6-11 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.
Web Interface
To configure the DSCP Mapping in the web interface:
1. Click Quality of Service and DSCP Mapping.
2. Select Queue ID.
3. Click the Apply to save the setting.
4. If you want to cancel the setting then you need to click the Reset button. It will revert
to previously saved values.
