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 it ensures that only one path at a time is active between any two nodes on the network.
Spanning-Tree Protocol can be enabled using web management’s switch setting advanced item, and selecting enable Spanning-Tree protocol. By default, spanning tree is disabled on the switch.
It is recommended that STP be enabled on all switches to ensure a single active path on the network.
