Chapter 18 Configuring VTP
Configuring VTP
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.
This example shows how to use global configuration mode to configure the switch as a VTP server with
the domain name eng_group and the password mypassword:
Switch# config terminal
Switch(config)# vtp mode server
Switch(config)# vtp domain eng_group
Switch(config)# vtp password mypassword
Switch(config)# end
You can also use VLAN configuration mode to configure VTP parameters. Beginning in privileged
EXEC mode, follow these steps to use VLAN configuration mode to configure the switch as a VTP
server:
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 VLAN configuration command.
Step 4
vtp password password (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.
Command Purpose
Command Purpose
Step 1
vlan database Enter VLAN configuration mode.
Step 2
vtp server Configure the switch for VTP server mode (the default).
Step 3
vtp domain domain-name Configure a 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 password password (Optional) Set a 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
exit Update the VLAN database, propagate it throughout the administrative
domain, and 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.
