This object specifies the forwarding class, such as best-effort or expedited forwarding, that a DSCP remarking table entry maps traffic to, chosen from a fixed set of named priority classes like be, af, and ef. An administrator sets this to control which QoS treatment class matching traffic gets remarked into as it passes through the device. For example, setting this object to ef(6) on an entry remarks the matched traffic into the expedited-forwarding class, giving it low-latency handling.
