L2 Features > Loopback Detection
The Loopback Detection function is used to detect loops 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 looping
port will be unlocked when the Loopback Detection Recover Time times out. Loopback Detection can also
be enabled or disabled for a specified range of ports simultaneously.
The fields that can be configured are described below:
