cmNetPortPcpDEEncInPriority is a read-write value on a network port specifying the input priority that gets translated into a PCP value carrying an implicit drop-eligible or drop-ineligible indication. An administrator configures this per encoding-table row to define which priority level triggers a given PCP encoding rule as traffic leaves toward the network. For example, a network port encoding priority 6 traffic distinctly from priority 2 traffic would use two separate rows of this object, one set to 6 and another to 2.
