Page 113: Configuring Spanning Tree
DGS-3100 Series Gigabit Stackable Managed Switch User Manual Configuring Spanning Tree Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges, as well as providing a single path between end stations on a network, thus eliminating loops.
