Configuring the Wireless QoS

The Wireless QoS controls priority differentiation for data packets in wireless
egress direction. It includes the following topics:
• Default Wireless QoS Settings, page 150
• Configuring the Wireless QoS Classification Methods, page 151
• Mapping CoS to Wireless Queue, page 151
• Mapping DSCP to Wireless Queue, page 151

Default Wireless QoS Settings

The Wireless QoS uses the default queuing method for wireless traffic. Wireless
traffic is always trusted. The wireless QoS treats all untagged packets as tagged
packets with the default CoS value 0 so that the security appliance can refer to the
CoS to Queue mapping settings to obtain the corresponding wireless egress
queue.
If you enable WMM for the SSIDs, the following table displays the default mapping
settings between DSCP and WMM. The default mapping settings between CoS or
DSCP and WMM cannot be changed, but the default mapping settings between
CoS or DSCP and wireless queues are editable.
