Configuring VTP
Enabling VTP Version 2
VTP Version 2 is disabled by default on VTP Version 2-capable switches. When you enable VTP
Ve r s io n
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.
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 14-8.

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.
