This read-create integer (0-63) is another "new DSCP" remark value, applied within the remark-map (Rm) portion of the QoS configuration rather than the general class-based remarking. It matters because it lets an admin override the DSCP a packet carries as part of a distinct remark-mapping table, independent of the primary classification rules. For example, an operator building a DSCP-to-DSCP remark map could set this field to 0 to reset traffic from an untrusted DSCP value down to best-effort.
