DSCP to Queue
The DSCP to Queue mapping 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 changing the DSCP to Queue mapping, the Queue schedule method, and
bandwidth allocation, it is possible to achieve improved quality of service in a
network.
The DSCP to Queue mapping is applicable to IP packets when:
• The switch is in Basic mode and DSCP is the trusted mode
• The switch is in Advanced mode and the packets belongs to flows that are
DSCP trusted
Non-IP packets are always classified to the best-effort queue.
