rcQoSPolicyMapRowSta is the RowStatus control used to create, modify, or delete an entry in rcQoSPolicyMapTable, which binds a class map to a DSCP-marking action within a named policy map. Admins use it when building or removing a QoS policy map row that ties a traffic class to its DSCP remarking rule. For example, setting rcQoSPolicyMapRowSta to destroy(6) removes a previously configured class-to-DSCP mapping from the policy map.
