Table 22 Service classes
The service class is equivalent to the 802.1D UP (user priority) with the exception
that its scale is linear:
Table 23 Relationship between service class and 802.1D UP.
6.13.2 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 user is allowed
to 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
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.
6.14 Working with Quality of Service (QoS)
QoS policy is configured for each VNS and applies to routed, bridged at AP, and
bridged at controller VNSs.
