The MD5 digest between the VTP Server located on Switch1 and the VTP Client located on Switch2 have been synchronized.

Although the steps from this Q&A have been followed, a trunk has been created between VTP Client Switch3 and VTP Server Switch1, a discrepancy in MD5 digest remains and the VLANs created on Switch1 do not appear on Switch3.

Follows ASAP



interface GigabitEthernet0/X
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate


interface GigabitEthernet0/Y
 switchport mode trunk
 switchport nonegotiate

Note: trunk type is required on Cisco IOS 3560 and encapsulation dot1q is not available on Cisco IOS 2950

  • Can you post the output of "show vtp status" from both switches? Jul 15 '14 at 19:27
  • VTP Server configuration has been added. The other configuration follows ASAP as the switches reside on the work.

The basic answer to your question is no, the different switch versions don't matter. As long as you're running the same VTP version on the server and client, both are configured for the same VTP domain and password (optional), and the link between switches uses 2 correctly-configured trunk ports, you should be good to go.

  • After synchronizing the VTP version it works with one trunk link
