If the client is not a WMM client, the WLAN override (as configured at the controller) determines the 802.11e
queue (bronze, gold, platinum, or silver), on which the packet is transmitted.
For a client of a mesh access point, there are modifications made to incoming client frames in preparation for
transmission on the mesh backhaul or Ethernet. For WMM clients, a MAP illustrates the way in which the
outer DSCP value is set from an incoming WMM client frame.
Figure 78: MAP to RAP Path
The minimum value of the incoming 802.11e user priority and the WLAN override priority is translated using
the information listed in Table 37: DSCP to Backhaul Queue Mapping, on page 175 to determine the DSCP
value of the IP frame. For example, if the incoming frame has as its value a priority indicating the gold priority,
but the WLAN is configured for the silver priority, the minimum priority of silver is used to determine the
DSCP value.

If there is no incoming WMM priority, the default WLAN priority is used to generate the DSCP value in the
outer header. If the frame is an originated CAPWAP control frame, the DSCP value of 46 is placed in the
outer header.
With the 5.2 code enhancements, DSCP information is preserved in an AWPP header.
