The new switch was setup transparent. I don't see any topology changes in the network. I can understand adding the new switch and have the network re converge. The weird part is powering down a switch that does not touch the phone system taking it down is weird.

A new switch running VTP server mode, can wipe everything on your network in the right circumstances (configured with matching vtp domain name, and having a higher revision than the existing network). Not sure about the switch removal, unless it was a VTP master :) Jeff _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
