Chapter 1 Topology Management

Chapter 2 Topology Management Topology management enables you to construct and manage the topology structure of the network. You can keep track of the operation status of the entire network by browsing topological views of the network. In topology management, you can upload topological data of network devices through topology auto discovery or by manually adding topology nodes. You can also add, delete, modify, and query topological devices. According to different management requirements of users, topology management provides such functions as non-hierarchically zooming, setting background, and auto layout. In this way, you can manage networks and devices easily. Topology management can poll network devices and refresh their status regularly, thus making the network view display consistent with the actual network topology. In addition, topology management can monitor polling status and alarm status of network devices through color changes of the topological nodes. Figure 1–1 shows the main window for topology management.

Figure 1–1 Main topological view

1-1

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 1 Topology Management

2.1 Basic Concepts The topology is a map of the managed telecommunications network in the NMS. It displays managed devices and links on the user interface using graphs and trees. Through the topology, users can perform such operations as configuration, alarm and performance. The topological objects that can be managed include nodes, submaps and links.

2.1.1 Concept Description I. Submap In the NMS, a large network can be divided into several smaller networks by region or something else to facilitate network management. In the topology, these smaller networks are known as submaps.

II. Node A node refers to a managed device that is mapped into the topology. For a single-frame device, a node represents the device. For a multiple-frame device, a node usually represents a frame in the device. Therefore, in the topology, a node and a device do not mean exactly the same.

III. Link A link refers to a connection between devices that is mapped into the topology. In the topological view, the displaying of links follows these rules: z

If there is any connection relation between two objects in the same submap, a link is drawn between the icons of the two objects. Double click the link, and you can query the detailed attributes, including the link name, link type and link status.

z

If there is any connection relation between two objects in two submaps, a shortcut icon is drawn at the lower right corner of each icon.

z

If there is any connection relation between the lower submaps or nodes in two submaps, a link is drawn between the two objects (two submaps).

IV. View In the NMS, different views can be used to display the topology, depending on the angle of observing network or the service range concerned. As examples, a physical view divides network topology structure based on regions or any other rules; an IP view divides a network into several smaller networks based on the IP network segment. Accordingly, the topology structure is organized in this way:

1-2

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 1 Topology Management

Each view corresponds to a device explorer and is concerned about different service points. Each device explorer includes several submaps, which show the network composition in the view. Each submap includes several nodes, as shown in Figure 1–2.

Figure 1–2 View

V. Role Switches in a cluster can play different roles based on the locations and functions. A cluster is a manageable network that comprises of multiple interconnected switches. It is assigned with a single IP address. All switches in the cluster must support Huawei Group Management Protocol V2 (HGMP V2). With the cluster management, the user can manage a group of switches without assigning an IP address to each member switch. In the NMS, depending on different service angles, device nodes of the same type can be defined as different roles to implement different operation and configuration modes. For example, a Quidview device node, which is not defined in the physical view, may be defined as a command switch or member switch in the Virtual Local Area Network (VLAN) view. The switches in a cluster can play the following roles. z

Command switch

The switch is assigned with a public network IP address and provides the main management interfaces for the overall cluster. A management command is first sent to the command switch for processing. If it finds that the command is destined to a certain member switch, it will redirect the command to the member switch.

1-3

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System z

Chapter 1 Topology Management

Member switch

The switch is a member of a cluster, which is not assigned with a public network IP address in normal situations. It only receives the management commands redirected from the command switch. z

Candidate switch

The switch does not join any cluster, but has the cluster capability and can become a member of a cluster. z

Independent switch

The switch can be discovered in the process of gathering cluster topology information, but has no cluster capability and cannot become a cluster member.

VI. Filter Filter is a special topological node. It can contain members. Currently, the filter often represents a multi-frame device. The multiple nodes under the filter represent the frames of the device.

