Chapter 14 Configuring VTP
Configuring VTP
Configuring a VTP Server
When a switch is in VTP server mode, you can change the VLAN configuration and have it propagated
throughout the network.
Note If extended-range VLANs are configured on the switch, you cannot change VTP mode to server. You
receive an error message, and the configuration is not allowed.
Beginning in privileged EXEC mode, follow these steps 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 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 database configuration mode to configure VTP parameters.
Beginning in privileged EXEC mode, follow these steps to use VLAN database configuration mode 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 domain domain-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 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
Step 1
vlan database Enter VLAN database configuration mode.
Step 2
vtp server Configure the switch for VTP server mode (the default).
