Once upon a time there was a (Layer 2) port-channel5, consisting of two Gigabit-Ethernet interfaces Gi10/11 and Gi10/12. Then, after a considerable time I noticed, that it had changed its name to "port-channel5A" although it was still configured as port-channel5.
Then there was an interruption between the two ends. The two Gigabit-Ethernet interfaces went down for about 30 Seconds - and so did port-channel5A. Then Gi10/11 came up again, but Gi10/12 didn't. 5 Seconds later port-channel5 came up (yes, 5, not 5A)
I've removed Gi10/12 from the port-channel, because I'm a bit concerned by this behaviour. What'll happen if I bundle the two Gig-Ports again? Will there be a disruption (will Po5 go down and reappear as Po5A?). I'm not keen on another interruption since it is a vital link between two organizations. And the main question is: what caused the channel to become 5A?
Configuration of the channel is quite straightforward:
