Initial Configuration for Data Collection

After successfully installing NFO (following the Installation Guide), the next crucial step is to configure NFO to receive flow data:

  • Accessing the NFO Web Interface: Open a web browser and navigate to https://<NFO_server_IP_or_hostname>:8443. Log in using the initial credentials (as described in the Getting Started Guide). You will likely be prompted to change these credentials.
  • Configuring NetFlow Listeners: Navigate to the "Inputs" (refer to the Administration Guide for the exact location).
    • Verify the default NetFlow listener on UDP port 9995.
    • If necessary, add additional listeners for different ports or interfaces based on your network setup.
  • Configuring Flow Exporters: On each network device that will send flow data:
    • Enable flow export functionality.
    • Set the destination IP address to the IP address of your NFO server.
    • Set the destination UDP port to the configured NFO listener port (typically 9995).
    • Specify the source interfaces or the scope of traffic to be exported.
    • Choose the desired flow protocol, if applicable (e.g., NetFlow v9, IPFIX, sFlow).
    • Refer to your specific network device vendor's documentation for detailed configuration steps.