VII. Polling status and alarm status Polling status: The NMS queries the status and other configuration data of devices regularly, and displays the queried status information in the topological view. The possible polling statuses include: Normal, unknown, offline, insignificant, minor, major fault, critical, loopback, and test. Alarm status: The device reports trap information to the NMS. Then the trap information is displayed in the topological view. The possible alarm statuses include: Critical, major, minor, and warning.

2.1.2 Icon Description Corresponding to the concepts provided in the previous section, the topological view uses different icons to indicate submap, node, link, view objects and their statuses, and role. For a node, a submap, or a link, the color of its icon shows its polling status. The status at the upper left corner of the icon shows its alarm status, lock status (locked or unlocked), and its role. Figure 1–3 shows a node which is locked, offline and is experiencing a critical alarm.

2.3 Deploying Devices Reasonable device deployment in the NMS can make the communication network more visual and improve the operability of the NMS. Generally, deploying device should experience four phases: Preparations–>Creating a Submap–>Adding a Device to the NMS–>Creating a Link.

2.3.1 Preparations Deploying a device is to deploy communication devices in the network in the topological view. Before deploying a device in the topological view, you should plan the topological submaps reasonably. If there are too many devices in a very large network, it is very difficult to locate and manage a device in one topological view. You can classify the topological view into topological submaps by: z

Geographical region, that is, the region where the communication device is located.

z

Device type, that is, the type of the communication device.

z

IP network segment, that is, the IP address of the communication device.

z

Manager of the device.

Note: z

Up to 300 devices can be added to each submap. If there are too many devices in a submap, the interface of the NMS will be much crowded and the devices will be overlapped. This will make locating devices inconvenient.

z

Submaps should be arranged in 5 layers at most. If they are arranged in too many layers, it will cause much trouble to operate on the NMS.

2.3.2 Adding a Submap There is a very large and complex communication network. To ease the management and operation, you can divide it into several subnets based on the geographical region, type or IP network segment of devices. Each subnet is mapped to a submap in the topology. Adding a submap helps you to manage the communication network easily. Each subnet can correspond to a submap.

2.3.3 Adding a Device to the NMS After planning the communication network and creating a submap, you should add a device to the NMS. 1-20

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 1 Topology Management

Take the two steps below to add a device to the NMS:

I. Configuring NMS and device data Before adding a device to the NMS, configure SNMP parameters at the NMS side and NMS workstation parameters at the device side. Get Community/Set Community must be exactly the same at both sides. In order to improve the security of the system, do not use the default community names. You should configure the following data in the NMS: 1)

The network management protocol and parameters supported by the managed devices.

If the SNMP is used to manage the devices, you should configure the default SNMP parameters of the NMS. See “Set Default SNMP Parameters”. 2)

According to the different device types, the following data should be configured at the device side:

z

Network management protocol and parameters supported by the managed devices.

z

ACLs of the devices.

z

Trap center.

z

Other parameters.

For different devices, different parameters need be configured at the NMS and device sides in different ways. For details, refer to the user manuals of the respective network management subsystems.

II. Adding a device There are two methods to add a device to the NMS. z

Add devices manually

First specify the type, IP address, name, submap, network management protocol and parameters of the device you want to add. Then add the device to the NMS. z

Auto device discovery

First specify the IP network segment you want to search, automatically discover the desired device within the network segment. Then add it to the NMS. The auto discovery mode applies only to the devices that support the SNMP. See “Auto Device Discovery”. After adding a device to the NMS, you can copy/cut and paste the device to move it among different submaps to modify the layout of the topological view.

2.3.4 Add Links After adding a device to the NMS, you can add the physical links between devices in the NMS. If a logical connection exists between two submaps, between a submap and

1-21

a device, or between two devices, you can add the corresponding virtual link to the NMS.

Chapter 3 Fault Management

Chapter 3 Fault Management Fault management is used to process the device alarms and the alarms of NMS itself. The management functions include querying the alarm history and operation information of devices, and querying and configuring device alarm information. The main window for fault management is shown in Figure 3-1.

