2.2.5 Loopback Detection
When Spanning Tree Protocol (STP) is not enabled in the network, the Loopback
Detection function can be used to detect the loop created by a specific port. Click the
Loopback Detection link under the L2 Feature menu to configure loop detection for
loops created by a specified port. For users connecting hubs or unmanaged switches,
the Loopback Detection function shuts a port when packets are sent and received
from the same port--a loopback effect. The port is automatically unlocked after the
recovery period times out.
