| 2.8 |  | VTP Configuration and VTP Pruning |
| 2.8.2 |  | Configuring the VTP version |

Two different versions of VTP can run in the management domain, VTP Version 1 and VTP Version 2. The two versions are not interoperable in the same VTP domain. The major difference between the two versions is version 2 introduces support for Token Ring VLANs.

If all switches in a VTP domain can run VTP Version 2, version 2 only needs to be enabled on one VTP server switch. The version number is propagated to the other VTP Version 2-capable switches in the VTP domain. Version 2 should not be enabled unless every switch in the VTP domain supports version 2.

The VTP version can be configured from global configuration mode or VLAN database mode on a Cisco IOS-based switch. From there, the VTP version can be changed with the vtp command.

VTP Configuration in global configuration mode:

> Switch#config terminal
> Switch(config)#vtp version 2

VTP Configuration in VLAN configuration mode:

> Switch#vlan database
> Switch(vlan)#vtp v2-mode
