The priority-map tunnel-upstream dot11e dot1p command configures mapping from user priorities of 802.11 packets to 802.1p priorities of tunnel packets when packets are sent to the AC from an AP.
The undo priority-map tunnel-upstream dot11e dot1p command restores the default mapping from user priorities of 802.11 packets to 802.1p priorities of tunnel packets when packets are sent to the AC from an AP.
By default, user priority 0 of 802.11 packets maps to 802.1p priority 0 of tunnel packets, user priority 1 to 802.1p priority 1, and similarly, user priority 7 to 802.1p priority 7.

Parameter |
Description |
Value |
|---|---|---|
dot11e dot11e-value1 |
Specifies the user priority of 802.11 packets. |
The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority. |
to dot11e-value2 |
Specifies the user priority of 802.11 packets. |
The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority. dot11e-value2 must be greater than dot11e-value1. |
dot1p dot1p-value |
Specifies the 802.1p priority of tunnel packets. |
The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority. |
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 user priorities (Layer 2 priorities) or DSCP priorities (Layer 3 priorities). Tunnel packets carry 802.1p priorities (Layer 2 priorities) or DSCP priorities (Layer 3 priorities). When data packets are sent from APs to the AC, 802.11 packets need to be converted to tunnel packets.
You can run the priority-map tunnel-upstream dot11e dot1p command to configure mapping from user priorities of 802.11 packets to 802.1p priorities of 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.
# In traffic profile p1, map user priority 6 of 802.11 packets to 802.1p priority 1 of tunnel packets when data is sent from APs to the AC.