Figure 3-1 The main window for fault management

3.1 Basic Concepts 3.1.1 Alarm Definition Alarm (event) information may come from various device modules or service boards. Alarms can be classified into operation information, fault alarm and recovery alarm by alarm type. Fault alarms and recovery alarms correspond to each other one by one. Alarms (events) can be classified into four levels in the descending order of severity: critical, major, minor, and warning. After an alarm is generated, the system broadcasts it to the terminals according to the condition of the configured terminals, mainly to the NMS users and Command Line 3-1

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 3 Fault Management

Interface (CLI) users. Whether an alarm will be reported the terminals are specified in alarm control.

I. Alarm ID An alarm ID consists of four bytes, indicating a unique alarm. Each alarm ID corresponds to an alarm. Generally, alarm IDs are allocated according to alarm type and alarm module type.

II. Alarm level Alarm (event) level is used to identify the severity of an alarm. Alarms can be classified into four levels in the descending order of severity: critical, major, minor, and warning. z

A critical alarm refers to a global alarm that endangers the normal operation of the device and needs to be handled, like power failure, output clock failure, and so on.

z

A major alarm refers to a board or line failure within the limited range. The user services will be abnormal if the user does not handle it in time. Examples of such alarm include fiber cut, fault in physical line, and so on.

z

A minor alarm refers to an ordinary fault alarm or event alarm that shows the board or line abnormality, like the bit error on a physical line.

z

A warning refers to a status change or event that does not affect the system performance and user services but interests the operator. A warning may also be a message that prompts the recovery from a device abnormality.

III. Alarm category By function, alarms can be classified into power alarm, environment alarm, trunk alarm, hardware alarm, software alarm, operation alarm, communications alarm, service quality alarm, and error processing alarm.

3.1.2 Term Explanations I. Real-time alarm Real-time alarms refer to the alarms that are reported after the real-time alarm browser is started. The real-time alarm browser can automatically scroll down to display the latest alarms on the screen.

3-2

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 3 Fault Management

II. Current alarm Current

alarms

refer

to

the

unacknowledged&unrecovered

alarms,

unacknowledged&recovered alarms and acknowledged&unrecovered alarms. A current alarm requires human intervention.

III. Historical alarm Historical alarms refer to the acknowledged&recovered alarms. A historical alarm does not require human intervention.

IV. Real-time event Real-time events refer to the events that are reported after the real-time event browser is started. The real-time event browser can automatically scroll down to display the latest events on the screen.

V. Alarm acknowledgement By the alarm acknowledgement status, the user can easily identify which alarms have been handled and which alarms have not. Then the user can take different measures to handle the alarms in two different statuses. The system supports manual and automatic alarm acknowledgement.

VI. Alarm status transition In case of a device fault, the device sends an alarm to the NMS. The NMS receives the reported alarms in real time. For the time being, the NMS supports the alarms and events reported in form of MML and SNMP Trap. The latest alarms received by the NMS are unacknowledged&unrecovered. After the fault is eliminated, the alarm is acknowledged manually or automatically. When the NMS receives a recovery alarms, the alarm becomes recovered. The acknowledged&recovered alarm becomes a historical alarm and is not handled as a current alarm. Current alarms include all unacknowledged and/or unrecovered alarms, and they can be handled in a centralized manner. The alarm status transition model is shown in Figure 3-2.

For the time being, only the configuration of static IP-based PPP client is supported. If a PC serves as the PPP client, set "PPP" as the server type when setting connection attributes, and select the specified IP address when setting TCP/IP attributes. Other settings remain unchanged.

3)

The dial-up script should be compiled in consistency with the type of modem. It is hard to do so during the configuration of workstation dial-up service. Three types of modems are recommended: Robotics, Hayes, and Etek. Here we introduce the configuration of Hayes modem.

