cmAccPortPcpDEDecOutPriority is a read-write value giving the priority recovered after decoding an incoming PCP value on this access port. An administrator uses this to define what priority a frame should be re-marked with internally once its incoming PCP-encoded drop-eligibility information has been interpreted. For example, a frame arriving with an encoded PCP value representing drop-eligible priority 4 would, via this object, be assigned an internal priority of 4 for further QoS treatment on the access port.
