values. These recommended values are generic values that should work across a wide variety of plants. Users may want to optimize these values to the specific needs of their cable plant.

Optimizing a Modulation Profile This section is meant to serve as a guide to some of the issues that are involved in optimizing a modulation profile. Optimizing a modulation profile involves many factors; this document does not claim to explain them all. What you are really trying to do is to optimize throughput in the upstream channel connected to the CMTS and still maintain an acceptable packet error rate. This distinction is important because noise on the upstream channel plays a big role in determining the best modulation profile to use. Additionally, noise on an upstream channel is not consistent over time. Because of this if a single modulation profile is used, then this modulation profile must be able to handle the worst case noise that is expected on the upstream channel and still achieve a reasonable level of performance.

Noise and SNR versus Modulation Symbol Rate Unfortunately, different types of noise are typically seen on an upstream channel, and each type has a different effect on the upstream channel. There is the Average White Gaussian Noise (AWGN) that is always present and is typically referred to as the noise floor. There may be impulse and ingress noise, both of which may cause the noise floor to spike. NOTE Impulse noise is a spike in the time domain and ingress noise results in a spike in the frequency domain. There are various techniques that can be used to reduce the effects of each of these types of noise. For example, having all the cable modems transmit at a higher power level (assuming there is enough power headroom) gives a better Signal to Noise Ratio (SNR) because the modem’s bursts are at a higher power level while the AWGN remains at about the same level. Forward Error Correction (FEC), Ingress Cancellation Block (ICB), and interleaving can be used to correct ingress and impulse noise. Noise affects the SNR. The SNR is the primary indicator of what modulation rate can be used on the upstream channel. If one assumes that an upstream channel has no ingress or impulse noise, then theoretically the following modulation rates would work as long as the SNR of the upstream channel is higher than the stated threshold shown in Table 10-23. Table 10-23 is based on theory. In the real world the thresholds shown here would be too low. The amount of margin that needs to be added is dependant upon the types of noise present in the plant and how that noise

varies over time. Even in a clean plant, we would recommend a margin of at least 4 dB. For a plant with a high noise level, the margin should be increased. Additionally, the CMTS is effective in eliminating AWGN, less effective for impulse noise, and still less effective for ingress noise. Therefore, the amount of SNR margin may also be varied depending upon the type of noise that is present in the system. Table 10-23: Minimum SNR Thresholds under Lab Conditions

Forward Error Correction (FEC) can correct errors that occur in the upstream channel; however, this comes with a cost of additional overhead. FEC is typically expressed in terms of two parameters, T and k. T is used to represent the number of byte errors that can be corrected. The k parameter is used to specify the number of bytes over which the T number of byte errors can be corrected and is called the codeword length. The cost of correcting up to T byte errors in k data bytes is that there is an additional 2 * T bytes of overhead. Note, the values for T are shown in the FEC column in the show cable modulation-profile CLI command. The values for k are shown in the FEC CW Len column in the show cable modulation-profile CLI command. show cable modulation-profile 6 Typical output:

Figure 10-4: Relation of FEC Codewords to Data Packet A slight decrease in SNR can cause a large increase in the Packet Error Rate (PER). There comes a point where simply adding additional FEC to attempt to correct for the upstream errors is no longer efficient. Once this point is reached, it is more efficient to use a lower modulation rate with less FEC overhead than to continue to increase the FEC protection. Figure 10-5, obtained using the ICO tool, illustrates that it can be more efficient to use a lower FEC setting and a lesser modulation rate. Ideally the channel will operate as far towards the upper left of this chart as possible. The Shannon curve displays what is theoretically possible. The curves for the different modulation rates show the effect of increasing the value of T for the FEC for each of the different modulation rates for the specified modulation profile parameters. In this case, the default 64 QAM ATDMA modulation profile was used. Because the lab chassis used to obtain the data in Figure 10-5 was provisioned with a very short cable plant, these numbers approach the theoretical values listed above for SNR. They do not reflect real-world noise levels. In the 64 QAM modulation profile, if the SNR of the plant is about 20 dB, then a high T value is required to limit the Packet Error Rate (PER) to 0.1%. The highest bit rate one can achieve is about 8 Mbps. However, if we reduce the modulation to 32 QAM and decrease the FEC T value, the bit rate goes up to 12 Mbps under the same conditions. For practical reasons the minimum value of k must be at least 16. Because of this, if there are not 16 data bytes either to be sent or remaining to be sent, then the modem must pad out this data to be 16 bytes. This especially comes into play for IUC 1 where the request frame is 6 bytes. Therefore, to have even the minimal values for FEC of T = 1 and k = 16 for IUC

1, would mean that there must be 18 total bytes (k + 2T) required to transmit 6 bytes of data. Given this amount of overhead, it is normally better to use a low order of modulation such as QPSK and no FEC for IUC 1, assuming the noise on the plant allows this to work.

For example, assuming there is a lot of ACKs and small packets (i.e. 64-byte packets), then the FEC codeword length should be set so that there is no need to pad out the remaining 16 bytes. Assuming a 6-byte MAC header, it would take 70 bytes to send the 64-byte packet. Also assuming BPI is enabled then there is an additional 5-byte extended header such that it would take 75 bytes to send a 64-byte packet. Note, that the preamble is not included in FEC and should not be included in these calculations. In general, the predominant packet size

plus the associated overhead determines that the k value should not be a value between 1 and 15; otherwise there is additional overhead in padding of the codeword. In the case of a DOCSIS 2.0 upstream, the modulation profile will include an IUC 11. The IUC 11 is used for UGS data flows. The thing that most commonly uses UGS data flows is VoIP. There are several different codecs that are used in the industry; however, typically there is only one codec with one sampling period (5, 10 or 20 milliseconds) on a given cable plant. This tends to cause all of the upstream UGS data packets to be of the same size. Knowing the size of these UGS data packets, the value of k for the FEC should be such that no additional padding is required for FEC. Preamble Lengths

The preamble length is something that is displayed in the show cable modulation-profile CLI command in the Pre Len column. This value represents the number of bits that are in the preamble. In general the preamble is transmitted as a QPSK symbol no matter what the modulation type for the IUC actually is. One exception to this is that a 16 QAM TDMA upstream channel will use 16 QAM symbols or 4 bits per symbol. The preamble length is used by the upstream receiver to decode the upstream burst even if the upstream burst is not perfectly aligned with the proper spot in the upstream spectrum. The preamble helps to recognize where an upstream burst actually begins, and is also used to perform equalization on the upstream burst, provided that the preamble is long enough. In general a longer preamble is desired for IUC 3, Initial Ranging, since this is the first time that the CMTS has heard from this modem. Additionally, the extra equalization also helps in IUC3. The amount of gain for equalization does not normally warrant the additional overhead in terms of length of the preamble especially in IUCs other than the ranging IUCs (IUCs 3 and 4). The point where the PHY chip switches from simply recognizing the start of the preamble and making sure that it has the correct pattern to recognizing when extra symbols are used for equalization depends upon several parameters. Some of these parameters are not currently configurable and require very detailed knowledge of how the PHY chip operates. As such, this paper will not explain all of the details behind the following numbers. The point where equalization begins for preambles using QPSK on IUCs 3 and 4 is currently after 136 bits. For IUCs 3 and 4 when 16 QAM is used, equalization begins after 272 bits. For non-ranging IUCs (any IUC except IUCs 3 and 4) for preambles using QPSK, equalization begins after 132 bits. For non-ranging IUCs (any IUC except 3 and 4) for preambles using 16 QAM, equalization begins after 264 bits.

10 Upstream Cable Access Modules (UCAMs)

If there is a lot of impulse noise in the upstream channel, then it is probably worth using shorter preambles to lower the probability that an impulse will actually hit a preamble. Note that if an impulse actually hits a preamble that most likely the entire frame will be discarded because of a bad preamble. Part of the reason behind this is that the preamble is not protected with FEC. As such with a lot of impulse noise on the upstream channel, the preamble lengths should be shortened. Because of the way that the PHY receiver works in the CMTS, for an SCDMA channel type, there is a slight benefit that can be gained if the preamble length is a multiple of the SCDMA frame size in symbols. The default value for the SCDMA frame size is sixteen symbols. Since the preamble for SCDMA is always QPSK, which is two bits per symbol, there is a slight benefit if the preamble is a multiple of 32. Differential Encoding

Differential encoding can be enabled since it is a feature in the DOCSIS RFI specifications; however, there is no real gain to be had in doing this. This mode is rarely used in the field; therefore we recommend that you leave Differential Encoding disabled. (For more information, see http://www.cablemodem.com/specifications.)

Scrambler Seeds

This is a value that tends to be tied to the PHY hardware. These values have already been optimized by the PHY manufacturer. Therefore, do not change the values that come with the default modulation profiles for the scrambler seed.

Maximum Burst Size

This value is contained is something that is displayed in the show cable modulation-profile CLI command in the Max(imum) Bur(st) Size column. This value is in terms of maximum number of minislots that may be used by the associated IUC. A value of 0 for the maximum burst size means that there is no limitation on the size at least in the modulation profile. NOTE The short data grant (IUC 5) and the advanced phy short data grant (IUC 9) must have non-zero values. It is important to understand the type of traffic that is to be sent upstream and the relative priority of that traffic when adjusting this parameter. For example, if there is VoIP traffic on an upstream that uses a TDMA channel type, then the VoIP traffic should be given a higher priority in terms of FEC protection. Assuming that there is more FEC associated with a short data grant (IUC 5) than with a long data grant (IUC 6), then the maximum burst size should be set such that the higher priority traffic, in this case VoIP, uses the IUC with the higher level of FEC protection.

C4/C4c CMTS Rel. 8.0.7

When the modulation profile is for an ATDMA or an SCDMA channel, the modulation profile will contain the UGS IUC 11. The VoIP traffic will tend to use this IUC on a DOCSIS 2.0 upstream channel. In this case make sure you do not include the UGS data packets into the process of determining the best value for the maximum burst size. Guard Time Size

The guard time size is given in the Guar Time Size column in the show cable modulation-profile CLI command. The guard time size is related to processing delays with a non-SCDMA upstream channel and is defined to be zero for an SCDMA upstream channel. The times for nonSCDMA channels are already optimized based upon the hardware to be as small as possible without losing data. If the numbers are increased, then upstream bandwidth is lost without any additional gains. Changing the default is not recommended.

Shortened Last Codeword

A codeword is specified by the k parameter for FEC. Assuming the data packet is not an even multiple of k, then the last codeword used to transmit a data packet will have less than k bytes to send. This parameter controls the format of that last codeword. The last codeword must always contain at least 16 bytes whether shortened or not. This parameter control whether or not the last codeword must contain k bytes or if it can contain between 16 and k bytes. If the last codeword can contain between 16 and k bytes, the last codeword is allowed to be shortened and this parameter has a values of true (T). If the last codeword must be padded out to contain k bytes, then the shortened last codeword value is set to false (F). The shortened last codeword is displayed in the LCS (Last Codeword Shortened) field in the show cable modulation-profile CLI command. In general having the shortened last codeword set to true will improve upstream efficiency in that there is less overhead associated with the additional padding in the last codeword. The default modulation profiles in general for IUCs 1, 3 and 4 do not have this set to true, simply because the messages sent on IUCs 1, 3 and 4 are of a fixed length and the values for k are already optimized for this length. As such there is no benefit to turning on shortened last codeword with the default modulation profiles unless the value of k is changed for these modulation profiles to a nonoptimal value.

Scrambler Enable

The scrambler enable is shown in the show cable modulation-profile CLI command in the Scramb En column. The scrambler might be better called a randomizer. Having this field set to true enables hardware that randomizes the bit stream to avoid a long pattern of either zeroes or ones. This helps in the overall transmission efficiency of the entire system. In general this should always be set to true (T).

ATDMA Interleaver Depth

With an ATDMA upstream channel, there is the capability of using an interleaver that is not available in the DOCSIS 1.X version of TDMA. This interleaver works on a byte basis. When enabled, the interleaver will change

10 Upstream Cable Access Modules (UCAMs)

the order in which bytes are transmitted. This has a side effect of causing additional latency in the upstream direction. The benefit is the additional protection against impulse noise. In general an impulse will corrupt some number of bytes that are transmitted consecutively with time. If the bytes are all from the same FEC codeword, and if FEC is not able to correct for this problem, then the data is lost. However, by ordering the transmission of bytes such that bytes from multiple FEC codewords are intermixed, the same impulse will hit fewer bytes from the same FEC codeword giving a better chance that FEC will be able to recover the corrupted data. The ATDMA interleaver depth is shown in the show cable modulationprofile CLI command in the Atdma Int Depth column. This value controls how this interleaver works. A value of 0, puts the interleaver into a dynamic mode such that the interleaver adjusts the way that it interleaves the data based upon the size of the data to transmit. A value of 1, turns off this interleaver. Any other value directly controls how many FEC codewords are interleaved together. When directly controlling how many FEC codewords are interleaved together, the value has a range from 2 to the floor (2048 / (k + 2T)) where k and T are the FEC parameters described in the FEC section of this document. The default modulation profiles use the dynamic mode of operation in order to get as much protection from impulse noise as possible. If a system has extremely tight restrictions in terms of upstream latency, then the amount of interleaving may be changed to either be off or of a lesser amount. This comes at the cost of reduced impulse noise immunity. ATDMA Interleaver Block Size

This is another control for the ATDMA byte interleaver and is shown in the show cable modulation-profile CLI command in the Atdma Int Block field. According to the DOCSIS 2.0 RFI specification, both the CMTS and a cable modem must contain 2048 bytes of memory to perform the ATDMA byte interleaving. This parameter controls how much of that memory is used. The parameter can vary from 2 * (k + 2T) up to 2048 where k and T are the FEC parameters described in the FEC section. When the ATDMA byte interleaver is in the dynamic mode of operation, this parameter should really be left at the 2048 value; otherwise, the byte interleaver will perform sub-optimally. Note, the dynamic mode of operation and a block size of 2048 are used in the default modulation profiles.

Preamble Type

Issue 2.0

An upstream channel using either ATDMA or SCDMA, has the capability to change the power level at which the preamble is transmitted. This is displayed in the show cable modulation-profile CLI command in the Preamble Type column. There are two different values that are possible for the preamble power levels. The first value is QPSK0 which corresponds to the transmit levels that are used by a DOCSIS 1.x upstream channel. The second value is QPSK1, which uses a higher power level. For actual differences in the power levels, see the DOCSIS 2.0 RFI specification.

ARRIS PROPRIETARY — All Rights Reserved

10-49

10 Upstream Cable Access Modules (UCAMs)

C4/C4c CMTS Rel. 8.0.7

By transmitting at a higher power level, there are times when a preamble of type QPSK1 will be heard when the QPSK0 preamble type would not be heard. Therefore QPSK1 is used for the default modulation profiles. SCDMA TCM Enable

SCDMA upstream channels can use Trellis Coded Modulation (TCM). The Scdma Tcm En column of the show cable modulation-profile command shows whether it is enabled. Theoretically there is a slight gain to be had by using TCM. However, in practice there are sometimes problems with TCM. There are cases where TCM will actually compound problems and cause more errors than it solves. Consequently, these issues tend to offset the possible gain. TCM is not enabled in the default modulation profiles.

SCDMA Interleaver Step Size

This parameter controls how the interleaver actually interleaves symbols in an SCDMA frame. It appears in the show cable modulationprofile command in the Scdma Int Size column. According to the DOCSIS RFI specification, this parameter has a value from 1 to 31. The PHY chip that is used places an additional restriction in the value must be at least 1 and has a maximum of SCDMA frame size minus 1. The SCDMA frame size is also called the SCDMA spreading interval. In general increasing this number will helps reduce impulse noise. The cost associated with increasing this value is additional latency. The default modulation profiles have a value of 5 for this parameter.

SCDMA Spreader Enable

According to the DOCSIS RFI specification, if SCDMA is enabled, IUC 3 must have the spreader off and the IUCs 1, 9, 10 and 11 must have the spreader on. This only leaves IUC 4. The specification states that it can have the spreader on or off. However, the current version of the software only supports spreader off for IUC 4. Therefore, all of the values for the spreader must remain the same as what is currently in the default modulation profiles. This is shown in the show cable modulation-profile command in the Scdma Sp En column.

SCDMA Codes Per Subframe

This parameter is used in with the SCDMA interleaver step size to determine how data is interleaved with SCDMA. This parameter is shown in the show cable modulation-profile command in the Scdma Sub Code column. When interleaving with SCDMA, preamble and TCM-encoded symbols are interleaved in one way and non-TCM-encoded symbols are interleaved in another. This parameter has the greatest effect on the preamble and TCMencoded symbols. Since in general TCM is not recommended, this simply leaves the preamble symbols. As such this parameter does not tend to have much effect on the overall performance of the system.

This chapter provides the basic procedure to bring up a C4 CMTS system for Release 8.x. This is not a software upgrade procedure: it assumes that the chassis is not yet in service. Installing the chassis, modules, and cards and configuring the system are addressed in this chapter. It is advisable to read through this information and become familiar with the order of operation before you begin. This chapter is based on a minimal configuration for a duplex system and bring-up. The minimal configuration and examples used in this chapter will consist of one System Control Module (SCM), one Router Control Module (RCM), one 24U Cable Access Module (CAM) and a 32D CAM. Most systems will be configured in redundant mode which means that each of the boards will have a spare or be part of a sparing group.

Before You Begin In order to properly set up the C4 CMTS for Release 8.0, several items are required to make the installation run smoothly. These include: 1 Chassis installation and powering

It is assumed that the C4 CMTS has been mounted in a rack in the headend and cabled for power prior to starting the Release 8.0 C4 CMTS installation. Do not power up the chassis until told to do so in the procedure. DC Power — For additional information on power on the system, refer to the C4 CMTS User Guide chapter on “Installing/Replacing Modules and Initial System Configuration.”

HFC Network Connectivity

A useful tool for planning the C4 CMTS configuration is the Network Connectivity Plan, as shown in Figure 11-1, page 11-3. This plan details the physical connections needed for the C4 CMTS to reach the HFC plant as well as how the C4 CMTS will be connected to the Operator Network for Internet Access and provisioning, monitoring, and control. Another useful tool for the C4 CMTS configuration is the HFC Network Connectivity Worksheets provided at the end of this chapter. These worksheets help with the channel and spectrum mapping tasks that are necessary for DOCSIS 3.0 deployments. This information is reflected in the C4 CMTS running configuration and is gathered to make that configuration complete. Blank worksheets for configuring your network connectivity plan are located at the end of this chapter.

11 Basic Bring-up Procedure

1. Install Cards, Rear PICs, Filler Panels, PCMs, and Fans

C4/C4c CMTS Rel. 8.0.7

The C4 CMTS chassis hardware is configured as follows: •

The chassis has 21 slots that can be filled with various modules

•

Slots are numbered from 0-20 counting from left to right

•

Slots 19 and 20 are reserved for SCMs

•

Slots 17 and 18 are reserved for RCMs

The 32D CAM provides downstream channels for as few as one or as many as sixteen different MAC domains.The 32D CAM is designed to run in the client-card slots to the right side of the chassis, beginning with slot 15, then 14, and so on working to the left. It is advisable to begin with slot 14, reserving slot 15 for later use as a spare 32D CAM. The 24U CAM is responsible for upstream RF reception. The 24U CAMs are designed to be installed from left to right in the chassis, beginning with slot 0. For this configuration example, an SCM is installed in Slot 19, and RCM in slot 17, and a 32D CAM will be installed in slot 14. A 24U CAM will be installed in slot 1. In this example, blank slots are available for additional cards. Refer to Figure 11-3 to view the sample configuration. The rear spare Physical Interface Cards (PICs) are different for 24U and 32D CAMs.

If an IPv4 or IPv6 address on a cable interface is changed or removed, or if a subnet mask on a cable interface is changed, then be well aware that all cable modems and CPEs using addresses on the changed/removed IPv4/IPv6 subnet will be stranded. They will have no communication with other cable modems or CPEs. The stranded cable modems and CPEs will remain stranded until they acquire IPv4/IPv6 addresses on a subnet of that interface. Also, CPEs behind a cable modem that is stranded that attempt to acquire an IP address using DHCP will not have access to the DHCP server. This modification or removal includes any IPv4/IPv6 address on a cable interface, either primary or secondary. When an IPv4 or IPv6 address or subnet mask is modified or removed from a cable interface, all IPv4/IPv6 cable modems on that subnet should be reset. 7. Configure Downstream Parameters

This section configures a single 32D CAM in slot 14. The 32D has the following characteristics: •

4 physical connectors: each one can output 8 downstream channels

•

The downstream channel frequencies are grouped eight per connector. For each connector there is an 80 MHz frequency range available for those four channels.

•

DS carriers 0-7 are associated with connector D0

•

DS carriers 8-15 are associated with connector D1

•

DS carriers 16-23 are associated with connector D2

•

DS carriers 24-31 are associated with connector D3

Configure RCC Management

In this Basic Bring-up, the RCC configuration is created while configuring bonding groups in the procedure above. DOCSIS 3.0 allows for two methods of configuring the CM Receive Channel Configuration (RCC). Like bonding group configurations, there can be static and dynamic RCC configurations in Release 7.x and later. The Static method consists of explicitly defining all the different combinations that could occur on any given node with specific downstream channels. For an example of static RCC configuration, see Configuration Examples for Static RCC on page 24-10.

11 Basic Bring-up Procedure

12. Local Authentication

C4/C4c CMTS Rel. 8.0.7

To create a new user on the system, enter:

configure username tempuser password Use the default method list (local database) by entering: configure enable password configure authentication default local configure line vty 0 15 authentication default login-authentication configure line vty 0 15 authentication default enable-authentication

13. Managing the C4 CMTS

Managing consists of various system administration tasks, including those related to accounting, security, and configuration. This is accomplished through in-band or out-of-band management or both. Management functions can use telnet, SSH, SNMP, and other protocols. Among the other management protocols are TOD, IPDR, DNS, TACACS, RADIUS, Syslog, NTP, and Event Messaging and COPS for PacketCable. In-band Management — This means that the telnet/ssh/snmp sessions are carried through the Ethernet interfaces on the RCM line card. Pro: Access Control Lists (ACLs) can be applied to increase security Con: In-band management uses the same interfaces as all the modem traffic. To provision in-band management, permit and define a standard ACL by entering:

configure access-list 1 permit any configure interface gigabitEthernet 17/0 ip scm access-group 1 configure ip scm access

Out-of-band Management — This means that the telnet/snmp sessions are carried through the Ethernet interfaces on the SCM card, so that management traffic is not being carried on the same channels as data traffic. Pro: The IPs can be put on a private network and only management traffic is carried on these links Con: ACLs can not be applied to these interfaces. The interface is 10MBPS and half duplex. The C4 CMTS requires a reboot if these need to be changed. To provision out-of-band management, enter the following commands:

16. Save the Configuration

Write the configuration to memory to save the configurations: write memory

Verification Steps This section provides the procedures to complete the bring-up of your system. 17. Cable CAMs and RCM

In this step, the Operator needs to connect the cables to the CAMs, RCM, and SCM if out of band management is configured. In this example, a single cable from the 16D PIC connected to connector 1 will be cabled to provide service to nodes 1-4. Another 4 cables will be connected to the first four connectors on the 12U PIC on the rear of the chassis. These individual upstreams will then be connected individually to the four nodes per the network diagram in Figure 11-2, Network Diagram Example, on page 11-4.

18. Configure/Verify Back Office Systems

The provisioning servers and other Back Office servers and data collectors should be configured to allow for the first modem to receive IP and CM configurations. Since different offices use various provisioning servers and environments, this procedure is customer-specific and site-dependent.

IPv6 Configuration (Optional) This section assigns the IPv4 subnets and IPv6 prefixes that will be configured in the C4 CMTS. In Release 7.x, the setup of IP subnets and prefixes has been augmented with support for IPv6. This allows the operator to run either IPv4 or IPv6 or both protocols in a chassis. Release 7.x enhancements and changes to the configuration include: •

For installations with 16D CAMs and 12Us, the IPv4 and IPv6 addresses are assigned on a per-MAC domain basis or bundled across multiple MAC Domains.

•

IPv6 addresses cannot be assigned to the SCM ports in Release 8.x.

The C4 CMTS can be configured to prefer IPv6 addressing of DOCSIS 3.0 CMs and DOCSIS 2.0 CMs that have support for IPv6 and still provide IPv4 services to pre-DOCSIS 3.0 CMs. To complete this configuration:

11-22

•

The IPv4 and IPv6 addresses must be assigned to both the RCM interface ports as well as the RF/MAC Domains/CAMs as described above

•

The back office servers used to support the DOCSIS devices as well as CPE must be configured to support both IPv4 and IPv6 operation

IP Address Prefixes and Subnets

When the C4 CMTS is configured for service, the back office systems that support the installation must also be configured and properly setup to support the DOCSIS and non-DOCSIS devices services by the C4 CMTS. This means that if the C4 CMTS is operating with both IPv4 and IPv6 devices, the time servers, provisioning servers (DHCP and tftp) and NMS devices are all capable of operating with either IPv4 or IPv6. Also, the DHCP servers need to be configured with the proper IPv4 and IPv6 address information and the correct DHCP options for both legacy DOCSIS, and DOCSIS 3.0 devices. NOTE In configuring the MAC domain in the procedure above, the IP Provisioning Mode was set to IPv6 only. To support legacy DOCSIS 2.0 CMs on the same channels in the MAC domain, IPv4 addresses must also be configured. Configure the IPv6 on the RF:

Overview

Add a Control Complex (Change from Simplex to Duplex)

2

A control complex consists of one SCM and its associated RCM. The SCM in slot 19 and the RCM in slot 17 make up the control complex in a simplex system. In order to have control complex redundancy (CCR) the CMTS must be a duplex system. In a duplex CMTS both control complexes are equipped; one is active the other is standby. CCR ensures high reliability for system-wide Operations Administration Maintenance and Provisioning (OAM&P), switching, and routing. The control complex redundancy feature provides 1+1 active/standby redundancy between two pairs of SCM/RCM modules. The failure of an active SCM/RCM pair immediately causes a failover to the standby SCM/RCM pair. Key characteristics of control complex redundancy include:

Issue 2.0

•

Reduced customer impact on any SCM or RCM failure (hardware or software)

•

Hot standby SCM/RCM pair with complete replication of configuration and customer data

•

Fault correlation between active and standby SCM/RCM pairs

NOTE Routing protocols restart after a control complex failover. Convergence time varies based upon the specific configuration. For a summary of the types of the SCM card, see Table 7-2, Types of System Control Modules (SCMs), on page 7-4.

