What is VTP pruning Cisco?

VLAN Trunking Protocol (VTP) pruning is a feature in Cisco switches, which stops VLAN update information traffic from being sent down trunk links if the updates are not needed. VLAN Trunking Protocol (VTP) pruning helps in increasing the available bandwidth by reducing unnecessary flooded traffic.

What does VLAN not pruned mean?

VLAN Trunking Protocol (VTP) pruning is a feature in Cisco switches, which stops VLAN update information traffic from being sent down trunk links if the updates are not needed.

Which VLAN number is never eligible for VTP pruning?

VLAN 1
VLAN 1 is never pruning eligible, because it is a factory-default VLAN. VLANs 1002 to 1005 are reserved for token ring networks. The VLANs 1006 and above require VTP version 3 to be pruning eligible.

What does V stand for in VTP?

Understanding VLAN Trunk Protocol (VTP) – Cisco.

What is STP pruning?

A pruning method can be implemented on Cisco switches to prune VLANs from going to switches that do not have any hosts for that VLAN. It is important to note that although pruning can prevent some unnecessary traffic from being circulated across the network, pruning VLANs does not simplify the spanning-tree topologies.

How do I stop VTP from pruning?

Note: VTP Pruning is disabled by default on all Cisco Catalyst switches and can be enabled by issuing the “set vtp pruning enable” command. If this command is issued on the VTP Server(s) of your network, then pruning is enabled for the entire management domain.

What is the purpose of trunking in VLAN?

The main purpose of trunking is to carry traffic between switches and maintain the VLAN information. Unlike an access link, the trunk link does not belong to a single VLAN but instead can carry traffic from several VLANs over a point-to-point link between two devices that understand the protocol.
