7-11 DSCP Mapping
Use the DSCP to Queue page to map IP DSCP to egress queues. The DSCP to Queue table
determines the egress queues of the incoming IP packets based on their DSCP values. The
original VLAN Priority Tag (VPT) of the packet is unchanged.
It is possible to achieve the desired QoS in a network by simply changing the DSCP to Queue
mapping, the queue schedule method, and bandwidth allocation.
