VLAN's not replicating over VTP

[#1]

I am introducing a new switch to an existing network, however VLAN's don't appear to be propogating over VTP.

Core Switch - 4506 (192.168.10.1)

New Switch - 3 x 3750's (192.168.10.12)

The two are connected via a trunk:

4506 End:

interface GigabitEthernet2/20
 description -- Link to Test Switch --
 switchport trunk encapsulation dot1q
 switchport mode trunk
 no logging event link-status
 no keepalive
 qos trust cos
end

3750 End:

interface GigabitEthernet3/0/1
 description -- Link to SW_HH-01 --
 switchport trunk encapsulation dot1q
 switchport mode trunk
end

Both are in the same VTP domain. The 4506 is a VTP server, the 3750 stack is a VTP client. There is no authentication on VTP.

I am able to ping each switch from the other, however still the VLAN's aren't replicating.

Can anybody advise what I may be missing?

Thanks,

Neil

Can you post "sh vtp status" from both switches?

Hello Neil,

I know it's probably almost rude to ask you to redo the verification but double-checking these things usually reveals the discrepancy causing these problems:

• show vtp status on both switches: make sure that none of them is in VTP Transparent mode. Further on, make sure that the new switch has a lower revision number. Also verify - once again - the VTP domain name. Is the VTP version identical on both switches?
• show vtp password - make sure that whatever is set, it is set identically on both switches
• show run | include vtp - make sure that no special VTP configurations are put into either of these switches

Best regards,

Peter

Thanks Peter - I had checked the password on the server, but hadn't bothered on the client. For some reason there was a VTP password set. Even though it only came out of the box a few moments ago...

Cheers,

Neil
