Benefits of The VLAN Trunking Protocol

VLAN Trunking Protocol

VTP is messaging protocol that manages renaming, deletion, and addition of Virtual Local Area Networks. VTP helps to lower the administration in switched networks. Trunk port is used to interconnect the switch or router. Trunks can carry multiple VLANs traffic via a single link.

While using VTP there is no need to configure VLAN everywhere. VLANs will be distributed from VTP server so, the time will be reduced to configure the same VLAN anywhere else.

It will minimize inconsistencies in configuration which can cause problems, like duplicate VLAN names, incorrect VLAN-type specifications, and security violations. With VTP any changes into the configuration can be made centrally on devices and can be communicated to all other network devices automatically.

The following are major benefits of VLAN Trunking Protocol.

VTP is beneficial to maintaining configuration consistency throughout the whole network. VTP utilizes trunk frames for managing any changes made to the VLANs in that network. VTP synchronizes all the VLAN information in any VTP domain by lowering the need of configuring similar VLAN data on every switch.

VLAN Trunking Protocol offers a decent mapping scheme for seamless trunking in an exceeding network that uses mixed media. It lowers the possible inconsistencies in the configuration that normally come about once modifications are made in a network. Such inconsistencies may result in security violations since VLANs have the potential of cross-connecting when matching names are utilized. Furthermore, they might possibly become disconnected internally when mapped from a particular LAN kind to consecutive.

VTP provides an effective method of managing Cisco switches for configuration purposes. If the VTP has been enabled on a Cisco switch, creating a VLAN on one switch then makes the VLAN accessible to all or any of the switches in this VTP domain. The switch can only be a section of 1 VTP domain at one time.

Without VTP, the Network engineer will have to define a new VLAN individually on all necessary Switches which could cause errors and become time-consuming. This can be saved with the creation of a VTPs.
