Configuring VTP
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.
For more information on VTP version configuration guidelines, see the “VTP Version” section on
page 11-8.
Beginning in privileged EXEC mode, follow these steps to enable VTP version 2:
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 entering the vtp v2-mode VLAN database configuration
command. To disable VTP version 2, use the no vtp v2-mode VLAN database configuration command.
