A little more information is needed.
Have you assigned IP's to the vlan?
Have you assigned an IP to the 2950?

from what to what are you trying to connect?

I have a Cisco PIX 506 with a vlan configured (DMZ). Behind this PIX is a Cisco Catalyst 2950. I need the Catalyst to handle the vlan because the PIX cannot do this. So I need to know how to configure the vlan on the Catalyst.
The commands to create a VLAN on the catalyst 2950 are all documented here :

Switch(Config)#vlan 3
Switch(Config-vlan)#name DMZ

That will create a VLAN with a VLAN ID of 3 and a name of DMZ on the switch.

You then need to tell the switch what ports are going to access this VLAN :

Switch(Config)#interface fa0/1
Switch(Config-if)#switchport mode access
Switch(Config-if)#switchport access vlan 3

You will need to do this for every device that is going to be a member of that VLAN.
I am guessing that because it is a DMZ you are not going to need that VLAN anywhere else so you won;t need to worry about trunking or anything.

See how you get on.....

I followed the instructions as above but then I can only connect to one vlan on the Cisco.

I have the Cisco PIX connected to interface fa0/5. The Cisco PIX 506 is configured with vlan1 (interface) and vlan2 (logical). Now I need to connect with both of them on interface fa0/5 of the Cisco Catalyst 2950.

Can you post the configs of both devices so we can take a look, Not entirely sure what you are trying to acheive!

I am trying to setup a DMZ with a Cisco PIX and a Cisco Catalyst 2950. Now I put a trunk on interface fa0/5 (Cisco PIX). On this interface it will connect to the both vlan's on the PIX. On interface fa0/3 (DMZ) I put vlan 2 interface. Now i am able to ping the Cisco PIX from the DMZ and from the inside. Only i am not able to use the internet on the DMZ.

So the question has been a little bit changed. Can i ask this question here or do i need to open a new one?
Go for it! Ask away....

I can ping the Cisco PIX 506 on the vlan from the DMZ. Only i have no internet connection from the DMZ. Here is the config from the PIX.

It could be something to do with your NAT setup. You have NAT running for the inside interface but nothing for the DMZ.
The 10.x.x.x will not be able to get routed on the internet....
