switch(config)# interface port-channel 2
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 100
switch(config-if)# exit
switch(config)# interface ethernet 1/19
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 100
switch(config-if)# channel-group 2
switch(config-if)# exit
switch(config)# interface ethernet 1/20
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 100
switch(config-if)# channel-group 2
switch(config-if)# exit
switch(config)# interface ethernet 1/21
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 100
switch(config-if)# channel-group 2
switch(config-if)# exit
switch(config)# interface ethernet 1/22
switch(config-if)# switchport mode fex-fabric
switch(config-if)# fex associate 100
switch(config-if)# channel-group 2
switch(config-if)# exit
