I'm doing some L2 cleanups across mutliple 6509E environments and I've found something consistent that I can't find in documentation.
On all my pairs of 6509s where I have FWSMs bundled (6509-A has FWSM-1 is Slot 1 and 6509-B has FWSM-2 in Slot 1) I also have a port channel 305. Obviously when I do a "show run" or "show int desc" I don't see anything in slot one. It's a service module. But the port channel is referencing ports 1/1-6. And it's all in service/up. I was about to delete this as I thought it was some leftover config (TEST 6509s) until I went and saw the same things on our PROD 6509s. Can anyone explain this or provide some documentation on it? Is it cosmetic? Necessary? Can I delete it as part of my audit cleanup? Don't want to mess with it even in TEST without some information. Nothing on google that's clear and I can't find anything on CCO.
