3.17 Loop Protection
Loop detection detects the presence of traffic. When a switch becomes aware that a packet’s (looping detection frame) MAC address is the same that of its own port, Loop Protection activates. The port will be locked when it receives the looping detection frames. To resume the locked port, locate and remove the looping path, select the locked port and click on “Resume“.
