When a switch is in VTP server mode, you can change the VLAN configuration and have it propagated throughout the network.

Beginning in privileged EXEC mode, follow these steps to configure the switch as a VTP server:

	Command	Purpose
Step 1	configure terminal	Enter global configuration mode.
Step 2	vtp mode server	Configure the switch for VTP server mode (the default).
Step 3	vtp domaindomain-name	Configure the VTP administrative-domain name. The name can be from 1 to 32 characters. All switches operating in VTP server or client mode under the same administrative responsibility must be configured with the same domain name.
Step 4	vtp passwordpassword	(Optional) Set the password for the VTP domain. The password can be from 8 to 64 characters. If you configure a VTP password, the VTP domain does not function properly if you do not assign the same password to each switch in the domain.
Step 5	end	Return to privileged EXEC mode.
Step 6	show vtp status	Verify your entries in the VTP Operating Mode and the VTP Domain Name fields of the display.

When you configure a domain name, it cannot be removed; you can only reassign a switch to a different domain.

To return the switch to a no-password state, use the no vtp password global configuration command.
