Benefits of VLAN Trunking Protocol

VLAN Trunking Protocol

VTP (VLAN Trunking Protocol) may be a Cisco proprietary electronic communication protocol employed by Cisco switches to exchange VLAN data. VTP synchronizes VLAN data (such as VLAN ID or VLAN name) with switches within a similar VTP domain, that greatly simplifies network administration. A VTP domain is solely a group of trunked switches with the matching VTP settings (domain name, parole and VTP version). All switches within a similar VTP domain share their VLAN data with one another.

To better perceive the advantage of victimization VTP in your network, think about Associate in Nursing example network with a hundred switches. while not VTP, to make a VLAN on every switch, you’d ought to manually enter the VLAN creation commands on every switch! VTP allows you to make the VLAN solely on one switch. That switch will then propagate data this VLAN to every switch within the same VTP domain and cause alternative switches to make that VLAN too. Likewise, if you would like to delete a VLAN, you simply have to be compelled to delete it on one switch, and therefore the amendment is mechanically propagated to each alternative switch within a similar VTP domain.VLAN Trunking Protocol or VTP refers to a electronic messaging protocol accountable for managing the renaming, deletion and addition of VLANs

  1. Higher network management

VTP lowers the attainable inconsistencies in configuration that usually ensue once modifications area unit created in a very network. Such inconsistencies might cause security violations since VLANs have the potential of cross connecting once matching names area unit used. what is more, they may presumably become disconnected internally once mapped from a precise local area network kind to consequent. However, VLAN Trunking Protocol offers a decent mapping theme for seamless trunking in a very network that uses mixed media.

  1. Supports consistency

The VLAN Trunking Protocol offers the good thing about keeping configuration consistency throughout the total network. this can be attributable to the very fact that VTP utilizes trunk frames for managing any changes created to the VLANs in this specific network. this can be earned through the employment of a central switch found within the server mode. In fact, VTP synchronizes all the VLAN info in any VTP domain, thereby lowering the requirement of configuring similar VLAN knowledge on each switch.

  1. Manages Cisco switches

Another important advantage of VLAN Trunking Protocol is that it supplies a good technique of managing Cisco switches like one cluster for configuration functions. this implies that if the VTP has been enabled on a Cisco switch, making a VLAN on one switch then makes the VLAN accessible to all or any the switches in this VTP domain. The switch will solely be a region of 1 VTP domain at one time.

The key downside of mistreatment VLAN Trunking Protocol is that iteration will occur. iteration is often terribly annoying because it creates duplicate emails and it’s going to even crash the total network.
