flow-server

Syntax

Hierarchy Level

Description

Collect an aggregate of sampled flows and send the aggregate to a specified host system that runs the collection utility cfdcollect. Specify a host system to collect sampled flows using the version 9 format.

You can configure up to one version 5 and one version 8 flow format at the [edit forwarding-options sampling family (inet | inet6 | mpls) output flow-server hostname] hierarchy level. For the same configuration, you can specify only either version 9 flow record formats or formats using versions 5 and 8, not both types of formats.

Options

hostname—IP address–IPv4 or IPv6–or identifier of the host system (the workstation either running the cflowd utility or collecting traffic flows using version 9).

Note:

Only host systems running IPv4 are supported on QFX10000 switches.

You can configure only one host system for version 9.

Note:

IPv6 coniguration for flow-server is supported only in Junos OS Release 12.3 and later.

Note that when you configure an IPv6 address for the flow-server statement, you must also configure an IPv6 address for the inline-jflow source-address statement at the [edit forwarding-options sampling instance instance-name family (inet | inet6 | mpls | vpls | bridge) output] hierarchy level.

The remaining statements are explained separately. See CLI Explorer.
