Your standard QoS mappings would map a DSCP of EF to a COS of 5, but under 802.11e a DSCP of EF is mapped to a COS of 6. Really the best way to configure your switches is to trust DSCP on everything except the ports going to the WLC itself. You can trust DSCP on all ports but the recommendation is to trust COS on the WLC port. This is assuming you are tagging all of the interfaces on the controller that you want to run QoS on.
No, you want to trust DSCP at the AP. Assuming the AP's are in local mode the AP is sending all traffic out a single VLAN tunneled back to the controller. Because of this there isn't a dot1q tag and therefore no CoS bits are avaiable. So if you trust COS on an AP port you will never get a match.

The 1st installment is a table of advanced filters. More filters will be added as time allows.
