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.
The DSCP to Queue mapping is applicable to IP packets if:
The device is in QoS Basic mode and DSCP is the trusted mode, or
The device is in QoS Advanced mode and the packets belongs to flows that is DSCP
trusted
Non-IP packets are always classified to the best-effort queue.
