Configuring VTP Version 3 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 that are received from other
switches.
Note Network devices in VTP transparent mode do not send VTP join messages. On Catalyst 6500 series
switches with trunk connections to network devices in VTP transparent mode, you should configure the
VLANs that are used by the transparent-mode network devices or that need to be carried across trunks
as pruning ineligible (use the clear vtp pruneeligible command).
To disable VTP on the switch, perform this task in privileged mode:
This example shows how to configure the switch as VTP VLAN transparent and verify the configuration:
Console> (enable) set vtp mode transparent vlan

Disabling VTP Using the Off Mode
When you disable VTP using the off mode, the switch behaves the same as in VTP transparent mode
with the exception that VTP advertisements are not forwarded.
To disable VTP using the off mode, perform this task in privileged mode:
