Main Menu> Advanced> Spanning Tree
This switch is compliant with IEEE802.1D Spanning Tree Protocol (STP).
Figure 4-31: Spanning Tree
STP ensures that only one path at a time is active between any two network nodes. There may be
more than one physical path between any two nodes, forming a loop, either created for redundancy
or by accident. STP ensures only one physical path is active and the others are blocked. If a loop is
created for redundancy, STP will monitor the two paths and activate the stand-by path if the
primary path fails. If a loop was created inadvertently, STP will disable one of the two paths. A
loop in a network can disable your network by causing a “Broadcast storm”, the result of a
broadcast message traveling through the loop again and again.
