VTP reducesadministration in a switched network. When you configure a new VLAN on one VTP server, the VLAN isdistributed through all switches in the domain. This reduces the need to configure the same VLANeverywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst seriesproducts.PrerequisitesRequirementsThere are no specific requirements for this document.Components UsedThis document is not restricted to specific software and hardware versions.ConventionsRefer to Cisco Technical Tips Conventions for more information on document conventions.Understand VTPRefer to Understanding VLAN Trunk Protocol (VTP) for more information on VTP.

VTP Configuration GuidelinesThis section provides some guidelines for the configuration of VTP in the network.All switches have the same the VTP domain name, unless the network design insists for differentVTP domains.Note: Trunk negotiation does not work across VTP domains. Refer to the Data Traffic Blockedbetween VTP Domains section of Troubleshooting VLAN Trunk Protocol (VTP) for moreinformation.All switches in a VTP domain must run the same VTP version.All switches in a VTP domain has the same VTP password, if there is any.All VTP Server switch(es) should have the same configuration revision number and it should also bethe highest in the domain.When you move a VTP mode of a switch from Transparent to Server, VLANs configured on the VTPTransparent switch should exist on the Server switch.VTP Configuration on Catalyst SwitchesThis section provides some basic commands in order to configure VTP on the most commonly used Catalystswitches.Note: The Catalyst 2948G-L3 and Catalyst 4908G-L3 Layer 3 (L3) switches do not support several Layer 2(L2)-oriented protocols that are found on other Catalyst switches. Such protocols include VTP, DTP, and PortAggregation Protocol (PAgP).Catalyst 6500/6000 Series Cisco IOS Software/Catalyst 4500/4000 CiscoIOS Software (Supervisor Engine III/Supervisor Engine IV), Catalyst 2950,3550, and 3750 Series SwitchesThere are two methods that you can use in order to configure VTP, as this section shows. Method 2 (theglobal configuration mode method) is not available in earlier software on Catalyst 6500 series switches thatrun Cisco IOS® Software.
