Configuring VTP
You can also configure VTP transparent mode by using the vlan database privileged EXEC command
Note
to enter VLAN database configuration mode and by entering the vtp transparent command, similar to
the second procedure under the
transparent VLAN database 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 when the switches are in VTP server or transparent mode.
VTP Version 1 and VTP Version 2 are not interoperable on switches in the same VTP domain. Every
Caution
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.
For more information on VTP version configuration guidelines, see the
page
Beginning in privileged EXEC mode, follow these steps to enable VTP Version 2:
Command
Step 1

Step 2

Step 3

Step 4

To disable VTP Version 2, use the no vtp version global configuration command.
Note
You can also enable VTP Version 2 by using the vlan database privileged EXEC command to enter
VLAN database configuration mode and by entering the vtp v2-mode VLAN database configuration
command. To disable VTP Version 2, use the no vtp v2-mode VLAN database configuration command.
