5-4-8. Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D ) for avoiding loops in switched networks. When STP is enabled, this method ensures that only one path at a time is active between any two nodes on the network.

You can enable Spanning-Tree Protocol in the Web Management’s advanced page. Select enable Spanning-Tree protocol. We recommend you enable STP on all switches to ensure a single active path on the network.
