NetFlow TABLE

A NetFlow target. NetFlow is a protocol that exports a number of
       details about terminating IP flows, such as the principals
       involved and duration.

Summary: targets set of 1 or more strings engine_id optional integer, in range 0 to 255 engine_type optional integer, in range 0 to 255 active_timeout integer, at least -1 add_id_to_interface boolean Common Columns: external_ids map of string-string pairs

Details: targets: set of 1 or more strings NetFlow targets in the form ip:port. The ip must be specified numerically, not as a DNS name.

engine_id: optional integer, in range 0 to 255 Engine ID to use in NetFlow messages. Defaults to datapath index if not specified.

engine_type: optional integer, in range 0 to 255 Engine type to use in NetFlow messages. Defaults to datapath index if not specified.

active_timeout: integer, at least -1 The interval at which NetFlow records are sent for flows that are still active, in seconds. A value of 0 requests the default timeout (currently 600 seconds); a value of -1 disables active timeouts.

The NetFlow passive timeout, for flows that become inactive, is not configurable. It will vary depending on the Open vSwitch version, the forms and contents of the OpenFlow flow tables, CPU and memory usage, and network activity. A typical passive timeout is about a second.

add_id_to_interface: boolean If this column's value is false, the ingress and egress interface fields of NetFlow flow records are derived from OpenFlow port numbers. When it is true, the 7 most significant bits of these fields will be replaced by the least significant 7 bits of the engine id. This is useful because many NetFlow collectors do not expect multiple switches to be sending messages from the same host, so they do not store the engine information which could be used to disambiguate the traffic.

When this option is enabled, a maximum of 508 ports are supported.

Common Columns:

The overall purpose of these columns is described under Common Columns at the beginning of this document.

external_ids: map of string-string pairs
