Enable IPFIX export on a Juniper router

Configure sampling and an IPFIX flow-server export on Junos.

What you'll need

  • Admin access to the device's CLI (console, SSH or Telnet)
  • The router already added in Zynty
  • The collector's IP address
1

Define a sampling instance

Junos sends flow data through a sampling instance rather than a per-interface flag. Point it at your collector's IPFIX listener.

configure
set forwarding-options sampling instance zynty-ipfix family inet output flow-server 10.20.0.50 port 4739
set forwarding-options sampling instance zynty-ipfix family inet output flow-server 10.20.0.50 version-ipfix template-refresh-rate packets 100
set forwarding-options sampling instance zynty-ipfix family inet input rate 100

Attach sampling to interfaces

Enable sampling on each interface you want flow visibility on.

set interfaces ge-0/0/1 unit 0 family inet sampling input
set interfaces ge-0/0/2 unit 0 family inet sampling input

Confirm on the device side

Junos exposes sampling and export statistics you can check before relying on the Zynty dashboard.

Verify in Zynty

Once records start arriving, the device's Protocols tab shows IPFIX as active with a live records-per-minute count.
