My initial troubleshooting would hover around spanning tree issues. LOOPS,
ROOT etc...

Subject: peculiar etherchannel issue
I have two identically configured 6500s with the same IOS code. If I
configure a two port ether-channel with either LACP or PAGp to a remote
switch with the first 6500 everything works fine. If I do it with the second
6500 the port-channel interface comes up and stays up for about a minute
before the remote switch detects an etherchannel misconfiguration and puts
both ports into err-disabled state. I've tried it with three different
remote switches and I get the same result. It works with the one 6500, but
not the other. If I clear the error the link comes back up but repeats the
same process. I've tried different physical ports on the 6500, same result.
Has anyone seen anything like that before?
