13.1 Spanning Tree Protocol Overview

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.

13.1.1 What You Can Do

• Use the Spanning Tree Protocol Status screen
different STP modes (RSTP, MRSTP or MSTP) you can configure on the Switch.
• Use the Spanning Tree Configuration screen
modes on the Switch.
• Use the Rapid Spanning Tree Protocol Status screen
• Use the Rapid Spanning Tree Protocol screen
• Use the Multiple Spanning Tree Protocol screen
• Use the Multiple Spanning Tree Protocol Status screen

• Use the Multiple Rapid Spanning Tree Protocol screen
• Use the Multiple Rapid Spanning Tree Protocol Status screen
MRSTP status.

13.1.2 What You Need to Know

Read on for concepts on STP that can help you configure the screens in this chapter.
(Rapid) Spanning Tree Protocol
(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.
The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence of the
