The priority-map tunnel-upstream trust command configures a trusted priority type used in mapping from 802.11 packets to tunnel packets when packets are sent to the AC from an AP.
The undo priority-map tunnel-upstream trust command restores the default trusted priority type used in mapping from 802.11 packets to tunnel packets when packets are sent to the AC from an AP.
By default, the 802.11e priority is used in mapping from 802.11 packets to tunnel packets when packets are sent to the AC from an AP.

Usage Scenario
To provide QoS guarantee for data packets of different users when packets are transmitted over a tunnel, configure a specific tunnel priority or priority mapping.
802.11 packets sent from a WMM-capable STA carry the user priority (Layer 2) or DSCP priority (Layer 3), and tunnel packets carry the 802.1p priority (Layer 2) or tunnel DSCP priority (Layer 3). 802.11 packets sent to the AC from an AP must be converted into tunnel packets.
You can run the priority-map tunnel-upstream trust command to configure a trusted priority type used in mapping from 802.11 packets to tunnel packets when packets are sent to the AC from an AP.
Precautions
The tunnel priority mapping is applicable to scenarios where data packets are sent in tunnel forwarding mode.
