Herr Stout,
Another easy way of determining if the problem is with the port or the
cable would be to plug both ends of the cat 5 cable(s) into a cable
tester. The manner Mike proposes is legit but I would want to
positively know that all pairs are 100%. Once you certify the cable as
being good, then the port would probably be the problem. Hopefully it
will be the cable...helluva lot cheaper!

The only way I can think that it would be a cable problem is if
there was a
short in the wire somewhere. Unplug the CAT5 from the suspect
port, do a
shut/no shut do you get the same result? Better still plug a PC
into the
port, does it stay up/up? Then plug a PC in another port with an
FTP server
on it and do some file transfers, then check for errors.
