Configuring a VTP Client
When a switch is in VTP client mode, you cannot change the VLAN configuration on the switch. The
client switch receives VTP updates from a VTP server in the management domain and modifies its
configuration accordingly.
To configure the switch as a VTP client, use the following commands beginning in privileged EXEC mode:
Command
Step 1
Router# vlan database
Step 2
Router(vlan)# vtp client
Step 3
Router(vlan)# exit
Disabling VTP (VTP Transparent Mode)
When you configure the switch as VTP transparent, you disable VTP on the switch. A VTP transparent
switch does not send VTP updates and does not act on VTP updates received from other switches.
However, a VTP transparent switch running VTP version 2 does forward received VTP advertisements
out all of its trunk links.
To disable VTP on the switch, use the following commands beginning in privileged EXEC mode:
Command
Step 1
Router# vlan database
Step 2
Router(vlan)# vtp transparent
Step 3
Router(vlan)# exit
Configuring VTP version 2
To enable VTP version 2, use the following commands beginning in privileged EXEC mode:
Command
Step 1
Router# vlan database
Step 2
Router(vlan)# [no] vtp v2-mode
Step 3
Router(vlan)# exit
