Hi Ryan,
As far I as know, unless the interface that you are going to configured "mls
qos trust cos" is a trunk or it's not making any different.
Example,
Usually you will see this for cisco IP-phone configuration in order to
implement QoS on access-layer.
Would anyone clarify my concept is correct or not? =)
Cheers~
Jacky
