This read-write PcpDEPairsAction object lets an admin manage PCP Drop Eligibility Pairs specifically within an encapsulation header's tag, used when cmEthernetNetPortEncapPcpDEEncodingType is set to a paired scheme (7p1d, 6p2d, or 5p3d), with the associated cmNetPortEncapPcpDEPairTable holding the alternate priority pairs. Admins use this the same way as the non-encapsulated pairs-action object, but scoped to the encapsulation header context, which matters because tunneled/pseudowire services carry their own independent PCP DE pairing. For example, when the encapsulation header's PCP encoding moves to a 6p2d scheme, an admin would use cmEthernetNetPortEncapPcpDEPairsAction to redefine the drop-eligible/ineligible priority pairings for that encapsulated tag specifically.
