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.
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 a Token Ring environment, you must enable VTP version 2 for Token Ring VLAN switching to
function properly.
For more information on VTP version configuration guidelines, see the “VTP Version” section on
page 8-11.
