When you implement voice vlan and data vlan, do you need a multilayer switch? I am planning to have the voice and the shoretel sg-12 switch in one vlan and the data and its server in another vlan. Can this be accomplish with just a layer 2 switch? Thx

The vlans can be implemented with a layer2 switch (a "vlan" or "802.1q" capable swich, which is almost any "managed" switch).
Routing traffic between the vlans would need either a layer3 switch, or a router.

I understand. But my question is do I need layer 3 switch to implement voice vlan and data vlan. I am not a voice guy so I am not sure what to look for. Thx

Basically, no. The "voice vlan" is a plain simple vlan, with 2 optional features:
- the switch advertises it through CDP/LLDP, so the IP phone can configure itself to use the voice vlan, instead of the data vlan,
- and the switch might automatically provide some QoS services for the voice vlans. Procurve switches usually do that by default.

My smallest voice deployment is a Catalyst 3500XL layer2 switch, with one data and one voice vlan. The routing between the vlans is provided by a Cisco 2650.

I see. I am using DHCP server for my IP phones and laptops. I guess I can use an external router for the IP Phone to get to the dhcp server. Thx

Depending on your server, you could do the routing with that. It's easy on Linux, a bit more tricky with Windows.

Simple answer is NO. If you want traffic to pass between the two vlans you will need a layer 3 device to route that traffic.
