Let’s get started, we shall first have an overview about the mini OLT turn up procedure.

 

Before starting with the turn-up procedure, let us understand the internal and external communication management in ISAM. For internal communication between the controller and the IACM (The management instance of the NT and the LTs) and IHUB (The management management instance of the Router on the NT), ISAM defines a default internal communication VLAN with the VLAN ID 4094. This VLAN ID 4094 is fixed in the software and cannot be used externally. The external VLANs can be configured and these are used for all layer 2 communications outside of ISAM. The range available for external VLANs is 1 to 4093.  

 

 

One of them is used as the management VLAN ofmanagement the ISAM to reach the controller The management IP interface gives the ISAM the IP address and is freely configurable

 

The turn-up procedure for 7362 DF-16GW Mini OLT requires configuring ISAM to be reachable for management. For layer 1, configur configure e the network network port (or ports ports)) on the NT and configu configure re LAG if required. For layer 2, configure the external management VLAN. For layer 3, configure the management IP address and default gateway. For layer 4, configure the SNMP settings for IACM in order to manage the ISAM from EMS systems like the 5520 AMS. In some cases SNMP V3 and SFTP are required and should be provisioned accordingly. Next are the additional system settings like system ID.

 

This slide provides an overview of the Physical ports on 7362DF-16GW Stand-alone Stand-alone Mini OLT This node acts as a stand-alone mini OLT. The controller card provides eight SFP+ uplink ports. The LT card is fixed and has 8 XFP ports for 4 NGPON2 ports or 16 GPON ports, depending on the XFP type that is used. It can be deployed in the Central Office or in a remote location. Several input power variants exist. Please note that the GE port is not usable in CLI or AMS.

 

In order to perform a turn up procedure you have to connect to the CRAFT port of the network element. Depending on the type of NE the cable needed to connect to the CRAFT port is different. 7362DF-16GW is the one only one which needs a standard USB cable 2.0 A male to micro-B cable. In the PDF file “736x_CRAFT_over_USB” “736x_CRAFT_over_USB” which comes with the course material you can find additional information regarding the various USB cable types needed, direction to do download and install the drivers needed. The craft port for the 7362 is shown shown on the slide.

 

Once connected to the CRAFT port hit the nt r key once to trigger the port. Type C to get into the CLI. Login into the CLI as shown. When you log in the first time via CLI, log in as “isadmin” with the password as shown in the slide. The system will prompt you to change the password and then you may change it, preferably to “ANS#150”. The new passwor password d shown here is the most common common one used. used. Howe However, ver, it does not mean that this is must. The “isadmin” user password can be freely chosen but the one shown here is typically set up in all ISAMs. This first-time login password is i s also the password after a reset to default database or to factory settings.

 

The NT card (control slot) of the 7362 DF-16GW Mini OLT has ___ SFP port(s). 1. 2. 3.

Chapter 2 - Layer 1 – Physical port port configuration. Here in this chapter you you will understand about the Layer 1 Physical port configuration.

 

Network port Network portss on the NT have to be admini administra strativel tivelyy turned turned on and few addi additional tional parameters might be set. The port configuration on NT is performed through the "configure ethernet line" command. Bring up the admin state of the port with the command “configure ethernet line port admin-up”. Depending on the configuration at the other end of the NT port, auto-negotiation can make the NT port’s operational status down. The “autonegotiate” parameter enables speed and duplex auto negotiation on such Fast Ethernet ports. When auto-negotiation is enabled on a port, the link attempts to automatically negotiate the link speed and duplex parameters, ignoring the configured duplex and speed parameters. To avoid depending on the other end, disable or enable auto-negotiate at the port. To disable auto-negotiate, use the command “configure ethernet line nt:xfp:1 mau 1 no no autonegotiate ” and to enable it, use the command “configure ethernet line nt:xfp:1 mau 1 autonegotiate ”. To check the media attachment unit, use the command “show ethernet mau”. If you see, for example, that an electrical SFP is inserted of type 1000 1 000 base tfd, configure

 

this type as the new mau type and power up the administrative status of the sfp. The “show interface port” displays the admin state and the operational state of the port. This should be “up” now.

