I have a Cisco 4507 switch with 20 VLANs and it operates as the VTP server rank is 29 and a new cisco 3750X switch that I need to connect to the cisco 4507 and extend VLAN10 to the new switch and I need some help understanding what I need to do to establish/extend vlan 10 to the new switch.  I understand the VTP Client mode rank needs to be less than the VTP server and so I have set that up as 0 and VTP client so that issue is ready I have selected port to trunk and set encapsulation (if trunking is the best method to extend please advise), are there any other gottchas I need to be aware of?

If you are only extending vlan 10 to the stack.

interface typex/x                                          (connecting the switches on both ends)
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 10

Also make sure your vtp domain and passwords are the same also.

Soulja, Is there a password for the VTP  I thought we could just assign either VTP client or server (in our case client as we already have a master root bridge) but I have not seen a configuration for a password?  Please advise.

Thanks

If there is not password configured for your vtp domain then the new switch will not require one.
