+ | In this video, a switch loop is created because the top and bottom switches are connected to the router as well as to each other. Removing either redundant ethernet cable and connection will solve the issue. At the beginning of the video, notice how all the switch lights are on and blinking rapidly. The redundant cable is unplugged and the lights and network traffic returns to normal. | ||

+ | This might be simple, just examining most network cables for cross connects may show you 2 or three cables between switches. In the video above, there is a 3rd switch off camera that both bottom switches are plugged into, as well as a cross connect. | ||
