4.7.2 Loop Protection
Loops sometimes occur in a network due to improper connecting, hardware problem or faulty protocol settings. When
loops are seen in a switched network, they consume switch resources and thus downgrade switch performance. Loop
Protection feature is provided in this switch and can be enabled globally or on a per port basis. Using loop protection
enables the switch to automatically detect loops on a network. Once loops are detected, ports received the loop
protection packet form the switch can be shut down or loopped events can be logged.