Procedure 12-1

Add a Control Complex (Change from Simplex to Duplex) Use this procedure to add a redundant control complex. This procedure assumes that the original control complex (i.e. the SCM in slot 19 and the RCM in slot 17) are in service. NOTE Ensure that your system is committed before starting this procedure. Use the reload commit command if necessary.

CAUTION

Do not insert the SCM 20 or RCM 18 modules until instructed to do so later in this procedure. 1 Configure a second SCM slot: configure slot 20 type SCM 2 Configure a second RCM slot: configure slot 18 type RCM 3 Put slots 20 and 18 in the administrative up state: configure slot 20 no shutdown configure slot 18 no shutdown 4 (Optional) If using out-of-band management, configure the IP address of the second SCM in slot 20: configure interface ethernet 20/0 ip address In the next step you assign the out-of-band ethernet active IP address (19/0 and 20/0). It remains the active IP even after a failover.

NOTE If you are currently using telnet to access the SCM 19, you will be disconnected and have to log back in to the system. 5 (Optional) If SCM 19 does not have an active IP address, assign one using the following command: configure interface ethernet 19/0 active ip [] Where valid slot number = 19 or 20, either can be used to set the active IP. In this case use slot 19 because the SCM is not yet present in slot 20. If the IP mask is not provided, it defaults to the mask of the SCM interface ip address. 6 Save the duplex configuration to memory: write memory 7 Reset the chassis: configure reset system 8 Wait for slots 17 and 19 to go in-service. 9 Insert an SCM card in slot 20 and the associated Even SCM Physical Interface Card (PIC) at the rear of the chassis. (Optional) If applicable to your configuration, add the Ethernet cable to either the front of the SCM card or at the rear of the chassis. 10 Insert an RCM card in slot 18. The SCM and RCM cards in slots 20 and 18 respectively are initialized automatically and come into service when they are inserted. 11 Install the crossover connector between the RCMs. (See chapter 8, Router Control Module (RCM) for more details on the crossover connector installation.)

NOTE The 2Dx12U CAM is not supported in Release 8.0.

FlexCAM™ Hitless CAM Sparing CAM sparing minimizes traffic loss and customer impact in case of a hardware or software failure. When an active CAM in a spare-group fails, the spare CAM takes over. The cable modems that were connected to the upstream and downstream channels on the failed CAM are immediately connected to the spare CAM. Cable modems do not have to re-register and they incur minimal data loss. Failback from the spare CAM to a recovered CAM can be set to take place automatically or manually. CAM sparing is an important element of system reliability. It greatly reduces customer impact and loss of traffic in the event of CAM failure. The spare CAM is used until the failed module is diagnosed, repaired, or replaced, or until there is a software recovery. The service outage is minimized because intervention by maintenance personnel is not required. When a failover occurs, the CMTS automatically reconfigures the spare CAM to take over the functions of the failed module. This includes configuration of downstream and upstream channels and port administrative

status. Depending on how you configure the CMTS, the spare CAM remains the active module or automatically switches back to the original active CAM once that CAM comes back online. CAM Sparing PIC LEDs

The rear slots of spare-group leader CAMs are equipped with sparing PICs. Other CAM slots are equipped with regular PICs. All types of CAM PICs have an LED at the bottom of their faceplates. These LEDs show which CAM in a spare-group has failed and which CAM is its group leader. Under normal conditions all sparing LEDs will be off. When a CAM in a sparegroup fails, traffic is transferred to its spare-group leader. In this case, the sparing LEDs of the failed CAM PIC and of the spare-group leader CAM PIC are on.

Definitions

Failover — Active CAM fails and the spare CAM takes over Failback— The recovered CAM becomes active, taking over for the spare. NOTE If a CAM has failed over to the sparing CAM, the CMTS does not accept the command to remove the failed CAM from the spare-group. You must first fail back to the original CAM, then you can remove it from the sparegroup.

Benefits of Hitless CAM Sparing

A great benefit of Hitless CAM Sparing is the minimal subscriber impact upon CAM failure. When an active CAM goes down, the CMs remain online. When a failover occurs, active CMs typically do not re-register, and they sustain minimal subscriber impact. Inactive CMs may flap after a failover, especially if their CPE IPs have timed out. Other benefits of hitless CAM sparing include: •

Uninterrupted service to the subscriber if a CAM goes down in the middle of a session where the end user is sending or receiving data

•

System administrators can take active CAMs out of service without serious impact

•

Reduces the amount of down time in the event of CAM failure.

The goal of CAM sparing is to preserve data flows such as voice calls, video, best effort, and other subscriber services. Size of Hitless CAM Sparegroups

For example, the CMTS supports 8:1 CAM sparing for the 16D CAM. In other words, the largest possible 16D CAM spare-group has eight active CAMs and one spare.

Guidelines for CAM Spare-groups A spare-group consists of one spare CAM (the spare-group leader) and one or more active CAMs protected by the spare-group leader.

Guidelines for Upstream Spare-groups

Issue 2.0

•

CAMs are not required to be part of a spare-group.

•

A chassis may have several spare-groups, depending on how many slots are used as spares and on the size of the spare-groups.

•

Any CAM can be used as spare-group leader, but it must be the first CAM added to the group.

•

The spare-group must be homogenous: the group leader and all of the members of the spare-group must be the same type of CAM.

•

CAMs from two different spare-groups cannot be interspersed. If slot 8 has been added to spare-group 0, then CAMs 1-7 cannot belong to any CAM spare-group except 0. In the same way, if slot 9 has been added to spare-group 15, then slots 10-14 can only be added to sparegroup 15.

•

There can be an unspared CAM or an unpopulated front slot within a spare-group, but the rear slot must have the correct PIC in it. For example, slot 0 can be the upstream spare-group leader for slots 1, 2, 3, 4, and 6, with slot 5 being either unpopulated or not added to any spare-group. In this case in which slot 5 is unpopulated, rear slot 5 must be equipped with an upstream non-spare PIC. If it is not, a failover from CAM 6 to the spare-group leader in slot 0 would not succeed because traffic on CAM 6 could not be re-routed through the backplane from slot 6 to slot 0.

•

The spare-group leader must have a special Physical Interface Card called a sparing PIC. The upstream Sparing PIC is a different card than the downstream Sparing PIC.

•

If you decide to turn a sparing leader slot into an active one, you may use the same CAM but you must replace the sparing PIC with a nonsparing PIC.

•

An upstream spare-group must be homogenous: a 12U CAM can spare only for other 12U CAMs; a 24U CAM can spare only for other 24U CAMs.

•

Upstream CAM spare-groups are designated by the lowest-numbered slot in the group. The spare-group leader of an upstream spare-group is always the lowest-numbered slot in that group.

13 CAM Sparing

Guidelines for Downstream Spare-groups

Calculating Signal Loss during Failover

C4/C4c CMTS Rel. 8.0.7

•

An downstream spare-group must be homogenous: a 16D CAM can spare only for other 16D CAMs; an XD CAM can spare only for other XD CAMs. All the XD CAM slots in a spare-group must also be provisioned for the same annex.

•

Downstream CAM spare-groups are named for the highest-numbered slot. The group leader of a downstream spare-group is always the highest-numbered slot in that group.

When failover occurs the RF signal to the failed CAM is rerouted from the PIC of the failed CAM through the intervening PICs and backplane to the PIC of the now-active spare CAM. This longer path produces some signal loss. Although station maintenance begins immediately and compensates for the upstream loss, there is a period of at least a few seconds, depending on the number of modems supported, that the signal is weakened.

Configure 12U/24U CAM or 16D/XD CAM Sparing Figure 13-1 provides an example of a chassis equipped with 24U and XD CAMs arranged in spare-groups. Note that the 24U CAM spare-group builds from left to right: its spare is the lowest-numbered CAM in the group. The XD spare-group builds from right to left: its spare is the highest-numbered CAM in the group. For the CAM sparing shown in Figure 13-1 you would need seven nonspare upstream CAM PICs, six non-spare downstream CAM PICs, and two sparing PICs. The five different types of CAM PICs are listed below. TYPE OF PIC

Figure 13-2: Example of CAM Sparing PICs (chassis rear view) To configure the spare-groups shown in the example in Figure 13-1, you would use the commands shown in the procedure below. If using the following procedure for 12U CAMs, enter the CAM slot type 12UCAM instead of 24UCAM. If using 16D CAMs for the downstream, the CAM slot should be 16DCAM instead of 32DCAM-B (Annex B) or 24DCAMA (Annex A).

Procedure 13-1

Use this procedure to create 12U and 16D CAM spare-groups shown in the example shown in Figure 13-1. Automatic failback can reduce exposure to traffic loss because the spare CAM is restored to the standby state as soon as the faulty CAM comes back up. Manual allows you to defer the failback to a more convenient time, such as a maintenance window.

Subinterfaces (Multiple VRIs per VRF) A subinterface is a Virtual Router Interface (VRI), a logical layer 3 interface. Multiple subinterfaces may be defined on a single interface and associated with the same VRF. Multiple subinterfaces may be defined per physical port and associated with the same VRF, such that there is a many-to-one relationship between subinterfaces and VRFs, per cable-side physical interface. The CMTS system administrator must also be allowed to change the association between a subinterface and a VRF. The default VRF is the global VRF that is always present in the CMTS. It can neither be created nor destroyed. Note that upon creation of a subinterface, it is implicitly associated with the default VRF. The relationship of a subinterface to a VRF is many-to-one when viewed from the perspective of a single CAM physical interface or cable bundle. Each ingress cable-side IP packet must classify to one and only one subinterface. This classification to a subinterface will be based solely on the source IP address and source physical port of the packet. For broadcast DHCP packets that have a source IP address of 0.0.0.0, the following rules apply:

14-2

•

If the DHCP packet is sourced from a CM, then the packet will classify to the lowest numbered subinterface that has a DHCP-Server defined.

•

If the DHCP packet is sourced from a CPE, then the packet must be classified to the subinterface of the CPE’s associated CM.

Rules of Operation and Guidelines for Subinterfaces

•

The CMTS supports up to 150 interfaces (both interfaces and subinterfaces count towards the total of 150).

•

A subinterface is associated with the default VRF upon creation.

•

The sum of all subinterface IP addresses may not exceed the total CMTS system limitation of 998 IP addresses. The 998 limit represents all primary and secondary IP addresses associated with each subinterface.

•

The following items may be provisioned per subinterface:

-

•

IP addresses, both primary and secondary DHCP Relay Agent including: primary/policy mode selection, secondary dhcp-giaddr identification, DHCP Lease Query (cable source verify) functionality and DHCP Server IP address definitions - IP filter groups - Directed broadcast support - RIP and OSPF - IGMP - IRDP - SCM access. The DHCP Relay Agent supports the definition of 10 DHCP Server IP addresses per subinterface.

•

The DHCP Relay Agent classifies ingress CM DHCP packets to the lowest numbered subinterface associated for each unique DHCP Server IP address.

•

When the DHCP Relay agent is forwarding a packet originating from a CPE, it will forward the packet using as its giaddr the primary or a secondary address, depending on the dhcp-giaddr mode of the subinterface, that is, of the subinterface associated with the CM that the CPE is behind. The packet will be forwarded to each unique DHCP server IP address for CPEs provisioned on that subinterface.

•

If there are no DHCP servers for CPEs defined for the subinterface associated with the CM that a CPE is behind, then the DHCP Relay agent will forward a packet originating from a CPE to each unique DHCP server IP address for CPEs using as its giaddr the primary address or a secondary address, depending on the dhcp-giaddr mode of the subinterface, in other words, the lowest numbered subinterface provisioned with that server address. This allows MSOs to provide a service where different CPEs behind a single cable modem could be serviced by different ISPs on different subinterfaces. It would require the CMTS to be provisioned such that the CMs and CPE would be on different subinterfaces. In addition, it provides a mechanism where different giaddrs could be sent to different DHCP servers by defining those DHCP servers on different subinterfaces.

C4/C4c CMTS Rel. 8.0.7

The subinterfaces for CMs would be provisioned with DHCP servers marked for use with CMs only, and the subinterfaces for CPEs would be provisioned with DHCP servers marked for use with CPEs only (although DHCP server addresses could be the same values). Example: If the command config router rip network 10.0.0.0 has been executed, then all net10 interfaces are running RIP and will automatically advertise interface (10.x.x.x) IP addresses associated with any subinterface that is defined on the default VRF. •

Subinterfaces cannot be defined for SCM ports.

Interface Configuration Common Interface Configuring Commands This section describes common interface commands which support IP address and helper syntaxes for the 2Dx12U Cable Access Module in the CMTS. How to Configure CAM Interface for DHCP Policy

The following command is accepted only for provisioned CAM slot/port combinations in the system. This command assigns an IP address to the CAM interface and determines its DHCP policy. configure interface cable-mac ip address [secondary] [dhcp-giaddr] Secondary IP addresses become candidates for the dhcp-giaddr field if and only if the keywords secondary and dhcp-giaddr are both used. The command in the example below assigns an IP address of 10.10.1.1 to the specified CAM interface. It enables DHCP policy for this interface — secondary IP addresses are candidates for the dhcp-giaddr field. configure interface cable-mac 5 ip address 10.10.1.1 255.255.255.0 secondary dhcp-giaddr

Configure the Helper (DHCP) Addresses

The following command defines the cable-helper information for a CAM slot/port. This command assumes the default route table. configure interface cable-mac cable helperaddress [cable-modem|host|any]

C4/C4c CMTS Rel. 8.0.7

If no host type is specified, this command defaults to a value of any. This interface is by definition associated with the default router. Configure DHCP Relay Agent Mode for CAM Port

The DHCP Relay Agent needs to be enabled for each CAM port as follows: config interface cable-mac cable dhcp-giaddr {primary | policy} Primary Operation — When the DHCP Relay Agent is defined for Primary operation on a specific CAM physical interface, the Primary IP address of the interface is used to populate the gi_addr field of all DHCP messages originating from either CMs or Hosts (CPEs). Policy Operation — When the DHCP Relay Agent is defined for Policy operation on a specific CAM physical interface, the Primary IP address of the interface is used to populate the gi_addr field with all DHCP messages originating from CMs. For Hosts (CPEs), a designated secondary IP address of the interface is used. If multiple secondary IP addresses are defined for dhcp-giaddr support, then the DHCP Relay Agent uses roundrobin selection, choosing the next entry in the list with each new DHCP transaction.

Monitoring Interfaces After configuring the CMTS interfaces, the system is ready to route traffic. Once traffic is generated, you may view the counters for these interfaces by using the procedures in this section.

Procedure 14-1

How to Monitor Interfaces Execute the following steps from the SCM prompt to verify traffic is being routed through the CMTS. 1 Display information about the virtual interfaces in the system, including data counts: show ip interface The output will look similar to the following (only a portion of output is shown): cable-mac 1.0, VRF: default, IP Address: 10.129.0.1/19 Secondary IP Address(es): No Secondary Addresses

802.1Q VLAN Tagging (Q-tags) MSOs often deploy Layer 3 Virtual Private Networks (VPNs) for commercial customers or other Internet Service Providers (ISPs). They also use VPNs to segregate their VoIP traffic from their data traffic for traffic engineering purposes. The CMTS serves as the Provider Edge (PE) access router. It is required to segregate VPN traffic within the CMTS domain using subinterfaces and Virtual Route Forwarders (VRFs). It must signal the VPN association to the adjacent northbound Provider (P) router. The CMTS does this using a layer 2 virtual circuit (VC) mechanism with 802.1Q Virtual LAN (VLAN) tags embedded in the traffic. This allows a single physical network interface, such as a gigabit ethernet, to host multiple logical subinterfaces identified by Q-tags, thereby multiplexing traffic from multiple VPNs over a single physical link. Normally subinterfaces in the CMTS segregate packets by source IP address (SIP) prefix only. This works well on the cable side, but not on the network side. Network subinterfaces typically have incoming SIPs that belong to remote subnets not hosted by the CMTS. The Q-tag feature extends the existing network subinterface function to include layer 2 VCs based on the presence of a Q-tag containing a VLANid in the ethernet header, as in Figure 14-1.

In this case subinterface traffic that arrives or leaves the RCM port is encapsulated in an ethernet frame that has a Q-tag ethertype (0x8100, as in Figure 14-2) positioned in front of a native ARP or IP ethertype (0x0806 or 0x0800 respectively). Each physical network interface may have from 0 to 255 subinterfaces defined. Each encapsulated subinterface then behaves like a separate physical interface with the Q-tag as the VC identifier.

Figure 14-2: IEEE 802.1Q/p Tag Format

NOTE This feature does not provide true VLAN support as defined by IEEE 802.1Q for switching tagged ethernet frames between ports. It merely uses the Q-tag as a means to multiplex multiple ethernet VCs onto a single physical ethernet link. Q-tags also carry the IEEE 802.1p priority (p-bits). The network subinterface can assign either a fixed priority value to the p-bits for all egress Qtags or a dynamic bi-directional mapping between the IP TOS precedence bits and the Q-tag p-bits for ingress and egress IP frames. Otherwise, the egress p-bits are set to zero by default and ingress p-bits are ignored. IP TOS precedence bits, IP Differentiated Services Code Point (DSCP) bits, Class Selector (CS) bits, and 802.1p priority bits are all defined identically and therefore may be interchanged without any conversion. This capability makes it possible for intervening layer 2 switches to give the appropriate Quality of Service (QoS) treatment to ethernet frames being switched between adjacent routers. Also, the DOCSIS 2.0 service flow TOS overwrite capability may be used to impose a TOS byte on IP frames forwarded by cable modems to the CMTS based on flow classification rules. Thus, dynamic IP TOS precedence bit mapping to Q-tag p-bits at the network subinterfaces allows DOCSIS priorities to be propagated through the adjacent network side layer 2 switches.

Automatic import of the loopback interface into the SCM protocol stack is consistent with existing in-band management functionality. Currently, all RCM-based interface IP addresses are imported into the SCM to allow SCM-based applications to process traffic destined for one of the CMTS interface IP addresses. Packet redirection from the RCM to the SCM is a hardware decision based on the IP packet type. Definitions

Loopback interface — A logical IP interface that is not associated with any one physical interface. It must be reachable via any active physical interface. Active IP address — The IP address that is associated with the FEP of the active SCM, formerly called the floater IP. The active IP address is the one given to the FEP of the active SCM. It must be used for out-of-band SCM management only. When in-band management is enabled, the RCM will not route IP datagrams destined for the active IP address to the SCM.

RCM SCM ECMP AS LSA Characteristics of the Loopback Interface

Router Control Module System Control Module Equal Cost Multi-Path Autonomous System Link State Advertisement

Observe the following guidelines when configuring and administering loopback interfaces: •

The CMTS supports 16 unique loopback interfaces, ranging from 0-15.

•

The subnet mask may be /32; this implies a host address.

•

Upon creation of a loopback interface, it will be associated with the default VRF.

•

If the loopback is taken down, no physical interface is taken OOS.

•

If OSPF is enabled on the loopback interface, the network associated with the loopback address must be advertised in a router LSA. The existing ospf command must be used: network area .

•

Like physical interfaces, a loopback may reside in only one area.

•

Routing protocols (RIPv2 or OSPFv2) will not advertise the active IP address.

•

The active IP address will not have a presence on the RCM.

•

When in-band management is enabled, loopback interfaces associated with the default VRF are imported into the SCM’s protocol stack.

•

If multiple loopback interfaces exist, the lowest value loopback interface is used as the source IP address for SCM-originated IP datagrams.

Figure 14-3, Example of Packet Flow Using Loopback Interface, on page 14-14, depicts a network configuration where a loopback interface is defined for in-band management. In this figure the active IP address is used for out-of-band management. This network topology shows the loopback interface used as the “forwarding address” of OSPF Type-7 LSAs that advertise CAM-side prefixes. Since the loopback interface IP address was previously announced in a Router LSA and is part of the OSPF AS, ECMP is available, from the 6509 to the CMTS, for packets destined for RIP advertised networks.

Dynamic Route Redundancy The Dynamic Route Redundancy (DRR) feature allows the CMTS to dynamically update a specific route in hardware based on a change in the network topology. The update only occurs if a redundant route for a specific IP prefix exists in software. The following events cause the CMTS to recalculate the least cost route and potentially update the hardware forwarding engine: •

The cost of an active route is updated and as a consequence it is no longer the least cost route. The CMTS installs the least cost route from a pool of redundant routes to the specific IP prefix.

•

The physical interface associated with a route is taken out of service. All routes over the physical interface are marked as inactive and are replaced by a redundant route for each IP prefix assuming one exists.

•

RIP or OSPF network topology changes may cause the CMTS to pick an alternative route if the protocol running determines that a route it advertised is no longer reachable.

•

Equal Cost Multi-Path (ECMP) Load Balancing, as it is implemented in the CMTS, is a natural extension to Dynamic Route Redundancy. This feature allows the CMTS to load balance traffic on an IP prefix basis across four unique routes. Load balancing is achieved by examining the source IP address of the IP datagram when determining which of several routes to use. Note that the unique routes must be of the same cost. The cost of a route is determined by the protocol type and metric. If multiple routes to a specific prefix exist with different metrics or protocol types, then only the least cost routes are considered. In this case the CMTS defaults to the previously described DRR functionality, where sub-optimal routes are only used if a least cost route becomes inactive. This first piece of information that must be considered when determining the cost of a route is the protocol type. It takes precedence over the metric value. Local routes have the greatest precedence when determining a least cost route. RIP routes have the least. Protocol precedence is not changeable within the CMTS. Here are the protocol rankings: 1. Local 2. Static 3. OSPF 4. RIP

Configuring IP Static Routes

Procedure 14-2

How to Add/Delete/View a Static IP Route to the CMTS 1 To add an IP Route: configure ip route [metric ] Where the value assigned to the metric parameter defines the weight or cost of the route. 2 To delete an IP Route: configure no ip route 3 To display the IP Routes: show ip route End of procedure

Route Redistribution and Administrative Costing Route redistribution is defined as the ability to import and export IP routing information from one routing protocol domain to another. In addition, Local (CMTS interface networks) and Static (Net Management) routes may be imported into a protocol domain. The dynamic routing protocols RIPv2 and OSPF may be run at the same time. The Route Table Manager (RTM) is responsible for choosing the best group of routes provided by each routing protocol. Its choice is based on the administrative distance assigned to each protocol group. It should be noted this approach requires that the administrative distance of each protocol entity, including static and connected routes, must be unique.

Forwarding Information Base (FIB) — A subset of the RTM RIB contains the “best” routes for each IP prefix. This information is passed to the Active Routes Interface (ARI) and hardware forwarding engine. Routing Information Base (RIB) — A database containing all the known routes learned from various disparate sources (e.g. RIP, OSPF, IS-IS). Routing Protocol Manager (RPM) — Each protocol, including static routes, must have an RPM to communicate with the RTM. Static Route Manager (SRM) — Software entity used to control ECMP for static routes.

Policy-Based Routing (PBR) IP packets are normally directed by routing protocols and route tables, which make forwarding decisions based on the destination IP addresses of packets. Policy-based Routing (PBR) enables network engineers to create policies for packets with matching criteria, causing them to take paths that differ from the next-hop path specified by the route table. To enable PBR, the user must configure a route map and apply it to an interface. PBR is then applied to all incoming packets arriving at that interface. The principal benefits of PBR include the following: •

Forwarding is based not on destination IP address but on packet attributes such as source IP or packet type.

•

Route maps can improve service by enforcing Quality of Service (QOS) sorting at the edge router.

•

Cost-savings can be achieved by segregating slow bulky traffic from time-sensitive traffic.

•

Traffic can be separated according to desired characteristics and load balanced across multiple and unequal paths.

NOTE The route maps used by the BGP routing protocol are part of a separate feature and are not affected by commands to create or configure policybased route maps. For more information on BGP-related route maps, see BGP and Route Maps.

C4/C4c CMTS Rel. 8.0.7

Configuring PBR Configuring PBR involves creating a route map with match and set commands and then applying the route map to an interface. Route map statements can result in a permit or deny action on matching packets. Deny means that normal destination-based routing will be used to forward the packet; permit means that some set command will be used to route the packet. Route maps are given unique names (map-tags in CLI) and can have up to ten statements. Each statement is assigned a sequence number. Because the CMTS supports a maximum of 2,048 route map statements, if each route map contains a maximum of ten statements, the C4/C4c CMTS could support a maximum of 204 route maps. Types of PBR commands:

PBR Match Commands

Issue 2.0

•

match ip address

•

set ip tos

•

set ip precedence

•

set ip next-hop

•

set ip backup-next-hop

•

set ip interface null 0.

The following guidelines should be observed when creating match statements: •

This implementation of PBR can use standard access control lists to match source IP addresses or extended ACLs to specify match criteria for source and destination IP, application, protocol type, or ToS.

•

In any one sequence number (map entry) only one ACL can be specified for the match IP address command. However, multiple match IP address ACLs can be concatenated into the one ACL specified by the sequence number.

•

If the route map is applied to a packet and no match is found, the packet is not dropped; instead, it is forwarded using destination-based routing.

•

If a route map is created with no match criteria, then it will be applied to all packets that come in to the specified interface. All set operations will be performed on all packets (unless the set fails).

•

Only one match statement is allowed for each sequence number. When a packet matches the match statement with the lowest sequence number, only the corresponding set statements in that route-map will be processed. If the set statements fail, then the packet will fall back to normal destination-based routing. The packet will not be checked for additional matches.

Set IP ToS

C4/C4c CMTS Rel. 8.0.7

The set ip tos command is used to set the 5 ToS bits; values 0 through 8 are used (one of the bits is reserved). Table 14-2: Setting ToS Values ToS Value | name

Description

0 | normal

Sets the normal ToS

1 | min-monetary-cost

Sets the min-monetary-cost ToS

2 | max-reliability

Sets the max reliable ToS

4 | max-throughput

Sets the max throughput ToS

8 | min-delay

Sets the min delay ToS

The ToS value for DOCSIS classification is not supported. Set IP Precedence Values

The set ip precedence [number | name] route map configuration command enables you to set the three IP precedence bits in the IP packet header. With three bits, you have eight possible values for the IP precedence; values 0 through 7 are defined. Table 14-3: Setting IP Precedence Values Precedence Value| name 0 | routine

Description Sets the routine precedence

1 | priority

Sets the priority precedence

2 | immediate

Sets the immediate precedence

3 | flash

Sets the flash precedence

4 | flash-override

Sets the Flash override precedence

5 | critical

Sets the critical precedence

6 | internet

Sets the internetwork control precedence

7 | network

Sets the network precedence

The C4/C4c CMTS does not use the new precedence value for DOCSIS classification, but if it is included it can be used in routers or devices north of the CMTS. Set IP Next-hop

14-32

The set IP next-hop command specifies the IP address of the adjacent next-hop router in the path toward the packet's destination. The ipaddress must be the address of an adjacent router. The address must be in the same subnet as the C4 CMTS interface address, but not be the same as the C4 CMTS interface address or the subnet broadcast address. With the set ip next-hop command, the routing table is checked only to determine whether the next hop can be reached, not whether the ultimate destination is reachable. Use the NO version of the command to delete it from a route map. For an illustration see the flowchart in Figure 14-4.

