It appears you currently have both switches configured as VTP Servers, change one of then to be a client. Also verify your VTP domain/password are the same on both devices

Dose not make any difference if I make I one server and other client (yes.. I was not able to create any VLAN in Client mode)....

Domian name is correct too... bc if change VTP domain name I am getting this error... Also there is no authentication....

00:03:34: %DTP-5-DOMAINMISMATCH: Unable to perform trunk negotiation on port Fa0

/11 because of VTP domain mismatch.

Hi,

I try to the same thing but I am getting this same error (Add o Remove Vlans).

http://www.cisco.com/en/US/tech/tk389/tk689/technologies_configuration_example09186a008009478e.shtml#vlan1003

This document say that possible cause are:

VTP version mismatch, but this switch are configured VTP version 2 and VTP Mode Transparent.

Because the VTP mode is Transparent the VLAN information is store on Startup-config and Vlan.dat, I erase the flash:vlan.dat and reload the switch.

Later when the switch are online, I was able to create and delete Vlans.
