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 will enable version 2 as
well.
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.
To enable VTP version 2, perform this task in privileged mode:
This example shows how to enable VTP version 2 and verify the configuration:
Console> (enable) set vtp version 2
This command will enable VTP version 2 function in the entire management domain.
All devices in the management domain should be version2-capable before enabling.
