Hello all,
Last week we had a VLAN temporarily shut down on our core 3750 stack after it's name was updated; no other changes were made, the name was simply udpated from the default VLANXXXX to a more user friendly convention; as soon as this occurred the VLAN shutdown unexpectedly and had to be brought back up. This VLAN was only in use in one other building on 2 different 3750 stacks; I've tried to duplicate the scenario in a lab enviornment with the same IOS, running configs, and VLAN database as the production network swtich stacks that were affected but have not been successful in reproducting the behavior; I revisted the IOS guide for this particular switch and could not find any notes or warnings in relation to renaming a VLAN. The core stack is running 12.2.46SE (VTP server) while the affected stacks (and VTP clients) are running 12.2.53SE. Any ideas as to why this may have occurred would be helpful.
