WM Access Domain Services configuration
Summit WM User Guide, Software Version 5.3204
Configuring the priority override
Priority override allows you to define the desired priority level. Priority override can be used with any
combination, as shown in Table 24. You can configure the service class (L2 override) and the DSCP
values (L3 override values).
When Priority Override is enabled, the configured service class overrides the queue selection in the
downlink direction, the 802.1P UP for the VLAN tagged Ethernet packets, and the UP for the wireless
QoS packets (WMM or 802.11e) according to the mapping in Table 23. If Priority Override is enabled
and the WM-AD is not locally bridged, the configured DSCP value is used to tag the IP header of the
encapsulated packets. The AP does not override the DSCP in the IP header of the user packet.
Working with Quality of Service (QoS)
QoS policy is configured for each WM-AD and applies to routed, bridged at AP, and bridged at
controller WM-ADs.
Each WM-AD has a configurable policy for the QoS characteristics of the WM-AD. For every user
associated with the WM-AD there will be a different behavior on the wireless traffic.
NOTE
Active QoS is only applied on the wireless/802.11 domain, not on the wired domain.
QoS modes
You can enable the following Qos modes for a WM-AD:
z Legacy - If enabled, the AP will classify and prioritize the downlink traffic for all clients according to
the same rules used for the WMM and 802.11e.
z WMM - If enabled, the AP will accept WMM client associations, and will classify and prioritize the
downlink traffic for all WMM clients. WMM clients will also classify and prioritize the uplink traffic.
