Iii-10 Loop Detect/Prevent - Edimax GS-5008E Manual

III-10 Loop Detect/Prevent

GS-5008E provides a Loop Protection feature for unmanaged environments.
There are two kinds of mechanism are available, 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 found that the source MAC is the same
as system MAC, loop is determined.
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 indication, and the system LED will be blinking.
This feature does not repair the loop, but only issues a warning.
When Loop Prevention is enabled and loop is detected, this feature will
disable loop ports and dim the port LED, and the system LED will be blinking.
On the Loop Detect/Prevent page, select either "Off", "Loop Detection" or
"Loop Prevention" and click "Apply" to apply the settings.
