This OID reports the Relative Name of an NFExporterRef instance, the naming property that distinguishes it from sibling NFExporterRef objects sharing the same parent container. Admins rarely read the Rn on its own, but SNMP tools and UCS Manager use it together with the parent's DN to reconstruct which specific exporter reference a given row belongs to, and to tell apart multiple similarly configured instances. If a fabric interconnect hosts several NFExporterRef objects side by side, each reports a different Rn even when most of their other properties are identical.
