Supported Flow Monitoring and Discard Accounting Standards

On routers equipped with one or more Adaptive Services PICs (both standalone and integrated versions), Monitoring Services PICs, or Dense Port Concentrators (DPCs), Junos OS substantially supports the standards for cflowd version 5 and version 8 formats that are maintained by CAIDA and accessible at http://www.caida.org.

RFC 3954, Cisco Systems NetFlow Services Export Version 9 does not define a standard but provides information about flow monitoring. The IETF classifies it as “Informational.”

Internet draft draft-kumar-ippm-ifa-02.txt, Inband Flow Analyzer does not define standards but provides information about Inband Flow Analyzer (IFA). You use this feature to record flow-specific information from an end station or switches across a network.

On MX Series routers, Junos OS partially supports the following RFCs:

  • RFC 5101, Specification of the IP Flow Information Export (IPFIX) Protocol for the Exchange of IP Traffic Flow Information

  • RFC 5102, Information Model for IP Flow Information Export
