Product and Software: This article applies to ArubaOS 3.1.1.x and 3.3.2.x.
If your device supports WMM, you can verify the WMM counters with the 'show ap debug client-stats [MAC Address]' command. A sample output is shown here. Please note the WMM receive counters. Depending on the WMM receive value, the TSO DSCP value will be set.

*********************************************
In release 3.1.1.x, you can map the WMM/AC values to the following DSCP value. You must verify that the correct COS is configured on the core switches for the assigned DSCP value.
UP WMM AC DSCP
7 AC_VO 0x38
6 AC_VO 0x30
5 AC_VI 0x28
4 AC_VI 0x20
3 AC_BE 0x18
2 AC_BK 0x10
1 AC_BK 0x08
0 AC_BE 0x00
*********************************************
In release 3.3.1.x, you can assign the WMM/AC value to the DSCP value that is configured on the core switches. Here is a sample profile:
