Chapter13 Configuring VTP
Configuring VTP
Configuring a VTP Client
When 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.
Caution If all switches are operating in VTP client mode, do not configure a VTP domain name. If you do, it is
impossible to make changes to the VLAN configuration of that dom ain. Therefore, make sure you
configure at least one switch as a VTP server.
Beginning in privileged EXEC mode, follow these steps to configure the switch as a VTP client:
Use the no vtp mode global configuration command to return the switch to VTP server mode. To return
the switch to a no-password state, use the no vtp password privileged EXEC comma nd. When you
configure a domain name, it cannot be removed; you can only reassign a switch to a different domain.
Note You can also configure a VTP client by using the vlan database privileged EXEC command to enter
VLAN database configuration mode and entering the vtp client command, similar to the second
procedure under “Configuring a VTP Server” section on page 13-9. Use the no vtp client VLAN
database configuration command to return the switch to VTP server mode or the no vtp password
VLAN database configuration command to return the switch to a no-password state. When you configure
a domain name, it cannot be removed; you can only reassign a sw itch to a different domain.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 vtp mode client Configure the switch for VTP client mode. The default setting is VTP
server.
Step3 vtp domain domain-name (Optional) Enter the VTP administrative-domain name. The name can be 1
to 32 characters. This should be the same domain name as the VTP server.
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) Enter the password for the VTP domain.
Step5 end 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.
