The configuration varies by switch. See below for variations.

Cat 4k/6k

set vlan 10 5/1

set port auxiliaryvlan 5/1 11

Catalyst 3500 and Etherswitch module

switchport mode trunk

switchport trunk encapsulation dot1q

switchport trunk native vlan 10

switchport voice vlan 11

Catalyst 3550/3560

switchport access vlan 10

switchport voice vlan 11

Hope this helps. If so, please rate the post.

Hi There, thanks for that, what if I have say 4 different data vlans on the same switch for each dept for example? what would i do here as they all cant be native ?

This is a per port configuration, so 1 vlan will be native on each port.

On a trunk port, you can set the vlans that are allowed with the following command.

switchport trunk allowed vlan

If you ? after this command, you will see that you have several options for allowing vlans.

Hope this helps.
