What is the use of VTP pruning?
It is key element of VTP (Vlan Turning Protocol). It help improves network performance and network bandwidth by decreasing unnecessary flooded traffic i.e. broadcast, multicast, unknown and flooded unicast packets.
What is pruning in STP?
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.
What is VTP and how it works?
VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used by Cisco switches to exchange VLAN information. VTP enables you to create the VLAN only on a single switch. That switch can then propagate information about the VLAN to every other switch on the network and cause other switches to create it.
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.
Why is STP used?
Spanning Tree Protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when computers exchange data on a local area network (LAN) that contains redundant paths.
What is VLAN pruning and why is it a good practice?
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 being pruned mean?
Frequency: The definition of a prune is a partially dried plum, or is slang for an ill-tempered and unpleasant person. An example of a prune is a Casselman. An example of a prune is someone who gets angry when told to stop playing in the traffic.
What does pruning mean in networking?
Pruning is the process of deleting irrelevant parts of a belief network before invoking inference.
What is STP and VTP?
VLAN Trunking Protocol (VTP) is a Cisco proprietary protocol that propagates VLAN on the whole local area network. VTP carries VLAN information to all the switches in a VTP domain. Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Local Area Networks.
Is VTP pruning enabled by default?
What is Pvst?
Per VLAN Spanning Tree (PVST) is a Cisco proprietary protocol that allows a Cisco device to have multiple spanning trees. The Cisco device can interoperate with spanning trees on other PVST devices but cannot interoperate with IEEE 802.1Q devices. An IEEE 802.1Q device has all its ports running a single spanning tree.
What is VTP transparent mode?
The VTP Transparent mode is something between a VTP Server and a VTP Client but does not participate in the VTP Domain. In Transparent mode, you are able to create, modify and delete VLANs on the local switch, without affecting any other switches regardless of the mode they might be in.
What is VLAN Trunking Protocol (VTP) domain?
A VLAN Trunking Protocol (VTP) domain is one switch or several interconnected switches sharing the same VLAN Trunking Protocol (VTP) environment. A switch can be configured only in one VLAN Trunking Protocol (VTP) domain.
What is VTP domain?
The VTP Domain. A VTP domain (also called a VLAN management domain) consists of one switch or several interconnected switches under the same administrative responsibility sharing the same VTP domain name. A switch can be in only one VTP domain.
