This value classifies the type of the record-definition object that specifies which packet fields a NetFlow monitor treats as flow keys and which extra fields it exports alongside them — for instance whether it is oriented toward LAN/Ethernet traffic or SAN/Fibre Channel traffic. An administrator relies on this type classification to know which downstream tooling (LAN analytics versus SAN analytics) should be consuming the data this particular NetflowRecordDef instance produces. For example, filtering an inventory of NetflowRecordDef objects by this type field lets an operator quickly separate the Ethernet-side monitors or endpoints from the Fibre-Channel-side ones.
