Keep in mind upstream and downstream are different.
Upstream am if the client doesn't mark avc will mark the traffic on the wlc then place on wired. That said it has no qos over the air or on the way to the wlc.
Downstream am the wlc will mark, so long as qos is configured properly it should be dropped into the propert queue at the ap and take advantage of the smaller cW.

The administrator is also flexible while configuring Action as MARK to choose the Differentiated Services Code Point (DSCP) value as Custom instead of selecting “Platinum/Gold/Silver/Bronze”. Once Custom is selected as DSCP value, a text filed will be visible where admin can enter a custom DSCP value in range of 0 - 63.
The Next step will be to apply these AVC profiles on the WLAN. Only one AVC profile can be mapped to a single WLAN. A single AVC profile can be mapped to multiple WLANs. Once an AVC profile is mapped to a WLAN and if it has a rule for MARK action, that application will get precedence as per QoS profile configured in AVC rule interacting with the QOS profile configured on the WLAN. All the AVC profiles created will be visible under AVC Profile drop-down in WLAN under QOS TAB. To see the AVC profile in the drop-down on WLAN, navigate to WLANs > WLAN ID and then click QOS tab. All the AVC profiles created are visible under the AVC Profile drop-down. The administrator can select the AVC profile on the WLAN as per network requirement.
