This can't be right, it's on our 2951:


GigabitEthernet0/0 is up, line protocol is up
Hardware is PQ3_TSEC, address is f866.f2dd.8820 (bia f866.f2dd.8820)

GigabitEthernet0/1 is down, line protocol is down
Hardware is PQ3_TSEC, address is f866.f2dd.8820 (bia f866.f2dd.8821)

It's connected to a switch with a Port-channel to both the above ports on the router and the switch is logging MAC flapping errors with the f866.f2dd.8820 MAC as the source.
 
Then port channel is not working correctly and it thinks they are separate ports and it is complaining about it .
 
I don't have another router to compare with, but shouldn't g0/1 have the same MAC listed for it's MAC and the bia?

That's the question I had.
