From my understanding, Channel-misconfig errors usually indicate
inconsistent channel paramters with the peer switch. So you need to look at
the other switch, not the one you get the error from, and confirm that the
parameters are all the same. Also, make sure that the allowed VLAN list is
the same on both sides of the trunk.
