Layer 2 qos

Hello,

I am trying to understand setting layer 2 cos on user interface. I have a machine that is connected to cisco 3550 on access port. I would like to set cos 5 on all the traffic that is coming out on this interface. I read in order to chance cos on packet you need 801.2q tag. I am thinking that the only way to get this tag is from a trunked port? But my user port is access port. Can this be done by just going to the access port and setting the cos on the interface? I did this but i am not sure if this is working because I am reading that the port has to be using 801.2q? Or can I use MQC and match the interface and then set the dscp value for all traffic coming out this interface?
