[c-nsp] 2950 QoS

[info at beprojects.com]

Does anybody know what commands are necessary to enable layer2 QoS on a 
2950?  I've read:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/12122ea5/2950scg/swqos.htm

and it really doesn't help much.  I've got Cisco phones that are getting 
tagged and I just want their traffic to have priority.  I've read that 
"mls qos trust cos" will "trust" the QoS on ingress, but what about 
egress?  I don't see anything about that and that's what I need.  Maybe 
it's just on by default??  Thanks for any help.
