Chapter13 Configuring VTP
Configuring VTP
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.
This example shows how to use VLAN configuration mode to configure the switch as a VTP server with
the domain name eng_group and the password mypassword:
Switch# vlan database
Switch(vlan)# vtp server
Switch(vlan)# vtp domain eng_group
Switch(vlan)# vtp password mypassword
Switch(vlan)# exit
APPLY completed.

Configuring a VTP ClientWhen a switch is in VTP client mode, you cannot change its VLAN configuration. The client switch
receives VTP updates from a VTP server in the VTP domain and then modifies its configuration
accordingly.
Note If extended-range VLANs are configured on the switch, you cannot change VTP mode to client. You
receive an error message, and the configuration is not allowed.
Command Purpose
Step1 vlan database Enter VLAN configuration mode.
Step2 vtp server Configure the switch for VTP server mode (the default).
Step3 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.
Step4 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.
Step5 exit Update the VLAN database, propagate it throughout the administrative
domain, and return to privileged EXEC mode.
Step6 show vtp status Verify your entries in the VTP Operating Mode and the VTP Domain Name
fields of the display.
