Configure LA

Language:

This task describes how to configure and test the LA feature of SEFOS running on a switch target.

See Switching Feature Topology for the topology of this task.

Configure the initial settings.
See Configure Initial Settings.

Create a port-channel group 100 on SEFOS-1 and link the ports in the group.

SEFOS-1# configure terminal
SEFOS-1(config)# set port-channel enable
SEFOS-1(config)# interface port-channel 100
SEFOS-1(config-if)# no shutdown
SEFOS-1(config-if)# exit
SEFOS-1(config)# interface range xl-ethernet 0/1-2
SEFOS-1(config-if)# no shutdown
SEFOS-1(config-if)# channel-group 100 mode active
SEFOS-1(config-if)# exit
SEFOS-1(config)# vlan 101
SEFOS-1(config-vlan)# ports xl-ethernet 0/1-2 port-channel 
SEFOS-1(config-vlan)# ports xl-ethernet 0/25-26 port-channel 100 untagged xl-ethernet 0/25-26 port-channel 100

Repeat Step 2 on SEFOS-2.

Verify the VLAN membership.

SEFOS-1# show vlan
Vlan database

Vlan ID : 101
Member Ports : X10/25,X10/26,po100
Untagged Ports : X10/25,X10/26,po100
