Datto Switches: Spanning Tree Protocols

Follow

Topic

This article describes Spanning Tree Protocols and how to implement them on a Datto Switch.

Environment

  • Datto Switches

Overview

A Spanning Tree Protocol is a layer 2 protocol that prevents loops in a network that has redundant paths created by multiple switches. It is recommended to utilize this feature if your environment incorporates multiple switches. Datto Switches supports three variations of this protocol.

Procedure

1. Navigate to a device web session for your switch.

2. Click on Switch Settings.

4. Click the dropdown next to Protocol and choose one of the following:

  • Spanning Tree Protocol: This is the standard Spanning Tree Protocol. A root switch with the lowest bridge switch ID (the bridge priority + the switch's MAC address) is elected. Ports are then flagged in five different states: blocking, listening, learning, forwarding, and disabled.
  • Rapid Spanning Tree Protocol: A newer variation of STP that has three states instead of five: discarding, learning, and forwarding.
  • Multiple Spanning Tree: An expansion of RSTP that supports VLAN implementations.

5. Click Save Switch Settings.
