Configure LA

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 extreme-ethernet 0/21-22
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 extreme-ethernet 0/1-2 port-channel 
100 untagged extreme-ethernet 0/1-2 port-channel 100

Repeat Step 2 on SEFOS-2.

Verify the VLAN membership.

SEFOS-1# show vlan
Vlan database

Vlan ID : 101
Member Ports : Ex0/1,Ex0/2,po100
Untagged Ports : Ex0/1,Ex0/2,po100
Forbidden Ports : None
Reflective-Relay : Disabled
Name :
Status : Other

Verify the STP port status on SEFOS-1.

Ping continuously from host A to host C.
There should not be any data loss during traffic forwarding.

Verify the port channel summary.
