LAG Configuration on Nokia Routers


Link Aggregation (LAG) Configuration on Nokia Routers


In the previous article we focus on how to configure Link Aggregation on Cisco and Juniper devices. Here we will see how is this configuration done on Alcatel-Lucent devices. Alcatel-Lucent 7750 Service Router will be our device.

Link Aggregation on (Alcatel-Lucent) Nokia Router
The term for Link Aggregation is LAG (Link Aggragation Group) in Alcatel-Lucnet.In Alcatel-Lucent routers also maximum 8 ports can be bundled in a LAG, and up to 64 LAG can be on a chassis.


The ports in a LAG must have the same characteristis, speed, duplex etc.


You can also download all Nokia Labs, on Nokia Configuration Labs Page.


In this part, let’s start with the configuration of the ports. We have ports 1/1/1 and 1/1/2. We must ensure that these two ports have identical speed and duplex. Let’s starts with RouterA.


A : RouterA # configure port 1/1/1
A : RouterA >config>port# ethernet no autonegotiate
A : RouterA >config>port# ethernet speed 100
A : RouterA >config>port# ethernet duplex full
A : RouterA >config>port# exit
A : RouterA # configure port 1/1/2
A : RouterA >config>port# ethernet no autonegotiate
A : RouterA >config>port# ethernet speed 100
A : RouterA >config>port# ethernet duplex full


Above, the “no autonegotiation” command is used to ensure that autonegotiation is disabled and only a specific speed is advertised.


We must remove the port binding from the interface between RouterA and RouterB. To do this use the below command.

A : RouterA # configure router interface RouterAB no port



Next, we configure the LAG and associate the ports with this LAG.

Link Aggregation – Part 1 (Link Aggregation Control Protocol, LACP)
Link Aggregation – Part 2 (LACP Configuration on Cisco Devices)
Link Aggregation – Part 3 (LACP Configuration on Juniper Devices)
Link Aggregation – Part 4 (LAG Configuration on Alcatel-Lucent Devices)
