I have a Cisco 6509, where we are doing port channels/aggregating ports to a HP chassis. In any case during the initial setup we made some extra port groups. And being the good admin I wanted to clean up the extra port channels.
Well right after I took the ports out of the port-channel all hell broke loose. And the switch stopped traffic everywhere.
I think it was around the time when I put a command no channel-group while in a range of ports. By the way these ports only go to a HP chassis nothing was running on it at the time. I am attaching the log from the putty. The only thing after the fact that I noticed is that I did a no channel-group without a channel-group number. But I would hope that it wouldn't crash from that and at worst just not accept the command. Any thoughts are more then welcome. But the real question is whether what I did caused it or did something else happen. I am running IOS 12.2 and other then another port channel to another HP chassis we don't have any others. And it took out all network traffic not just to the port channels.
