Enabling Vtp Version 2 - Cisco Catalyst 3750 Software Configuration Manual

Chapter 11 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.
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.
In TrCRF and TrBRF Token ring environments, you must enable VTP version 2 for Token Ring VLAN
Note
switching to function properly. For Token Ring and Token Ring-Net media, VTP version 2 must be
disabled.
