Spanning Tree Protocol
13.1 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 ( Section 13.2 on page 106 ) to view the STP
status in the different STP modes (RSTP, MRSTP or MSTP) you can configure on the Switch.
• Use the Spanning Tree Configuration screen ( Section 13.3 on page 107 ) to activate one of the
STP modes on the Switch.
• Use the Rapid Spanning Tree Protocol screen ( Section 13.4 on page 108 ) to configure RSTP
settings.
• Use the Rapid Spanning Tree Protocol Status screen ( Section 13.5 on page 109 ) to display
the status screen as shown next.
• Use the Multiple Rapid Spanning Tree Protocol screen ( Section 13.6 on page 111 ) to
configure MRSTP.
• Use the Multiple Rapid Spanning Tree Protocol Status screen ( Section 13.7 on page 112 ) to
view the MRSTP status.
• Use the Multiple Spanning Tree Protocol screen ( Section 13.8 on page 114 ) to configure
MSTP.
• Use the MSTP Port Configuration screen ( Section 13.8.1 on page 117 ) to configure MSTP
ports.
• Use the Multiple Spanning Tree Protocol Status screen ( Section 13.9 on page 117 ) to view
the MSTP 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.
