Summary AdvertisementsД«y default, Catalyst switches issue summary advertisements in five-minute increments. In order to reset the configuration revision of a switch, change the VTP domain name, and then change the name back to the original name. Each time that you make a VLAN change in a VTP device, the configuration revision is incremented by one. This information is used in order to determine whether the received information is more recent than the current version. Most of the VTP packets contain the VTP configuration revision number of the sender. Each VTP device tracks the VTP configuration revision number that is assigned to it. The configuration revision number is a 32-bit number that indicates the level of revision for a VTP packet. But, all VTP packets contain these fields in the header: The format of the VTP header can vary, based on the type of VTP message. In that case, the ISL header and cyclic redundancy check (CRC) is replaced by dot1q tagging. Of course, you can have a VTP packet inside 802.1Q frames. This is the format of a VTP packet that is encapsulated in ISL frames:

These packets are sent to the destination MAC address 01-00-0C-CC-CC-CC with a logical link control (LLC) code of Subnetwork Access Protocol (SNAP) (AAAA) and a type of 2003 (in the SNAP header). VTP packets are sent in either Inter-Switch Link (ISL) frames or in IEEE 802.1Q (dot1q) frames. Refer to one of these sections of VLAN Trunking Protocol (VTP) for more information: VTP Version 3 differs from VTP V1 and V2 and is only available on CatOS 8.1(1) or later. Note:В This document does not cover VTP Version 3. Refer to Cisco Technical Tips Conventions for more information on document conventions.

This document is not restricted to specific software or hardware versions.

There are no specific requirements for this document. Make certain that you understand the differences between VTP Version 3 and earlier versions before you alter your network configuration. VTP Version 3 incorporates many changes from VTP V1 and V2. 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 is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products. This reduces the need to configure the same VLAN everywhere. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain.

VLAN Trunk Protocol (VTP) reduces administration in a switched network.
