I'm attempting to migrate 15 or so VTP servers over to two VTP servers and 13 VTP clients. I renamed the domain and set a password. I created and deleted a VLAN a couple times to crank the revision number up on the new server. Upon doing this, VLAN 1 shuts down. I backed out my changes, and plugged a PC into an access port on VLAN1 and it comes back up. I re-attempted this work again with a device plugged in to an Access port on VLAN1 and I experience the same issue. I have a TAC case open, however I was wondering if anyone else ran into this issue. IOS version on the switch is c3750-ipservicesk9-mz.122-25.SEB4. Looking for any ideas. Thanks in advance.
