L2 Features > Loopback Detection
The Loopback Detection function is used to detect the loop created by a specific port while Spanning Tree
Protocol (STP) is not enabled in the network, especially when the down links are hubs or unmanaged
switches. The Switch will automatically shut down the port and send a log to the administrator. The Loopback
Detection port will be unlocked when the Loopback Detection Recover Time times out. The Loopback
Detection function can be implemented on a range of ports at a time. You may enable or disable this function
using the pull-down menu.