14 Cable and Network IP Configuration

C4/C4c CMTS Rel. 8.0.7

Set IP Backup Next-hop

The set IP backup next-hop command provisions a backup next-hop IP address. If the next-hop ip address is unreachable, then the CMTS uses the backup next-hop address. If it is not provisioned or if the backup-nexthop is unreachable, then the CMTS resorts to normal destination-based routing. Use the NO version of the command to delete it from a route map. For an illustration see the flowchart in Figure 14-4.

Set IP Interface Null 0

The set IP interface null0 command is a way to drop packets. By routing undesired packets to the null interface, the CMTS drops them and prevents them from going to a default route and possibly causing a routing loop.

Some Operational Guidelines

The user should be aware of the following:

Local PBR

Issue 2.0

•

PBR is also applied to packets destined to IP addresses of the C4/C4c CMTS. A misconfigured policy could cause the CMTS not to receive packets that it should receive.

•

The C4/C4c CMTS does not support PBR for IPv6 packets.

•

PBR cannot be used on packets coming in to SCM interfaces 19/0 or 20/0.

•

If a route map matches a packet to an ACL that contains a deny keyword, then the effect of that deny is to cause the packet to be forwarded using destination-based (not policy-based) routing.

•

A route map cannot be changed from permit to deny, or from deny to permit. To make such a change you must first remove the route map, make the change, and add it.

•

If the same sequence number is used in two route map commands in the same route map, then the first one is overwritten by the second.

•

A route map can be created that references an ACL before the ACL is defined. If the route map is used before the ACL is defined, then the packet will be routed normally.

•

The only set interface statement supported is set interface null 0, which is used to drop packets.

•

PBR can work in conjunction with multiple VRFs. PBR is configured on a sub-interface which may be assigned to a VRF also. If a next-hop is used in the route-map command, the next-hop IP needs to be in the same VRF (or the default VRF) as the ingress interface. If no next-hop is specified for the route-map (e.g., a set IP ToS is used without a set next-hop), the packet is routed using the normal VRF routing mechanism.

The C4/C4c CMTS supports local PBR to apply policies to In-band Management port of the SCM. In-band Management (also called SCM access) is enabled by the configure ip scm access command.

The CMTS keeps packet and byte counts for the following events: •

The ACL counter will be incremented when the packet matches the ACL specification. This ACL check is done before the PBR set action is evaluated.

•

A PBR match occurs and the PBR match count is incremented when a packet arrives at a PBR-enabled interface and all of the set commands of the route map work.

•

Packets that match at least one match statement, but then had one or more set statements fail are counted by the PBR failed counter. In practice this means that either the set next-hop or set backup-nexthop failed.

CLI Commands The following table is a listing of the common PBR commands. Table 14-4: Some Examples of PBR CLI Commands Purpose

CLI Command

The first command configures a route map named ReRoute which configure route-map-policy ReRoute permit 100 match ip address 10 matches on access list number 10. The second command overwrites the first and sets the ReRoute map to match on ACL 20. The first command configures route map named ReRoute to match to set the next-hop ip address to 1.2.3.4. The second command overwrites sequence number 100 and sets the next-hop ip address to 5.6.7.8.

configure route-map-policy ReRoute permit 100 match ip address 20 configure route-map-policy ReRoute permit 100 set ip next-hop 1.2.3.4 configure route-map-policy ReRoute permit 100 set ip next-hop 5.6.7.8

This command configures a route map name ReRoute which matches on access list number 30. The packets which match the ACL are forwarded using destination-based (not policy-based) routing because the route map type is deny.

configure route-map-policy ReRoute deny 200 match ip address 30

Deletes the route map named ReRoute.

configure no route-map-policy ReRoute

Deletes only sequence number 30 from the route map named

ReRoute.

configure no route-map-policy ReRoute 30

Configures a local policy route map named my_route_map.

configure ip local policy route-map-policy my_route_map

Specifies the IP address of the adjacent next-hop router in the path toward the packet's destination.

C4/C4c CMTS Rel. 8.0.7

Multiple VRFs Overview The Mutliple Virtual Routing and Forwarding (Multiple VRFs) feature of the C4 CMTS was developed primarily to support multiple service providers. Virtual routing is a form of policy routing that allows the administrator to assign subscribers to an ISP via simple IP interface configuration on the C4 CMTS. The administrator is responsible for programming the DHCP server to assign the proper IP addresses to the subscriber CMs and CPEs. However, the C4 CMTS must allow for multiple network configurations, including DHCP servers that vary in location and number. Separate routing tables are maintained for each VRF. Each data packet routed through the C4 CMTS is associated with a VRF and is routed using the corresponding route table. Multi VRF Functionality

•

Both cable and network side interfaces can be configured and assigned to a VRF instance. Network side interfaces can use QTAGs to create logical subinterfaces which may be assigned to a VRF. Cable side interfaces use the SIP of the ingress packets to associate a logical subinterface with a VRF instance.

•

Multiple instances of VRFs can be created each with its own route table. Dynamic routing protocols can be configured in each VRF (i.e. OSPF, RIP). Static routes can be configured into each VRF.

•

A default VRF instance is always automatically created. This VRF is a superset of all of the interfaces in other VRFs. This VRF is used for management traffic which is sourced or synchronized to the C4 CMTS (e.g. Telnet, SNMP, Ping, DHCP, etc.). The default VRF has a special property where it may route traffic to any other VRF.

•

Data traffic is isolated by VRF. Data traffic between two devices within the same VRF scope will be routed within the C4 CMTS. Data traffic between two devices in separate VRF scopes will not be routed within the C4 CMTS unless explicitly configured.

Virtual Routing and Forwarding

The C4 CMTS can support up to a total of eleven (11) VRFs: the “default” VRF plus ten additional VRFs with the following restrictions: •

Static routing is supported in all 11 VRFs

•

OSPFv2 can be supported in up to 5 VRFs

•

RIPv2 can be supported in up to 5 VRFs

•

BGP, IS-IS, and OSPFv3 are supported in only one VRF, which must be the “default” VRF.

•

Multiple protocols can operate in the same VRF (e.g., a common example is to have RIPv2 and OSPFv2 operate in the same VRF with RIP being redistributed into OSPFv2).

•

Even though the CLI may allow for configurations beyond the restrictions described here (e.g., more than 11 VRFs), those configurations are not supported.

Overview of the Sample Procedure The configuration example that follows is for demonstration purposes. Such a configuration is not likely to be encountered in the field, but it serves to show what commands are available.

Issue 2.0

•

In the example below we use the default VRF and create four additional ones. You may configure five non-default VRFs: just substitute a new vrf (vrf5) for the default.

•

This sample procedure has RIP being redistributed into OSPF and OSPF being redistributed into RIP in every VRF. This is not a recommended configuration. MSOs might configure one VRF with RIP into OSPF and another VRF with OSPF into RIP, but in most cases you will see only RIP redistributed into OSPF.

•

This procedure also has one RCM interface and one cable-mac in each VRF. You can have multiple interfaces (RCM or cable-macs) in a VRF. One VRF does not have to match the other VRFs in terms of the number of interfaces. The default VRF, for example, could have three RCM ports and four cable-macs. VRF1 could have only one RCM port and three cable-macs, and so on.

The procedure above is for demonstration purposes. Adapt it to the requirements of your site and application. •

You may configure five non-default VRFs: just substitute a new vrf (vrf5) for the default.

•

This sample procedure has RIP being redistributed into OSPF. MSOs might configure one VRF with RIP into OSPF and another VRF with OSPF into RIP, but in most cases you will only see RIP redistributed into OSPF.

•

This procedure also has one RCM interface and one cable-mac in each VRF. You can have multiple interfaces (RCM or cable-mac) in a VRF. One VRF does not have to match the other VRFs in terms of the number of interfaces. The default VRF, for example, could have three RCM ports and four cable-macs. VRF1 could have only one RCM port and three cable-macs, and so on.

15 Dynamic Routing Protocols

C4/C4c CMTS Rel. 8.0.7

Border Gateway Protocol (BGP) This section outlines the basic configuration tasks required to implement Border Gateway Protocol version 4 (BGP-4) functionality in the CMTS. The CMTS supports a full complement of features associated with Interior BGP (I-BGP) and Exterior BGP (E-BGP), with a few noted exceptions. BGP runs only on the default VRF, but is also supported on subinterfaces that are not on the default VRF. Some MSOs use BGP as the protocol of choice for advertising CMTS CAMside IP prefixes. In such an application I-BGP is used throughout their regional networks with a full mesh of interconnected peering routers. The CMTS in this environment is required to run I-BGP peering sessions with various routers in a particular Regional Area Network (RAN). I-BGP peers typically communicate using loopback interfaces. Loopback interfaces are not assigned to any particular interface; therefore, a particular BGP session is not interrupted by an interface failure. Interface IP addresses may also be changed without impacting BGP sessions. Typically, I-BGP networks require the following: Definitions

•

BGP Autonomous System: A routing domain in which all routers are associated with the same AS. I-BGP peering sessions occur within an AS.

•

BGP Route Reflector: A route reflector supports the readvertisement of routes between I-BGP peers.

•

BGP Route Reflector Client: Depends on a route reflector to advertise its routes to the entire BGP AS.

BGP Confederations and Route Reflection Since I-BGP full mesh topologies scale at a rate of N(N-1)/2, two methods have been developed to reduce the number of BGP peering sessions. The first method breaks the Autonomous System into smaller entities. This method is termed AS confederations. Figure 15-1 depicts a BGP autonomous system that is broken down into sub-ASs. Within each sub-AS, a full mesh exists between all peers; however, a single E-BGP peering session is sufficient for interconnection between sub-ASs. Note that from the perspective of ASs outside of the confederation, the original AS does not appear any different. That is, the sub-As configuration is contained with-in the original AS.

Figure 15-1: Figure 1: I-BGP with Confederations to Reduce Full Mesh Peering Route reflectors are commonly used to reduce the number of peering groups. This second method is detailed in Figure 15-2, showing a complete RAN running I-BGP with route reflection. This network topology provides a substantial scalability benefit to the CMTS in that it does not need to establish a peering session with each BGP enabled router in the RAN. To allow BGP sessions to be established between peering routers via loopback interfaces, the routers must communicate the reachability of the various loopback interfaces. Typically these interfaces have a network mask of /32. Advertisement of loopback interfaces is accomplished using an overlay OSPF network. In this example, each region is defined as a RAN with a single OSPF area. OSPF summarization occurs at each area border router, and therefore OSPF SPF calculations occur for each RAN.

BGP Attributes BGP attributes are applied to the complete group of routes in the BGP Update message. The CMTS supports the following BGP-4 attributes: •

Origin: Indicates how the IP prefixes became known to BGP. -

• •

Next-Hop: Identifies the next hop for the group of routes. This could be a third-party next-hop.

•

Multi-Exit-Discriminator: Allows for choosing the optimal link for a group of routes when more than one connection exists between two ASs.

•

Local-Pref: Allows for choosing the optimal link for a group of routes when multiple connections exists to different intermediate ASs.

•

Aggregator: Identifies the AS that performed route aggregation.

•

Communities: Ability to associate a unique identifier with a route. The following well-known communities are supported:

•

15-6

IGP: Prefix was learned from an interior gateway protocol (e.g. OSPF). - EGP: Prefix was learned via EGP. - Incomplete: Protocol was learned from a source other than IGP/EGP. For example, static or local routes. AS-Path: A list of ASs the group of routes has passed through.

- No-Export: The route must stay local to the AS. - No-Advertise: The route must stay local to the router. - No-Export-Subconfed: The route must stay local to a sub-AS. Extended Communities: Needed for route targets on VPN-IPv4 routes.

•

MP-(Un)Reach-NLRI: Multi-protocol attribute needed for carrying VPN-IPv4 routes.

General Notes on BGP Function in the CMTS The following points are meant to help understand the BGP-4 implementation on the CMTS:

Issue 2.0

•

BGP-4 on the CMTS complies with RFC 1771 and the MIB RFC 1657.

•

Definition of BGP-4 on the CMTS is for either E-BGP or I-BGP. If the CMTS is used in an E-BGP configuration, it must be for an MSO’s internal network only. Given the size of the CMTS hardware routing table, approximately 32k routes, the CMTS must not be defined as an AS-border router running E-BGP to the internet.

•

The CMTS supports a single instance of BGP, and it must be on the default VRF.

•

I-BGP routes have a default administrative distance of 200.

•

E-BGP routes have a default administrative distance of 20.

•

BGP-4 supports Autonomous System Confederations. This feature is useful in reducing full mesh configurations in I-BGP. A BGP AS is split into multiple sub-ASs. Within a sub-AS, there is a full mesh of I-BGP.

•

BGP-4 supports Equal Cost Multi-path. In addition to being supported for E-BGP, ECMP must be supported when multiple next-hops exist for a prefix within an AS. This implies ECMP is available for I-BGP configurations. The allowable range for ECMP is 1-4 routes. A value of 1 implies that ECMP is disabled.

•

BGP-4 supports Route Reflection. This is an alternative to full mesh IBGP. A route reflector is responsible for re-advertising routes to an entire AS, but a route reflector client requires no additional functionality beyond the original BGP specification.

•

BGP-4 supports the Communities Attribute: this allows similar routes to be grouped for the same policy treatment

•

BGP-4 sends BGP Updates on card/port maintenance state changes. For example, if port maintenance indicates a state change in a CAM subnet, this change triggers a BGP Update to all peers indicating the reachability of the CAM-side subnets.

•

BGP-4 supports Route-Refresh. This feature allows the CMTS to dynamically request a re-advertisement of the Adj-RIB-Out from a BGP peer.

•

BGP-4 supports Capabilities Advertisement. This feature is required to advertise BGP capabilities to peers, such as route refresh. When VPN extensions are available and two BGP speakers wish to exchange labeled VPN-IPv4 NLRI, they must use BGP Capabilities Advertisement to ensure both peers are capable of processing such NLRI.

•

The CMTS, acting as a BGP Server, allows for a socket bind to any provisioned CMTS IP interface, including loopback interfaces. For IBGP connections, loopback interfaces are the preferred IP address

15 Dynamic Routing Protocols

C4/C4c CMTS Rel. 8.0.7

when establishing connections since they represent the router itself and not any particular interface that is subject to state changes.

BGP and Route Maps

15-8

•

Additionally, the CMTS supports binding to a “wildcard” address. A “wildcard” address is assumed if the “update source” parameter is not defined during the creation of a BGP instance.

•

BGP supports Route Reflector Client (RRC) and Confederation, but does not support peer groups or route filtering. In the anticipated use of the CMTS as an RRC, there will be only a handful of routers north of the CMTS. Therefore, the neighbor commands contain the ip addresses of the neighbors, but not of peer groups.

•

The CMTS supports BGP route filtering, which is required for CMTS peers with multiple ISPs and is recommended in confederations. Without this filtering, the CMTS could advertise routes received from one peer to another peer, becoming an unintentional transit router.

•

The CMTS permits system administrators to redistribute static, connected, RIP, or OSPF routes into BGP.

•

The CMTS supports BGP Route Aggregation.

Support for the BGP routing protocol requires more complicated filtering of routes. This type of filtering is beyond the syntactic definition of distribute-lists. Distribute-lists rely on standard ACLs to filter on a destination IP prefix. For BGP, route-maps may be used to control the redistribution of IP routes from BGP into another protocol (match functionality) or to redistribute routes from another protocol into BGP (set functionality). MIB support built into the routing protocol software allows for the following BGP filtering to be used for route redistribution (in addition to destination IP address filtering): •

Next-Hop: Allows route redistribution to be controlled based on the advertising router (next-hop). May also be used with other routing protocols

•

BGP Community Number (match or set): 4 byte value identifying a BGP community

•

BGP Extended Community Number (match or set): 8 byte value identifying a BGP community

•

BGP Origin (set): Allows the origin attribute to be set for routes redistributed into BGP

•

Multi-Exist Discriminator (set): Allows a MED attribute value to be set for routes redistributed into BGP

•

Local Preference: Allows a Local Preference attribute to be set for routes redistributed into BGP.

BGP Route Redistribution

BGP route maps may be applied to redistribution commands having the following form: configure router bgp redistribute [metric ] [route-map ] Where: AS is the name of the Autonomous System routing-protocol is either static, connected, RIP, ISIS, or OSPF Route maps applied by the command above are limited to the following four commands: configure route-map set community [] [none] [local-AS] [no-advertise] [no-export] [internet] configure route-map set local-preference configure route-map set metric configure route-map set origin {igp | egp | incomplete} Where: word is the name of the route map Route maps may contain other commands, but these commands will not be applied to route redistribution.

Provisioning (CLI commands, MIBs, etc.) Below is a table with the CLI commands that are used for configuring and using BGP routing together with a brief description. For more information on these commands and their parameters, see CLI Command Descriptions. NOTE BGP requires a unique router-id to function correctly. The default routerid is computed from the IP addresses of the interfaces. If there are no interfaces configured, then the CMTS displays an error message that reads “No Interfaces have been assigned to this VRF, default router-Id cannot be calculated.”

Intermediate System-Intermediate System (IS-IS) Overview IS-IS is a routing protocol developed by the ISO. In this link-state protocol, IS routers exchange routing information based on a single metric to determine network topology. It is similar to Open Shortest Path First (OSPF) in the TCP/IP network. The C4/C4c CMTSs support: •

both IPv4 and IPv6

•

Q-tags with IS-IS traffic for both IPv4 and IPv6

•

approximately 30,000 IPv4 routes or 10,000 IPv6 routes in the IS-IS populated routing table.

NOTE IS-IS runs only on the default VRF. This version of IS-IS does not support multiple VRFs. Abbreviations

CLNP Addressing/NSAP Address Format The CLNP node-based addressing scheme is one of the concepts retained for use in advertising IP networks. CLNP network addressing is mandatory on IP routers and therefore both CLNP and IP addresses need to be provisioned on the CMTS. The CLNP address is analogous to an IP loopback interface in so far as it is node-based versus interface-based. As such, a single CLNP address suffices per IS-IS node, within a specific IS-IS area. Each CLNP (NSAP) address is composed of three parts: an area identifier (area ID) prefix, followed by a system identifier (SysID), and an Nselector. A group of routers within a specific area shares the same area ID. IS-IS routers may be multi-homed, implying they reside in multiple Level 1 areas (or Level 2 backbone) and therefore require multiple NSAP addresses. Since IS-IS is an IGP, the NSAP addressing scheme need not be globally unique and private IP addresses may be defined within an AS.

IS-IS Network Topology, Unique Level 1 Areas IS-IS defines a multi-layered hierarchy called Level 1 and Level 2 routing. Level 1 routers belong to a common area and are engaged in level one routing. These routers are aware of their local topology only and require Level 2 routers to communicate inter-area routing information. In practice, most Level 2 routers are also Level 1 routers; that is, they serve a local area and connect to the IS-IS backbone. Figure 15-3 depicts an IS-IS two-level network topology with both NSAP and IP addressing. NSAP addresses are based on the defined IP loopback addresses and must be manually provisioned as such. Each router in a Level 1 area builds an area unique LSP database with its peers. Disjointed Level 1 areas must be joined together via a Level 2 (backbone) area.

By default, Level 1 areas are considered “stub” areas because they rely on a default route to forward traffic out of the area. However, route leaking from Level 2 and Level 1 areas allows for more intelligent inter-area routing. In Figure 15-3 IP hosts are not assigned NSAP addresses and do not in any way participate in IS-IS routing. Adjacencies formed are based on interface circuit-type (either Level 1, Level 2, or both) and the provisioned area ID in the NSAP address. Note: the circuit-type is encoded in the IIH packet. Figure 15-3 defines the following adjacencies: •

Router R1: Circuits are Level 2 only since the router resides completely in a Level 2 area. R1 will form Level 2 adjacencies with R2 and R3.

•

Routers R2 and R3: These routers are considered Border routers since north-bound circuits are defined as Level 2, and south-bound circuits are defined as Level 1. R2 defines adjacencies with R1 and R5 while R3 defines adjacencies with R1 and R4.

•

Routers R4 and R5: Circuits may be defined as Level 1 only since these are edge routers connected to the IS-IS backbone.

Dynamic Hostname Support The CMTS will support use of the dynamic hostname in IS-IS link state packets (LSPs). As described in RFC 5301, the CMTS will support the use of TLV 137 to communicate its hostname and receive hostname updates from peer routers. In the IS-IS routing domain, a system ID is used to represent each router. The system ID is part of the network entity title that is configured for each IS-IS router. The dynamic hostname mechanism uses link-state protocol (LSP) flooding to distribute the router-name-to-system-ID mapping information across the entire network. Every router on the network will try to install the system ID-to-router name mapping information in its routing table. If a router that has been advertising the dynamic name type, length, value (TLV) on the network suddenly stops the advertisement, the mapping information last received will remain in the dynamic host mapping table for up to one hour, allowing the network administrator to display the entries in the mapping entry during a time when the network experiences problems. Entering the show isis hostname command displays the entries in the system-ID-to-router-name mapping table.

IS-IS Network Topology — Multi-homing Multi-homing is the ability to define multiple NSAP addresses, one per area. Effectively, multi-homing merges multiple IS-IS areas into one large unified area. The LSP database thus becomes unified across the individual Level 1 areas. It should be noted that IS-IS multi-homing is not analogous to the IP concept of sub-interfaces with multiple secondary IP addresses. IP multi-homing implies that multiple logical subnets can be defined on the same physical link. The primary purpose of IS-IS multi-homing is to merge otherwise disparate Level 1 areas. Multi-homing provides the benefit of not having to take down an IS-IS network during as NSAP address renumbering, IS-IS area merging, or IS-IS splitting.

Packet Flow between IS-IS Systems IS-IS defines three packet type categories, similar to that defined in OSPF: Hello packets, Link State packets, and Sequence Number packets. As is the case with OSPF, Hello packets are used to establish and maintain adjacencies between directly connected IS-IS neighbors. Link State packets are used to distribute the actual IP routing information and Sequence Number packets control the distribution of Link State packets to allow for correct synchronization of the Link State database.

Designated Intermediate System (DIS) and Reliable Flooding of LSPs The DIS is sometime referred to as the Pseudonode, which is an abstraction for representing broadcast links as network nodes. This reduces the amount of router-to-router communications on a broadcast network and as a consequence, reduces the amount of information (IS-IS PDUs) that is exchanged when multiple nodes interconnect on a LAN. The election of the DIS is based on interface priority and, as a tie breaker, the MAC address used to encapsulate the Hello packet. As is the case with OSPF, the DIS plays the critical role of LSP flooding; however it should be noted that unlike OSPF, there does not exist the concept of a backup DIS (known in OSPF nomenclature as a BDR). If the DIS becomes unavailable, then DIS election must be restarted. To help mitigate a DIS outage, the hello interval for DIS routers is set at three times the rate of non-DIS routers. This scheme allows for quick detection of DIS failures and replacement. In addition to flooding responsibilities, the DIS will advertise a pseudonode LSP, which represents the broadcast link itself. This LSP has a zero cost and allows for communication on the broadcast link between individual non-DIS routers. The DIS router is not guaranteed to remain the DIS if a

new router with a higher priority shows up on the LAN; likewise, there is no mechanism for making a router ineligible for DIS operation. IS-IS peers are said to be adjacent after Hello packets are exchanged but before the LSP database synchronization is complete. This differs from OSPF, and may cause transient routing problems when adjacent routers do not have a complete forwarding table representing routes within the ISIS domain. Use of the LSP overload bit can help solve this issue by informing adjacent routers that traffic should not be sent to a router whose LSP overload bit is set. On broadcast links, periodic flooding by all IS-IS nodes is used to ensure that adjacent peers maintain a consistent view of the LSP database for a particular IS-IS Domain. That is, all IS-IS nodes broadcast their LSPs to all attached devices. These flooded LSPs are not acknowledged and require support from the DIS to maintain a consistent view of the LSP database. To help support reliable flooding of LSPs, the DIS periodically sends out a CSNP that contains a summary of every known LSP within the IS-IS domain. To purge a LSP from the IS-IS domain, the remaining lifetime field is set to 0, and the LSP is flooded throughout the network. Only the originator of the LSP may purge it from the domain.

Multiple Topology IS-IS (MT IS-IS) Overview This section describes how the CMTS will implement MT IS-IS based on RFC 5120. While the feature fixes the limitations of the current IS-IS IPv6 implementation and maintains the current IS-IS IPv6 functionalities, the CMTS software will support only two topologies in Release 8.0: a topology for IPv6 and a common topology for IPv4. IS-IS for IPv6 was implemented in Release 7.4 (per RFC 5308 - Routing IPv6 with IS-IS). IS-IS could be configured as IPv4 only, IPv6 only or IPv4IPv6 only but only a single SPF (Shortest Path First) would run per level for IPv4 or IPv6. To overcome the single SPF limitation, MT IS-IS is being implemented in the CMTS. When MT IS-IS is enabled, the CMTS will maintain multiple instances of the IS-IS routing tree and will run two separate SPFs — one for standard topology IPv4 and the other for IPv6 topology.

Area 2

Area 1

IPv4 only IPv4-IPv6

Figure 15-4: Example of IS-IS and MT IS-IS Topologies In Figure 15-4, Router B in Area 1 is IPv4 only and all other routers are IPv4-IPv6. If MT IS-IS is not enabled, the best path from A to D is A -> B -> C -> D but any IPv6 traffic from A -> D would be lost in Router B. When MT IS-IS is enabled, two separate SPFs will run and maintain two separate topologies — IPv4 and IPv6. As a result, the best IPv4 path from A to D is A -> B -> C -> D and the best IPv6 path from A to D would be A -> E -> F -> C -> D.

Adjacencies Users need to know what they are running, IPv4 or IPv6, in order for the adjacency to be included in the correct topology. If the interface only supports the IPv4 topology, the CMTS will not use the new MT TLV in the IS-IS Hello packet and it will not be advertised in the new TLV. Thus, the exclusion of MT TLV in the IIH implies that this interface is only part of the IPv4 topology.

Broadcast Interface Adjacencies All the routers on a LAN that implement the MT extension may advertise their MT capability TLV in their IIHs. If there is at least one adjacency on the LAN interface that belongs to this MT capable router, the corresponding MT IS Reachable TLV will be included in its LSP. Adjacency will always be established between two routers on a LAN whether they have a common MT or not. This guarantees that all the routers on the LAN can correctly elect the same DIS. If the CMTS receives an LSP from another router with an unsupported MT, the LSP will be installed into the database but no routes will be calculated using that LSP.

