Cisco Cisco IOS Software Release 12.2(55)SE

By default, all devices come up as secondary servers. Primary server status is needed only for database 
updates when the administrator issues a takeover message in the domain. You can have a working VTP 
domain without any primary servers. 

Primary server status is lost if the device reloads or domain parameters change.

This example shows how to configure the switch as the primary VTP server for VLANs:

Switch# vtp primary vlan

This sytems is becoming primary server for feature vlan.

You can verify your settings by entering the show vtp status privileged EXEC command.

Displays the VTP statistics for the switch and general information about the 
VTP management domain status.

Configures the VTP filename, interface, domain name, mode, and version.
