Loop Protection
L2 Loop Protection feature allows loop detection in downstream switches that do not run spanning tree.
It can optionally disable the associated port on loop detection.
The Loop Protection feature is not intended for ports that serve as uplinks between spanning tree aware
switches. Loop Protection feature is designed for unmanaged switches which drop spanning Tree
BPDUs. This feature detects physical and logical loops between Ethernet ports on a device. The feature
needs to be enabled globally before enabling it at the interface level for the system policy filter to be
installed.
Loop Protection Configuration
Use the Loop Protection Configuration page to configure the Loop Protection feature. Loops on a
network consume resources and can impact network performance. When loop protection is enabled on
the switch and on one or more interfaces (ports and trunks), the interfaces send loop protection
protocol data units (PDUs) to the multicast destination address 01:80:C2:00:00:08. When an interface
receives a loop protection PDU, it compares the source MAC address with its own. If the MAC addresses
match, a loop is detected and a configured action is taken, which may include shutting down the port
for a specified period. An interface can also be configured to receive and take action in response to loop
protection PDUs, but not to send out the PDUs itself.