Advertising MT Reachable Intermediate Systems in LSPs The CMTS will include within its LSPs (in the Reachable Intermediate TLVonly) adjacent nodes that are participating in the corresponding topology and advertise such TLVs only if it participates itself in the corresponding topology. There is no change to the pseudo-node LSP construction. The Standard Reachable Intermediate Systems TLV is acting here as MT IPv4 (ID #0), the equivalent of the newly introduced MT Reachable Intermediate Systems TLV. A router must announce the MT IS TLV when there is at least one adjacency on the interface that belongs to this MT, otherwise it may announce the MT IS TLV of an adjacency for a given MT if this interface participates in the LAN. To display the current configuration, use the show isis database detail command.

MT IP Forwarding The CMTS will support MT IPv4 (ID #0) and MT IPv6 (ID #2) on the same interface. Each MT belongs to a Distinct Address Family and routes learned within that topology will be installed in a separate RIB. The RIB associated with MT IPv4 (ID#0) is the default IPv4 VRF. To display all active IPv4 routes in this RIB, use the show ip route isis command. To display all active IPv6 routes in the RIB associated with the IPv6 (MT#2), use the show ipv6 route isis command.

Configuring MT IS-IS on the CMTS There are only two new commands introduced as part of the MT IS-IS implementation. Procedure 15-1 is used to enable or disable MT IS-IS. The second, Procedure 15-2, is needed only if the default IS-IS IPv6 metric of 10 needs to be changed.

Procedure 15-1

Use the following procedure to enable/disable MT IS-IS on the CMTS NOTE IS-IS must be disabled at the system level before enabling or disabling MT. To enable MT IS-IS, use the following steps: 1 Disable IS-IS at the system level with the following command:

C4#configure router isis shutdown 2 Enable MT IS-IS on the CMTS: C4#configure router isis address-family ipv6 multi-topology 3 Once MT IS-IS has been enabled, IS-IS can once again be enabled with the following command: C4#configure router isis shutdown no

To disable MT IS-IS, use the following steps:

Show commands The following section contains a group of commands most commonly used to display MT IS-IS information. To display the IS-IS neighbor output including the remote router’s MT setting, use the following command: C4#show isis neighbor The system output would look similar to the following: Sys Adj System ID Interface SNPA State Hold Type Type Circuit Id Protocol -------------- ---------------------- -------------- ----- ----- ---- ---- ------------------- -------0100.8500.9001 gigabitEthernet 17/9.0 000b.45b6.0100 Up 9 L1/2 L1 TR11.01 M-ISIS 0100.8500.9001 gigabitEthernet 17/9.0 000b.45b6.0100 Up 9 L1/2 L2 TR11.01 M-ISIS

NOTE If the connected router does not support MT IS-IS, the protocol will display IS-IS in the above output. If the neighbor row says ‘IS-IS’, it only indicates that the remote IS is using regular IS-IS TLVs on that interface. The CMTS can still send MT TLVs based on its own system/interface configuration. The CMTSs MT support can be verified using the show isis protocol command. If you are not seeing IPv6 routes and you think you should, then an inconsistent configuration between the C4 CMTS and the northern router may be the cause.

15 Dynamic Routing Protocols

C4/C4c CMTS Rel. 8.0.7

Open Shortest Path First (OSPF) OSPF is a dynamic link state routing protocol developed by the Internet Engineering Task Force (IETF). OSPF: •

Supports Classless Inter-Domain Routing (CIDR)

•

Provides for routing update authentication, both simple and MD5

•

Uses IP multicast when sending/receiving the updates

•

Responds quickly to topology changes with a smaller amount of routing protocol traffic.

The OSPF specification is published as Request For Comments (RFC) 2328. Link State Routing Protocol Description

The OSPF routing protocol maintains a link state database of all subnets available on the network. This includes details about which routers are attached to the links. If a link goes down, the router that is directly attached to it immediately sends a Link State Advertisement (LSA) to its neighbor routers. Information about the link state propagates throughout the network. Each router reviews its database and re-calculates the routing table independently.

Routing Metrics

A router learns multiple paths to a particular destination network and chooses the path with the best metric in its routing table. Different routing protocols use different types of metrics. Rather than counting the number of hops as a metric, OSPF bases its path descriptions on link states that take into account additional network information. OSPF also lets the user assign cost metrics to each interface so that some paths are given preference. OSPF uses a user-defined cost for each interface. This cost is added together for each hop when calculating the cost of a route. This metric could be the same as number of hops if each interface along the route uses a cost of 1. The cost of the route displayed by the show ip route command is the sum of the interface costs.

ECMP

OSPF also has the concept of ECMP (Equal Cost MultiPath) routes. These are routes to the same dest IP (destination IP address) and prefix which use different next hop IPs but the same cost. The CMTS can distribute packets across at most four ECMP routes. ECMP routes can also be used with static routes. The CMTS bases its choice of best route first on longest prefix, then route type (local, netmgmt, OSPF, RIP), and finally on route cost.

Configuring OSPF This section outlines the tasks required to configure a network and CMTS for OSPF. The procedures and commands in this section assume that IP addresses have already been configured for the network and OSPF interfaces. The sequence includes: 1 Reviewing a network diagram for interface information and architecture. 2 Enabling OSPF globally. 3 Configuring the network according to standard configuration parameters: set router id, hello timer, dead timer, network type (broadcast, point-topoint, virtual link), and authentication. 4 Verifying OSPF is running as configured. It is beyond the scope of this User Guide to supply recommendations for reviewing network architecture for all OSPF configuration possibilities; however, the following sections identify the CLI commands required for basic OSPF configuration on the CMTS.

Procedure 15-3

How to Enable OSPF Use this procedure to enable OSPF on the CMTS: 1 Enter the following command to give the default router an identification number: configure router ospf vrf default router-id 1.1.1.1 Where: 1.1.1.1 is the router ID 2 By default, OSPF is disabled on the CMTS. Enter the following command to enable OSPF: configure router ospf vrf default no shutdown There is no system response if the command is successful. This is a “silent success” command. 3 By default, OSPF is disabled for all interfaces. Enabling OSPF for an interface does not affect the global enable/disable state on the CMTS. Enter the following command to enable OSPF for an interface: configure router ospf [vrf default] network area

The "Packets" in the "show crypto ipsec sa" display should be increasing on one outbound IPSec SA and increasing on one or more incoming IPSec SAs per peer. This is a good hint that the intended traffic (COPS and/or Event messaging, for example) is flowing through the IPSec SAs. If IKE and/or IPSec SAs fail to be created properly, the first step should be to manually compare the Phase 1 and Phase 2 security parameters configured on the CMTS and the IKE peer to ensure compatibility. The next step is to inspect the CMTS syslogs to diagnose the problem. Make sure that INFO syslogs are enabled as this is where much IKE and IPSec information is recorded.

authentication — the process of identifying an individual administrator, usually based on a username and password. authorization — the process of granting individuals access to system resources or functions based on the level of service assigned to them. accounting — the process of tracking an individual's activity while accessing a system’s resources, including the amount of time spent on the system, the services accessed, and amount of data transferred. line — a point of origin for CLI sessions. The CMTS supports a single console line (the SCM serial port), and up to sixteen virtual terminal lines (telnet sessions). vty — Virtual terminal

The AAA Model

The AAA security model is an architectural framework for the implementation and management of common security functions within a network of heterogeneous elements. The model distinguishes authentication (verification of a user’s identity) from authorization (verification that a user’s actions are permissible) and offers accounting services with respect to both. Moreover, the model separates security policy from policy enforcement, thereby enabling a distributed security scheme with centralized policy management for each independent function. Figure 32-1 provides a network-level illustration.

Figure 32-1: AAA Security Model In Figure 32-1, the CMTS and the Router are AAA clients that defer login authentication and command authorization responsibilities to remote servers. Information regarding each authentication or authorization exchange is forwarded to accounting servers where historical records of user activity are maintained. Note that the AAA model itself does not demand a distributed security scheme but simply offers enough flexibility to accommodate it. Any or all of the AAA functions can be administered locally at an element. For example, an element can defer login authentication to a remote authority while authorizing each command locally based on element-specific policy such as the user’s privilege level. Similarly, an element can authenticate locally (e.g., from a password file) while deferring authorization to an external server on a per-command basis. TACACS+1 is a TCP-based protocol supporting distinct request/response transactions for authentication, authorization, and accounting. TACACS+ supports full payload encryption via Message Digest version 5 (MD5) and offers authentication for a wide variety of user services including login, Point-to-Point Protocol (PPP), Serial Line IP (SLIP), privilege-level change (e.g., entering enable mode), and password change. It employs an unbounded, server-controlled challenge-response mechanism in which the server may issue any number of challenges to a user prior to accepting or 1.

rejecting a service request. If the server rejects a service request, the client drops the connection. Otherwise, the client establishes the service parameters (e.g., session timeout, idle timeout, privilege level) as directed by the server and initiates the service. Only TACACS+ directly supports authorization for user activities via independent request/response transactions. With TACACS+, the client forwards each user command along with any associated arguments to the server where the accept/reject decision is made. On acceptance, the server may add additional arguments to the command line or may even override the entire argument list. The client is responsible for executing the accepted command with the server-supplied argument additions or overrides. TACACS+ supports both shell and command accounting. The client autonomously forwards start-of-service and end-of-service information to an accounting server. This information can include the number of bytes or packets transmitted or received, the elapsed time in seconds, the reason for termination, and so on. For shell accounting, successful authentication represents the start of service and session termination represents the end of service. For command accounting, successful authorization represents the start of service and command completion represents the end of service. Line Interfaces

Login and enable services are available via telnet sessions over the SCM maintenance ethernet interface and via the SCM console. Since each interface offers a different level of physical security, each may require a different level of AAA services or possibly none at all. Cisco refers to these interfaces as “lines” and provides AAA configuration capabilities on a perline basis. The line interface is also the target of non-AAA configuration parameters such as data rate, session timeout value, idle timeout value, pagination, and line password. Cisco’s line interface model is included as part of this feature.

AAA Functions Supported by the CMTS

Since the CMTS does not support network-based services such as PPP or SLIP, only login and enable services are considered for authorization. Only command services are considered for authorization for similar reasons.

A line is any point of origin for a CLI session. The CMTS currently supports two types of lines: console lines and vty (virtual terminal) lines. A console line is a CLI session over the SCM’s console port, while a vty line is a CLI session over telnet. All lines are independently configurable. This allows an operator to modify the configuration of a given line without affecting the configuration of other lines of the same type. For example, a user logged in on vty 0 may disable/enable pagination without disturbing the state of pagination on vty lines 1 through 15. The following is a summary of the provisioning of the line interfaces: •

Configuration information includes at least session timeout, idle timeout, pagination mode, and password. The C4 CMTS maintains unique parameter values for one console line and sixteen vty (telnet) lines numbered 0 through 15. The session timeout provides the maximum session length in seconds. A value of zero (default) indicates no timeout. The idle timeout provides the maximum idle time in seconds. A value of zero (default) indicates no timeout. The pagination mode provides the number of lines of consecutive output to display before pausing and prompting. A value of zero (default) indicates no pagination. The password provides the line password used for authentication if line-based authentication is active. By default, the line password is undefined.

•

The configuration of login authentication, enable authentication, authorization, shell accounting, and command accounting services are supported on a per-line basis.

•

By default, there are two console lines, consoles 0 and 1. Console 0 is the new-start configuration port and is physically secure.

•

C4/C4c CMTS Rel. 8.0.7

Vty lines are not new-start configuration ports and are not necessarily physically secure. They exist only if they are manually configured. This implies that telnet services are not available on the CMTS by default. •

By default, login authentication is disabled on all lines. Until authentication is manually configured, access to any of the configured lines is granted without challenge.

•

By default, enable authentication is disabled on all lines. Until enable authentication is manually configured, access to enable mode on any of the configured lines is granted without challenge.

•

By default, authorization is disabled on all lines. Until authorization is manually configured, any command may be entered on any line without challenge. Note that this does not include the enable command. The enable command represents a change of privilege level; therefore, it is subject to authentication rather than authorization.

•

By default, accounting is disabled on all lines. Until accounting is manually configured, no authentication or authorization activities may generate accounting records.

•

All line configuration information persist across system reboots and power-cycles. This includes line-specific parameters (e.g., time-outs, baud rate), authentication information, authorization information, and accounting information.

Common CLI Commands for AAA Using TACACS

Use the following command to configure TACACS+ servers and TACACS+ server groups. Each server may be configured with an IP address, shared secret, TCP port number, and timeout value. Each group may be configured with a group name and one or more TACACS+ servers. All hosts are automatically assigned to the TACACS+ server group named tac_default. NOTE This TACACS+ tac_default group will not exist until a configure tacacs host command has been completed (i.e., there is no empty group with this name).

Servers 10.9.8.7 and 10.9.8.6 use the default timeout value of 0 which implies no timeout, while server 10.9.8.5 uses the timeout value of 4. All servers are members of the default TACACS+ server group, while servers 10.9.8.7 and 10.9.8.6 are assigned to TACACS+ server group group1.

Feature Description

C4/C4c CMTS Rel. 8.0.7

SSH is a secure user authentication and connection protocol that operates over TCP/IP. The following characteristics apply to the CMTS implementation of SSH2: •

SSH can work with insecure legacy remote connection protocols such as Telnet and FTP, or can be configured to replace them

•

SSH clients connect to SSH servers using TCP port 22

•

SSH multiplexes multiple sessions over a single TCP port. UDP is not supported.

•

SSH uses encryption to secure all traffic in the connection

•

Connection cipher is auto-negotiated from a list of candidates such as 3DES, Arcfour, Blowfish, etc.

•

A Diffie-Hellman key exchange establishes the transmission key for the SSH session

•

SSH can use passwords or user public keys to authenticate users

•

The CMTS SSH2 server supports secure CLI login

•

The CMTS also supports SSH-EXEC (enables use of SSH within PERL).

NOTE Secure CLI looks and performs the same as existing CLI. Users must enter an enabling password to execute configuration commands. After successful user authentication, the SSH2 server creates a CLI shell process. SSH2 Security Highlights and Compatibility

CLI Commands

SSH2 allows for the following security features: •

Users can be authenticated via user public keys (instead of only passwords)

•

User passwords and enabling authorizations may be authenticated via TACACS

•

SSH2 is not backward compatible with SSH1

•

The CMTS supports SSH protocol version 2 (SSH2) only

•

SSH2 clients include openSSH for Unix, and PuTTY, SecureCRT® & SecureFX® for Windows.1

CLI commands are provided to configure, operate, and maintain the SSH2 server.

Managing User Public Keys

To add a user public key to the CMTS, follow these steps: 1 Consult Table 32-3, Supported Key Formats, on page 32-19 2 Upload the user's PEM- or SSH2-formatted public key files into the following location on the CMTS: /system/sec/ssh/user. 3 The user public file must have the following naming convention: .pem or .pk2 where the User Name is the user’s login name. 4 Use legacy FTP to upload the user's public key file only — do not upload the private key file!

Verification of SSH and PuTTY Setup

Use the following to procedures to set up SSH on the CMTS and to use the PuTTy utility for public key authentication.

Procedure 32-4

Setting up SSH on the CMTS 1 If you have executed the configure crypto key generate dsa command (Setting up the SSH Server, page 32-15), you should have a /system/ssh/server directory. Use the cd command to enter that directory. cd /system/ssh/server If not, use mkdir to create the directory. 2 Generate the public and private keys: configure crypto key generate dsa 3 Restart the SSH2 server: configure ip ssh restart End of procedure

5 A file will be created called ".pem". This is this user's public key file and must be sent using FTP to the CMTS running SSH. Place the file in /system/sec/ssh/user. You may have to create the /user directory. 6 At the CMTS, restart the SSH server: configure ip ssh restart 7 From your PC, run PuTTYgen. PuTTYgen can be downloaded from: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html 8 On the menu bar select Conversions --> import key. Open the private key file you created above called id_dsa.pem. If you entered a pass phrase when the key was created you will be prompted to enter it again. 9 Click the Save private key button to save the private key file with a ".ppk" extension; call it .ppk or something that correlates it with the username you entered above. This is PuTTY's private key file format and is different from OpenSSH and ssh.com (IETF SECSH). 10 From your PC, open PuTTY. Create a profile for connecting to the SSH server. On the left side of the PuTTY window you will see a pane called “Category”. Select Connection --> SSH --> Auth, and in the “Private key file for authentication” browse to the public key file (the .ppk file you converted with PuTTYgen). Go back to 'Sessions'. Enter the IP address, SSH, Name of 'Saved Session' file and save your profile. 11 Connect to the CMTS. Login with , whatever filename you called the .pem public key file you FTP’d to the CMTS. If you entered a pass phrase you will be prompted to enter this as well. Proceed to login to the CMTS in the same way as with telnet. End of procedure

Default is port 22.

Session idle timeout (minutes)

ip ssh idle-timeout

Default is 0 (unlimited). Note well that CLI time is in minutes but SSH2 server time is in seconds.

Max SSH clients

ip ssh max-clients

The default is 0, but the value of zero represents the maximum number available. The maximum number of SSH clients is equal to the number of enabled vty lines. So if the max-clients parameter is set to 5, then the maximum number of clients is 5. If it is set to 0, and there are 16 vty lines enabled, then the maximum number of SSH clients is 16.

Choice of cipher set (choose any or all)

ip ssh ciphers [aes] [blowfish] [cast] [arcfour] [3des]

Available ciphers are aes, blowfish, cast, arcfour, and 3des. Default is all ciphers are available.

Allow/Disallow password authentication

ip ssh password-auth ip ssh no password-auth

Password authentication is allowed. If disallowed, any password authentication from the client is rejected. If both password and public key authentications are disallowed then all client authentication requests will be rejected. Default is allowed.

Allow/Disallow user public key authentication

ip ssh public-key-auth ip ssh no public-key-auth

User public key authentication is allowed. If disallowed then any public key authentication from the client is rejected. If both password and public key authentications are disallowed then all client authentication requests will be rejected. Default is allowed.

Require/Do Not Require ip ssh password-auth-req password ip ssh no password-auth-req authentication

The server requires password authentication before a client is considered logged in. Password authentication must be allowed; otherwise, this command has no effect. If not required, the client can choose whether or not to use password authentication. Default is not required.

Require/Do Not Require ip ssh public-key-auth-req public key ip ssh no public-key-auth-req authentication

The server requires public key authentication before a client is considered logged in. Public-key-auth must be allowed, otherwise this command has no effect. If not required, the client can choose whether or not to use public key authentication. Default is not required.

Require/Do Not Require ip ssh public-key-auth-first public key ip ssh no public-key-auth-first authentication first

If both password and public key authentications are required, this command requires public key authentication to be performed first. If it is not required then the client can choose in which order to authenticate. Default is not required.

Max number of client authentication failure

Server rejects a client authentication if the number of failed authentication ip ssh max-auth-fail attempt exceeds this number. This counter is for both public key and password authentication failures. Default is 3.

Allow/Disallow secure CLI login sessions

ip ssh login ip ssh no login

Secure CLI login sessions are allowed. If disallowed, then no CLI sessions are available. Default is allowed.

Allow/Disallow secure port forwarding

ip ssh port-forwarding ip ssh no port-forwarding

Port forwarding is allowed. If disallowed, then no port forwarding is available. Default is allowed.

Allow/Disallow legacy Telnet connections

Table 32-5: CLI Commands for Generating SSH Server Host Key CLI Command

Description Generate the host private/public key pair for the CMTS SSH server. Specify dsa format for the SSH2 server. The DSA host public key may be distributed to clients before an SSH session is started. To maintain security, the host private key should never be copied off the CMTS.

configure crypto key generate dsa

Note well that this command does not start the CMTS SSH server daemon process (see CLI command configure ip ssh no shutdown). Also, the SSH server’s host public/private key pair(s) must be created before the SSH server is started. This means the DSA key pair must be created for the SSH2 server. This command does not appear in the show running config command output. Delete the SSH server’s host public/private key pair(s).

configure crypto key zeroize dsa

If the SSH2 server is running and the DSA key pair is deleted, the server will terminate immediately. Prerequisites: it is desirable to use the configure ip ssh shutdown command to stop the SSH server before deleting any of its host key pairs.

Routing to a Null Interface A null interface is a pseudo-interface that can neither receive nor forward packets. Any packets routed to a null interface are dropped. Routing to a null interface is a way to filter traffic that is simpler than using Access Control Lists. It functions like a global Access Control List (ACL) since a single entry in the routing table applies to all ingress interfaces. With this feature enabled, the CMTS system administrator can define a route in the CMTS routing table to a null interface. A Classless InterDomain Routing (CIDR) match with this defined route on the destination IP address of an ingress IP datagram results in the dropping of the packet. Routing to a null interface can be used to discard certain IP prefixes in order to remove the potential for routing loops. By default the packets routed to the null interface are discarded silently, but the CMTS can be configured to return an Internet Control Message Protocol (ICMP) “destination unreachable” error to the source IP. The cost of the route is zero by default, but it can be increased by user command. CLI Commands

To enable the sending of ICMP unreachable messages: configure interface null 0 ip unreachables The only valid interface number for this command is 0. The result is global.

Source Verification of Cable-side IP Addresses The CMTS Cable Source Verify feature is intended to eliminate hostinitiated corruption of the layer 2 and layer 3 address spaces on the cable network. The feature adds a source IP address verification phase to the IP address learning process of the CMTS. Each unknown source address received in an IP, ARP, or ND packet on a cable-side interface is subjected to a configurable series of address validation checks prior to learning. If any check fails, the address remains unlearned and all IP, ARP, and ND packets sourced from that address are dropped. The CMTS examines source addresses of directly connected hosts to verify that their IP addresses do not belong to other hosts. Also, the CMTS inhibits the traffic of an indirectly connected host if the return route to that address is not via the cable modem that originated the packet. Source Verify via Internal Database — The CMTS maintains an internal database (MAC DB) of CPE source IPs (SIPs), MAC addresses, and associated CMs. The database is populated through DHCP snooping for dynamically assigned CPE IP addresses or through either MAC learning or DOCSIS® pre-provisioning for statically assigned CPE IP addresses. This database along with the routing tables serves as the default authority for SIP verification. Source Verify via DHCP Server — This facility allows the CMTS to query a DHCP server for the CM MAC address associated with a given SIP when that SIP is not present in the MAC DB of the CMTS. It does this using a DHCP LEASEQUERY message. Cable Source Verify supports multiple versions of the lease query protocol for IPv4. For IPv6 there is only one version.

C4/C4c CMTS Rel. 8.0.7

Source Verify via Authoritative DHCP Server — With authoritative DHCP lease query, any indication returned by the DHCP server that indicates that the server has no knowledge of the address results in denial of packet forwarding. This implies that all CPE IP addresses (whether directly attached or not) will be either dynamically assigned by the DHCP server or statically reserved at the DHCP server. New for IPv6

Users of Cable Source Verify and IPv6 should be aware of the following: Lease Query Option 47 — The C4 CMTS verifies IPv6 source address leases based on the association of the CPE with the CM. If a CPE is using an IPv6 source address assigned by the DHCPv6 server to a CPE behind a different or unknown CM, then these packets will be denied. This requires that the DHCPv6 server respond to a request for a lease query option 47 (OPTION_LQ_RELAY_DATA) which contains the CM MAC address. If the DHCPv6 server does not or cannot provide this option, then these packets will be denied by the CMTS. IPv6 Address Learning and Invalid IPv6 Prefixes — If Cable Source Verify is enabled, then any IPv6 source address using an expired prefix will not be learned. If any IPv6 prefix expires or is deleted, the CMTS removes all of the learned IPv6 source addresses using that prefix from the MAC database and from the CAMs. NOTE If Source Verify is enabled in DHCP authoritative mode, and if an IPv6 prefix is advertised for auto-configuration, then hosts attempting to autoconfigure their IP addresses using that IPv6 prefix will be denied.

CLI Commands

The following command enables source verification for all packets for the specified mac-id: configure interface cable-mac cable sourceverify [dhcp [authoritative]] Use the following command to select the desired version of the DHCP lease query protocol: configure cable source-verify leasequery version [draft-0|draft-2|draft-4|rfc-4388] Where:

draft-0 is the default.

Where:

type = a number from 9 to 13, representing the message type value when operating in one of the draft protocol modes

When the CMTS is operating in RFC 4388 mode, the RFC-defined values are always used. To determine how the CMTS is configured for cable source verification, run the following command: show running-config full verbose | include source-verify Or … show ip interface cable-mac A sample response from the CMTS: configure interface cable-mac 1.0 cable source-verify dhcp authoritative

CPE Host Authorization The CPE Host Authorization feature provides an alternative or a supplement to DHCP Lease Query, also known as Cable Source Verify. It is another means of preventing the spoofing of IP addresses. It permits the CMTS operator to provision multiple IP addresses to a single MAC address. When the CAM receives a packet from an unknown source MAC address or from a known MAC address having an IP address that differs from the previous MAC-IP binding, a learning event is generated by the hardware. This new information is forwarded to the RCM. There, the MAC Data Manager (MACDM) performs several checks for source verification before assigning an IP address to a MAC address. If the request satisfies all the checks, the new learned information is added to internal databases of the CMTS and copied into the CAM hardware. NOTE CPE Host Authorization is not supported for IPv6 addresses. The following list describes the additional checks used by this feature to govern the flow of CPE traffic through the system: •

Issue 2.0

When the host authorization feature is turned on, packets from an unknown source will be dropped.

C4/C4c CMTS Rel. 8.0.7

Packets from unknown sources currently are dropped only if Cable Source Verify is on or if subscriber management cpe control is on for the particular modem. This feature adds one additional condition to cause packets from an unknown source to be dropped. •

If a CPE MAC learning event indicates that a MAC address has moved from being active behind one modem to being active behind another where it has been provisioned as having authorized IP addresses behind the new modem, the movement is not denied. Currently, the MAC learning event prohibits an active MAC from being moved to a new modem if source verify is on. This requirement supersedes that check if host authorization has been provisioned for a CPE behind a modem.

•

If host authorization is enabled and a CPE IP learning event occurs for an IP address that has been provisioned for host authorization, and the learning event indicates a different CM or CPE than the one provisioned, then the IP learning will be denied. The CMTS issues an error message:

IP address authorized for use by CM xx:xx:xx:xx:xx:xx/ CPE xx:xx:xx:xx:xx:xx. •

If host authorization is enabled and a CPE IP learning event occurs for an IP address that has been provisioned for host authorization, and the learning event indicates that the correct CM and CPE have been provisioned, and furthermore, if other source verify checks pass, and the MAC is not currently assigned an IP address, then the IP learning is allowed and the IP address is assigned with the type IPTYPE_PROVISIONED. If other source verify checks fails, then the MAC/IP binding is denied for those other reasons. One of those other checks performed ensures that a less secure source does not take away an address from a more secure source. CPE Host Authorization is considered more secure than DHCP, for example. So when a match with host authorization table occurs, the IP type is changed to IPTYPE_PROVISIONED. This prevents the less secure/more secure check from retracting that IP address.

