3.8 Loop Detect/Prevent
GS-5008PL provides a Loop Protection feature for unmanaged environments. Two kinds of mechanism
are available in the GS-5008PL, which are Loop Detection and Loop Prevention. Users can choose to
enable Loop Detection or Loop Prevention.
The Loop Discovery frame uses the system mac as source address. When the port receives the discovery
frame and the source mac is the same as system mac, this will be determined as a loop.
When the Loop Detection feature is enabled and activated, the switch generates Broadcom proprietary
tag frames (Loop Discovery Frames) at a programmed interval, and when it detects a loop, it gives a loop
detected warning with a down port LED, and the system LED will be blinking. This feature does not repair
the loop, but only issues a warning.
The GS-5008PL also includes a Loop Prevention feature which can be enabled. When Loop Prevention is
enabled and loop is detected, this feature will disable loop ports and down port LED, and the system LED
will be blinking.
