mls qos cos COS_NUM work only for tagged frame if you need set priority to
untagged frame you should use switchport priority extend cos COS_NUM

Subject: mls qos trust cos
Should we always use the "mls qos trust cos" when configuring a voice vlan
on the 3550?
Say I want to have all data frame's COS value changed to 1 coming into an IP
phone access port. I would use the "switchport priority extend cos 1".
What if I didn't have the "mls qos trust cos" on the switchport? Would the
switch now use the default for the port and change the COS back to 0?
