How to configure SFM/ Card/MDA in Nokia SR 7750/77XX series routers

We going to discuss how to configure and bring up the Nokia chassis for the first-time installation like SFM, IOM/IMM Card, and MDA on Nokia 7750/77XX series router.

SFM Card - Switch Fabric Module which is an internal backplane used to switch traffic between different slots on the router chassis.

IMM -  Integrated Media Module which is your line card with a fixed number of media/ports

IOM - Input/Output Module this type of card we can insert different types of media/ports based on the supported type by each Chassis.

Let us explore how to identify and configure our Nokia SR series routers.

1. First find the SFM Type inserted on the Nokia Router.


as per the output we need to configure SFM5 to bring up the Switch fabric module


A:SR1# configure sfm 1 sfm-type m-sfm5-12

Now SFM is configured let's find the Card Type using the "show card" command 

*A:SR1# configure card 1 card-type "iom3-xp"


Now, we are in the final phase to bring up the ports. check and configure the MDA inserted on the line card.

*A:SR1# configure card 1 mda 1 mda-type "m60-10/100eth-tx"



Now the ports are up and we are ready to configure the ports to serve the purpose.

Epipe Configuration on Nokia 7750 SR This article explains how to configure epipe between Nokia SR routers. The Cisco term is referred to as xconnect and the juniper term is L2circuit. Basic Theories: Epipe name itself identifies it's a point-to-point connection that uses Ethernet encapsulation to pass data bits/bytes between two endpoints. Service provider core act as a layer 2 switch for customer traffic. In other words, this helps to extend the IP segment of the same subnet shared between 2 different locations. Topology: ISIS Level 2 and LDP are preconfigured. let's explore the setup to configure epipe and initiate traffic between the 2 sites. LDP is used to signal the Service label between end nodes participating in epipe. Nokia: SAP-MTU and Service MTU play an important role. To bring up the epipe between 2 end nodes we need to take care of Service-MTU and Sap port MTU. SAP-port MTU and Service MTU should be the same if the encapsulation is null. If the encapsulation is do
