![]() ![]() This, in turn, allows IPFIX analysers much more flexibility around reporting capabilities. This may be information which traditionally has been sent using SNMP, or syslog, or indeed anything else. IPFIX also allows vendor IDs to be specified, permitting the exporting of proprietary information. IPFIX, as well as being an industry standard (rather than proprietary), is much more flexible, allowing the flow data to present additional information (through the use of variable length fields) such as HTTP hostname, or HTTP URL. This standard defines how the IP flow information should be formatted and exported to flow Collectors. IPFIX (Internet Protocol Flow Information Export), is effectively NetFlow v10, which allows for much more granularity of flow information to be generated and reported upon. However, these versions can be somewhat limited for current requirements, which is why businesses should be looking at IPFIX. NetFlow analyzer collects NetFlow and other flow technologies, such as sFlow, jFlow, other flow variants (Xflow) and SNMP for network monitoring and analysis. ![]() NetFlow can therefore be used (amongst other things) for:Ĭommon versions of NetFlow are NetFlow v5, and NetFlow v9. This information is then exported to a Collector (flows and Collectors operate in a many-to-many relationship – the Exporter can send to multiple Collectors, and Collectors can receive from multiple Exporters. CA Network Flow Analysis leverages your existing investments, harnessing data from Cisco IOS® NetFlow- and IP Flow Information Export (IPFIX)-enabled routers and switches. what system is talking to what system(s), when, for how long, and how often (other metrics can also potentially be gathered). ![]() NetFlow is generated from Layers 3 and 4 of the IP stack, and is best described as being data specific to the communications flow, i.e. ![]()
