The value of tmnxCFHostAggregation is a bit mask which specifies the
aggregation scheme(s) used to aggregate multiple individual flows
into an aggregated flow for export to this remote host collector.
If no aggregation scheme is specified, {}, no data will be exported
for this remote collector host. If the 'raw (5)' scheme is specified,
flow data is exported without aggregation in version 5 format.
All other aggregation types use version 8 format to export the flow
data to this remote host collector.
