Small site with half a dozen 12.2 IOS switches 3550, 2960, 4506. All are running VTP version 2 with the 4506 as the server. When adding a new 2960 switch with a blank revision number, configured to use v2, the version changes to v1 when it is added as a client. I've rechecked to ensure all other switches are running v2, verified that I'm using the same domain name and password, but can't determine why the version is changing. Any ideas?
