Packet Capture

3.9.5

NF can capture BACnet network packets in real time and stream them as PCAP files for analysis in Wireshark or similar tools.

Starting a Capture

From the BACnet settings page, start a capture session by specifying:

  • Network interface
  • Protocol (TCP/UDP) and port range
  • Duration (maximum 1 hour)

The system generates a time-limited download URL. Packets are captured with BPF filters and streamed via HTTP with periodic flushing, so you can open the file in Wireshark while the capture is still running.

Use Cases

  • Debugging device communication problems
  • Verifying BACnet traffic on the network
  • Diagnosing timeout or concurrency issues