32-28

•

If a CPE IP learning event occurs for an IPv4 address that has been provisioned for host authorization, and host authorization is enabled, the learning event indicates the correct CM and CPE that have been provisioned, all other source verify check pass, and the MAC is currently assigned an IP address, then the IP learning will be allowed, but instead of assigning the MAC address the new IP address, the new IP address will be added behind the MAC as a /32 subnet in the CAM hardware.

•

When a host authorization IP address is removed from the provisioning, if that IP address is currently assigned to a MAC address, that IP address for that MAC address is cleared. Because adding and

removing IPs is expected to be rare, a situation in which a MAC address does not have primary addresses but does have secondary addresses is permitted. •

When a host authorization IP address is removed from the provisioning, if that IP address is currently not assigned to a MAC address, the /32 subnet for that IP address is deleted from the CAM hardware.

•

When a host authorization IP address is added to the provisioning and host authorization is enabled, that IP address is checked to see if is entered in the MAC Database (MACDB) behind the wrong CM or CPE. If a mismatch is found, the IP address in the MACDB is invalidated.

•

When host authorization is enabled, each entry in the host authorization table is checked to see if an entry exists in the MACDB associating that IP address with the wrong CM or CPE. If a mismatch is found, the IP address in the MACDB is invalidated.

•

When a host authorization MIB table entry is created, a check will be made to see if any other entries have been made with the same CPE MAC address, and if so, the new entry’s CM MAC address will be the same as the existing entry’s CM MAC address. If it is not the same, then the new creation is rejected.

•

When a host authorization MIB table entry is created, a check is made to see if there are other entries using the same IP address. If the same IP address is already used, the new creation is rejected.

The CMTS supports a maximum of 1000 MIB entries in the Host Authorization table and up to 32 entries for a single CPE/MAC address. CLI Commands

The CPE Host Authorization feature is enabled or disabled with the following command: configure cable host authorization To create a static mapping between an IP address and a CM/CPE MAC pair use the following command: configure [no] cable host authorization cpe The NO version of the command above deletes the static mapping. To see which MAC addresses are associated with which IP addresses, use the following command: show cable modem detail If a secondary IP is being used by a given MAC address, the system response labels it SEC IP, not SUBNET.

The following CLI command can be used to alter timers on the CMTS: configure cable max-qos-admitted-timeout Default =

200

configure cable max-qos-active-timeout Default =

30

NOTE If DSx DQoS VoIP is enabled, the admitted timeout should be set at 200 seconds (the default), and the active timeout should be set to 30 seconds. This command is for DSx DQoS; it has no effect on PacketCable. The defaults ensure that inactive resources are released. Increasing these default values or setting them to 0 (which represents infinity) is not recommended. The default values serve as a precaution for freeing resources in the event that any device or transmission path in the network does not perform as required.

CMTS Advanced CM Configuration File Verification A common type of theft-of-service occurs when users replace or modify their assigned configuration files in order to gain a higher class of service. Another type of theft-of-service occurs when subscribers crack the Message Integrity Check (MIC) in order to generate their own high bandwidth configurations with valid MICs. The implementation of this feature consists of two parts, TFTP Enforcement to ensure that modems are using the configuration files downloaded from the proper server, and Dynamic Shared Secret Verification, which uses a Message Integrity Check (MIC) modified by the CMTS to verify that these files have not been altered. This feature can be applied to all modems or selectively to all IPv4 or to all IPv6 modems. Modems found to be in violation are called rogues. Operators can take action against them in the following ways:

Issue 2.0

•

Reject the modem by preventing it from registering

•

Lock the modem by limiting the CM’s bandwidth to 10 kbps

•

Block Internet access by preventing the CM from learning any CPEs

•

Mark the modem by indicating in show commands that the CM registered incorrectly, but allow it to register with full function.

The Block and Lock settings also serve to deny CM requests for dynamic service flows. TFTP Enforcement

TFTP Enforcement is configurable on a per-MAC domain basis. If enabled, it is applied equally to all modems in the MAC domain. The CMTS implements this feature by relaying Trivial File Transfer Protocol (TFTP) requests and responses between the cable modems and TFTP servers, while monitoring the contents of the configuration files. After a modem receives an IP address from the DHCP server, it requests its TFTP configuration file. The CMTS verifies that the file name in the TFTP request is correct and relays the request to the correct server. By default TFTP Enforcement is disabled.

Dynamic Shared Secret Verification

Dynamic Shared Secret Verification is configurable on a per-MAC domain basis. If enabled, it is applied equally to all modems in the MAC domain. Before sending the correct configuration file to the CM, the CMTS extracts information from the file, stores it for later verification, and modifies the CMTS MIC using a secret key. When the modem sends up its registration request, the CMTS confirms that the information in the registration request matches the information gathered during the TFTP transfer. If the registration information is valid, the registration is allowed to proceed normally. If the CMTS detects a MIC mismatch it assumes that the cable modem’s configuration file has been altered. The CMTS verifies the MIC by dynamically creating a shared secret when the cable modem is registering, and using this key to create a new MIC which only the CMTS can verify. This shared secret is valid only for that particular session with that particular cable modem. A new dynamically generated shared secret is used each time the cable modem registers. By default this function is disabled.

TFTP Relay Agent and the Upgrade Server TLV

If a TFTP server sends a cable modem configuration file that contains an upgrade server TLV that is null, then the TFTP relay agent populates the TLV with the IP address of the TFTP server. If the TFTP server sends a cable modem configuration file that contains an upgrade filename TLV that does not contain an upgrade server TLV, then the TFTP relay agent inserts an upgrade server TLV with the IP address of the TFTP server. The upgrade server TLV is not added or altered unless the configuration file contains an upgrade filename TLV and the upgrade server TLV is missing or zero. If the relay agent does modify a configuration file by adding the IP address of a server, it recalculates and overwrites both the CM MIC and CMTS MIC TLVs. And if the addition of a TLV by this feature causes the an additional TFTP data block to be sent to the modem, then the TFTP relay agent coordinates how the CM and TFTP server will handle that extra data block. This TFTP relay agent functionality makes it possible to use one set of CM configuration files across a large network where there are multiple TFTP servers with different IP addresses.

Option 125, Sub-option 2

This applies only when the CMTS is acting as a TFTP relay agent when the TFTP Enforce feature or the Dynamic Shared Secret feature is enabled. This option uses the Vendor Identifying Vendor-Specific (TLV 125) for CableLabs (OID enterprise 4491) and is called the DHCPv4 TFTP Servers Option. This option was introduced in DOCSIS 3.0 and applies only to DOCSIS 3.0 (and higher) IPv4 modems. When DHCP OFFER or ACK messages are sent to a DOCSIS 3.0 modem, and if those messages contain option 125 data for enterprise 4491 and sub-option 2, then the CMTS derives the TFTP server address from the first IP address contained in suboption 2. Only the first TFTP server is supported. If other servers are specified in sub-option 2, they are ignored. If this TLV and sub-option contain no data, then the CMTS derives the TFTP server address from the siaddr field.

DHCPv6 Servers Address— Option 32

Because the CMTS acts as a TFTP relay agent for IPv6 CM registration, this option is always required. The CMTS derives the TFTP server address from DHCPv6 advertise and reply messages that contain option 32. The C4/C4c CMTS supports only the first TFTP server address specified in Option 32. If other servers are specified, they are ignored and removed from the message.

Cable Modem MAC Deny List This feature enables MSOs to prevent certain cable modems from obtaining IP addresses from the C4 CMTS. The purpose of this feature is to prevent malicious subscribers from cloning MAC addresses, changing configuration files, sending virus attacks, or initiating ping storms. The CM MAC Deny list supports a total of 1,000 CM MAC addresses. When MSOs detect the same MACs on multiple systems, they can add them to the deny list on the CMTSs where those MACs do not belong. If a malicious user is detected by the C4 CMTS, his or her modem can be added to the MAC Deny list. Whenever a CM MAC address is added to this list, that modem is prevented from acquiring an IP address. When a modem on the MAC Deny list attempts to range and register, the C4 CMTS generates a debug logging message showing the time of the attempt, the interface, and number of attempts so far. MAC-Deny Modems are not included on the modem flap list. Their attempts to register are not included in the flap count. The list of MACDeny modems is not provided by the show cable modem command. See Table 32-8 below for the CLI commands that pertain to this feature. Table 32-8: CLI Commands for Provisioning the CM MAC Deny List Purpose Add [remove] a CM MAC to the list.

Overview The CMTS Legal Intercept (LI) feature provides operators a standardsbased mechanism for meeting legal requirements to intercept all IP data and voice traffic originating from or destined to subscribers on their network. The feature supports the Simple Law Enforcement Monitoring (SLEM) concept outlined in RFC 3924 to enable the interception of all IP traffic associated with a subscriber’s cable modem. See Figure 33-1 for an illustration of the RFC 3924 framework. The SLEM approach relies on the CISCO-TAP-MIB (cTapMIB) to support the secure remote configuration of tap sessions with one or more Mediation Devices (MDs) via SNMPv3 (or local configuration via CLI) and to specify the data streams to be intercepted. In the CMTS, the only data stream specification that is supported in the cTapMIB is the current layer 2 (aka an 802 stream) “subscriber interface” designated by the CM MAC address (or any MAC address of a bonded CM) that is registered to the subscriber. In this model, the subscriber’s CM may be offline when the tap session is configured or it may reboot and move to a different downstream

Figure 33-1: RFC 3924 Framework For a modem that is being tapped, the CMTS will encapsulate both IPv4 and IPv6 traffic. The encapsulation header will be an IPv4 header, but the data encapsulated can be either an IPv4 or IPv6 packet. This means the CMTS will replicate and encapsulate all traffic with an ethertype of either 0x0800 or 0x86dd. ARP traffic (ethertype 0x0806) is not tapped. The CMTS supplies the captured packets to an MD that handles the collection of this information for delivery to the Law Enforcement Agency (LEA). Tap sessions are managed using SNMPv3 control. This feature includes an implementation of the cable intercept CLI command set that permits local configuration of tap sessions as well. NOTE For security reasons Legal Intercept should be configured for SNMPv3 access only.

Feature Operation

The operation of this feature includes the following highlights: 1 Feature activation is transparent to the subject. 2 The feature provides authentication, auditing, and logging mechanisms to prevent unauthorized creation or detection of intercepts. 3 Supports 320 simultaneous Service Independent Intercept (SII) taps. (Note: A maximum of 127 subscribers can be set up with LI Taps on each 12U CAM due to hardware limitations.) 4 Support for FlexPath Contributing Cable Modems (CCMs) by configuring the same tap session for each CM associated with the bonded Flexpath CM group. 5 Support for co-existence of Legal Intercept and PacketCable Electronic Surveillance (Note: PacketCable Electronic Surveillance takes precedence over LI in flows created by PacketCable 1.x). 6 Content delivery encapsulation format is compatible with PacketCable Electronic Surveillance. 7 Support for activation of tap sessions for CMs that are not currently registered at the CMTS. 8 Support for tap sessions that persist across CM reboots. 9 Support for data stream specification at Layer 2 (802 stream) only, as designated by a CM MAC address. 10 Support for tap sessions across all DSx activity. 11 The CMTS supports taps on IPv6-registered cable modems. 12 The output of the show running config command encrypts the identity of a subscriber intercepted by a config cable intercept command and suppresses userid and password values that may have been used to execute the command. 13 Only one LI tap session per subscriber is permitted. Any attempt to add a second tap or to change the parameters of the existing tap are rejected. The existing tap must be deleted before it can be replaced or altered.

33 Legal Intercept

C4/C4c CMTS Rel. 8.0.7

The Legal Intercept request can be configured directly using the CMTS and the configure cable intercept CLI command. It can also be done using a MD and SNMPv3. The CLI and the SNMPv3 agent have simultaneous access to the same underlying cTapMIB object. Therefore, the operator must manage simultaneous access appropriately. For security reasons the cable intercept and show cable intercept commands are password protected by the same user ID and password used to authorize remote SNMPv3 access to the CMTS by the MD. The userid and password created in the following procedure are set by the snmp-server command to restrict access to the MIB view and are the same for the configure cable intercept command.

CLI Commands The following section provides the commands used to create and manage secure access.

Procedure 33-1

Sample Configuration for Secure Access and Tap The following procedure serves as an example of how to create a view, group, and user for secure access. The names chosen here for the view, group, and user are arbitrary. 1 To create the view to manage access: configure snmp-server view cTapMIB included An example using a view named LI-TAP-VIEW: configure snmp-server view LI-TAP-VIEW cTapMIB included 2 To define the administrator group with read/write access:

configure snmp-server group v3 noauth read write notify

An example using a group named LI-TAP-ADMINS: configure snmp-server group LI-TAP-ADMINS v3 noauth read LI-TAP-VIEW write LI-TAP-VIEW notify LI-TAP-VIEW

3 To add a user to a group: configure snmp-server user

NOTE No spaces are allowed in the user name. An example using user name JohnDoe and password TopSecret: configure snmp-server user JohnDoe LI-TAP-ADMINS v3 auth md5 TopSecret

4 Use the following command to set the source interface for the SNMPv3 messages and the UDP/IP encapsulated intercept traffic. If you do not use this command to set the source interface for LI, then the CMTS uses the same source interface value that is used for SNMP traps. configure snmp-server trap-source loopback | cable / | cable-mac | ethernet / | gigabitEthernet / | loopback | tengigabitEthernet /

For example: configure snmp-server trap-source loopback 0 5 To define which SNMP traps should be sent: configure snmp-server notify-filter profile LI-TAP-NOTIFY subtree cTapMIBNotifications type included

6 Enter config-cable-intercept mode: configure cable intercept User Id: JohnDoe Password: TopSecret 7 The CM MAC address may be used to indicate which subscriber is to be intercepted: C4(config-cable-intercept)# subscriber [disable|enable] md udp [tos ] until [userid ] [password ]

An example using the subscriber’s CM MAC: C4(config-cable-intercept)# subscriber 0001.0203.aaaa md 192.168.100.199 udp 12345 until 06/19/2010

The md, udp, and until keywords are required when creating a new LI tap session. If no time is specified for the until option, it defaults to 23:59, at which time the session will be removed. Use the disable option to create a tap session that is inactive but that you wish to activate later. Use the tos keyword only if you wish to override the default value of 0x22 for UDP/IP encapsulation. Use the no form of the command to delete the LI tap session. 8 (Optional) To remove the tap created in the previous step, enter the following command: C4(config-cable-intercept# no subscriber 0001.0203.aaaa

Load Balancing prevents any one channel from becoming overburdened so long as excess capacity is available on another reachable channel. The feature may perform this function through both static and dynamic load balancing. Static load balancing is performed at initial channel assignment time during a CM’s registration process. Dynamic load balancing automatically moves modems from one upstream channel to another, and/or from one downstream to another (including from one CAM to another) after registration. In this chapter, various aspects of load balancing are described. Immediately following the description is one or more boxes containing a brief description of the CLI command(s) used to provision that aspect.

Load Balancing Group Definitions General Load Balancing Group (GLBG)

A general load balancing group (GLBG) represents the set of upstream and downstream channels which reach a single fiber node. In this arrangement, a CM connected to the fiber node would be able to tune to any (or possibly all) of the channels in the general load balancing group. Since the CM may be associated with only one MAC Domain at a time, only the channels associated with a common MAC Domain may be used simultaneously. Unlike previous CMTS releases, in Release 7 and later, general load balancing groups are calculated by the CMTS when the fiber node command is entered with MAC Domain channels. The CMTS will automatically create a general load balancing group for each MAC Domain-Cable Modem-Service Group (MD-CM-SG). As a requirement for load balancing, any unique Upstream or Downstream channel pair must only be configured behind a single fiber node. The CMTS supports cross-MAC Domain dynamic load balancing across all CAM types, including 12U, 24U, 16D, and XD CAMs (24D and 32D).

Default Parameters for New GLBGs

The operator may choose to provision the default parameters to be used for all GLBGs yet to be created. Changes to these default parameters will not affect GLBGs which are in existence when the change is made if those groups have been specifically provisioned with their own parameters.

Restricted Load Balancing groups are provisioned for a specific set of cable modems. Modems can be added or deleted from a Restricted Load Balance Group by either specifying the RLBG group number in the CM configuration file in TLV 43.1 or by adding a service type to the group and the modems in CLI commands. NOTE All load balancing groups that are manually provisioned are restricted groups.

A general load balancing group is automatically created by the CMTS to correspond to each MD-CM-SG so general load balancing group provisioning is not necessary. Restricted load balancing groups may be provisioned as subsets of the MD-CM-SG. Any CM which is not placed into a restricted load balancing group will be placed into the general load balancing group for its MD-CM-SG if its place in the cable plant topology can be determined.

Load Balancing Policy

A Load Balancing Policy is described by a set of conditions (rules) that govern the load balancing process for a cable modem. A policy may be referenced by multiple load balancing groups. A policy ID value is intended to be a numeric reference to a policy. However, the policy ID may refer to a non-existing or inactive policy instance in which case it indicates no policy is associated. The Policy ID of value 0 is the default policy.

Load Balancing Policy Rule

A load balancing policy rule governs autonomous load balancing operations. Each rule may be enabled, fully disabled, or disabled for a particular period each day independently of the load balancing group’s enable/disable state. A rule ID value is intended to be a numeric reference to a rule. However, the rule ID may refer to a non-existing or inactive rule instance in which case it indicates no rule is associated. Each rule has an associated type, a method, a threshold, and a weight. These parameters are explained below. There are also steering parameters associated with the rule. (See section Load Balance Rule-based Modem Steering, page 34-30 for more details.) A load balance rule may be referenced by multiple policies.

Load Balancing Policy Rule Type

C4/C4c CMTS Rel. 7.4

There are four types of load balancing rules: •

Static

•

Dynamic

•

Both

•

Bonded

Static Load Balancing of CMs occurs during the initial ranging phase.The first opportunity for load balancing is when a CM initially ranges. During this time, the CM may be requested to move to a different upstream channel. The mechanism used to move modems at this stage is compatible with all CM versions. Dynamic Load Balancing means load balancing is done using the Dynamic Channel Change (DCC) directive and occurs via DCC immediately after registration time and at the macdomain-check intervals. This applies only to DOCSIS 1.1 and later non-bonded modems. Both indicates that the load balancer performs both static load balancing at the initial maintenance ranging time and dynamic load balancing at registration time and at the regular dynamic load balancing intervals. The load balancer does not permit these two types of load balancing to conflict with each other. As a CM first ranges, if it should be moved, then it is given an upstream channel override in the range response message. This CM is marked as “load balanced” so that it will not be asked to move again after it completes registration. (The exception to this case is if the CM is a member of a restricted group and it must move to another channel in that restricted group.) A CM that is moved to a new upstream channel is marked as “load balanced” so that it will not be given an upstream channel override when it ranges on the new channel. Bonded Load Balancing means all of the above in addition to including bonded cable modems as part of the dynamic load balancing process. The caveats are that since bonded modems are DCC'd with init-technique reinit-mac, they are only chosen if no 1.1 or 2.0 modems are available to move, and only the primary DS/US of a bonded modem is moved. NOTE Only the reinit-mac initialization technique is supported for load balancing on bonded CMs.

Load Balancing Policy Rule Method

The C4 CMTS load balancing is based on either CM count or channel utilization. Either of these methods may be provisioned per load balancing group policy. These methods are mutually exclusive for a load balancing group. CM COUNT — This method (defined as method modem in CLI output) periodically compares the number of CMs per channel in a load balancing group. The choice of the CM to be moved is determined by the provisioned values of load balance priority and load balancing policy ID. If these values are over the configured threshold, then a CM is chosen randomly. CHANNEL UTILIZATION — This method (defined as method utilization in CLI output) compares channel utilization of the channels in a load balancing group. Channel utilization for upstreams will be computed by number of minislots used by the map maker for unicast grants divided by the total number of minislots available over a fixed time interval. Channel utilization for downstreams is computed as total bytes sent divided by the total available bandwidth over the measurement interval. The channel pair with the greatest utilization moves a modem to the channel pair with the least utilization. A CM with a lower load balance priority (more likely to be load balanced) will always be chosen to be load balanced over a CM with a higher priority. Load balance priority can be set only with TLV 43.2 in the CM config file.

C4/C4c CMTS Rel. 7.4

Cross-checks are performed to verify that the CM to be moved: •

Has a CM config boot file version level DOCSIS 1.1 or higher

•

Is able to register on the target upstream channel (for example, a DOCSIS 1.1 modem cannot register on a channel provisioned for ATDMA or SCDMA)

•

Has not previously failed to move to the target upstream/downstream channel pair (as shown on the failed list)

•

Has no UGS service flows or any service flows that are dynamically created (e.g. packetcable multimedia gates)

•

Is not under electronic surveillance

•

Is not in multiple receive channel mode (i.e. no service flows bonded across multiple downstreams), unless rule type is bonded

•

Has no dynamic multicast service flows, such as IP Video.

•

Is not a Flexpath modem

•

Is not governed by a load balancing policy that is disabled

•

Is not on the load balancing exclude list

•

Is not in a restricted load balancing group

The CMTS maintains lists of the CMs which have failed to load balance and of the channels to which they failed to move. These lists can be purged by using the command clear cable load-balance state. Purging these lists is recommended when making hardware changes, for example, when replacing CAMs or other modules.

configure cable load-balance rule ... This family of commands controls the type of a load balancing policy rule: method no

Returns the method to the default. (Default is modem.)

method modem

Uses modem count (number of CMs) that are using a channel to determine load.

method utilization Uses the bandwidth utilization of each channel to determine load. threshold

Sets the percentage (1-100%) of load difference between channels that is tolerated before load balancing will be started.

threshold no

Sets the percentage of load difference back to the default (10%).

Relative Weighting

34-8

Weighting allows the operator to configure the relative levels of prioritization on which to base the load balancing decision. One value provides the setting for the load balance rule which determines the relative weighting of the US and DS channels.

ARRIS PROPRIETARY — All Rights Reserved

C4/C4c CMTS Rel. 7.4

The weight types are described in order of precedence: a

equal — Directs the load balancer to use DS and US load equally to determine load balance decisions

b

usOnly — Directs the load balancer to use only the US channel load

c

dsOnly — Directs the load balancer to use only the DS channel load

d

usPlus — Directs the load balancer to double the US channel load over DS channel load. Weighting is 66% US and 33% DS.

e

dsPlus — Directs the load balancer to double the DS channel load over US channel load. Weighting is 66% DS and 33% US.

configure cable load-balance rule channel-weight {equal | US-only | DS-only | US+ | DS+ } [no] This command configures relative weighting of upstream channels versus downstream channels for load balancing decisions.

no

Returns the channel-weight to the default value of "equal”. The show cable load-balance policy and show cable loadbalance channels commands display the load balancing rule’s channel-weight value. These are shown in sample outputs in Show Commands, page 34-17.

Configuring the Number of Modems to Be Checked

You can set the number of modems to be checked for utilization at each load balancing interval. If you set this value low, then high-utilization users are less likely to be moved to a different channel. Setting this value high makes it more likely that high-bandwidth users will be moved more frequently.

configure cable load-balance utilization-modems-to-check x Where x is a value from 1-100. The default is 10. This setting has no effect on load balance groups that are configured to use the modem count method.

Using Multiple Rules

C4/C4c CMTS Rel. 7.4

It is possible to configure a policy with more than one load balancing rule. In such cases the CMTS uses the following algorithm to determine which load balancing rules to follow: •

If one rule is disabled and another is enabled at any given time, the CMTS uses the type, method, and threshold parameters from the rule that is enabled.

•

If all rules are disabled, there is no load balancing.

•

In the case of multiple rules enabled at the same time, the CMTS uses the type, threshold, method, and weight parameters that cause the most active load balancing. Each parameter is chosen independently and may come from one or more enabled rules.

The following is a priority list from highest to lowest: 1 The order of preference for type is: a

bonded

b

both

c

dynamic

d

static

2 The order of preference for method is: a

utilization

b

3 The threshold used is the lowest value. 4 The order of precedence for weight type is:

The cross-MAC Domain dynamic load balancing moves the cable modem assignment from one MAC Domain to a different one based on the conditions of one or more of its upstream or downstream channels. The new MAC Domain will have different US and DS channels because a channel cannot be in more than one MAC Domain.

C4/C4c CMTS Rel. 7.4

The following guidelines apply to the cross-MAC Domain dynamic load balancing feature:

Dynamic Load Balance Intervals

•

Up to four cable-macs residing on the same fiber node are supported.

•

Up to three upstream CAMs and/or three downstream CAMs residing on the same fiber node are supported.

•

The MAC Domains are members of the same cable bundle.

•

General Load Balancing Groups must be configured with the same load balancing policy.

The CMTS implements the dynamic load balancing as a periodic audit. The period between audit runs is configurable by the operator. There are two system parameters for load balancing activation for all restricted and general load balancing groups: •

MAC-domain-check-interval interval between checks for load balancing within a single MAC Domain.

•

across-MAC-domain-check interval interval between checks for load balancing across MAC Domains.

Both of these parameters are specified in seconds. If the interval value is set to zero, then periodic dynamic load balancing is disabled. Zero is the default for the across-MAC-domain-check; 300 seconds is the default for the MAC-domain-check-interval. For normal operations these parameters should not be set below 60 seconds. In special cases requiring rapid load balancing these values may be temporarily set to lower values. For example, when adding new downstream or upstream channels to a system, rapid load balancing can be used to quickly move cable modems to the new channels. When the channels reach balance, these parameters should be set back to a value of 60 seconds or more to avoid excessive cable modem moves between channels during normal operation. At every MAC-domain-check-interval the CMTS analyzes the load on the channels within a MAC Domain using one of the two methods (count or utilization). If needed, it initiates a Dynamic Channel Change (DCC) of a modem from the heaviest loaded channel pair to the lightest. In this way the channels within a single MAC Domain gradually approach being balanced over time without excessive impact on system performance.

configure cable load-balance macdomain-check ... This command configures the intra-MAC-domain load balancing check interval.

Sets the intra-MAC-domain load balancing checking interval. Value is in seconds.

no

Returns intra-MAC-domain checking interval to default value. (Default is 300 seconds.) At the end of each across-MAC-domain-check interval the CMTS analyzes the need for load balancing across MAC Domains. Each CAM reports the load for each of its downstream channels that belong to load balancing groups. If needed, the CMTS directs the MAC Domain channel with the heaviest load to DCC a single modem to the most lightly loaded MAC Domain channel in that load balancing group.

configure cable load-balance across-macdomain-check ... This command configures the cross MAC Domain dynamic load balancing check interval for load balancing groups consisting of channels from all CAMs for release 7.4 and later.

no

Returns intra-MAC-domain checking interval to default value. (Default is 0.)

