'''VLAN Trunking Protocol''' ('''VTP''') is a [[Cisco]] proprietary Layer 2 messaging protocol that manages the addition, deletion, and renaming of [[VLAN]]s on a network-wide basis. Virtual Local Area Network (VLAN) Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new [[VLAN]] on one VTP server, the VLAN is distributed through all switches in the ___domain. This reduces the need to configure the same VLAN everywhere. To do this VTP carries VLAN information to all the switches in a VTP ___domain. VTP advertisements can be sent over [[Cisco Inter-Switch Link|ISL]], [[802.1q]], [[IEEE 802.10]] and LANE trunks. VTP traffic is sent over the management VLAN (VLAN1), so all [[Trunking#VLANs|VLAN trunks]] must be configured to pass VLAN1. VTP is available on most of the Cisco [[Catalyst]] Family products.<ref name="javvin">http://www.javvin.com/protocolVTP.html</ref>
