Chapter 13 Configuring VTP
Configuring VTP
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 domain. 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 global configuration command. 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 configuration mode and entering the vtp client command, similar to the second procedure under

Disabling VTP (VTP Transparent Mode)
When you configure the switch for VTP transparent mode, VTP is disabled on the switch. The 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 on its trunk
links.

Note
Before you create extended-range VLANs (VLAN IDs 1006 to 4094), you must set VTP mode to
transparent by using the vtp mode transparent global configuration command. Save this configuration
to the startup configuration so that the switch boots up in VTP transparent mode. Otherwise, you lose
the extended-range VLAN configuration if the switch resets and boots up in VTP server mode (the
default).
