priority-map downstream trust

priority-map downstream trust

Function

The priority-map downstream trust command configures a trusted priority type used in mapping from 802.3 packets to 802.11 packets when packets are sent to an RU from upper-layer devices.

The undo priority-map downstream trust command restores the default trusted priority type used in mapping from 802.3 packets to 802.11 packets when packets are sent to an RU from upper-layer devices.

By default, the DSCP priority is the trusted priority type used in mapping from 802.3 packets to 802.11 packets when packets are sent to an RU from upper-layer devices.

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). On a wired network, VLAN packets carry the 802.1p priority and IP packets carry the DSCP priority. When data packets are forwarded from the central AP or other upper-layer devices to an RU, the packets must be converted from 802.3 packets to 802.11 packets.

You can run the priority-map downstream trust command to configure a trusted priority type used in mapping from 802.3 packets to 802.11 packets when packets are sent to an RU from upper-layer devices.

Example

# In traffic profile p1, configure the 802.1p priority as the trusted priority type used in mapping from 802.3 packets to 802.11 packets when packets are sent to an RU from upper-layer devices.
