This read-write PcpDEPairsAction object lets an admin manage Priority Code Point (PCP) Drop Eligibility Pairs on a port when cmEthernetNetPortExpDEEncType uses a paired encoding scheme (7p1d, 6p2d, or 5p3d); the associated cmNetPortExpDEPairTable specifies alternate priority pairs for drop eligibility/ineligibility. Admins use this action object to trigger or manage updates to those pair mappings, which is necessary because a paired PCP encoding scheme means one nominal priority value can represent either a drop-eligible or drop-ineligible variant. For example, when moving from a 5p3d encoding scheme to 7p1d, an admin would use cmEthernetNetPortExpDEPairsAction together with the pair table to redefine which PCP priority pairs represent eligible-vs-ineligible traffic under the new scheme.
