Ideas:
1) Bad cables or cable
2) Fiber/TX
3) make sure there is no udld enabled (just to make sure) (global etc).
4) Try port channel with one interface configured on both sides. See if this
works.
Here is what I do to remove the problem (besides what's mentioned above) : shut
all interfaces down. configure the port channel. bring one side up. bring the
other side up.

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?
