Disabling VTP (VTP Transparent Mode)
When you configure the switch as VTP transparent, you disable VTP on the switch. A VTP transparent
switch does not send VTP updates and does not act on VTP updates received from other switches.
However, a VTP transparent switch running VTP version 2 does forward received VTP advertisements
out all of its trunk links.
To disable VTP on the switch, perform this task in privileged mode:
Task
Step 1
Place the switch in VTP transparent mode
(disabling VTP on the switch).
Step 2
Verify the VTP configuration.

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 also will enable version 2.
