Syntax: [no] route-only
To disable Layer 2 switching only on a specic interface, go to the interface conguration level for that interface, and then disable the
feature. The following commands show how to disable Layer 2 switching on port 2.
device(config)#interface ethernet 2
device(config-if-e1000-2)#route-only

Conguring a Layer 3 Link Aggregration Group (LAG)
FastIron devices with Layer 3 images support Layer 3 LAGs, which are used for routing and not switching. For details on how to create a
LAG, refer to Link Aggregation in the FastIron Ethernet Switch Platform and Layer 2 Switching Conguration Guide. Perform the
following steps to enable routing on a LAG:
1. In the global conguration mode, run the interface ethernet command to enter the interface conguration mode of the primary
port of the LAG.
Brocade(config)# interface ethernet 4/1/4
2. Run the route-only command to disable switching and enable routing on the LAG.
Brocade(config-if-e1000-4/1/4)# route-only
3. Run the ip address command to assign an IP address for the LAG.
Brocade(config-if-e1000-4/1/4)# ip address 25.0.0.2/24
The following example shows the creation and deployment of a dynamic LAG that is used for routing on a FastIron device with Layer 3
image.
Brocade(config)# lag “brocade-LAG” dynamic id 55
Brocade(config-lag- brocade-LAG)# ports ethernet 1/1/1 ethernet 2/1/3 ethernet 3/1/4 ethernet 4/1/4
Brocade(config-lag- brocade-LAG)# primary-port 4/1/4
Brocade(config-lag- brocade-LAG)# deploy
Brocade(config-lag- brocade-LAG)# exit
Brocade(config)# interface ethernet 4/1/4
Brocade(config-if-e1000-4/1/4)# route-only
Brocade(config-if-e1000-4/1/4)# ip address 25.0.0.2/24
