[c-nsp] Cisco 7200 - IOS15.1 - Port-channel

[Billy Guthrie]

Jason,

Very possible that you ran into a bug; I would try removing 
channel-group from the FastE interfaces, remove the port-channel 
interfaces, add the port-channels back in and then add the channel-group 
back onto the FastE interfaces.

Good luck
Billy
