Enabling VTP pruning on a VTP server enables pruning for the entire management domain. VTP pruning
takes effect several seconds after you enable it. By default, VLANs 2 through 1000 are pruning eligible.
VTP pruning does not prune traffic from pruning-ineligible VLANs. VLAN 1 is always pruning
ineligible; traffic from VLAN 1 cannot be pruned.
To configure VTP pruning on a trunking LAN port, use the switchport trunk pruning vlan command
(see the
