priority-map downstream dot1p

priority-map downstream dot1p

Function

The priority-map downstream dot1p command configures mapping from 802.1p priorities of 802.3 packets to user priorities of 802.11 packets when packets are sent to an RU from upper-layer devices.

The undo priority-map downstream dot1p command restores the default mapping from 802.1p priorities of 802.3 packets to user priorities of 802.11 packets when packets are sent to an RU from upper-layer devices.

By default, 802.1p priority 0 of 802.3 packets maps to user priority 0 of 802.11 packets, 802.1p priority 1 to user priority 1, and similarly, 802.1p priority 7 to user priority 7.

Format

priority-map downstream dot1p { dot1p-value1 [ to dot1p-value2 ] } &<1-7> dot11e dot11e-value

undo priority-map downstream dot1p

Parameters

Parameter

Description

Value

dot1p dot1p-value1

Specifies the 802.1p priority in an 802.3 packet.

The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority.

to dot1p-value2

Specifies the 802.1p priority in an 802.3 packet.

The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority.

dot1p-value2 must be greater than dot1p-value1.

dot11e dot11e-value

Specifies the 802.11 user priority.

The value is an integer that ranges from 0 to 7. A larger value indicates a higher priority.

Usage Guidelines

802.3 and 802.11 packets use different fields to identify their priorities. 802.11 packets sent from a WMM-capable STA carry the user priority (also called the User Priority field), and VLAN tagged-802.3 packets transmitted on the Ethernet contain 802.1p priorities (also called the CoS field). When data packets are forwarded from the central AP or upper-layer network to an RU, the RU needs to convert the 802.3 packets to 802.11 packets and map the 802.1p priority carried in the 802.3 packet header to the user priority of 802.11 packets. You can use the priority-map downstream dot1p command to configure mapping from 802.1p priorities of 802.3 packets to user priorities of 802.11 packets.

Example

# Configure the mapping from 802.1p priorities of 802.3 packets to user priorities of 802.11 packets in traffic profile p1.
