I have a Cisco 3640 and apparently I'm a moron. 12.1 IOS, 4 T's in it, nothing special, all internal routing. Had a modem card and group sync interface in config. Shut down that group sync interface completely and removed the card, replaced with a network mod with two wics. I can see/configure the two new wics, but the group sync interface still resides in the configuration. How do I go about removing the interface. Not really hurting anything, just would like to have it gone just to make it look clean. Thoughts?
