Chapter 13 Configuring VTP
Configuring VTP
Beginning in privileged EXEC mode, follow these steps to configure VTP transparent mode and save
the VTP configuration in the switch startup configuration file:
To return the switch to VTP server mode, use the no vtp mode global configuration command.
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.
Note
You can also configure VTP transparent mode by using the vlan database privileged EXEC command
to enter VLAN configuration mode and by entering the vtp transparent command, similar to the second
procedure under the
“Configuring a VTP Server” section on page 13-9
. Use the no vtp transparent
VLAN configuration command to return the switch to VTP server mode. 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.
Enabling VTP Version 2
VTP version 2 is disabled by default on VTP version 2-capable switches. When you enable VTP
version 2 on a switch, every VTP version 2-capable switch in the VTP domain enables version 2. You
can only configure the version on switches in VTP server or transparent mode.
Caution
VTP version 1 and VTP version 2 are not interoperable on switches in the same VTP domain. Every
switch in the VTP domain must use the same VTP version. Do not enable VTP version 2 unless every
switch in the VTP domain supports version 2.
Note
In TrCRF and TrBRF Token ring environments, you must enable VTP version 2 for Token Ring VLAN
switching to function properly. For Token Ring and Token Ring-Net media, VTP version 2 must be
disabled.

Name fields of the display.
Step 5
