and/or 802.11e clients in that VNS are instructed by the AP to transmit all
traffic classified to VO AC with special contention parameters tailored to
maximize voice performance and capacity.
Note: The HiPath Wireless 802.11n supports only the WMM QoS mode.
5. To define the service class and DSCP marking for the VNS, select the
Priority Override checkbox. For each DSCP you can click one of the eight
service classes.
• Service class – From the drop-down list, click the appropriate priority
level:
• Network control (7) – The highest priority level.
• Premium (Voice) (6)
• Platinum (5)
• Gold (4)
• Silver (3)
• Bronze (2)
• Best Effort (1)
• Background (0) – The lowest priority level
• DSCP marking – From the drop-down list, click the DSCP value used to
tag the IP header of the encapsulated packets.
Note: The HiPath Wireless 802.11n does not support the Priority Override
feature.
6. If you want to assign a service class to each DSCP marking, clear the Priority
Override checkbox and define the DSCP service class priorities in the DSCP
classification table.
When Priority Override is enabled, the configured service class overrides
queue selection in the downlink direction, the 802.1P user priority for the
VLAN tagged Ethernet packets and the user priority for the wireless QoS
packets (WMM or 802.11e), according to the mapping between service class
and user priority. If Priority Override is enabled and the VNS 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.
7. The Advanced Wireless QoS options are only displayed if the WMM or
802.11e checkboxes are selected:
