Multi VLAN on Cisco 3500

I'm trying to configure a Cisco 3524 XL Switch to replace a defective HP 2650.
On the HP, I just assign which VLANs to the port I wnat it on and assign one of the VLANs as a 'default' (data not tagged entering the port has the default VLAN added).
I have two VLANs, 20 DATA and 30 PHONES. On the HP, I have the ports set so VLAN 20 is the 'default' and VLAN 30 is 'tagged' (the phones tag data for VLAN 30). This means data traversing the switch is tagged with it's required VLAN.

How do I 'tell' the CISCO which is the port's 'default' VLAN and that VLAN 30 will already be tagged?