4)

Unix to Unix Copy Protocol (UUCP) software and PPP software should be pre-installed on the workstation (they are already installed on the current workstations). If necessary, use this command to install the PPP software:

#: pkginfo | grep ppp

II. Configuration procedure 1)

Check the connection of modem.

Connect the modem to the serial port, and then use this command to check whether the modem is properly connected (assume that the modem is connected to serial port A): 11-4

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

# tip /dev/cua/a connected

If “connected” is displayed, it indicates that the modem is connected to serial port A. In this case, if the modem can be configured by using AT commands, it indicates that the modem is connected properly. Otherwise, check whether the serial port cable and the modem are normal. Type “~” to quit the command “tip”. 2)

Configure the PPP.

Default settings of configuration script: z

The IP addresses of the PPP server and PPP client are set to “192.168.55.1” and “192.168.55.2” respectively.

z

The PPP server adopts ipdptpn network interfaces.

z

The login user name of the PPP client is “ppp_user”.

These parameters can be changed if necessary. Set the server: z

On the PC, load the file “ppp.tar” to the directory “/usr/local/rms/” as the user “root”. Note that this file is transmitted in binary system.

z

Log in to the workstation as a super user, and then decompress the file “ppp.tar”.

# cd /usr/local/rms # tar xvf ppp.tar z

Connect the modem to the workstation and telephone line, and then power on the modem. On the workstation, enter the PPP directory, and then configure the PPP server as below:

# cd PPP # sh setup_ppp.sh (or use “./setup_ppp.sh”). z

Specify the computer as the remote monitor server (options are client and server. By default it serves as the client): server

z

Input the serial port used (a or b. It is “a” by default): b

z

Rate of serial communication (19200bps, 9600bps, or 38400bps. It is 19200bps by default (We recommend that you press to accept the default value 19200bps).

Chapter 11 Remote Maintenance

Start “asppp”

# /etc/init.d/asppp start z

Stop “asppp”

# /etc/init.d/asppp stop z

After "asppp” is started on both the server and the client, ping the server to establish the dial-up connection.

# ping ppp_server [N]

Note: The dial-up may take a tong time. If you ping the server for the first time, a time-out might occur. "N" is used to set the time-out period of the command “ping”. You can check whether the connection is made by viewing the log files (see "Troubleshooting" later in this manual) or the status indicator in the mode.

III. Change default settings 1)

Change the default telephone number of the client

Modify the file “/etc/uucp/Systems” . The last row of the file is: UNIX Any PPP 19200 0,163 ...

11.4 Remote Maintenance Schemes The remote maintenance mode varies with the operating system platform and the remote maintenance tool software. This section details the remote maintenance modes of the iManager N2000 (Client/Server).

11.4.1 SUN workstation serves as the dial-up server This mode is used in situations where the server of the operator is a SUN workstation. It features high connection rate and high security. First set up the corresponding dial-up connection (see Section 10.1.3), and then follow these steps to perform the maintenance. 1)

Both parties establish communication connections in between. The remote maintenance client should get information such as the telephone number of the opposite end, dial-up user name and password. Then dial in the iManager N2000 NMS Workstation of the operator.

2)

The remote maintenance engineer runs the iManager N2000 Client, inputs “192.168.55.1: 9801” in the server input box, and then the user name and password provided by the operator, and clicks . After logging in successfully, the maintenance engineer can perform remote maintenance. 11-10

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 11 Remote Maintenance

Note: z

Both parties establish communication connections in between. The remote maintenance client should get information such as the telephone number of the opposite end, dial-up user name and password. Then dial in iManager N2000 NMS Workstation of the operator.

z

For the sake of security, set one TELNET connection for the SUN workstation and disable the FTP function.

11.4.2 PC/Windows2000 serves as the dial-up server This mode is used in situations where the server of the operator is a PC. It features high connection rate and high security. First set up the corresponding dial-up connection (see Section 10.1.2), and then follow these steps to perform the maintenance. 1)

Both parties establish communication connections in between. The remote maintenance client should get information such as the telephone number of the opposite end, dial-up user name and password. Then dial in the network management PC of the operator.

