FastEthernet is up, line protocol is down
Posted on 2005-04-15
I have a Cisco router (IOS12.1) with two FastEthernet interfaces (as well as BRI and Serial) one of which I can no longer connect with.
I did a "show int fastethernet" and it is showing FastEthernet is up but line protocol is down. It looks like it's been down over a week (from last input/output stats).
What could this be an indication of? An unplugged cable, bad interface...? Should I do a shutdown, no shutdown to try to bring it back up? Could I loose the config doing that?
I don't have local access to the router at present.
As always, any help is greatly appreciated.
