cmAccPortPcpDEEncInPriority is a read-write value on an access port that specifies the input priority which gets translated into a PCP value carrying an implicit drop-eligible or drop-ineligible indication. An administrator configures this as the trigger priority in the priority-to-PCP encoding scheme used to signal per-frame drop eligibility toward the network side. For example, an access port marking a customer's priority-3 traffic as drop-eligible would use this object to designate priority 3 as the input value driving that PCP encoding rule.
