Hi,
I need to setup a Catalyst 3500XL switch to support VoIP phones. Please look at a snippet of my config:
Fa0/1 will connect to my Cisco router setup as a router on a stick.
Fa0.2 will connect to my shoretel Voip Switch
and all remaining ports will be configured to connect to a Shoretel IP phone and the PC will connect off of the Shoretel Phone set.
VLAN1 is the native for PC users and VLAN24 is for VoIP traffic.
Does this look okay?
Regards
Jeff

This may work if you don't need computers behind the phones.
For that you will need something more like this for your phone/PC ports:
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 1
switchport access vlan 24
Then you will need to either manually program all the Shoretel phones to use VLAN 24 and pass native VLAN through switchport or find a way to do this via DHCP.

You are correct. I configured and this is working correctly.
interface FastEthernet0/24
switchport trunk encapsulation dot1q
switchport mode trunk
switchport priority default 1
switchport voice vlan 24
spanning-tree portfast
!
Thank you
Jeff
