Hi Kiran,

I had some problems too, after creating a VTP domain name and password I was
able to get this working. Also check to see if your trunk interfaces is up
and running.

This is my setup:

SW1:

SW1#sh vtp st
SW1#sh vtp status
VTP Version : 2
Configuration Revision : 1
Maximum VLANs supported locally : 256
Number of existing VLANs : 16
VTP Operating Mode : Server
VTP Domain Name : RS
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x65 0xBE 0xDA 0x0B 0x23 0x77 0xCA 0xEA
Configuration last modified by 192.1.112.11 at 3-1-02 00:03:34
Local updater ID is 192.1.20.11 on interface Vl20 (lowest numbered VLAN
interface found)

SW1#sh vlan-switch
