Cisco 3560 switches not seeing VTP V3

I have setup VTP on Cisco switches dozens of time, but these two switches have me stumped.  And I am SURE I am just not seeing my configuration error, so I just need another set of eyes.

I have two Cisco 3560 switches.

They are connected together through port interface GigabitEthernet 1/1 on both switches.

After configuring both switches and typing the command #show vtp devices

I get a return message of "No VTP3 devices found"

Here is the VTP configuration on the server switch (3560-A)

interface GigabitEthernet1/1
 description LAN connection to 3560-B.
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 10
 switchport trunk allowed vlan 10,20,30
 switchport mode trunk


Here is the VTP configuration on the client server switch (3560-B)

interface GigabitEthernet1/1
 description LAN connection to 3560-A.
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 10
 switchport trunk allowed vlan 10,20,30
 switchport mode trunk

Here is the VTP status of each switch:

VTP Password is : cisco123 on both switches

Does anyone see my configuration error?

Thank you in advance,

Is the trunk port up?
sh int trunk

Hello SIM50.

Yes, they are on both sides, and traffic is flowing beautifully.  I have NO problems with passing packets over the trunk ports.  Just that one problem with VTP.

Here are the sh int trunk command results
3560-A (VTP Server) (I have other trunk ports on this switch but the Gig1/1 is the only one connected to a switch)

Gi1/1       on               802.1q         trunking      10

have you tried debug vtp?
Could it be because you are missing primary vtp server?

Hi Shark Attack,

No I have not.  However, what that suggestion tells me is that you do not see anything wrong with my configuration.  Which is where I though the problem was.  

I am not all that keen on the Cisco debugger...it is not very user friendly.  But I will try turn it on for "events" and see if anything is there.
SIM50,

You may be on to the problem there.  I had not seen that.  However, I do not know even where to set that.  I have never had to hard code that previously.  One you enter "vtp mode server vlan", I have always seen it just pick up the Primary ID from the Device ID.  

Do you know the CLI to hard set that?

BTW, I am running c3560e-ipbasek9-m  version 15.0(2)SE8 of the IOS

Thank you,

SIM50,

I get an error on that command.  "vtp primary vlan" is NOT available as a command with the latest version of IOS I am using apparently.

3560-A(config)#vtp primary vlan
                                     ^
% Invalid input detected at '^' marker.

3560-A(config)#vtp ?
  domain     Set the name of the VTP administrative domain.
  file       Configure IFS filesystem file where VTP configuration is stored.
  interface  Configure interface as the preferred source for the VTP IP updater
             address.
  mode       Configure VTP device mode
  password   Set the password for the VTP administrative domain
  pruning    Set the administrative domain to permit pruning
  version    Set the administrative domain to VTP version

3560-A(config)#

SIM50,

Sorry, I did not realize where I was.  As you can see from the sh vtp stat, the Primary ID is now set.

That DID fix my issue!

I had not had to set that parm before.  But once I did, the sh vtp devices DO show up.

Thank you!
This solution fixed the problem 100%.  Thank you SIM50!
Anytime.
