Multiple Macs and Network Flooding?
The Technology Firm
I always get requests to demonstrate everyday things that I do that may help you out. If you ‘use’ your various tools, you are bound to develop skills and technique that can not be taught in a classroom or in YouTube video. In this example, I noticed the network was a bit ‘laggy’ and simply started a Wireshark capture and a conversation between my NVR and my camera filled my screen. This is ver odd when you realize that I did not have span port or tap in use. When I took a closer look at the [packets, I noticed that the delta time was less than 1 ms, which would mathematically result in 1000 packets per second. Since all the packets were unique, I knew this was NOT a loop of any kind, but why was this conversation getting flooded across my network. In the video you see that I verified that the mac address the NVR was using was the camera’s wifi mac but oddly enough the camera was still responding to the NVR using the wifi mac even though it was clearly using the wired connection. I show you the odd Wireshark trick, so enjoy and don’t be afraid to capture a few packets. Fyi. went dyslexic with the mac address at one point. I’m sure you will out where. ... https://www.youtube.com/watch?v=EMUVBoA-Lqg
