VLAN Trunking Protocol

Overview of VTP
VTP is a Layer 2 messaging protocol that maintains VLAN configuration consistency by managing the
addition, deletion, and renaming of VLANs within a VTP domain. A VTP domain (also called a VLAN
management domain) is made up of one or more network devices that share the same VTP domain name
and that are interconnected with trunks. VTP minimizes misconfigurations and configuration
inconsistencies that can result in a number of problems, such as duplicate VLAN names, incorrect
VLAN-type specifications, and security violations.

Before you create VLANs, you must decide whether you want to use VTP in your network. With VTP,
you can make configuration changes centrally on one or more network devices and have those changes
automatically communicated to all the other network devices in the network. For details on configuring
VLANs, see
