VTP pruning

VTP pruning enables you to limit the amount of traffic sent on trunk ports. It limits the distribution of flooded frames to only switches that have members of the particular VLAN. You can enable VTP pruning with this command:

vtp pruning

When we enable pruning on the switch, all VLANs are pruned by default (with the exception of VLAN 1). You need to configure pruning on only one VTP server, and the setting automatically propagates. You can change this behavior by making select VLANs you choose pruneineligible. This is done with the following command:

switchport trunk pruning vlan {none {{add except remove} vlan[,vlan[,vlan[,...]]}}
The Cisco IOS command is as follows:
