Enable Loop Prevention

If loop prevention is enabled and the switch detects a loop, the switch blocks one of the ports that are part
of the loop and both LEDs of that port blink at a constant speed. If two ports are part of a loop, the port with
the highest port number is blocked. For example, if port 1 and port 2 are part of a loop, port 2 is blocked
while port 1 continues to process traffic. The loop status (that is, port blocking and LED blinking) is cleared
if the switch does not detect the loop for a period of about four seconds.
To enable loop prevention:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired network connection, or connect directly to a switch that is off-network using
an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
