NOTE:
The PoE Switch default had enabled the STP (Spanning Tree Protocol) , if you want
to enable the Loop Protection in the same PoE Switch, you must disable the STP
function first. (Click Switch > Configuration > Spanning Tree, CIST Port to disable
STP in each port). The STP can also disable network loops, and STP has a higher
priority than the Loop Protection feature.
