Hello, I am trying to figure out the behavior of something but having some difficulty getting a conclusive answer. We have 4 ports connecting two Catalyst switches connected via an LACP etherchannel. Yesterday, someone mistakenly misconfigured one of the ports as an access port, changing it from trunk. This brought that one link out of the etherchannel to an up/down state at which time multiple devices on the network experienced connectivity issues -- presumably because of the etherchannel load balancing, their link went down while other devices continued using the other 3 links without issue. Am I correct in thinking that? If so, would those devices that lost connectivity ever recover automatically? I would assume they should have recovered almost immediately, but such was not the case. Is there some kind of stored load-balancing table with a timeout? Was the MAC Address table still pointing to the etherchannel interface for things so after 5 minutes the stale entry would time out and connectivity would be restored? In our case, I was immediately notified of the erroneous change and reverted the interface back to a trunk which corrected the issue, but I'm curious about the details. Thanks!
