5.35 Single Port Loop Detection Configuration

Single Port Loop Detection Overview
Single port loop detection is to check whether a loop exists in the ports of the switch. If such
a loop exists, it may result in errors in learning MAC addresses and may easily cause a
broadcast storm. In severe case, switch and network may be down. Starting the single port
loop detection and disabling the port with loop can efficiently avoid the influence caused
by port loop.
The switch sends a test packet through a port. If this test packet is received through the
port without any change (or only a tag is attached), it indicates that a loop exists in this
port.
The test packet sent by the switch includes the following three parameters:
l
Source MAC address: It indicates the MAC address of the switch. The MAC address
of each switch is unique.
