VTP Configuration Commands

How do I disable VTP?

To disable VTP, enter the set vtp domain domain name mode transparent command. This disables VTP from the domain, but does not remove the domain from the switch. Use the clear config all command to remove the domain from the switch. Be careful when you use the clear config all command.

Is VTP enabled by default?

VTP version 2 is disabled by default. After you have enabled version 2 on one switch, all other switches in the domain also begin to operate in version 2 mode.

What is VTP used for?

VTP is a protocol used to distribute and synchronize identifying information about VLANs configured throughout a switched network. Configurations made to a single VTP server are propagated across trunk links to all connected switches in the network.

What is a VTP mode?

VTP server mode (Cisco) VTP servers advertise their VLAN configurations to other switches in the same VTP domain and synchronize their VLAN configurations with other switches based on advertisements received over trunk links. VTP server is the default mode.

How do I configure VTP mode?

Configuring basic VTP on CISCO Switches

1. Step 1 – Creating a VTP Server. VTP has the following 3 different modes:
2. Step 2 – Configuring a switch as a VTP client. Enter configuration mode and use the following commands to enable client mode.
3. Step 3 – Configure native and trunking VLAN.
4. Step 4 Testing VTP.

How do I reset my VTP revision number?

To reset the VTP revision number to zero, use the following two options:

1. Change the switch’s VTP domain to a nonexistent VTP domain, and then change the domain back to the original name.
2. Change the switch’s VTP mode to transparent and then back to the previous VTP mode.

What is a VTP domain?

A VTP domain is a set of trunked switches with the matching VTP settings (the domain name, password and VTP version). All switches inside the same VTP domain share their VLAN information with each other. To better understand the true value of VTP, consider an example network with 100 switches.

How do I turn off VTP?

Why VTP is needed?

Cisco’s VLAN Trunking Protocol (VTP) provides an easier method for maintaining consistent VLAN configuration throughout the switched network. VTP is a protocol used to distribute and synchronize identifying information about VLANs configured throughout a switched network.

Why do we need VTP?

VTP is CISCO proprietary protocol used to maintain consistency throughout the network or user can say that synchronizing the VLAN information in same VTP domain. VTP allows you to add, delete and rename VLANs which is then propagated to other switches in the VTP domain.

What is the difference between Cisco VTP v1 v2 and V3?

VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products. Note: This document does not cover VTP Version 3. VTP Version 3 differs from VTP Version 1 (V1) and Version 2 (V2), and it is only available on Catalyst OS (CatOS) 8.1 (1) or later. VTP Version 3 incorporates many changes from VTP V1 and V2.

What is VTP server mode?

Server—In VTP server mode, you can create, modify, and delete VLANs and specify other configuration parameters, such as VTP version and VTP pruning, for the entire VTP domain.

Does VTP create unnecessary traffic?

However, there are occasions when VTP can create unnecessary traffic. All unknown unicasts and broadcasts in a VLAN are flooded over the entire VLAN. All switches in the network receive all broadcasts, even in situations in which few users are connected in that VLAN.

What should I pay attention to when using VTP?

When you use VTP, there are two things to which you must pay close attention: Remember the configuration revision and how to reset it each time that you insert a new switch in your network so that you do not bring down the entire network. Avoid as much as possible to have a VLAN that spans the entire network.
