Enabling or Disabling
Wireless Multi-media
/interface/wifi-<n>-<m>/set qos wmm {enable|disable}
Wireless Multi-media is normally enabled. It allows the access point to
communicate with a WMM enabled wireless client using WMM features.
When disabled, the access point ignores requests for WMM communications
from wireless clients and instead uses traditional non-WMM features to
communicate with them. To disable WMM, you must first disable Unscheduled
Automatic Power-save Delivery (UAPSD). See
Power-save Delivery” on page 166
.
QoS Mapping Scheme
/interface/wifi-<n>-<m>/set qos mapping {up|dscp|both}
The
set
command lets you decide how traffic is processed to the four BelAir
priority queues depending on the values of the User Priority (UP) field or the
Differentiated Services Code Point (DSCP) subfield in the client traffic fields.
Selecting
up
means that traffic is sent to the four BelAir priority queues based
on the UP field value. Selecting
dscp
means that traffic is sent to the four BelAir
priority queues based on the DSCP subfield value. Selecting
both
means that
traffic is sent to the four BelAir priority queues based on the highest priority
value of either the UP field or the DSCP subfield. By default, QoS mapping is set
to
both
.
shows the mapping of the UP value and the DSCP value to
the priority queue.
