There we go again, I just keep forgettin’ things that every time are obvious. Say you have to change a configuration on a Portchannel interface. How to do it? Since the physical ports must have the same configuration of the Portchannel interface for the Ether Channel to come up there must be a sequence. And ideed there is.
- Change configuration on the physical interfaces in the group
- Change, finally, the configuration on the port channel interface
Long live and prosper.
