4.2. Configuring NetFlow, cFlow, jFlow, IPFIX, and NSEL

Because these protocols are push protocols, you must configure the flow source device to send flow updates to FlowTraq. See Appendix A, Enabling Flow Export on Common Devices for quick-start guides for enabling flow export on common devices, or consult your network device's documentation for more information.

FlowTraq listens for NetFlow, cFlow, jFlow, IPFIX, and NSEL updates on UDP ports 2055, 9666, and 9996. In general, we recommend you use the default ports, but you may change them or configure additional listen ports.

[Tip] Configuring Additional NetFlow, cFlow, jFlow, IPFIX, and NSEL Listen Ports

To configure configure additional NetFlow listen ports, take the following steps.

  1. Log in to FlowTraq as an administrative user.

  2. Click the Preferences button on the Dashboard window's toolbar, or select Edit > Preferences from the menu.

  3. Select the Exporters tab.

  4. Add listen ports to the space-separated list and click "OK" to cause FlowTraq to start listening for NetFlow, cFlow, jFlow, IPFIX, and NSEL on those ports.

    [Tip]Tip

    Each exporter will display either a green light or an "alert" triangle. The green light indicates that flows are being received, while the alert triangle is displayed when FlowTraq has not received any updates from the exporter in a while, or if FlowTraq is having a problem interpreting the updates from that exporter. Move your mouse cursor over the triangle to see the cause of the alert.
