This read-create INTEGER (0..63) specifies the new DSCP value that a QoS remarking policy applies to a packet's IP header when that packet is classified as exceeding its committed rate. An admin uses it to configure how out-of-profile traffic gets downgraded in priority via remarking rather than being dropped outright. For example, setting this to 0 would remark exceeding traffic to best-effort DSCP, while a value like 10 (AF11) would demote it to a lower-priority class instead of the default marking.
