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.

Dell Networking Term IEEE Specification
Spanning Tree Protocol (STP) 802.1d
Rapid Spanning Tree Protocol (RSTP) 802.1w

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