3.2 Spanning Tree Protocol
Spanning Tree Protocol (STP) is a link management protocol that provides path
redundancy while preventing undesirable loops in the network. For an Ethernet network to
function properly, only one active path can exist between two stations. The UMG-2000
Series uses STP on the switch (Port 1 to Port 26) to detect the loop link. If the loop occurs,
the information will be presented in the “Overview” page. Then, unplug the indicated cable
and check your physical Ethernet link.
