10. Spanning Tree Protocol STP Caution 6 30 Spanning Tree Protocol STP The switch uses the IEEE 802 1d Spanning Tree Protocol STP when enabled to ensure that only one path at a time is active between any two nodes on the network In networks where there is more than one physical path between any two nodes STP ensures a single active path between them by blocking all redundant paths Enabling STP is necessary in such networks because having more than one path between a pair of nodes causes loops in the network which can result in a switch detecting the same node on more than one port This results in duplication of messages leading to a broadcast storm that can bring down the network Enabling STP also allows you to intentionally create redundant links in your network for critical communication paths While allowing only one active path through a network at any time STP retains any redundant physical path to serve as a backup blocked path in case the existing active path fails From the web browser interface you can activate the IEEE 802 1d Spanning Tree Protocol STP from the switch console you can activate STP and adjust spanning tree parameters In the factory default configuration STP is off If there are any redundant paths loops between nodes in your network you should set the Spanning Tree Enabled parameter to Yes Because the switch automatically gives faster links a higher priority STP selects the highe