NOTE Cross MAC Domain dynamic load balancing and intra-MAC-Domain load balancing are independent processes in the CMTS.

Minimal Configuration If no load balancing configuration commands are entered, by default, load balancing would be configured as follows (and shown in the example output below). •

A general group default policy (0) is created.

•

A default rule is created and associated with the general group default policy. It has the following default settings:

•

- The rule is “enabled” - The type is “both” - The method is “modem” - The threshold is “10 percent” - The channel-weight is “equal” - All steering attributes are false - The disable-period is not set. A GLBG is created for each MD-CM-SG

•

Each GLBG is associated with the general group default policy, therefore, each GLBG is enabled.

•

The “init-technique” of the general group default policy is disabled, which in effect, disables periodic load balancing for each of the GLBGs.

The following are additional load balancing default settings: •

The periodic load balancing interval is set to 300 seconds.

•

The periodic cross-MAC-domain/cross-CAM load balancing interval is set to 0 seconds (disabled).

•

The downstream-start-threshold is set to 1 percent.

•

The upstream-start-threshold is set to 1 percent.

•

The failed-list exclude-count is set to 1.

•

The failed-list timeout is set to 0, which implies that modems that fail a DCC will remain on the failed list indefinitely.

If issued with only the us-channel-id parameter but without the downstream frequency identified, this command applies only to a CM staying in the same CMTS. This command moves CMs by re-initing the CM followed by a downstream frequency override and/or an upstream channel override in the range response. It can be used to move all types of modems, including DOCSIS 1.0 modems. Enter the following command to move the CM to different channels: configure cable modem move [downstream-freq ] [us-channel-id ] Where chan is the US DOCSIS channel ID. Range = 1-255.

Failed List Operation

Modems may appear in the load balance failed list multiple times, once for each DS/US channel pair that it has failed to move to. The load balancing software will consider a DS/US channel pair as a valid target for a given modem unless that modem has failed to move to that channel pair the exclude-count (default is 1) number of times. Until the modem has failed the exclude-count number of times for every DS/US channel-pair in the associated fiber-node, the modem will still be considered a candidate for load balancing. Modems can appear on the failed list for a number of reasons including the modem does not handle DCC well, the fiber-node/connectors on the CMTS

are configured incorrectly or there was an RF issue causing the DCCs to fail for a period of time. Following a period of RF issues on a given fibernode, it is recommended that the failed list be cleared to give the load balancing software a larger pool of modems from which to choose so that the load balancing software is more effective. The list can be cleared as needed by support personnel with the command: clear cable load-balance state Aging out Failed Modems — Modems on the failed-to-load-balance list will be aged out when the timeout value is non-zero. configure cable load-balance failed-list timeout x Where x is the number of hours that a failed modem stays on the list. The minimum setting is one hour. The default value of 0 means that the modems will never be removed from this list unless you manually clear the list. It is recommended that this value be set to a value such as 48 to allow for transient DCC issues caused by things such as cable cuts, etc. Time is taken from the CMTS's internal clock. It does not automatically adjust for calendar changes such as daylight savings time. To confirm the aging-out setting, use the following command: show cable load-balance Failed-list exclude-count — By default a modem will only be allowed to fail being moved to a given DS/US channel pair a single time. It has been observed that load balancing is more effective when the default value of 1 is changed to a value like 3. This prevents the failed-list from getting excessively large, which limits the number of modems that are available and may negatively impact the effectiveness of the load balancing software. configure cable load balance failed-list exclude count x

Where x is the number of times that the modem has failed to move to each DS/US channel pair in the load balance group.

If the exclude-count parameter is set to the default value of 1, then the verbose option has no effect on the output of the show command. Exclude Modems from Load Balancing — Modems that continually fail to move to less loaded channels when instructed to do so by a load balancing DCC or should not be DCC'd for other reasons can be excluded from subsequent load balancing attempts by either adding the modem to the exclude-list or by creating a restricted load balance group that is disabled. One way to exclude a modem from load balancing is to add the Organizationally Unique Identifier (OUI) to the exclude-list: configure cable load-balance exclude oui 001596 The other way to exclude a modem from load balancing is to create a restricted load balance group that is disabled and assign modems to that group. Use the following commands to create a restricted load balance group: configure interface cable-mac 1 cable load-balance group 99 configure cable load-balance policy 99 rule 99 configure interface cable-downstream 14/0 cable load-balance group 99 configure interface cable-upstream 1/0.0 cable load-balance group 99 configure interface cable-mac 1 cable load-balance group 99 policy 99 configure interface cable-mac 1 cable load-balance group 99 init-technique disable configure interface cable-mac 1 cable load-balance group 99 enable To add a modem to this group: configure cable load-balance include cm-mac 00.15.96.2a.65.9c mac-mask ff.ff.ff.ff.ff.ff group 99

C4/C4c CMTS Rel. 7.4

Interaction with Older Cable Modems Load balancing uses DCC commands to move Cable Modems after they are registered. DOCSIS 1.0 CMs and their configuration files do not support DCC. These CMs can still be load balanced on upstream channels within a MAC Domain by static load balancing. Static load balancing will move the CMs to a less loaded upstream channel via an upstream channel override as the CMs first range, prior to their registration. Once a DOCSIS 1.0 CM is registered it remains on its upstream channel until it is reset. If you configure a policy for a load balancing group, set the TYPE to BOTH, in order to use static load balancing for DOCSIS 1.0 CMs and Dynamic Load Balancing for DOCSIS 1.1 and later CMs. By default, a load balancing group TYPE is set to BOTH. DOCSIS 1.1 and 2.0 CMs with CM software released prior to 2005 are known to have some difficulties with DCC commands. The following suggestions should maximize the chances for older CMs to successfully move between channels: •

If at all possible, upstream channels within a dynamic load balancing group should have identical modulation profiles and channel width.

•

If using ATDMA or SCDMA channels, dynamic interleaving should be disabled.

•

If moving older CMs running Baseline Privacy Interface (BPI) across MAC Domains, the recommended DCC technique is reinit-mac. Any other technique for moving the CMs should be tested in the lab. Older CMs running BPI are known to have a problem with BPI rekeying after being moved across MAC Domains with initialization techniques other than reinit-mac. When this problem occurs, the DCC succeeds, but the CM cannot send or receive data.

Load Balancing of Bonded Cable Modems There are two types of load balancing that may occur on a bonded cable modem. The first type only affects D3.0 bonded modems. For this type, the CMTS will give the bonded modem a Receive Channel Set (RCS) based on the DS load of the channels at the time the bonded modem is registering. This RCS is sent to the modem in the Registration Response (REGRSP). The CMTS will choose the least loaded DS channels for the RCS, effectively load balancing the primary and all non-primary DS channels of that bonded modem. To enable this type of load balancing, the bonded

C4/C4c CMTS Rel. 7.4

modems only need to be associated with a load balancing group that is enabled. This functionality is effective for balancing the DS channels for bonded modems. The second type of load balancing that can occur to a bonded modem is very similar to the 'dynamic' DCC type of load balancing that occurs for D1.1 and D2.0 modems, except it allows the DCC of bonded modems. This type is effective for both D2.0b and D3.0 bonded modems. By default this is disabled because bonded modems can only be DCC'd with the reinit-mac technique regardless of the init technique configured in the CLI, which is disruptive to end users. Similar to the Dynamic type load balancing, the CMTS will load balance via DCC the bonded modems at periodic intervals. Keep in mind that this will load balance only the primary US and primary DS of the bonded modem. The non-primary DS/US channels of a bonded modem cannot be moved via DCC. This type of load balancing requires the 'bonded' type to be specified in the load balance rule. The CMTS will only choose to move a bonded modem if there are no non-bonded modems that it can move instead. NOTE Cross-MAC Domain movement of both downstream and/or upstream bonded CMs is supported but only with the re-init MAC initialization technique. Load balancing on bonded 3.0 CMs affects only the primary US and DS channels.

Distributing Bonded CMs across Downstreams at Registration Time When a CM sends a bonded registration request and the CM is in an MD-CM-SG that corresponds to an enabled load balance group, the C4 will attempt to assign a Receive Channel Set (RCS) that includes the least loaded downstreams in the MD-CM-SG. The RCS is sent to the modem in the range response prior to registration. This only applies to DOCSIS 3.0 CMs since DOCSIS 2.0b CMs do not support changing their primary DS channel when they register. When assigning the RCS for DOCSIS 3.0 CMs, the CMTS may change both the primary and non-primary downstreams in the RCS sent in the registration response based on load.

Load balancing of the downstreams in the RCS only occurs when all of the following is true: •

DOCSIS 3.0 load balancing is enabled.

•

The modem is a DOCSIS 3.0 modem with Multiple Receive Channel Mode (MRCM) enabled for both the MAC Domain and the modem.

•

There are multiple candidates where: -

Channel sets are of equal size. i.e., same number of downstream in each set. Channel sets both equally satisfy the service flow attributes.

This feature presumes that dynamic bonding groups and dynamic Receive Channel Configurations (RCCs) are enabled. This is because dynamic bonding groups will provide the maximum number of downstreams to choose from when attempting to find the least loaded downstream set for the RCS. Also, this feature is to be used with general, i.e., not restricted, load balancing groups.

Load Balancing Bonded CMs at Regular Intervals At regular intervals, (set by load-balance macdomain-check) the dynamic load balancer will audit the channel load in each load balance group. If the load balance group has its rule type set to bonded, then bonded CMs are considered to be candidates for moving from heavily loaded channels to the lightest loaded channels. Since DCC is used to load balance D3.0 modems, only the primary DS or primary US of the CM will be moved. NOTE Non-bonded DOCSIS 3.0 modems will be treated like DOCSIS 2.0 modems with regard to load balancing.

NOTE Bonded CMs will always be moved using DCC init technique reinit-mac. Multiple rules can be assigned to a load balance policy and a load balance group. If there are multiple rules enabled for a policy, then the load balancer gives priority to rules of type bonded over rules of the other types (static, dynamic, both). This allows an MSO to set up a configuration where a rule of type bonded may be disabled at certain times of the day. For example, they may want to load balance bonded CMs only during the maintenance window, since a DCC of a bonded CM causes it to flap. They may also set up a second rule of type both that is enabled at all times. The net effect is that non-bonded CMs will be load balanced at all times using

the initialization technique assigned to the group, and during the maintenance window bonded CMs will also be considered for load balancing using the reinit-mac init technique. An example of setting up bonded modem load balancing is: configure cable load-balance rule 1 enable configure cable load-balance policy 1 rule 1 configure cable load-balance rule 1 type bonded configure cable load-balance general-group-defaults policy 1 An example of setting up bonded modem load balancing so that it occurs only between 2 a.m. and 4 a.m.: configure cable load-balance rule 1 disable-period start-time 04:00:00 period 22:00:00 The following additional rule can be assigned to the policy so that nonbonded load balancing occurs during the remainder of the day: configure cable load-balance rule 2 enable configure cable load-balance rule 2 type both configure cable load-balance policy 1 rule 2

DCC across MAC Domains Using MIBs This feature provides an interface that supports the manual Dynamic Channel Change (DCC) of CMs across Mac Domains on either separate US CAMs or the same US CAM. NOTE The configure cable modem move command allows for this same functionality and is the preferred method. An MSO can send a DCC command to a specific CM by setting the fields in the docsLoadbal3ChgOverGroup MIB.

This Load Balancing feature supports setting and acting on the following docsLoadBalChgOverGroup values: •

docsLoadbal3ChgOverGroupMacAddress

•

docsLoadbal3ChgOverGroupInitTech

•

docsLoadbal3ChgOverGroupdownFrequency

•

docsLoadbal3ChgOverGroupMdlfIndex

•

docsLoadbal3ChgOverGroupUsChSet

•

docsLoadbal3ChgOverGroupCommit.

The DCC command accepts only a single upstream channel ID, therefore, the docsLoadbal3ChgOverGroupUsChSet MIB can only be set to a single US channel ID. The range is 1-255. The CMTS supports several cross-checks when setting the MIB value, including: •

The Mac Domain IfIndex must exist.

•

A downstream must exist and match the docsLoadbal3ChgOverGroupdownFrquency.

•

The upstream channel ID must exist on the CMTS on the specified Mac Domain.

The command will be rejected with an error message if any of these items are invalid when a ChgOverGroupCommit is attempted. DCC Init Technique

DCC’ing a CM across Mac Domains requires the reinit-mac to successfully accomplish the process. If any other init technique is used, the command will be rejected in Release 7.3 and earlier. When setting the init technique bits in the MIB, refer to the following values: •

0x80 = reinit-mac

•

0x40 = broadcast-ranging

•

0x20 = unicast-ranging

•

0x10 = ranging

•

0x08 = direct

All of the above init techniques are supported for D1.1 and D2.0 cable modems. This applies to both dynamic cross-MAC Domain load balancing as well as load balancing across MAC Domains using MIBs and DCC.

Moving to an SCDMA US Channel

C4/C4c CMTS Rel. 7.4

In the case of modem steering or load balancing a CM to an SCDMA upstream channel, the following apply: •

If the general load balance group specifies either initialization type 0 or 1, then that technique is used as is (no overriding is necessary).

•

If the GLBG specifies an init technique greater than 1 (type 2, 3 or 4), then it will be overridden to be type 1 (broadcast initial ranging).

Bonded CMs always use the reinit-mac initialization technique. Summary of Rules for DCC Init

The following list summarizes the load balancing rules for various types of CMs: •

DOCSIS 1.0 CMs: No DCC is allowed.

•

DOCSIS 1.1 and 2.0 CMs: DCC with all init techniques is supported.

•

DOCSIS 2.0b and 3.0 CMs: CMs are always moved using the reinit-mac technique.

Downstream and Upstream Utilization Start Thresholds Separate load balancing start thresholds are set globally for upstream and downstream channels. They are used to prevent the load balancing feature from moving CMs when channels are lightly loaded. An MSO can use start thresholds to define when channel loading is great enough to begin moving modems from channels that have exceeded the threshold to lightly loaded channels. If no channels in the load balance group exceed either start threshold, the load balancer does not attempt to balance the channels. By default, the minimum start thresholds are set to 1%, which means they have will have no effect unless explicitly configured to be a higher value. For example, an MSO might set this minimum threshold to a value of 30%, based on the reasoning that if all the channels in a load balance group are under 30% loaded, it is not necessary for the channels to be in balance. In load balancing the start threshold is not the same as the rule threshold. The start threshold determines when load balancing is allowed to begin; the rule threshold defines how much of a difference between the highest and least loaded channels is acceptable. If the rule threshold is set to 10%, and the most heavily loaded channel in the group is 50% full and the least loaded channel is 40% full, then no CMs will be moved. Once the heaviest channel becomes 51% full or the lightest channel becomes 39%

full, then load balancing will start to move modems, assuming that the start threshold has been exceeded. Load balancing occurs only when the rule threshold is exceeded. By default, the rule threshold is set to 10%. Table 34-1: Effect of Start and Rule Thresholds on Load Balancing If threshold settings are

When the load balancing method is set to utilization, it is obvious to see if the rule threshold (a percentage) is exceeded because the load on each channel is a percentage. However, when the load balancing method is set to modem, it's not as obvious because the DS load and US load for each channel is the count of the modems on each channel, not a percentage. To determine if the rule threshold is exceeded, the rule threshold is converted to a count for both the DS and US. This is done by multiplying the rule threshold (as a percentage) with the DS load of the heaviest loaded channel pair, and by multiplying the rule threshold (as a percentage) with the US load of the loaded heaviest channel pair. For example, if the loaded heaviest channel pair has 50 modems on the DS and 40 modems on the US, for a rule threshold of 10%, the count threshold is 5 for the DS and 4 for the US. In this case, load balancing would continue to occur when the difference in load between the heaviest loaded channel pair and the lightest channel pair was greater than 5 for the DS or greater than 4 for the US. To configure the thresholds used as an example in Table 34-1, use the following commands: configure cable load-balance downstream-start-threshold 30 configure cable load-balance upstream-start-threshold 30 To verify your settings, use the following show command: show cable load-balance Load Balance : Enabled Mac Domain Check (sec) : 30 Across Mac Domain Check (sec) : 0 Downstream Start Threshold (% utilization) : 30

NOTE If the start thresholds for downstream channels are exceeded, the load balancer will move CMs to balance the downstream even if the start thresholds for that downstream’s upstream channels have not been exceeded. And if the thresholds for an upstream channel have been exceeded, the load balancer will move modems to achieve upstream balancing even if the downstream channel thresholds have not been exceeded.

Load Balance Rule-based Modem Steering You can configure the Modem Steering feature to move DOCSIS 2.0 or 3.0 modems, if they register on a TDMA or TDMA/ATDMA (T-A) channel, to the least loaded ATMDA or SCDMA channel. The move takes place either immediately following registration or periodically. DOCSIS 2.0 modems use the init-technique which is associated with their load balance group. Bonded modems use the reinit-mac technique. Modem Steering with Mixed TDMA/ATDMA Channel Support

The modem steering feature with mixed mode channels supports modem steering from either a TDMA or T-A channel to an ATDMA or SCDMA channel as long as the load balancing policy is set to steering. NOTE This applies to both registration and periodic modem steering.

NOTE Modem steering only moves modems within a cable-mac.

CAUTION

Caution should be used when enabling the DOCSIS 2.0 modem steering feature as some modems have issues successfully re-registering if they receive a DCC immediately following their initial registration. The C4 CMTS provides for intra- and inter-MAC Domain load balancing among the TDMA, T-A, ATDMA, and SCDMA upstream channel types, depending on the modem version as described below. If the configuration is such that the modem steering flags are set to enable steering on D2.0 devices but set to disable D3.0 modem steering, then the following applies: •

D3.0 cable modems (CMs) are load balanced across the set of available TDMA, T-A, ATDMA, and SCDMA channels.

•

D2.0 CMs are steered to ATDMA or SCDMA channels.

•

D2.0 CMs are load balanced across the set of available ATDMA and SCDMA channels.

•

D1.1 and D1.0 modems are load balanced across the set of available TDMA and T-A channels.

If the modem steering flags are set to enable both D2.0 and D3.0 CMs, load balancing is supported as follows: •

D2.0 and D3.0 CMs are load balanced across ATDMA and SCDMA channels.

•

D2.0 and D3.0 CMs are steered to ATDMA and SCDMA channels.

•

D1.1 and D1.0 CMs are load balanced among remaining TDMA and TA upstream channels.

NOTE When steering a modem either to or from an Upstream SCDMA channel, the C4 CMTS will use init-technique broadcast ranging regardless of the init-technique specified by the CLI. The exception is if the init-technique is reinit-mac in which case, reinit-mac will be used. Balancing D2.0 Modems While Steering D3.0 Devices

This load balancing enhancement allows for utilizing bandwidth capabilities of the ATDMA and SCDMA channels for D3.0 modems while providing even distribution options for the D2.0 CMs across the remaining TDMA and T-A channel types. NOTE This applies to both registration and periodic modem steering.

This enhancement supports configurations where modem steering flags are set to enable steering on D3.0 devices but set to disable D2.0 device steering. The C4 CMTS provides for intra- and inter-MAC Domain load balancing among the TDMA, T-A, ATDMA, and SCDMA upstream channel types, depending on the modem version. The following configurations apply: •

D2.0 CMs are inter- and intra-MAC Domain load balanced across available TDMA, T-A, ATDMA, and SCDMA channels.

•

D1.1 and D1.0 CMs are load balanced across available TDMA and T-A channels.

•

D3.0 CMs are steered to ATDMA and SCDMA channels.

•

D3.0 CMs are load balanced across available ATDMA and SCDMA channels.

NOTE Cross-checks verify that the CM to be moved has a CM config boot file version level greater than DOCSIS 1.0. Use the following commands to configure rule-based modem steering: configure cable load-balance rule x registration-steeringD2 configure cable load-balance rule x registration-steeringD3 configure cable load-balance rule x periodic-steeringD2 configure cable load-balance rule x periodic-steeringD3 Where x is the number of the rule. When enabling either registration or periodic D3.0 modem steering on the C4 CMTS in conjunction with USCB, it is recommended that any D2.0 capable US channels (ATDMA/SCDMA) in the mac-domain be configured such that they are the lowest numbered channels in the cable-mac. This applies to configurations in which the cable-mac(s) configured for the D3.0 modems contain a mix of non-D2.0 (TDMA & T-A) and D2.0 (ATDMA & SCDMA) channels and the number of upstreams configured in the cablemac is greater than the number of US channels being bonded. This is done to help ensure that the non-primary US channels of the bonded modem will end up on D2.0 capable channels. The Transmit Channel Set (TCS) calculated by the CMTS (if all US channels have acceptable US power levels) is chosen from lowest to highest channel-id. Since load balancing of bonded modems is limited to the DCC of the primary US and the primary DS, non-primary US channels of the

C4/C4c CMTS Rel. 7.4

Service-type Modem Steering Service-type modem steering is designed to steer modems to specific interfaces. Service-type modem steering works in conjunction with the Load Balancing feature in the CMTS. The operator assigns a particular service-type ID to the modems to be steered and to the restricted load balancing groups containing the specific interfaces to which he/she wants those modems assigned. The service-type ID refers to the type of cable data service. The desired service-type ID is assigned to a modem either by associating its MAC address or its Organization Unique Identifier (OUI) with a particular service-type ID. Another way is by adding a Type-Length-Value (TLV) representing the service type to the modem’s config file. If there is a match between the service-type ID of the restricted load balancing group and the service-type ID defined in the modem’s config file or associated with its MAC address or OUI, then the CMTS assigns that modem to one or more upstream/ downstream pairs of that restricted load balancing group as soon as the modem registers. NOTE Service-type modem steering is supported by the 12U, 24U, 16D, and XD CAMs (24D and 32D). The following factors will prevent a cable modem from responding to the Service-type modem steering feature: •

Dynamic Load Balancing is disabled at the CMTS. By default load balancing is enabled on the CMTS. To turn it off, use configure cable load-balance enable no.

•

34-34

Dynamic Load Balancing is disabled for the load balancing group to which the modem belongs.

C4/C4c CMTS Rel. 7.4

By default a load balance group is enabled when created. To disable, use configure interface cable-mac x cable load-balance group y enable no.

Procedure 34-1

•

The cable modem has an OUI that is on the list of OUIs excluded from load balancing

•

The cable modem is a FlexPath modem. FlexPath has its own method for directing modems.

•

The cable modem has a policy that is disabled or is set for static load balancing only

•

The restricted load balance group has a policy that is disabled or is set to static load balancing only

•

The cable modem is on the failed list and has failed to move to all the channels in its restricted load balance group.

Example of Service-type Modem Steering Configuration The following procedure is an example of how to configure and enable the Service-type modem steering feature. 1 Create a restricted group and apply the service-type ID to that group:

configure interface cable-mac 1 cable load-balance group 100 configure interface cable-mac 1 cable load-balance group 100 enable configure interface cable-mac 1 cable load-balance group 100 init-technique ranging configure interface cable-mac 1 cable load-balance group 100 service-type "abc" In this example the restricted load balance group is given the number 100, the initialization technique is ranging, and the service type is named abc. NOTE If no init-technique is set then the default is broadcast-ranging except for the case of 2.0B or 3.0 CMs which must get an initialization technique of reinit-mac. 2 Assign the interfaces to the restricted load balance group: configure interface cable-downstream 14/0 cable load-balance group 100 configure interface cable-downstream 14/1 cable load-balance group 100 configure interface cable-downstream 14/2 cable load-balance group 100

SCM Packet Throttling Packet throttling prevents or limits the impact of denial of service (DoS) attacks or of defective cable modems or CPEs that generate excessive numbers of DHCP or ARP packets. The CMTS has the ability to throttle the rate at which packets are forwarded to the SCM modules. Packet throttling for the SCM is indiscriminate: you can throttle the overall packet rate but not individual packet types. To configure protocol throttling for the SCM, use the following command: configure slot 19 proto-throttle-rate Where

RCM Protocol Policing This feature is also known as Improved Denial-of-Service Attack Protection. This feature allows the CMTS to select and police packets destined for the RCM processor according to packet protocol type. By selectively throttling undesired protocol packets, the CMTS can continue to function as a router during malicious attacks. This alleviates the impact of various denial of service (DoS) attacks, because critical packets continue to be processed by the CMTS. Use the following command to set global or protocol-specific packet throttling for the RCM: configure slot proto-throttle-rate {arp|bgp|cops|dhcp|icmp|igmp|isis| ospf|ospfv3|pim|rip|snmp|snmp-cm|telnet|tftp|other} Where

slot number = packets per second =

17 or 18 for the RCM a valid range of 0-65535 0 = “allow none”.

If none of the optional protocol types are specified, the command serves to set the global throttle rate (total of all packet types) allowed through the RCM. Use the following command to display protocol-throttling settings and counts: show proto-throttle-rate The following is a example of the system output: Protocol Throttle Rates ----------------------RCM global packet rate:

35 Packet Throttling

C4/C4c CMTS Rel. 8.0.7

Upstream Cable Protocol Throttling This feature is also called subscriber-side throttling or DHCP/ARP Throttling. Upstream channels on the cable or subscriber side of the network can be inundated by DHCP and ARP packets coming from modems and customer-premise equipment (CPE). These DHCP or ARP requests may come from malicious users, viruses, spyware, or faulty equipment. The IPv6 Upstream Cable Protocol Throttling feature throttles IPv6 DHCPv6 packets in the same way that IPv4 DHCP packets are throttled. It throttles IPv6 ND (Neighbor Discovery) packets (Neighbor Solicitation, Router Solicitation, Router Advertisement, Redirect and Neighbor Advertisement) in the same way that IPv4 ARP packets (ARP Request and ARP reply) were throttled in Release 7.3 and earlier. The C4/C4c CMTS throttles all DHCPv4 and DHCPv6 packets the same based on their leaky bucket settings. The CMTS treats all of the ARP Request packets, ARP Reply packets, ND Neighbor Solicitation packets, ND Neighbor Advertisement packets, Router Solicitation packets, Router Redirect packets, and Router Advertisement packets the same, throttling them collectively using the ARP/ND leaky bucket settings. Once configured, the CMTS throttles upstream cable-side IPv6 packets based on their MAC addresses. The max-burst parameter defines the number of packets that are allowed before throttling begins. The rate of throttling is defined by the interval parameter. Once the max-burst limit is reached for a given MAC address, throttling begins. Packets for that MAC address are dropped until one or more intervals have passed. Each time an interval passes the CMTS lowers the packet counter by one, allowing an additional packet for that MAC address to pass through. Thus, once a source MAC has reached the max-burst limit, the CMTS allows it only one packet per interval. IPv6 Neighborhood Discovery (ND) is a set of protocol messages (rfc 2461) and processes that determine relationships between neighboring nodes. There are five types of ND packets that are throttled by this feature: •

Router Solicitation (RS — type 133)

•

Router Advertisement (RA — type 134)

•

ND neighbor solicitation (type 135)

•

ND neighbor advertisement (type 136)

•

Redirect (type 137)

Type is an option that is formatted in the type-length-variable (TLV) format.

