Mapping DSCP Values to Queues

The DSCP to Queue page provides fields for defining output queue to specific DSCP fields. For the list of the DSCP default queue settings, see "DSCP to Queue Mapping Table Default Values" on page 145. To open the DSCP to Queue page, click Quality of Service→ CoS Global Parameters→ DSCP to Queue in the tree view.

•DSCP In — The values of the DSCP field within the incoming packet.

•Queue — The queue to which packets with the specific DSCP value is assigned. The values are 1–4, where one is the lowest value and four is the highest.
