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)#
