Configuring Full NetFlow Export in IPFIX Format
The netflow_full_collector_type parameter defines the export format for full NetFlow. Possible values:
0- export in NetFlow5 format (default value).1- export IPFIX to a UDP collector.2- export IPFIX to a TCP collector.
The netflow_tos_format parameter defines the format of the TOS field data in IPFIX. Possible values:
0- 3 bits are transmitted (default value).1- 6 bits are transmitted (full DSCP).
The netflow_plc_stat parameter defines the set of transmitted statistics data for dropped packets according to policing or drop rules. The parameter is a bitmask.
By default, the mask has the value 0x07 — statistics for dropped data of session + subscriber + virtual channel policing are transmitted.
Affects the formation of the DROPPED_BYTES and DROPPED_PACKETS counters.
Values that make up the mask:
0xff- any drop is transmitted0- do not count1- count for session policing2- count for subscriber policing4- count for virtual channel policing8- count when packets are dropped (drop) by protocol16- count in all other cases
The ipfix_mtu_limit parameter sets the maximum UDP packet size when sending IPFIX. By default, it equals the minimum MTU of the interfaces used for sending.
The configuration parameter
ipfix_reserved allows reserving the necessary memory to enable/change IPFIX/Netflow parameters.If IPFIX/Netflow parameters are set in the configuration file, memory reservation for IPFIX/Netflow is automatically enabled, and IPFIX/Netflow parameters and new exporter types can be changed without restarting fastDPI.
For collecting information in IPFIX format, any universal IPFIX collector that understands templates, or the IPFIX Receiver utility, is suitable.
