Configuring Cisco Switch Ports

Configure the Cisco access point switch ports and uplink switch ports for DSCP trust.
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 Switch Ports for Wired IP Phones

Enable the Cisco wired IP phone switch ports for Cisco phone trust

If DSCP markings are not preserved, then the below configuration can be used to set the DSCP based on the TCP or UDP port
to map RTP and SIP correctly.
Ensure the following QoS policy is not applied to an interface where wireless traffic traverses.
If using non-secure SIP, then TCP/UDP port 5060 is used. TCP/UDP port 5061 is used for secure SIP.
