Chapter 8 Raw Data Formatting: The RDR Formatter and NetFlow Exporting

NetFlow Exporting Support

The RDR formatter supports the exporting of NetFlowV9 reports and is able to send export packets to
the configured destinations. The packets contain template records and data records. The template records
define the format of the following data records. Each export packet may contain both types of records,
or only one type of records.
NetFlow Templates
Each RDR type supported for NetFlowV9 exporting has a pre-defined mapping that allows the RDR
formatter to convert it to a NetFlow V9 report and sent it over a NetFlow destination. The SCE platform
maintains template records for several RDR types, with the structure of each NetFlow data record that
corresponds to that RDR type. All NetFlow templates are pre-defined; users cannot create or edit the
NetFlow templates.
If an RDR tag that is not supported for NetFlow exporting is configured to be sent over a NetFlow
Note
destination, this report will not be formatted and sent, and a special counter will be incremented along
and a warning will be logged. (See the output of the show rdr-formatter statistics command –
'unsupported-tags'.)
Although template records and data records can be mixed in the same export packet, the template must
precede any related data records. For this reason, templates are included in the first export packet, the
first time a record is sent, and again at configured intervals (template refresh) to ensure that data records
will be recognized and read correctly.

Data Destinations

The SCE platform can be configured with a maximum of eight destinations, three destinations per
category. Each destination is defined by the following parameters:

The destination is assigned a priority for each category to which it is assigned.
The following figure illustrates the simplest data destination topology, with only one category and one
destination.
