This enumerated value states whether this collector is reached over the fabric interconnect's internal (in-band, fabric-side) network or an external (out-of-band management) path. It determines which physical interface actually carries the exported flow packets, which matters if flow export appears to work internally in lab testing but never reaches a collector sitting off the management network, or vice versa. A value of 'external' would mean flow records for this collector go out the fabric interconnect's management interface rather than a fabric uplink.
