Rapid Spanning Tree Protocol (RSTP)

Rapid spanning tree protocol (RSTP) is supported on Dell Networking OS.

Protocol Overview

RSTP is a Layer 2 protocol — specified by IEEE 802.1w — that is essentially the same as spanning-tree protocol (STP) but provides
faster convergence and interoperability with switches configured with STP and multiple spanning tree protocol (MSTP).
The Dell Networking OS supports three other variations of spanning tree, as shown in the following table.

Multiple Spanning Tree Protocol (MSTP)
Per-VLAN Spanning Tree Plus (PVST+)

Configuring Rapid Spanning Tree

Configuring RSTP is a two-step process.
1. Configure interfaces for Layer 2.
2. Enable the rapid spanning tree protocol.

Related Configuration Tasks

• Adding and Removing Interfaces
• Modifying Global Parameters
• Modifying Interface Parameters
• Configuring an EdgePort
• Prevent Network Disruptions with BPDU Guard
• Influencing RSTP Root Selection
• Configuring Spanning Trees as Hitless
• Enabling SNMP Traps for Root Elections and Topology Changes
• Configuring Fast Hellos for Link State Detection
• Flush MAC Addresses after a Topology Change

Important Points to Remember

• RSTP is disabled by default.
• Dell Networking OS supports only one Rapid Spanning Tree (RST) instance.
• All interfaces in virtual local area networks (VLANs) and all enabled interfaces in Layer 2 mode are automatically added to the
RST topology.