IPv6 DHCPv6 (rfc3351) enables DHCP servers to pass configuration parameters to IPv6 nodes. There are five types of DHCPv6 server messages that are throttled by this feature: •

Solicit (type 1)

•

Advertise (type 2)

•

Request (type 3)

•

Reply (type 4)

•

Renew (type 5)

Type is an option that is formatted in the type-length-variable (TLV) format. The ARP Neighbor Discovery (ND) Abuse Detection feature provides a means to monitor the first 32 devices (i.e. MAC addresses) that are ARP and/or ND throttled on an interface, and count the number of ARP request and IPv6ND Neighbor Solicitation packets, or ARP reply packets and IPv6 ND Neighbor Advertisements that are dropped due to throttling for the devices. There are seven types of ARP/ND packets that are monitored and throttled by this feature. Four are types of request packets and three are replies. ARP/ND requests that this feature throttles: •

ARP request (Ether Type 0x0806)

•

IPv6 Router Solicitation (RS – type 133)

•

IPv6 Neighbor Solicitation (type 135)

•

IPv6 Redirect (type 137)

ARP/ND replies that this feature throttles: •

Arp reply (Ether Type 0x0806)

•

IPv6 Router Advertisement (type 134)

•

IPv6 Neighbor Advertisement (type 135)

NOTE This feature is fully supported by the 12U/24U CAM. ND Abuse Detection is only available on the 12U/24U CAM. The operator can enable throttling for ND packets even if IPv4 ARP throttling is disabled. In the same way, he or she can enable DHCP or DHCPv6 throttling or both.

CMTS Configuration

Use the following command to enable [disable] throttling of cable-side IPv4 DHCP or ARP requests: configure cable proto-throttle [no] Use the following command to enable [disable] throttling of cable-side IPv6 DHCP packets: configure cable proto-throttle dhcpv6 [no] Use the following command to enable [disable] throttling of cable-side Neighbor Discovery (ND) packets: configure cable proto-throttle nd [no] Use the following commands to provision the degree of throttling: configure cable proto-throttle [interval ] | [max-burst ] Where: interval is a period of time from 1-10 seconds; the default is 5. This parameter defines the rate of transmission after throttling begins. Throttling begins once the max-burst limit has been exceeded. If the interval is set to five, then after throttling begins, no more than one packet can be sent every five seconds. max-burst defines the maximum number of ARP or DHCP packets allowed from that source per second. The default is 10, which means that up to ten packets per second can be sent before throttling begins. Once configured, the CMTS throttles DHCP or ARP packets on the basis of their MAC address. The max-burst parameter defines the number of packets that are allowed per second before throttling begins. Raising the max-burst increases the number of DHCP or ARP packets allowed per second for a given MAC address before throttling begins. The rate of throttling is defined by the interval parameter. Raising the interval reduces the rate of accepted packets for a given MAC address. Each DHCP/ARP packet increments the counter towards the max-burst limit. Once the max-burst limit is reached for a given MAC address, throttling begins. Each time an interval passes the CMTS lowers the counter by one, allowing an additional packet from that MAC address to pass through. Thus, once the CM or CPE has reached the max-burst limit, it is allowed one packet per interval. If, for example, the max-burst is set to five, and the CM or CPE after reaching its limit waits five intervals without sending any DHCP/ARP packets, then it is allowed up to five requests in a burst before its DHCP or ARP packets are again throttled.

ARP/ND Abuse Counts This feature is an extension of DHCP/ARP Throttling; it provides a means of controlling CMs or CPEs that are generating excessive DHCP, ARP, or Neighbor Discovery packets. DHCP/ARP Throttling must be enabled for ARP/ND Abuse Counts to function. This feature monitors the first 32 devices (i.e., MAC addresses) subject to ARP/ND request throttling on an interface plus the first 32 devices subject to ARP/ND reply throttling on an interface. It then counts the number of ARP/ND request or reply packets dropped due to throttling of those devices. Two new CLI show commands are provided to display the number of ARP/ND request and ARP/ND reply packets dropped respectively for the devices that are being monitored and counted. These CLI commands provide the option to display only those devices that have dropped more than a specified minimum number of ARP/ND packets. Additional CLI commands are available to clear the ARP/ND abuse counts and the throttling history. Once enabled, this feature maintains lists of up to 32 MAC addresses per ARP/ND packet type being dropped because of throttling. Each interface list contains counts for the first 32 MAC addresses that get throttled. If a given MAC address becomes inactive, it is dropped from the list and replaced by the next MAC to experience dropped packets due to throttling. ARP/ND abuse counts do not persist across a CAM sparing event, but do persist after a Control Complex side switch. CLI Commands

Cable-side proto-throttling must be enabled in order to activate ARP/ND Abuse Counts. Cable-side throttling is enabled using the following command: configure cable proto-throttle arp

The no form of the command disables Cable-side proto-throttling as well as ARP Abuse Counts: configure no cable proto-throttle arp Use the following commands to show the number of ARP requests and replies that are throttled: show cable proto-throttle arp-nd-requests-throttled [] show cable proto-throttle arp-nd-replies-throttled []

Token Bucket 3.0: Traffic Shaping on 16D/XD CAMs Overview

With the rapid convergence of different types of Internet traffic flows (voice, video, data, gaming, streaming media, etc.), the various forms of Quality of Service (QoS) mechanisms are being called upon to better manage the bandwidth that is shared by these various traffic flows. Proper application of QoS is essential if statistical multiplexing is employed in the network. Statistical multiplexing permits X subscribers (each requiring a bandwidth of W) to share a single channel providing a total bandwidth T, even if T < XW. On average, this is possible due to the fact that many subscribers are idle for some fraction of their operating time. However, in a system that capitalizes on statistical multiplexing, the total bandwidth converging on a link may periodically exceed the total bandwidth T that can be supported by the link. Under these overload conditions, QoS mechanisms must make decisions about which packets to drop, which packets to route, and what order to use when routing those successful packets.

Traffic Shaping versus Traffic Policing

Currently, the CMTS uses Weighted Random Early Detection (WRED), a congestion avoidance mechanism, along with policing to decide which packets to drop. Another QoS mechanism is traffic shaping. In general, traffic shaping and traffic policing both accomplish very similar goals. Both mechanisms change the handling of packet streams in a particular service flow to better match the service for which the customer subscribed. However, the two mechanisms accomplish this task in slightly different ways. Traffic shaping intelligently delays packets to slow down the effective packet transmission rate, while traffic policing intelligently drops packets. When traffic policing drops TCP packets, for example, this triggers the TCP congestion control algorithm and causes the source to throttle back the transmission rate. In order to maximize throughput, a large burst size is needed by policing in order to reduce the frequency of dropped packets. As the desired bandwidth is made larger and larger, the burst size must also increase. Larger burst sizes result in longer periods of time when the transmission rate for a flow is not limited, producing undesirable interactions with other service flows. Downstream traffic shaping helps to avoid this problem and accommodates a larger range of desired bandwidths. In addition, a two-tiered shaping mechanism is desirable for shaping to different rates before and after the DOCSIS burst is consumed. Traffic shaping temporarily stores packets in buffers in such a way that packets on different flows can be transmitted out of order while maintaining packet order within a flow. Buffers are not reused until they have transmitted or dropped their packets. Policing is done in hardware in the CMTS. The policing engine determines whether a packet is nonconforming and whether shaping is enabled for the flow carrying that packet. Instead of dropping the non-conforming packet, the policing block

calculates how long the packet must be delayed to make it conform. A new shaper block is implemented immediately before the output queue. When the shaper receives a packet, it places it into a time-bin in a calendar queue scheduler, which releases the packet upon completion of the delay that was calculated by the policing block. NOTE Packets arriving from the fabric for PacketCable voice and UGS flows are not shaped. They are placed in a separate queue and are serviced in a strict priority manner before the calendar queue packets. The shaping feature gives preference to PacketCable voice and UGS flows over all other traffic. No other prioritizing is done by the CAM when shaping is enabled. The CAM does not implement any new dropping mechanisms, such as WRED. Policing calculations are still the primary method of limiting bandwidth on individual flows, and the back pressure mechanism of the Router Control Module (RCM) fabric is still used to trigger WRED in the fabric for congestion control and Tmin rate enforcement. In order to implement a “Power Burst” function, the policer uses a dual leaky bucket mechanism. The first leaky bucket uses the DOCSIS Tmax and burst size. The second leaky bucket limits the transmission rate during the period that packets conform to the first leaky bucket, rather than letting a user use the full bandwidth of the link. The second leaky bucket uses a new parameter named Tpeak and has a burst size of 0. A delay value is calculated for each leaky bucket; the larger value is used to delay packets. The CMTS implementation of this feature can be summarized as follows:

Enabling Traffic Shaping

•

Traffic shaping applies only to downstream traffic.

•

Packets that must be held more than two seconds in order to conform to the shaping norms are dropped.

•

Disabling policing on the CMTS also disables traffic shaping on the CAM because policing determines whether a flow is conforming or not.

•

Traffic shaping does not affect PacketCable voice and UGS packets.

To enable traffic shaping on the 16D/XD CAMs, use the following command: configure interface cable-downstream cable rate-limit token-bucket [shaping] Where: slot MAC

shaping Disabling Traffic Shaping

(Optional) Sets the MIB to enable traffic shaping.

To disable traffic shaping, use the following commands: For a 16D/XD CAM: configure interface cable-downstream cable rate-limit token-bucket no Use the following command to set the peak traffic rate for DOCSIS 1.0 cable modems that have been mapped to a DOCSIS 1.1 Class of Service. See the configure cos-mapping command in the CLI Command Reference chapter of the user documentation for more information. configure cos-mapping down-peak-traffic-rate Use the following command to set the peak traffic rate for DOCSIS 1.1 modems assigned to a particular service class (qos-sc = Quality of Service — Service Class Name): configure qos-sc name peak-tr-rate NOTE A peak traffic rate of zero means that peak traffic rate is not utilized. A peak traffic rate with a value less than Tmax for a given flow indicates that the peak traffic rate is limited to the Tmax for that flow.

Upstream Power Boost Cap The Upstream Power Boost feature enables support for upstream Peak Traffic Rate and is similar to the downstream functionality that is supported. Traffic is limited to the peak rate (Tpeak) while a modem is bursting beyond the maximum rate (Tmax). The Tpeak rate is a value greater than the Tmax rate. Once the specified number of bytes have been consumed at the higher rate, the traffic is then throttled back to the Tmax rate. Use the following command to globally enable the Peak Traffic Rate service flow for upstream service flows: configure [no] cable peak-tr-rate-upstream Outputs from the test cm sf and show cable modem qos verbose commands provide both downstream and upstream service flow information.

Upstream Tpeak can be configured via Service Class Name or by explicitly setting it in the modem’s config file (TLV 24.27). To configure Tpeak using service class name: configure qos-sc name dir 2 peak-tr-rate 5000000 configure qos-sc name max-tr-burst 40000000 configure qos-sc name peak-tr-rate 10000000 This command sets the Tpeak for the SCN. When modems register, they get the Tpeak from the CMTS. Be sure to set the Tpeak value larger than the value of the upstream TMAX.

Overview An ACL, or Access Control List, is an indexed, ordered list of entries. It classifies packets based on criteria such as Source IP, Destination IP, Application port for the IPv4 protocol type. Beginning with Release 7.3, IPv6 ACLs are supported with entries created using the Source IP only. Each entry in the list contains a user-configured set of evaluation criteria and either a permit or deny statement. When a packet is classified by an ACL, the fields in its header are compared one by one with the entries in the ACL, starting with the entry with the lowest index value. When a match is found, the comparison process is stopped and the packet is either permitted to continue or denied (dropped) according to the action specified in the ACL. The use of ACLs within the CMTS, and within any router for that matter, is considered a fundamental capability. ACLs are used in conjunction with

one or more ACL applications. It is the ACL application that initiates a packet classification search in a particular ACL and takes action on the packet based on whether the matched ACL entry was a permit or deny. For example, the data plane filter ACL application classifies packets and either transmits them (permit action) or drops them (deny action). It is important to note that, depending on the nature of the ACL application, implementation is provided either within the hardware-based data plane infrastructure, or within the software-based control plane. Note that there are two applications that can be configured to reference an ACL for filtering purposes on the Router Control Module (RCM) data plane. These are described in more detail in this chapter and include: •

Data Plan Filter ACLs

•

SCM Access ACLs

In Release 7.x, the CMTS relies on the RCM to provide generic support for Data Plane Filter ACLs on all Ethernet and CAM interfaces. In addition, the CMTS enables a user to enter a command to display the number of times each ACL entry was matched. The CMTS supports IPv4 standard access lists, which have a range of 1-99. Extended access lists are also supported for IPv4 but not for IPv6. These lists have a range of 100-199. The CMTS supports a total of 2048 access list entries and up to 1024 entries per access list. Determining the maximum number of ACL entries that the Data Plane can hold is notably affected by those created using the range keyword. Entries created with a range take up more physical space than those created without ranges. NOTE IPv6 ACLs are limited to include entries with Source IP only. The CMTS does not support IPv6 ACL entries with any other match criteria. The C4 CMTS does not support extended IPv6 ACLs. IPv6 ACLs are assigned an access list name rather than a number by the operator. A number from 200-399 is automatically generated internally. CLI Commands

This section lists some of the CLI commands that support IPv4 and IPv6 Access Control Lists.

For IPv4: For IPv4 standard ACLs, the access list ID number must be in the range of 1-99 with filtering based on source IP address only.

PacketCable requires that the maximum interval between consecutive attempts to synchronize the CMTS local time of day clock must not exceed one hour. Therefore, NTP.MAXPOLL must not exceed 11 (that is 211 or 2048 seconds, which equals approximately 34 minutes). The CLI command configure ntp maxpoll has a default value of 7. Also, the new CLI command configure ntp minpoll sets the default minimum polling interval in the same way, where minpoll is strictly less than or equal to maxpoll. 4 Configure the time zone: When no parameter is given (or invalid input is detected), this command enters interactive mode. In interactive mode, a list of available canonical time zone (TZ) names is displayed based on a given country name or ISO3166 country code.

Secure NTP NTPv4 provides a mechanism for optional authentication of NTP messages. The PacketCable standard does not require the CMTS to support this mechanism, but some MSOs do require NTPv4 functionality including authentication. The following CLI commands control whether NTP authentication mode is active or disabled: configure ntp authentication configure ntp no authentication The default mode for authentication is enabled when configured by the configure ntp server command. When NTP authentication mode is disabled, all client key configurations are ignored. NTPv4 symmetric key authentication is based on a shared secret — the key — that is used to create a secure hash of the contents of an NTP message using the MD5 message digest method. The MD5 secure hash ensures that the NTP message was created by an authorized client or server and that no other entity has modified it in transit. Note that the contents of an authenticated NTP message are not encrypted and may be readily inspected; only the MD5 secure hash checksum is encrypted using the shared secret. NTPv4 provides for both symmetric key and public key server or peer authentication methods. However, the CMTS only supports the symmetric key MD5 secure hash authentication method. Use the following CLI command to install the symmetric key strings (aka shared secrets) into the local NTP authentication-key database: configure ntp authentication-key md5 where: =

key identifier or ID, which must be an integer. Range = 1-4,294,967,295 (232-1) 0 = no authentication. = authentication key, an ASCII string 1-16 characters long. Any existing ASCII key string for the given key ID will be replaced when this command is executed. Use the no form of the command to remove a key ID and its associated string.

On the CMTS, NTP authentication key strings may be 1 to 16 null-terminated 7-bit ASCII characters excluding ‘ ’ (space), ‘#’ (pound), ‘\t’ (tab), ‘\n’ (line feed), and ‘\0’ (null). Both the client and server must agree on an acceptable key ID and ASCII key string pair. The authentication-key database is indexed by key ID. It must not be shared with any other application in the CMTS. The NTP symmetric key strings are associated with key identifiers used to organize a local database of NTP authentication key strings. Note that the key identifier is also transmitted with the NTP messages so that the client and server can locate the appropriate local key string that encrypts or decrypts the secure hash. Therefore, the client and server both have to agree on a common key ID and a common key string for that key ID. The CLI command configure ntp server uses the key parameter to select the pre-defined ASCII key string from the NTP authentication key database that is used when transmitting authenticated NTP messages between the client and the target server. Examples of command syntax: configure ntp authentication-key 33 md5 KeyString1234567 configure ntp server 10.10.10.10 key 33 configure ntp authentication-key 55 md5 aShortKey configure ntp no authentication-key 55

Commands for Adding Service Class Names

Service Class Names (SCNs) are names that serve as handles for Quality of Service (QoS) parameter sets which can be used to simplify configuration. SCNs identify the QoS parameter sets that are stored in the CMTS. The SCNs are referenced by configuration files when defining service flows. Service Flows (SFs) contain classifiers which determine which packets are included in the SF. The QoS parameter set determines how the packets in the SF are treated. NOTE If there are parameters defined in the config file but also defined in an SCN referenced by that config file, the config file parameters override those found in the SCN. If you define an SCN in a config file but do not define it on the CMTS, you will receive an error and registration will be denied. The config files use this information as part of setting up the service flows that govern the levels of service awarded to cable modems. Service Class Names are intended to be visible to external Operations Support Systems (OSSs). They impact billing operations because they identify SF counters that are used in the MIBs and in the billing records. From a subscriber’s perspective, service classes refer to different levels of service, each with minimum and maximum guaranteed data rates, priori-

ties, and billing rates. A Multiple System Operator (MSO) might choose to offer its subscribers three classes of service and call them, for example, gold, silver, and bronze. Subscribers opting for Gold Service would pay a premium and would be given priority over others. They would benefit from higher bandwidth even during peak access times. Bronze subscribers would pay a minimum rate. Their upstream and downstream rates would be much lower. Silver would be fine for most subscribers, but even Bronze would be much faster and more reliable than dial-up service. NOTE The service class names used in this section are provided as an example only. The MSO may name and configure service class names according to their preference or standard. An SCN is an ASCII string associated with a predefined set of QoS parameters provisioned in the CMTS. The SCN is named in the configuration file. When a cable modem registers, its configuration file causes a service flow to be created using the QoS parameters defined by its SCN. A Service Class Name: •

Enables billing and other OSSs to distinguish service flows by SCN

•

Simplifies the CM configuration file

•

Simplifies the TFTP configuration file

•

Allows higher-layer applications to create a service flow by Service Class Name; these SCNs typically correspond to advertised levels of subscriber service

•

Has a maximum length of 15 characters and is case-sensitive

•

Cannot include spaces unless the name is enclosed in quotation marks (e.g., “Gold Service”).

The Service Class Name is expanded to its defined set of QoS parameters at the time the CMTS successfully admits the service flow. The QoS MIB defines the parameters listed in Table 40-2, QoS Parameters Included in a Service Class Name, on page 40-4. For greater detail on these parameters, refer to CableLabs’ Radio Frequency Interface Specification, SP-RFIv1.1I07-010829, Section 8 and Appendix C. NOTE Typically SCNs are configured using CLI, but they may also be configured in the CMTS via SNMP using a CM management system. This CM management system would define SCNs and define CM configurations as part of a service-level definition process.

SCN Example

The following examples illustrate scenarios in which service class names are assigned into tiered services – for example Gold, Silver and Bronze. Gold Example — This service class may be structured as follows: •

GoldUp—Scheduling Type = 7 (BE), Traffic Priority = 5, a high-priority flow, Maximum Traffic Rate = 192

•

GoldDown—Scheduling Type = 7 (BE), Traffic Priority = 5, a highpriority flow, Maximum Traffic Rate = 1024

Silver Example — This service class may be structured as follows: •

SilverUp—Scheduling Type = 7 (BE), Traffic Priority = 3, a mediumpriority flow, Maximum Traffic Rate = 128

•

SilverDown—Scheduling Type = 7 (BE), Traffic Priority = 3, a mediumpriority flow, Maximum Traffic Rate = 512

Bronze Example — This service class may be structured as follows:

Service Class Examples

•

BronzeUp—Scheduling Type = 7 (BE), Traffic Priority = 1, a lowpriority flow, Maximum Traffic Rate = 64

•

BronzeDown—Scheduling Type = 7 = (BE), Traffic Priority = 1, a lowpriority flow, Maximum Traffic Rate = 256

Table 40-1 compares typical throughputs of sample service classes. Each advertised subscriber service should have a corresponding SCN. These SCNs are called on by the configuration files used to register CMs and by the CMTS to build SFs for subscribers.

Table 40-2: QoS Parameters Included in a Service Class Name Parameter

Keyword Syntax

Purpose

All Flows ServiceClassName (SCN)

name

A predefined Quality of Service that is applied to cable modems by a configuration file and used to encode a Service Flow according to the parameter values found in the SCN. This name is case sensitive; maximum length = 15 characters.

Priority

[priority ]

Allows service flows to be given priority for delay and buffering. The CMTS uses this field to assign traffic priorities, which are implemented using a queuing system.

MaxTrafficRate

[max-tr-rate ]

This parameter is the rate parameter R of a token-bucket-based rate limit for packets. R is expressed in bits per second. This rate expresses an upper boundary, not a guarantee that the rate is available.

MaxTrafficBurst

[max-tr-burst ] Specifies the token bucket size B (in bytes) for this Service Flow.

MinReservedRate

[min-res-rate ]

Specifies the minimum rate, in bits/sec, reserved for this Service Flow. If CM requests less bandwidth than this minimum, the CMTS may reallocate the excess.

MinReservedPkt

[min-res-pkt ]

Specifies an assumed minimum packet size (in bytes) for which the Minimum Reserved Traffic Rate will be provided.

ActiveTimeout

Specifies the maximum duration resources remain unused on an active Service Flow. If [active-tmout ] there is no activity on the Service Flow within this time interval, the CMTS MUST change the active and admitted QoS Parameter Sets to null.

AdmittedTimeout Direction

[adm-tmout ]

Specifies the duration that the CMTS MUST hold resources for a Service Flow’s Admitted QoS Parameter Set while they are in excess of its Active QoS Parameter Set. Indicates direction: 1 = downstream 2 = upstream

dir

Upstream Flow Only Parameters MaxConcatBurst

40-4

[max-burst ]

Specifies the maximum concatenated burst (in bytes) which a Service Flow is allowed. This parameter is calculated from the FC byte of the Concatenation MAC Header to the last CRC in the concatenated MAC frame.

[grant-jitter ]

Specifies the maximum amount of time (in microseconds) that the transmission opportunities may be delayed from the nominal periodic schedule for this Service Flow. Required for UGS and UGS/AD

[grants-per-int ]

For UGS, the value of this parameter indicates the actual number of data grants per NominalGrant Interval. For UGS/AD, the value of this parameter indicates the maximum number of Active Grants per Nominal Grant Interval. This is intended to enable the addition of sessions to an existing UGS Flow via the Dynamic Service Change mechanism, without negatively impacting existing sessions.

[and-mask ] [or-mask ]

IP Type of Service overwrite. Enables CMTS to overwrite original Type of Service (ToS) byte with new value.

[req-policy ]

Specifies which IUC opportunities the CM uses for upstream transmission requests and packet transmissions for this Service Flow, whether requests for this Service Flow may be piggybacked with data and whether data packets transmitted on this Service Flow can be concatenated, fragmented, or have payload headers suppressed.

NomGrantInterval

TolGrantJitter

Downstream Flow Only Parameters MaxLatency

Peak Rate

Issue 2.0

[max-lat ]

Maximum downstream latency — a service commitment by CMTS to forward a packet received on a network side interface to the RF interface within the specified number of microseconds.

peak-tr-rate

This is the peak rate in bps that can be achieved beyond TMAX after the burst (max-tr-burst) has been used. For example, if TMAX = 2 Mbps and Max-tr-burst = 8 MB = 64 Mbits, then you could set the Peak Rate to 6 Mbps. Since we have 64 Mbits available in the burst, we will transmit at Peak at 6 Mbps for 16 seconds, then fall back to 2 Mbps.

42 Additional Classifier Support

Additional Classifier Support

Overview The Additional Classifier Support feature allows customers to establish network connectivity between legacy voice equipment that uses Time Division Multiplexing (TDM), for example, a customer-premise PBX and a VoIP network north of the CMTS. The TDM-based equipment is connected to a gateway controller that uses PRI1 interfaces. This type of equipment requires more DOCSIS upstream flows (SIDs) than are typically supported by a cable modem. Enabling this feature permits additional classifiers per upstream flow from the modem. Used in conjunction with Multiple Grants Per Interval (MGPI), it permits the cable modem to support a number of phone calls that is greater than the number of UGS upstream flows that it (the modem) supports. In such an application the gateway controller communicates with the VoIP network elements. These might include a SIP Application Server and a Session Border Controller (SBC). The maximum active call capacity is dependent on all of the network elements including the call server, customer premise PBX, and other services that may be passing through the cable modem. Conventional VoIP traffic allows one call to be carried over a single dynamic upstream flow on a modem with a constant (fixed) Tmin/Tmax. When using this feature, multiple calls can be placed on a single flow. This is achieved using MGPI. The dynamic Tmin and Tmax of the flow vary up and down in discrete increments when observed over time as telephone calls carried by the flows come and go. The actual traffic per unit of time varies in the same way as seen in the output of the “show cable modem detail” command. The number of calls on a single flow is determined by the application server. This feature requires that the gateway device behind a CM be made known to the C4 CMTS by the modem configuration file. The 43.8 TLV of the config file must be set to a value of 0x00015C and the 43.200 TLV must have a value of 1. The maximum active call capacity is dependent on the call server, and other services may be passing through the cable modem. The two PRIs behind the cable modem and gateway support up to 46 active calls. The

The C4 CMTS supports only the flow aggregated version of Multiple Grants Per Interval (MGPI).

•

The CMTS does not support CALEA for CMs that are suppressing upstream classifiers. CALEA must be supported by other network elements.

•

Legal Intercept is supported.

