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

hi,
yes it should unless someone changed the MAC address with the interface command mac-address xxxx.xxxx.xxxx
To verify just do sh run interface G0/1

Thanks for the post, it seems the router has a ROM problem in the controller for the port then.
interface GigabitEthernet0/1
