Verifying the NetFlow export port

Verifying the NetFlow port of an On-Premise Poller

For NetFlow analysis, you need to configure your devices to export flows to Site24x7 On-Premise Poller, which is the NetFlow collector. The On-Premise Poller will be listening to the particular port to receive flows, which is why a proper port number should be configured for every flow export. Port numbers may vary with On-Premise Pollers, so it's important to mention the correct port number used by the associated On-Premise Poller.

The default port for NetFlow export is 9996. However, when an On-Premise Poller initializes, if it finds that the port is already occupied by another service, then the On-Premise Poller will use an alternative port, like 9997 or 9998.

You can view the port number by navigating to Admin > Inventory > Add Monitor > Flow Export (under NetFlow) > On-Premise Poller. 

The NetFlow port corresponding to your On-Premise Poller is listed here. Copy this port number, and use for flow export configuration.
