This OID carries the Relative Name (RN) of an OperLevel object, the record of the VLAN and VIF scalability ceilings a Fabric Interconnect currently operates under for its switching mode — the naming component that distinguishes this instance from its siblings under the same parent object. Because OperLevel instances are addressed by concatenating RNs down the management tree, an admin uses this value together with the parent DN to reconstruct exactly where this instance sits. For example, two OperLevel instances that share the same parent will report different cucsNetworkOperLevelRn strings, letting a script tell them apart even when their other property values look identical.
