We have to do this on all of our Cisco Port-channels that lead to Brocade ICX switches: no spanning-tree etherchannel guard misconfig If we don't do it, after a couple of days, the Cisco will err-disable the Port-channel just as you describe. I guess the misconfig detection is incompatible with the Brocade OS. We have seen no ill effects from this, as we are using "mode active" on all our Port-channels. So if there is a misconfiguration, the LAG does not come up for that port on either end, and we're good. Hope that helps. -- -- Hunter Fuller Network Engineer VBH Annex B-5 +1 256 824 5331 Office of Information Technology The University of Alabama in Huntsville Systems and Infrastructure
