No .. As server mode

You can configure normal-range VLANs (2 through 1000) when the switch is in either VTP server or transparent mode. However, you can only configure extended-range VLANs (1025 through 4094) in VTP transparent switches.

But mode is Server ... :(

Doesn't matter. Extended vlans are only supported in transparent mode.

I am trying to add VLAN "2"

Sorry my fault, I thought you were adding vlan 1003. Here's a link that describes the problem and the resolution. Let us know if that fixes it.

Anyone have ay idea about this?

Thanks

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

Hi,

Can u just try to create a dummy vlan and see.

Thanks

Mahmood

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.
