Unable to understand the laguage written above,But as per the log check the vtp domain configured in server and rest of the switches.It should be same in order to work.

Hi,


A VTP domain is made up of one or more interconnected network devices that share the same VTP domain name. A network device can be configured to be in only one VTP domain.


I think you are trying to configure more than 1 vtp domain on single device

I configured VTP domain in two network different, One relied in 6506 and other in 4506

Configuration 6506: Domain toto, vtp mode server, VTP V2 Mode, VTP Pruning Mode Enabled

Configuration 4506: Domain titi, vtp mode server, VTP V2 Mode, VTP Pruning Mode Enabled


Thanks

You have a trunk link between 6500 and 4500, which is making VTP traffic to flow across and leading the mismatch of VTP domain

As hitesh pointed the right thing you have trunk link between the two switches, If your VTP domains do not match on each side of a trunk link, then DTP will NOT work.  You need to watch out for this as the ports will be up/up, but trunking will not be negotiated.  You’ll need to either make both VTP domains the same, or hard-set the trunks with “switchport nonegotiate”.


Hope to Help !!
