Mapping DSCP to Queue
The DSCP (IP Differentiated Services Code Point) to Queue page maps DSCP values to egress queues. The
DSCP to Queue Table determines the egress queues of the incoming IP packets based on their DSCP
values. The original VPT (VLAN Priority Tag) of the packet is unchanged.
By simply changing the DSCP to Queue mapping and the Queue schedule method and bandwidth
allocation, it is possible to achieve the desired quality of services in a network.
DSCP to Queue mapping is applicable to IP packets if DSCP is the trusted mode.
Non-IP packets are always classified to the best-effort queue.
