The MIB's DESCRIPTION for cucsLicenseInstanceOperState is only the auto-generated stub 'Cisco UCS license:Instance:operState managed object property', but the 'operState' property name together with its CucsLicenseState type tell us this column, on a specific licensed-feature grant on a fabric interconnect (a feature name plus a quantity), holds the operState as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The operState is the current activation state of this license instance using the CucsLicenseState enumeration, which is the field that answers the practical question of whether the feature this instance governs is usable right now. An operState of 'unlicensed' on the port-activation feature means those extra fabric-interconnect ports are physically present but administratively locked until licensed.
