Legacy Open Mesh: Switches: Spanning Tree Protocol



This article describes Spanning Tree Protocol and how to implement it on an Open Mesh Switch.


  • Open Mesh Switches


Spanning Tree Protocol is a Layer 2 protocol that prevents loops in networks with redundant paths created by multiple switches. Open Mesh Switches support three variations of this protocol, which are explained below.


1. Navigate to ManageSwitches and select a switch.

2. Click Switch Settings.

4. Click the drop-down menu 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 with 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.
