The JNIOR can create a network capture! This network capture can be loaded in a sniffer application such as Wireshark for protocol analysis. To do this simply follow a few steps.

  1. Create a telnet connection to the unit. DO NOT USE THE DCP AS THIS CREATES A LOT OF EXTRA TRAFFIC THAT WILL FILL UP THE BUFFER.
  2. Execute the netstat -r command. This step is optional. If you are going to conduct a test procedure then you migth want to execute this command so that only the traffic that occurs during your test will be captured.
  3. Conduct your test
  4. Use the telnet connection to execute the netstat -c command. This will create the capture file with the network buffer content.
  5. Use the DCP and the folders tab to pull the resulting network.ngpcap file. It is in the temp directory. It will be removed when the unit reboots!
