After power comes up, 3640 eth is not working

After a power outage, the eth port in our 3640 is not working. I just need to unplug and plug back in the net cable, and everything is ok.

It's not that eth0 is shutdown or else.

Is that a bug?

3640

C3640-IS-M), Version 12.0(4)T, RELEASE SOFTWARE (fc1)

2 T1 WIC cards

It could be becoz the the other end may be having incompatible in negotiating duplex,speed...set them as per the other end.Or Check whether the keep alive is set to zero.
