The value of tmnxCflowdAggregation is a bit mask which specifies the
aggregation scheme(s) currently used to aggregate multiple individual
flows into an aggregated flow for export to one or more remote host
collectors configured in the tmnxCFHostTable.
If no aggregation scheme is specified, {}, no data will be exported.
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 the remote host
collector.
