Re: vtp query

Hi Amy,

VTP Configuration Guidelines

This 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 different VTP domains.Note: Trunk negotiation does not work across VTP domains. Refer to the Data Traffic Blocked between VTP Domains section of Troubleshooting VLAN Trunk Protocol (VTP) for more information.

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 be the highest in the domain.

When you move a VTP mode of a switch from Transparent to Server, VLANs configured on the VTP Transparent switch should exist on the Server switch.


for background info on VTP also have a look at

I've seen several Cisco documents recommending against the use of VTP client and VTP server mode. Misconfiguration can lead to overwriting of the local VLAN database on switches. This will cause outages in your network.

For example see the Cisco Press book Designing Cisco Network Service Architectures for details.
