Hello,

what exactly was the problem ?

Here are the configurable options for VTP in CatOS:

set vtp

To set the options for VTP, use the set vtp command.

set vtp domain domain_name

set vtp mode {client | server | transparent | off} [vlan | mst | unknown]

set vtp passwd passwd [hidden]

set vtp pruning {enable | disable}

set vtp version {1 | 2 | 3}

set vtp primary [vlan | mst] [force]

Check this link to the command reference:

set vtp

Sounds like a switch got inserted with a higher version number . Before installing a new switch in the same domain you "must" make sure the revision number is lower on the switch before installing it if you are running a client/server model. Any easy way to do that is to change the domain name to something other than the current domain name and then change it back to the one you are using and this will reset the revision number to "0" and you will never have a problem . I don't think there is a command to manually set the version other than the above but someone can correct me if I'm wrong.
