This switch is compliant with IEEE802.1D Spanning Tree Protocol (STP). STP ensures that only one path at a time is active between any two
network nodes. There are maybe more than one physical path between any two nodes for redundant paths; STP ensures only one physical path is
active and the others are blocked. STP will prevent an inadvertent loop in a network, which can disable your network due to a "Broadcast storm",
the result of a broadcast message traveling through the loop again and again.
