Hi,

The problem here is that I suspect that the channel-group was created before the interfaces were configured as fex-fabric interfaces, and consequently the channel-group is not specified as a fex-fabric port-channel.  The simplest solution without have to remove the port-channel, is to simply go under the port-channel inferace and specify 'switchport mode fex-fabric', then go back under the physical interface and add the channel-group again.

Regards

Allan.