The MGPI feature affects the output for the show interface allocated-bandwidth command. The columns showing the number of active calls actually show the number of active call flows. So, if two calls are sharing the same UGS flow using MGPI, the column will show one flow but not two calls. In order for this feature to work properly, Upstream Packet Classification Enforcement (UPCE) must be disabled on the C4/C4c CMTS. UPCE is disabled by default. If necessary, use the following command to disable UPCE: configure no operation mode upce

CLI Output for Diagnostics

This chapter provides an overview of the card diagnostic procedures for the CMTS. The card diagnostics can be used to determine if there is a problem with one of the cards in the CMTS chassis. You can use card diagnostics to isolate a problem to a particular card and even to a particular element on that card. The card diagnostic failure information can be used by the ARRIS support team to identify the root cause of the failure.

Running Diagnostics The CLI provides a command to initiate card diagnostics for the following modules:

CAUTION

Diagnostics are initiated only after the module is taken out of service. Therefore, diagnostics may be service affecting if the system is not in a duplex or CAM sparing configuration.

All diagnostic commands and results are logged to the system log automatically at the informational level and are also sent to the same terminal display associated with the CLI session. See chapter 44, Logging and the CMTS, for complete logging information and procedures. The following rules apply to running diagnostics on the CMTS: •

Module level diagnostics should be performed whenever a module fails to boot up, crashes, generates a serious error message, or is suspected of being faulty, or when it is requested by support personnel.

•

Diagnostics can be run only manually and only on modules that are taken out of service and shut down, but powered up.

•

An RCM must be active in order to run diagnostics on the CAMs.

Use the following procedure to verify new, replaced, or repaired modules or to test suspected faulty modules. The simplest diagnostic mode is to run all of the diagnostics for a given slot. First shutdown that module: configure slot shutdown Then run all diagnostics for that slot: configure diag Consult with ARRIS support representative for more information regarding diagnostics.

Generating Events and Traps

Routing Events to Local Volatile Logs

18

In order to provide maintenance personnel with real-time and historical operational state data, the CMTS must proactively monitor and route event messages. Operators can use several CLI commands to access event messages. This chapter first describes the logging mechanisms and then the commands used to generate, filter, and collect these important status messages.

Event Messages The CMTS generates asynchronous event messages, or events, in two ways: as part of normal operations and in response to error conditions. The CMTS uses asynchronous notification management (ANM) to log messages. Logging occurs when any unsolicited event is generated.

C4/C4c CMTS Rel. 8.0.7

Network management personnel can define and route event messages to several management subsystems. These subsystems include: •

A syslog server (up to eight syslog servers are supported)

•

One or more SNMP management stations

•

The local log: volatile and non-volatile (also found in the docsDevEventTable MIB table)

•

The CMTS console

•

Up to 16 telnet or SSH sessions

•

The logging history buffer

Other logging functionality can be managed through the DOCS-CABLEDEVICE-MIB.1 Each of these management subsystems is described later in this chapter.

How Event Messages Are Routed Event messages are routed according to their priority values. They are logged and subsequently used during system maintenance or network troubleshooting activities. All events carrying a routable priority are also stored in the volatile logging history buffer. Priority-based Event Routing — Each event is assigned an event priority. The event priority indicates the type and impact of the event on the CMTS operations.

Event throttling is explained in more detail later in this chapter. For the local log, system console, and telnet sessions, the routing is based only on the priority associated with the event. A brief description and graphic of these management subsystems and routing sequence appears in the following section.

Event Management Subsystems Figure 44-1 shows how events are routed to one or more of the event management subsystems within the CMTS. Each event management subsystem is described in the following sections. SNMP Management Station

The Simple Network Management Protocol Management station is an application that uses SNMP protocol to manage a device. The SNMP Management station receives and processes traps (also known as events) originating from the CMTS. Traps are useful for reducing the length of time between when an event occurs and when it is noticed by a manager.1 Events are routed first according to their priority, then they are under throttle control before arriving at the SNMP Management Station.

1. This time is called the event reaction latency.

Monitor (Telnet)

Figure 44-1: Event Management Subsystems on the CMTS Syslog Server

Syslog is a standard protocol for centralized reporting of system events. Its roots are in the Unix environment, but most modern devices use the Syslog protocol to report important events, operating parameters and even debug messages. Events are routed first by priority, then throttle control before arriving at the Syslog server. The CMTS supports up to eight syslog servers.

Local Log (volatile)

The volatile local log stores messages only in the DOCSIS® cable device MIB (docsDevEvent) and is only accessible via SNMP.

Local Log (non-volatile)

The non-volatile local log stores messages in the DOCSIS® cable device MIB. It also stores CMTS specific logs and places them in persistent storage — the flash disk.

System Console

The system console is the RS232 port in the System Control Module. This is the serial interface to the command line interface (CLI). There is a limit of one system console session at any given time.

Monitor

The monitor is the current telnet session. Events are seen only by the telnet session (monitor) that requested them.

History

The logging history buffer is a circular buffer that stores the last number of events that are delivered to any destination. All events that have a priority enabled for at least one destination are stored in the logging history. The default number of events stored in the logging history is 2000.

Event Message Throttling Overview

Using a throttle control protects the data network from exceeding a known threshold during bursts of event messages. Any number of asynchronous events transmitted into an operator’s management network may require throttling, especially if management traffic is carried in-band with user traffic. The CMTS implements a single system-wide throttle that applies to both Syslog message and SNMP TRAP transmissions. The network throttle can be set to one of four types: •

Unconstrained = no throttling

•

Limit = message rates are maintained below a defined threshold

•

Stop = messages are inhibited after reaching a defined threshold

•

All = all event messages are inhibited

By default, the CMTS network throttle type is unconstrained. Throttling Set to Limit

When throttling is set to Limit, then CMTS limits the amount of traffic transmitted onto the management network within a given time interval. This message rate is limited by a provisionable threshold. Should the number of events exceed this threshold, all events are inhibited for:

Throttling Set to Stop (Closed-loop Feedback)

•

until the throttling type is reset, or …

•

the interval begins again.

For closed-loop feedback throttling, the CMTS works together with a network management subsystem to jointly police the amount of traffic transmitted on the network. The CMTS automatically inhibits event transmissions when the number of events becomes excessive. Unlike Limit Throttling, transmission remains inhibited until a management subsystem directs the CMTS to resume.1

to display throttle settings, change throttle thresholds and intervals, and to set the throttle types. The commands include: configure logging throttle threshold configure logging throttle interval configure logging throttle [limit | stop | all] Each is explained in more detail in the following sections. configure logging throttle threshold 20 Where 20 is the number of events above which you want to begin throttling messages. The range is 1 to 4294967294. configure logging throttle interval 60 Where 60 is the interval, in seconds, from 1 to 4294967294. This interval corresponds to the threshold that throttling begins — if there are more than 20 events in a minute (60 seconds). Example of Throttling

Use the following command sequence to throttle logging to 1 event per second: configure logging throttle threshold 1 configure logging throttle interval 1 configure logging throttle limit Display the logging configuration: show logging The CMTS displays the logging settings, including how many event messages have been throttled. Sample output: Throttle: type=limit, threshold=1, interval=1, notifications=1356, throttled=85 Wait five seconds to allow the CMTS to refresh and display the logging configuration again: show logging Sample output: Throttle: type=limit, threshold=1, interval=1, notifications=1405, throttled=113

This second output shows that the number of throttled event messages has risen to 113. Change Event Throttle Type

Use this command, if throttling conditions permit, to reset the throttling type to the default, or unconstrained configuration. configure logging throttle [limit|stop|all|interval|threshold] Where limit = message rate limiting at a given threshold stop = closed-loop feedback throttling all = complete throttling of all CMTS events interval = time during which the trap threshold applies threshold = number of trap and syslog events to be transmitted per interval before throttling. configure no logging throttle

Configuring Event Routing Event messages may be routed to the Syslog host, SNMP servers, local volatile log, local non-volatile log, console, or monitor. Each location has specific restrictions and parameters which are explained in the sections that follow. Syslog Server Description

A Syslog server may be used to collect messages from the CMTS. To configure priority-based routing of CMTS events to a Syslog server, the Syslog host IP address must first be configured. You are not required to configure Syslog event priorities and the Syslog facility, but you should be if you desire values other than the defaults. The CMTS does not route events to a Syslog server unless the server’s IP address is configured. If the Syslog server is configured, but you wish to stop sending any events to it, enter the following CLI command: configure no logging syslog

Restrictions and Defaults for Syslog Server

You may configure from one to eight Syslog servers. By default, the CMTS routes any event with priority critical (3), error (4), warning (5), or notice (6) to the Syslog server(s). However, to send other priority levels to Syslog or SNMP, they must first be enabled for the local volatile log or local non-volatile log. Also by default, the CMTS sends all Syslog messages to the Syslog facility local0. The facility may be changed to local0, local1, local2, local3, local4, local5, local6, or local7.

Multiple Syslog Servers

CLI Commands for Multiple Syslog Servers

The CMTS has the ability to send logging messages to multiple (from one to eight) syslog servers. Multiple syslog servers share the following characteristics: •

All syslog servers share the same priority table: if one server is configured to receive priority notifications, they will all receive the notifications

•

Throttling is shared by all syslog servers: if throttling is set to inhibit notifications, then none of the servers will receive them

•

The syslog notification counter is pegged (incremented) each time a notification is sent to any syslog server

•

The dropped counter is pegged (incremented) each time a notification fails to be sent to any configured syslog server.

In order to add or remove a syslog server, use the following command: config [no] logging host [facility ] The facility defaults to local0. To change the facility for all currently configured syslog servers, enter the following command: configure logging facility To display syslog configuration and utilization statistics: show logging syslog The sample output below reflects a CMTS configured for four syslog servers: C4# show logging syslog Syslog:

hosts (ip address 10.10.0.10 10.10.0.13 10.10.0.12 10.10.0.11

facility): local0 local3 local2 local1

notifications=1319, throttled=0, dropped=3

Configure Syslog Server to Existing Network

This command configures the Syslog server to 10.16.1.2 (this host IP address is meant as an example): configure logging host 10.16.1.2

Configure Local Facility First

C4/C4c CMTS Rel. 8.0.7

This command sends all Syslog messages to the Syslog facility. In this example it is called local4. configure logging facility local4

Send All Informational Messages to Syslog

The following command sends all informational messages (priority 7) to facility local4 of the Syslog server. The command will fail if priority 7 is not first enabled for the local volatile or local non-volatile logs. configure logging syslog 7

Disable Informational Messages to Syslog

This command disables all informational messages previously routed to the Syslog server. configure no logging syslog 7

Override Priority Settings

This command overrides the priority setting and allows a specified event ID to do one of three things: •

admit, or

•

control by priority, or

•

inhibit.

configure logging override event The outcome is dependent upon the current priority settings. Use the show log history detail command to find the ID number of a given event. Overriding an event is a way to keep the log buffer from overflowing; typically it is used to prevent the system from logging a particular low-priority event or problem that cannot be corrected right away.

Event Routing Example 1

Use the following series of commands as an example to route emergency (1) and alerts (2) messages to the Syslog server, and to verify that the change was implemented: configure logging syslog 1 configure logging syslog 2 show logging syslog End of example

Routing Events to Local Volatile Logs This section contains commands used to route events to the local logs. Local Log Restrictions and Defaults

By default, the CMTS routes any event with priority emergency (1), alert (2), critical (3), and error (4) to the local logs . In addition, the local volatile logs also receive events with the warning (5) and notice (6) priorities. Before clearing the priorities for local volatile servers, the priorities must first be cleared for Syslog and SNMP.

Configure Local Logging Levels

Overview The term fully qualified domain name refers to a complete name for a host or computer connected to the Internet. The name is said to be complete because it contains the host name, domain name or names, and root. A Domain Name System (DNS) server uses it to resolve the FQDN to the correct IP address. This feature is intended for MSOs that use IGMP statically provisioned IPv4 multicast groups or the advanced mode DOCSIS Set-top Gateway (DSG). The advanced mode requires that a DSG source IP address and a multicast group address be manually configured on each C4 or C4c CMTS. Whenever these addresses change they must again be manually configured on each CMTS. This feature enables the MSO to replace the DSG tunnel addresses or statically provisioned source addresses for multicast groups with FQDNs. If a change is required, the MSO can simply update the new source address and group address information of the FQDN in the DNS server instead of manually in all of the CMTSs.

C4/C4c CMTS Rel. 8.0.7

In addition, the CMTS allows the use of a hostname in the configuration of the classifiers and static IGMP joins. If only the hostname is specified, the CMTS utilizes its configured IP domain name to complete the FQDN for the DNS lookup. With this feature enabled, the CMTSs in the network check the DNS server periodically using the provisioned FQDNs. If new information is available, the CMTS automatically removes the prior multicast configuration and joins the multicast group using the new source address. The end result is an automatic propagation of the new multicast configuration without manual intervention except for entering the appropriate DNS record on the DNS server. The C4 CMTS maintains the DNS server list and the default domain name list for all applications. The CMTS bases the frequency of the DNS query messages on both the current Time-To-Live (TTL) value of the FQDN to IP binding and on the poll interval setting. When the TTL expires, a query is sent by the CMTS to the DNS server to again resolve the FQDN. Limited Support for FQDN Feature

Support for this feature is limited to the following applications: •

DOCSIS Set-top Gateway (DSG) tunnel classifiers for pre-DOCSIS 3.0 Set-top boxes (STBs) on MDF-disabled MAC domains

•

Statically joined IGMPv3 (non-DSG) pre-DOCSIS 3.0 cable modems on MDF-disabled MAC domains.

•

This feature supports the association of an FQDN with only an IPv4 source address. Association with an IPv6 address is not supported.

•

An FQDN cannot be used for the multicast destination or group.

•

The frequency of CMTS DNS queries is based on the Time-To-Live (TTL) value of the FQDN-to-IP binding.

•

This feature does not support IGMP static host joins. It supports only IGMP static router joins.

•

When the FQDN-to-IP binding changes, the C4 CMTS reestablishes only the affected DSG or IGMP statically provisioned multicast groups. Forwarding packet counts in this case are cleared. These counts are not carried forward because they are specific to the source/group addresses.

•

Other than the enhancements specified in this document, the operation of statically-joined IGMP will be consistent with that in Release 7.4.

•

The C4 CMTS supports a maximum of 25 FQDN cache entries.

•

When the FQDN-to-IP binding changes, the Downstream Channel Descriptor (DCD) messages will be modified if they include DSG tunnel classifiers. The classifiers will be modified to reflect the new IP address.

•

If the C4 CMTS polling reveals that the FQDN-to-IP binding has changed, then any DSG or IGMP data forwarding based on that binding must be stopped. This happens when the polling response does not indicate a binding or when it indicates that the FQDN is bound to something other than an IPv4 unicast address.

•

When an FQDN to IP address binding is removed, dependent DCD messages will be modified according to the following conditions:

-

•

If affected DSG tunnel classifier(s) are currently included in the DCD, the classifier(s) will be removed from the DCD. - If affected DSG tunnel classifier(s) are the sole classifier(s) for tunnel(s) that are currently included in the DCD, the tunnel(s) will be removed from the DCD. When an FQDN to IP address binding is regained, dependent DCD messages will be modified according to the following conditions:

-

•

•

If affected DSG tunnel classifier(s) were removed from the DCD, the classifier(s) will be reestablished in the DCD to reflect the IP address. - If affected DSG tunnel classifier(s) were the sole classifier(s) for tunnel(s) previously removed from the DCD, the tunnel(s) will be reestablished in the DCD. If for whatever reason the DNS server does not respond to queries from the CMTS, then at some point the FQDNs go into a timeout state. The C4/C4c maintains FQDNs in this state and assumes that the IP addresses of these FQDNs are still valid until the DNS server comes back online and changes them. The CMTS permits FQDN and PQDN names to be up to 154 characters in length.

-

•

The default domain name may be up to 96 characters in length. Domain names consist of one or more parts called labels. Each such label cannot exceed 63 characters in length. The C4 CMTS enforces RFC 3696 and RFC 1035 rules for domain naming. These rules are also called the LDH (Letter-Digit-Hyphen) rules.

-

Issue 2.0

“The LDH rule, as updated, provides that the labels (words or strings separated by periods) that make up a domain name must consist of only the ASCII alphabetic and numeric characters, plus the hyphen.

Under certain circumstances attempts to configure an FQDN will fail or generate a log message. The following are some typical examples: •

If a DSG tunnel classifier with explicit source and group addresses has been configured, it must be deprovisioned before the same classifier can be used for an FQDN. If you do not first deprovision the DSG tunnel classifier, the CLI command to assign an FQDN will fail.

•

If on the contrary a DSG tunnel classifier has been configured with an FQDN, then this DSG tunnel classifier cannot be reconfigured with explicit source and group addresses. The DSG tunnel classifier must first be deprovisioned before it can be reconfigured with explicit source and group addresses.

•

If the FQDN feature has configured an IGMP statically provisioned multicast group that has been resolved to an IP address, any attempt by the user to create an IGMP statically provisioned multicast group with the same source and group addresses will fail.

•

If the FQDN feature has configured an IGMP statically provisioned multicast group that has not yet been resolved to an IP address, and the user creates an IGMP statically provisioned multicast group with explicit addresses, and after that the FQDN resolves to the same source address, then this FQDN will be saved. The CMTS will generate a log message to notify the user that this configuration may not be what he or she intended. The saved FQDN will take effect only if the IGMP statically provisioned multicast group with explicit IP addresses is deprovisioned.

Dynamic Services (DSx) / Dynamic Quality of Service (DQoS) provides for guaranteed Quality of Service for voice applications using DOCSIS 1.1 Dynamic Services (DSx) functionality. This mode accepts DSx signaling from any DSx-capable modem. DSx DQoS VoIP does not provide full PacketCable™ operation within the CMTS. DSx DQoS Provisioning on the CMTS

The following command should be run for all cable-macs which will be used for DSx DQoS call processing: configure interface cable-mac authorizationmodule open-dynamic-flow-policy This command allows for authorization of non-PacketCable DQoS through DSx signaling on the CAM. Open-dynamic-flow-policy must be enabled (the default is enabled). Enabling open-dynamic-flow-policy is required when running with non-ARRIS MTAs. If only ARRIS Touchstone™ Telephony Modems or Touchstone™ Telephony Ports are used, this setting can be disabled to provide a higher level of protection against theft of service. The following CLI command can be used to alter timers on the CMTS: configure cable max-qos-admitted-timeout Default =

C4/C4c CMTS Rel. 8.0.7

NOTE If DSx DQoS VoIP is enabled, the admitted timeout should be set at 200 seconds (the default), and the active timeout should be set to 30 seconds. This command is for DSx DQoS; it has no effect on PacketCable. The defaults ensure that inactive resources are released. Increasing these default values or setting them to 0 (which represents infinity) is not recommended. The default values serve as a precaution for freeing resources in the event that any device or transmission path in the network does not perform as required.

This chapter is meant for customers using Business Services over DOCSIS for Layer 2 Virtual Private Networks. (BSoD L2VPN).

Background Information The following paragraph from the DOCSIS BSoD specification is a description of the background and business application of this feature:

Data networking between the multiple sites of commercial businesses represents a significant business opportunity for cable operators. Commercial data networks are usually implemented with private pointto-point data connections such as Frame Relay, ISDN, or ATM virtual circuits, often with equipment that provides transparent delivery of layer 2 Ethernet LAN packets. A service that interconnects subscriber enterprise LANs with Layer 2 forwarding is called Transparent LAN Service (TLS). (Data-Over-Cable Service Interface Specifications Business Services over DOCSIS®, Layer 2 Virtual Private Networks, CM-SP-L2VPN-I08-080522, May 22, 2008.)

C4/C4c CMTS Rel. 8.0.7

This same specification goes on to explain that a TLS can be created using BSoD. From the point of view of the business enterprise using BSoD, the TLS may include CPE from more than one CMTS in the cable operator’s network, other LANs attached to CMs, and any other LANs bridged to the customer’s VLAN in the IEEE 802.1Q-compliant bridge in the cable operator’s backbone. The CPE in the TLS can be managed or operated just as if they were on a private Ethernet LAN, with IP addresses assigned by the TLS enterprise and taken from its subnet. The IP subnet of the TLS does not need to be coordinated with the enterprise clients or customers on the cable side of the TLS. Finally, the LAN subscribers in the TLS are isolated from the other customers in the cable operator’s HFC network(s) and from other L2VPNs.

Overview The BSoD L2VPN feature provides point-to-point transparent Layer-2 forwarding between a CM and a network-side Layer-2 device using one or two provider-imposed Q-tags to multiplex the packets belonging to each L2VPN instance on the designated L2VPN network interface between the C4 CMTS and the network-side device. These provider Q-tags are imposed or deposed by the CMTS and are not transmitted to or received from CPE devices on the cable interfaces. Any customer Q-tags imposed by CPE devices are considered to be part of the L2VPN payload and are not considered to be service delimiting to the CMTS. BSoD does not require the CMTS to learn MAC addresses. MAC address learning is not required in the downstream direction because of the one-to-one mapping between the Q-tags and the downstream CM. It is not required in the upstream direction because all traffic for all L2VPN instances arrives on known L2VPN upstream service flows (SFs) and is vectored to a single active egress L2VPN network interface. Since CPE-imposed Q-tags are not trusted as L2VPN membership tokens, all L2VPN traffic from CPE must arrive on one or more upstream SFs designated during CM registration as belonging to the L2VPN instance. This is done with an L2VPN TLV encoding in the CM configuration file that provides the upstream Q-tags and Priority values to be used when transmitting these packets on the active L2VPN egress network interface. An L2VPN instance may be configured with either one or two 12-bit Q-tags. Single Q-tag encapsulated L2VPN instances provide a numbering space of up to 4,000 values; dual Q-tag encapsulated L2VPN instances provide up to 16 million values.1 However, the CMTS supports a maximum of 16,000 L2VPN instances identified by either single or dual Q-tags that may be taken from anywhere 1. Dual Q-tags are also known as Q-in-Q or QinQ.

within the Q-tag number space. An outer Q-tag may have a Q-tag only in the range of 2-4094 because Q-tags 0, 1, and 4095 are reserved by IEEE 802.1Q while inner Q-tags may be numbered from 1-4095. Within a given CM one or more SFs may share the same Q-tags, so the CM configuration file may contain either a single L2VPN TLV encoding that applies to all SFs or it may contain individual L2VPN TLV encodings that apply only to a single SF. Either way, individual SFs are configured for L2VPN treatment in the CMTS during CM registration. The CMTS does not support L2VPNs that are defined in dynamic SFs. When a downstream Q-tagged packet arrives on the active L2VPN ingress network interface in the RCM, the Q-tags uniquely identify the CM belonging to the L2VPN instance and hence the downstream cable port. Only individual values of the Q-tags identify L2VPN instances because there is no service type encoding in the Q-tags. This means that the Q-tag number space for single (or outer) Q-tags on a given physical network interface is shared between the existing L3VPN VRF Q-tag subinterface feature and this L2VPN Q-tag feature. Since the L3VPN VRF Q-tag feature only uses a single Q-tag, only the outer Q-tag of a Q-tag pair must be inspected to determine if the packet is to receive L2VPN or L3VPN forwarding treatment. Also note that the L2VPN Q-tags are assigned by L2VPN TLV encodings embedded in CM configuration files while L3VPN Q-tags are assigned in subinterface encapsulation commands by the CLI. Use the following command to designate the range of Q-tags that are reserved to L2VPNs. This will prevent Q-tag collisions between the L2VPN and the L3VPN features. configure l2vpn [no] vlanid-range [- ]

{single-qtag | dual-qtag}

When a downstream L2VPN packet arrives at the CAM, the packet is transmitted only on the downstream channel used by the CM. It is encrypted using BPI+ to ensure that it is received only by the target CM hosting the L2VPN instance. This BPI+ encryption is applied to individually-addressed (unicast MAC) and as well as to group-addressed (multicast/broadcast MAC) packets that belong to the L2VPN instance. This ensures that L2VPN group-addressed packets transmitted on the downstream channel are rejected by other CMs that do not have the correct BPI+ SAID to decrypt the L2VPN packet. Furthermore, when the target CM is L2VPN-compliant under the BSoD L2VPN specification, then this CM forwards the L2VPN packet only to the Cable Modem Customer Interface (CMCI) preventing its own eCM IP host stack or other embedded eSAFE devices from receiving the packet. On the other hand a non-compliant CM forwards all unencrypted downstream IP and ARP broadcast packets to the CMCI as well as to all internal eSAFE devices and the eCM IP host stack. Not all cable modems are L2VPN capable. An L2VPN-compliant CM reports its L2VPN capabilities during registration. The preferred mode of operation is to provide subscribers with L2VPN-compliant CMs when carrying native

C4/C4c CMTS Rel. 8.0.7

IP/ARP traffic in the L2VPN tunnels. This ensures the maximum privacy for the L2VPN subscriber and the maximum performance for the CM and CMTS. The CMTS only supports non-compliant CMs when explicitly enabled by CLI command. CMs that signal L2VPN capabilities are always permitted to register with correct L2VPN TLV encodings, but noncompliant CMs are allowed to register with L2VPN TLV encodings only when this policy is explicitly allowed. L2VPN-compliant CMs must register with L2VPN capabilities that include Downstream Unencrypted Traffic (DUT) filtering mode and eSAFE host identification. In particular, the CMTS does not perform DHCP snooping for eSAFE host MAC addresses, nor does it support Downstream IP Multicast Encryption (DIME) for non-compliant CMs. Thus, these CMs form L2VPN tunnels that are called leaky because the packets can be forwarded to endpoints outside the VPN tunnel. It is the cable operator’s responsibility (via explicit CLI commands) to allow these non-compliant CMs to register with L2VPN TLV encodings.

Additional Information Customers using the ARRIS implementation of BSoD L2VPN should be aware of the following:

47-4

•

The ARRIS CMTS provides the point-to-point L2VPN service model but not the point-to-multipoint model described in the DOCSIS spec.

•

Each modem using BSoD must have a unique config file with its own unique Q-tag or Q-tag pair.

•

Modems using BSoD must have BPI+ enabled.

•

The chassis must be equipped with the following modules: RCM, 16D CAMs or XD CAMs, and 12U or 24U CAMs.

•

Single and Dual Q-tags are supported, other types of Network System Interface (NSI) encapsulation are not supported.

•

The CMTS supports a maximum of 16,000 dual-tag L2VPNs.

•

The CMTS supports a maximum of 4,093 single-tag L2VPNs.

•

FlexPath bonded modems do not support this feature.

•

The use of L2VPN non-compliant modems is permitted in this implementation per the DOCSIS BSoD spec, but results in leaky L2VPN tunnels which fail to exclude unencrypted ARP and IP broadcasts. If you wish to configure BSoD using non-compliant modems, and if these non-compliant modems are PPPoE clients, then the leakage is benign because such clients ignore non-PPPoE traffic.

•

BSoD tunnels are not considered to be a part of general ISP traffic; therefore, they are not included in Legal Intercept captures.
