This value reports the transport type (such as an Ethernet/IP path) that the record-definition object that specifies which packet fields a NetFlow monitor treats as flow keys and which extra fields it exports alongside them uses to move its traffic or exported data. An administrator troubleshooting a NetflowRecordDef that appears to be silently dropping data checks transport first, since a mismatched or unsupported transport setting is a common reason exported flow data or link traffic never shows up where expected. For example, seeing an unexpected transport value on this NetflowRecordDef would tell an operator to re-check the exporter or link configuration rather than assume the hardware itself has failed.
