This definition of flows is also used for IPv6, and a similar definition is used for MPLS and Ethernet flows. Advanced NetFlow or IPFIX implementations like Cisco Flexible NetFlow allow...
There are technically ten different versions of NetFlow. However, several versions were released only internally or were never widely implemented beyond specific hardware. The original NetFlow version 1 is considered obsolete, and seldom used today. Versions 2 through 4 were internal versions, no public implementation was ever released. Version 5 is still commonly used today, because of a large existing install base of Cisco routers and switches released while it was the standard version. It added Border Gateway Protocol information and flow se ...
Netflow plugin for Fluentd ; Use RubyGems: bind · IP address on which the plugin will accept Netflow. (Default: '0.0.0.0') · port · UDP port number on which tpe plugin will accept Netflow. (Default: 5140) · cache_ttl · Template cache TTL for Netflow v9 in seconds. Templates not refreshed from the Netflow v9 exporter within the TTL are expired at the plugin.

Last updated: May 2011 ; Third-party business partners who produce applications that provide collector or display services for NetFlow will not be required to recompile their applications each time a new NetFlow feature is added; instead, they may be able to use an external data file that documents the known template formats · New features can be added to NetFlow more quickly, without breaking current implementations · NetFlow is "future-proofed" against new or developing protocols, because the Version 9 format can be adapted to provide suppo ...
