Configure the Cisco Access Point switch ports as well as any uplink switch ports for trust DSCP.
Below is a sample switch configuration for an access point:
mls qos
!
interface X
mls qos trust dscp
Note: When using the Cisco Unified Wireless LAN Controller, DSCP trust must be implemented or trust the UDP data ports
used by the Cisco Unified Wireless LAN Controller (LWAPP = 12222 and 12223; CAPWAP = 5246 and 5247) on all
interfaces where wireless packets will traverse to ensure QoS markings are correctly set. Versions prior to 5.2 use LWAPP,
where versions 5.2 and later use CAPWAP.
Configuring Cisco IOS Access Points
Use the following QoS policy on the Cisco IOS access point (AP) to enable DSCP to CoS (UP) mapping. This allows packets to
be placed into the proper queue as long as those packets are marked correctly when received at the access point level.