2)

The remote maintenance engineer runs the iManager N2000 Client, inputs “192.168.55.1: 9801” in the server input box, and then the user name and password provided by the operator, and click . After logging in successfully, the maintenance engineer can perform remote maintenance.

Note: z

If the dial-up connection at the server side is disconnected, restart the SS module of the NMS Server.

z

For the sake of security, the number of the login users is limited.

11.5 Troubleshooting I. Failed to connect to SUN workstation 1)

Check whether the connections are correct, especially the connection of the SUN workstation. Check whether the modem is connected properly. The telephone line should be connected to the jacket marked “line”.

2)

Make sure that connection of the modem is normal. If a message similar to

tip: /dev/cua/b: No such device or address all ports busy

11-11

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 11 Remote Maintenance

appears during the setup, it means that the modem is improperly connected. In this case, check the condition of the lines and make sure that the modem is switched on. Use

tip termb (or terma, respectively indicates that the modem is connected to serial port b or a) or tip -19200 /dev/cua/b (a) to connect the modem. If the message “connected” appears, it indicates that the modem is connected. In this case, you can input “AT”. If "OK” is returned, it indicates that the modem is normal. Input “~” to exit, and then set setup_ppp.sh again. If no “OK” is returned after you input “AT”, input “ATE1Q0”. If still no response is returned, replace the port or re-connect the modem. For more information about debugging modem, please see the document “Modem_conf.pl”. You can open this file with an HTML browser.

Note: To use terma or termb, the setup_ppp.sh must be set correspondingly. terma or termb is an entry to file “‘/etc/remote”.

3)

Make sure that the password of ppp_user input at the client side is identical to the one set at the server side. run “vi” to view the file “/etc/uucp/Systems”. The password of ppp_user is located at the last row (login: ppp_user word:) of the file. It must be identical to the one set at the server side. To change the password of ppp_user without setting PPP again, log in as a superuser, and use “/usr/bin/passwd ppp_user” to change the password of ppp_user.

4)

The file “/var/adm/log/asppp.log” (the same as etc/log/asppp.log) records the operations performed by the PPP user. You can view the dial-up connection progress in ”tail -f /var/adm/log/asppp.log”.

5)

If no change occurs in “tail -f /var/adm/log/asppp.log” when the client dials, it means that the PPP user has not logged in or the login shell is not “/usr/sbin/aspppls”. Modify the file “/etc/passwd” directly, or change the login shell of the PPP user to “/usr/sbin/aspppls“ in “admintool”.

6)

If the following message is displayed in “/var/adm/log/asppp.log”:

10:13:22 get_fifo_msg: can't find path with peer_system_name ppp_user

It means that the PPP user name set at he client side might be inconsistent with the one set in ”peer_system_name” in “/etc/asppp.cf” at the server side. Please make them consistent. 11-12

User Manual HUAWEI iManager N2000 Fixed Network Integrated Management System

Chapter 11 Remote Maintenance

II. No display in the SUN workstation login window The cause is possibly related to cables. Check whether the cables meet the hardware requirements.

III. Frequent problems with the PC workstation serving as the dial-up client 1)

Illegible characters appear in the PC client login window. The likely reason is that the rate of the PC client is not set to 19200.

2)

Make sure that the dial-up server is correctly installed and is bound with TCP/IP. Problems may occur if multiple dial-up servers are installed.

IV. How to check wether the PPP software has been installed UUCP software and PPP software should be pre-installed on the workstation (currently, they are already installed on the workstation). Run this command to check whether the PPP software has been installed: # pkginfo | grep ppp The system prompts that the PPP software has been installed.

V. The modem at the server side does not answer. Set the modem to auto answer mode. For Robotics, Hayes and Etek modems, run the scripts again and select a correct modem type (case-sensitive). For another modem type, set the corresponding AT commands by referring to the configuration manual.
