preconfigure new 2960 switches with vlans to join existing switch & VTP Domain

I currently have a 3750 stack that's role is the VTP Server & have configured a VTP Domain. In addition there are 10 2960 in VTP Client roles attached by fiber trunk ports. I have configured 15 VLANS on the VTP Server which successfully propagated to the clients.

I now have 9 new 2960s that I want to preconfigure as VTP Clients under the existing VTP Domain and assign their access ports to 1 of the 15 already existing VLANs.

My goal is to plug my 9 preconfigured new 2960s via fiber trunk port into the existing network.

Is this possible and if so how?

Thank you adrianuta2004 & eeRoot. But just to be sure here is what I believe we are all saying:

Existing Network:

one 3750 - (VTP Mode: Server, VTP Domain: MyDomain, VTP Password: MyPassword, 15 VLANs created locally)

ten 2960 - (VTP Mode: Client, VTP Domain: MyDomain, VTP Password: MyPassword, 15 VLANs advertised from 3750)

(All the above switches are connected to each other via fiber trunk ports)


Nine additional 2960s to be Preconfigured as such:

2960Switch(config)#vtp mode server (cannot create VLANs while in Client Mode)
2960Switch(config)#vtp domain MyDomain (from existing network)
2960Switch(config)#vtp password MyPassword (from existing network)
2960Switch(config)#int vlan 10
2960Switch(config-if)#int range f0/1-48
2960Switch(config-if-range)switchport mode access
2960Switch(config-if-range)switchport access vlan 10
2960Switch(config-if-range)exit
2960Switch(config)#vtp mode client
2960Switch(config)#do wr

Now connect new 2960 to existing network and everything runs fine right?

Or do I leave the nine 2960s at vtp mode server until after their joined then switch them to vtp mode client?

you must have at least one interface configured as trunk. VTP only works on trunk ports.

Yes, I stated in my comment dated 08/11/11 02:18 PM:

(All the above switches are connected to each other via fiber trunk ports)

and the additional nine 2960s will be connected with trunks ports as well (e.g.):

2960Switch(config)#int f0/1
2960Switch(config-if)#no switchport access
2960Switch(config-if)#switchport mode trunk
2960Switch(config-if)#no shut
2960Switch(config-if)#exit
2960Switch(config)#do wr

And of course a similar configuration on either end of the trunk (switchport trunk dot1q encap on the 3750).

But you have not answered my last comment dated 08/11/11 02:18 PM. Is that the correct procedure?
