Purpose
Enter global configuration mode.
(Optional) Set the password for the VTP domain. The password can be 8 to
64 characters.

•
The secret password must contain 32 hexadecimal characters.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save the configuration in the startup configuration file.

Change the operational state of a switch from a secondary server (the
default) to a primary server and advertise the configuration to the domain.
If the switch password is configured as hidden, you are prompted to reenter
the password.
(Optional) vlan—Select the VLAN database as the takeover feature.
•
This is the default.
(Optional) mst—Select the multiple spanning tree (MST) database as
•
the takeover feature.
(Optional) force—Entering force overwrites the configuration of any
•
conflicting servers. If you do not enter force, you are prompted for
confirmation before the takeover.
