In this post, we will guide you through the process of configuring Rapid Spanning Tree Protocol (RSTP) on your Nebula switches. RSTP is a network protocol that helps prevent loops in Ethernet networks, ensuring efficient and reliable data transmission. By implementing RSTP, you can enhance network stability and improve network performance. We will provide step-by-step instructions to help you enable RSTP and modify STP bridge priority using the Nebula Control Center.



  • Access the Nebula Control Center.
  • Once logged in, navigate to the Site-wide > Configure > Switches > Switch settings
  • Within the Switch settings, find the STP configuration and enable RSTP.
  • Modify the STP bridge priority for switches that need to join the RSTP network.
    • The lower the bridge priority value, the higher the priority of the switch in the RSTP network.
  • Save the changes and wait for the configuration to be applied to the switches.
  • You should find there is a switch port that must be blocked in a ring topology.
    • Check status via NCC
  • Check status via console/SSH

Verification and Noted:
To ensure that the RSTP configuration has been successfully applied and is functioning as intended, follow these verification steps:

  1. Physically inspect the network to confirm that there are no loops or unexpected network topology changes.
  2. Monitor the network traffic to verify that RSTP is effectively preventing loops and maintaining network stability.
  3. Perform network tests to check for any improvement in network performance and latency.

Note: It is essential to plan and test the RSTP configuration thoroughly before deploying it in a production environment. Additionally, remember to regularly monitor and maintain your network to ensure its continued optimal performance.

By following these simple steps, you can configure RSTP on your Zyxel networking devices and enhance the stability and efficiency of your network.
