Configuring a VTP Version 3 Takeover
For additional details, see the
Note
Use the set vtp primary [feature] [force] command to configure a takeover. The takeover mechanism
allows a secondary server to become a primary server and propagates the primary server's configuration
to the entire VTP domain, removing any partitions if applicable.
If a password was configured using the hidden keyword, you are prompted to reenter it.
Note
If the force keyword is not specified, the switch first tries to discover some conflicting servers in the
domain. Conflicting servers are servers that follow a different primary server than the one in the
configuration of the local switch. You are prompted by the local switch for confirmation before
proceeding with the takeover. The prompting is necessary because taking over the domain involves
overwriting the configuration of any conflicting servers.
If the optional feature keyword is not specified, the local switch sends a takeover message for each
database for which it is a secondary or a primary server. If a database is specified, the switch takes over
only those databases that are associated with the specified feature.
Note
In software release 8.1(1), the only supported database propagation is for the VLAN database.
To configure a takeover, perform this task in privileged mode:

Enter VTP password:
No conflicting VTP 3 devices found.
