Changing VTP Version 3 Modes

For more information on VTP version modes, see the
Note
Each database is propagated by an instance of the VTP protocol. As these instances are independent, they
can operate in different modes. The set vtp mode command allows you to set the mode for a particular
VTP instance. The VTP instance is identified by the name of the feature to which it applies. The set vtp
mode command has been extended to include a feature that you specify to identify the database to which
the command applies. The unknown keyword allows you to configure the behavior of the switch
databases that it cannot interpret. (These databases will be features handled by future extensions of VTP
version 3.) If you enter the set vtp mode transparent unknown command, the packets for the unknown
features are flooded through the switch. If you enter the set vtp mode off unknown command, the packets
are dropped. The "unknown" feature can only be configured with off or transparent modes. The default
mode is off for all databases. The mode of the VLAN database and MST database are preserved when
VTP versions are changed.
Note In software releases 8.1(x) and 8.2(x), the only supported database propagation is for the VLAN
database; therefore, there are no "unknown" databases. In software release 8.3(1), support is added to
propagate the MST database.
Configuring a VTP Version 3 Server
When a switch is in VTP version 3 server mode, you can change the VLAN configuration and have it
propagate throughout the network. To configure the switch as a VTP version 3 server, perform this task
in privileged mode:
Task
Step 1 Define the VTP domain name.
Step 2 Place the switch in VTP server mode.
Step 3 (Optional) Set a password for the VTP domain.
Step 4 Verify the VTP configuration.
This example shows how to configure the switch as a VTP VLAN server and verify the configuration:
