      @scottalanmiller What are the basic troubleshooting to be caried out for the issue to be resolved.How to identify the system without the Wireshark tools.Any other idea without the tools

      The long way? Unplug ports from switches one by one to see which one is causing the issue. This is tedious and highly disruptive.

          If you lack managed switches, this is the way to go. Short of standing in front of the switches and starring at them hoping to visually identify the traffic from the blinking lights.

              Without being able to use networking tools or look into the managed switch logs you probably won't be able to do this in a way that won't disrupt the production environment.

                  Depends on the switch. Start by logging into it.

                            Whether the system can be found out as a Virus affected through the switch log itself?or The system needs to be checked by any antivirus

                              You can find out which device or computer is causing the issues first. Once you get it narrowed down to that you can troubleshoot the device to see what is causing it.

                                Not if the packets are null. Right now you are just trying to find the machine in question.

                                    Yes, that's all you care about right now. Figure out what port is generating the traffic. Then unplug it and start to do diagnostics in a secure space.

                                      Heck If it's really causing issues start upluging switch uplink ports and narrow it down to which switch the device is connected to. Then you can narrow your choices down much more.

                                          Yes it will be, is the traffic storms not causing any issues for the users already?

                                            How else do you plan to track down the problem, though? It seems that your choices are to unplug some cables or to just ignore the problem since no one wants their systems unplugged for a minute. What alternative do you have?
