Configuration: Spanning Tree

25.1 Overview

This section provides information for Spanning Tree in Configuration.

The Switch supports Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and

Multiple Spanning Tree Protocol (MSTP) as defined in the following standards.

• IEEE 802.1D Spanning Tree Protocol

• IEEE 802.1w Rapid Spanning Tree Protocol

• IEEE 802.1s Multiple Spanning Tree Protocol

The Switch also allows you to set up multiple STP configurations (or trees). Ports can then be

assigned to the trees.

25.2 Spanning Tree

(R)STP detects and breaks network loops and provides backup links between switches, bridges or

routers. It allows a Switch to interact with other (R)STP-compliant switches in your network to

ensure that only one path exists between any two stations on the network.
