Rapid Spanning Tree Protocol (RSTP)
Rapid spanning tree protocol (RSTP) is supported on the MXL switch platform.
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 operating system (OS) supports three other variations of spanning tree, as shown in the
following table.

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