Usage Guidelines
A VTP primary server updates the database information and sends updates that are honored by all devices in
the system. A VTP secondary server can only back up the updated VTP configurations received from the
primary server to NVRAM.
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 command is supported only when the device is running VTP Version 3. Note
Examples This example shows how to configure the device as the primary VTP server for VLANs:
Device# vtp primary vlan
Setting device to VTP TRANSPARENT mode.
You can verify your settings by entering the show vtp status privileged EXEC command.
