Configuring Enhanced Virtual Port Channels
This example shows how to verify the consistency of the port channel numbering between the two switches.
In this example, the port channel numbering is inconsistent and the member ports are suspended:
switch-1# show running-config interface Ethernet110/1/1, Ethernet111/1/1
!Command: show running-config interface Ethernet110/1/1, Ethernet111/1/1
!Time: Sun Aug 28 03:38:23 2011
version 5.1(3)N1(1)
interface Ethernet110/1/1

switch-2# show running-config interface Ethernet110/1/1, Ethernet111/1/1
!Command: show running-config interface Ethernet110/1/1, Ethernet111/1/1

Verifying Common Port Channel Members
The port channel from a FEX to the switch pair is up and operational when there is at least one common port
channel member between the two switches. Any FEX interfaces that are assigned to the port channel only on
one switch will be suspended.
SUMMARY STEPS
1. show port-channel summary
2. (Optional) show interface type/slot
