DSCP Mapping
Wi-Fi Multimedia
The Wi-Fi Multimedia (WMM) standard defines voice, video, best effort, and background access categories that can be given different performance priorities on the wireless network. To be effective, these priorities must then align with the QoS, or traffic prioritization, scheme configured for the wired network.
To bridge the two, Differentiated Service Code Point (DSCP) values provide a way to map WMM priorities to QoS treatments.
Juniper Mist APs will overwrite existing DSCP values of upstream traffic using its own Access Categories (AC) values. The original DSCP values are not retained.
You can enable WMM under the QoS Priority section in the WLANs page.
For information about navigating to the WLANs page, see Navigating to the WLANs Page.
The DSCP to AC mappings are given in the tables below.

| 0 (Background) | DSCP CS2 (0x40) |
| 1 (Best Effort) | DCSP CS3 (0x60) |
