How does one find the VTP ver3 primary server?

In VTP ver3, you can only create VLANs on the primary server. If I walk into an unknown environment, how do I know which server is the primary server?

sh vtp devices

This command only works with VTP ver 3 and will list all devices participating in VTP. In this list each device's "VTP Device ID" is shown along with the primary server for each device.

Thx. That worked.

Another way of looking at it is at how VTPv3 acts compared to VTPv2. While it's been a bit since I've messed around with VTPv3, but the following cisco documentation should prove useful for you.

You have to call Cisco TAC.

That or use the command you use to find other VTP status information.
