Sorry for confusion there. I am referring to the inbound/upstream DSCP value, not on the wireless side. The wireless side will not have a WMM value, though it is put in the same queue as WMM BE traffic.
For DSCP, a non-WMM client will have its DSCP value used (with a markdown similar to 802.11e being marked down - except for EF :) ) up to the QoS Profile and 802.1p value settings (I know - why would the 802.1p value affect DSCP??? It does.) That is for WMM Allowed on a WLAN. And, since non-WMM clients can't use UP values, ACM will not apply to them. If WMM is Disabled on a WMM, all clients (WMM and non-WMM) will have their packets DSCP values marked based on the QoS Profile (and up to the 802.1p value for the Profile.) For instance, on a Platinum QoS Profile WLAN with WMM Disabled (and with 802.1p value of 6,) all packets will be marked EF. If it is Gold with 802.1p 5, packets will be marked AF41.
