DSCP to 802.1p Mapping
Use the DSCP to 802.1p page to assign Class of Service (CoS) values to the priority
queues (i.e., hardware output queues 0 - 3) on the CPE.
Most CPEs currently support Class of Service by using four priority queues, with
Weighted Round Robin queuing for each port. Eight separate traffic classes are
defined in IEEE 802.1p. The default priority levels are assigned as shown below.
