is pruned.
Switch 6
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 2–1000 are pruning eligible. VTP
pruning does not prune traffic from VLANs that are pruning ineligible. VLAN 1 is always pruning
ineligible; traffic from VLAN 1 cannot be pruned.
To make a VLAN pruning ineligible, enter the clear vtp pruneeligible command. To make a VLAN
pruning eligible again, enter the set vtp pruneeligible command. You can set VLAN pruning eligibility
regardless of whether VTP pruning is enabled or disabled for the domain. Pruning eligibility always
applies to the local device only, not for the entire VTP domain.