13  

This example shows the “show ethernet mau” command, which displays the media attachment unit table. As per the example, the port nt:xfp:1 advertises 1G electrical capability and the media are available for operation, but the auto-negotiate is disabled. The show interface port command provides the administration and operational status of the port. In this example, the ethernet line at nt:xfp:1 is up for administration and operation.

 

Operators can also check if there is SFP mismatch through th rough the alarm current table. The “show alarm current table” displays the alarm in the NT port. To view the details on the “uplink etherent sfp” alarm, use the command “show alarm current uplink-ether sfp”, followed by the alarm index number. In addition to other details, operators can also see if there is an sfp mismatch in the output. In the example, we see that there th ere is an “uplink etherent sfp” current alarm.

 

The basic concept of the LAG is that multiple physical ports are combined into one logical bundle. This provides benefits including: •

•

Increased capacity - traffic may be balanced balanced across the member ports to provide increased aggregate throughput. Link redundancy - the LAG bundle can can survive the loss of one one or more member links.

The characteristics of a LAG are: In most implementations all the ports consist of the same physical type. (10/100/1000BASE-T), (10/100/1000BAS E-T), depending on the th e switch implementation different types of physical ports are supported. Speed and Duplex - Since traffic traffic is distributed distributed by a simple hash, it is not possible to combine links of different speeds in the same bundle. Ports can be added and removed on the group without the need to bring the group down, that means services are not interrupted, in terrupted, only the capacity of the group is increased or decreased. Data should be sent to group and not to the physical ports anymore. The group will take care of the distribution of the data d ata over the physical links. Link Aggregation Control Protocol (LACP) (LACP) is the control protocol used for Link Aggregation Groups. All ports in a LAG must share the same characteristics. LAG changes can be done only to the primary port configuration and these changes are automatically made to the non-primary ports.

 

The LACP provides a standardized means for exchanging information between Partner Systems on a link to allow their Link Aggregation Control instances to reach agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. Also the use of LACP requires some operator control. Especially important is the configuration of actor-keys per physical link. This parameter identifies the Link Aggregation Group and is exchanged within the protocol to the peer side to assure that the links of one link aggregate really connect to the same node. If a link fails, this is detected by LACP. It removes the link from the active set of the link aggregate. When the link comes up again, LACP puts the link back in the active set of the link aggregate If a network link in a load-sharing group is lost, the traffic is redistributed across the remaining links of the load-sharing group. The failure can be detected by means of detection of link loss on the physical link.

 

The link aggregation of the uplink ports in 7362 ISAM DF/SF increases the capacity of the resulting ISAM single network interface, and also provides link protection. In 7362 LAG is possible on the eight ethernet ports. Link Aggregation Groups are defined by configuring individual physical links with identical link aggregation parameters. Load balancing across links is supported. Depending on the type of traffic (L2, IP, MPLS) the load balancing is based on the combination of traffic parameters like SrcMAC, DstMAC,SrcIP, DstIP, Tunnel/Service Label, Physical Port and/or TCP/UDP Port numbers.

 

The LAG is configured in ISAM by first configuring the physical ports. As ports in a LAG share the same characteristics, auto negotiation is turned-off through the "no autonegotiate" parameter. The LACP parameters are set next, where the lacp system priority can c an be set. The LAG port parameters are set next. Especially important is the configuration of actor-keys per physical link. This parameter identifies the Link Aggregation Group and is exchanged within the protocol to the peer side to assure that the links of one link aggregate really connect to the same node. The next step is to configure the link aggregation group parameters. The max active port number in a LAG in Mini M ini OLT is 8. The configured ports are added with the LAG through the configure link-agg group (group (gro up name ) por portt (port (port id ) comma command. nd. You can check the status of the link-aggregation port, group and and member port details using the ‘’ show link-agg port-info ‘’ command It might be a good g ood idea to put even a single network port used u sed for management in a LAG from the beginning, since this prevents a service interrupt which will be caused by reconfiguring a single port configuration into a LAG configuration.

