Before You Begin
VTP pruning is not designed to function in VTP transparent mode. If one or more switches in the network
are in VTP transparent mode, you should do one of these:
•
Turn off VTP pruning in the entire network.
•
Turn off VTP pruning by making all VLANs on the trunk of the switch upstream to the VTP transparent
switch pruning ineligible.
To configure VTP pruning on an interface, use the switchport trunk pruning vlan interface configuration
command. VTP pruning operates when an interface is trunking. You can set VLAN pruning-eligibility, whether
or not VTP pruning is enabled for the VTP domain, whether or not any given VLAN exists, and whether or
not the interface is currently trunking.
