4.3.7 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.
General Settings
Enable Loop Protection:
Enable or disable loop protection function.
Transmission Time:
The interval between each loop protection PDU sent on each port. Valid values are 1 to 10
seconds.
Shutdown Time:
The period for which a port will be kept disabled. Valid values are 0 to 604800 seconds. 0 means that
a port is kept disabled until next device restart.
Port Configuration
Port:
List the number of each port. “Port *” settings apply to all ports.