Chapter 3 – Layer 2- Management VLAN & Layer 3 Management IP. IP. This chapter sheds light on the Layer 2 and Layer 3 configuration.

 

Layer 1 is configured. Now we have to understand, how Layer 2 and Layer 3 are implemented implem ented on a Mini OLT. OLT. To create Layer 2, for our management VLAN, use “configure system mgnt-vlan-id” mgnt-vlan-id” command. The management VLAN, in the example VLAN 4080, is created through the command "configure system mgnt-vlan-id“, followed by the VLAN ID number. The creation of the management VLAN establishes a connection between the ISAM and the default gateway.

 

3, we need to assign assign an IP address and configure configure the default To set up a Layer 3, route. The host ip address is assigned via the "configure system management host-ipaddress manual" command for IPV4 and “configure system management management ipv6 “ for IPV6. After configuring the host IP address, the default gateway has to be configured, which will be used as the next hop for the traffic. The default route is configured via the command "configure system management default-route“ for IPV4 and “Configure system management ipv6 default-route” for IPV6. In these exam examples, ples, we we can see commands commands when when the managem management ent IP address/subnet mask of the ISAM is 192.168.1.81/22, the management VLAN ID of the ISAM is 4080 and the th e default gateway IP is 192.168.0.1 For IPV6, the host is configured as 2017::21 2017::21 with mask 64 and the default-route is configured as 2018::1 A host IP address can only be changed if the default gateway is removed.

Now lets move on to the next chapter - Layer 4 SNMP SNMP and SFTP

 

If the ISAM would be managed by the 5520 AMS, SNMP has to be setup. The SNMP community is configured through the “configure system security” command. The security functions provided by the SNMP protocols v1 and v2 follow the Communitybased Security Model, where the data protected by a password is referred to as the community name. The community community name defined for the ISAM is public. The “Community Name” is a case sensitive character string of up to 32 characters and should match the SNMP setting of the AMS. The “host-address” can be used to define from which IP addresses you accept SNMP command. The source IP in the IP header for incoming SNMP frames are checked if they match within the host-address range, if not they will be dropped. If set all to zeros (0.0.0.0/0) you accept from from everyone. Operators can also restrict the SNMP managers managers by specifying an IP address with a subnet mask m ask instead of 0.0.0.0/0.The context is used to assign the SNMP setting to the management instance in the ISAM.

 

If you want to use SNMP V3, the configuration is done as follows: First the SNMP V3 user is created with the authentication and privacy setting as required. Next the SNMP V3 groups is created with the security level settings. The group is linked to either a single context or to all. Last the SNMP V3 user is mapped into a SNMP V3 group. Remember that authentication method values and privacy values should match with the settings defined in the AMS.

 

In the example you see the creation of a user, a group and the mapping of the user into the group.

 

In case SNMPv3 is used, then first configure the sftp protocol via the "configure system security filetransfer protocol" command. The SFTP user name and password are configured through the sftp-user option. In this example, the sftp protocol is configured with the sftp-user "amssftp.“ Remember that authentication method values and privacy values should match with the settings defined in the AMS.

 

The command "configure "configure system security snmp community public host-address host-address 10.15.10.206/24 context nt" configures ________. 1. 2. 3.

Chapter 5 – Additional Settings. After Layer Layer 4 configurations there are few additional settings that can c an be carried out, this chapter will illustrate the same.

 

An ISAM system ID identifies i dentifies an NE, and this is unique for each NE. The name that the ISAM gets in the AMS, must be provisioned and should be exactly same as in the AMS, otherwise an alarm will be raised. To prevent it, set the parameter “system id”. This is configured through the “configure system ID” command. The NE System ID prevents any LABEL mismatch alarm in the AMS.

 

Chapter 6 – Example. This chapter chapter provides you with with an example scenario for for the turn up procedure and the corresponding CLI commands.

 

Here is an example example for the complete complete Turn-up Turn-up procedure procedure for a Mini OLT - 7362 7362DFDF16GW
