Edit RSTP

Table of contents of this topic

Rapid Spanning Tree Protocol (RSTP) uses point-to-point wiring and provides rapid convergence of the spanning tree.

If there are more than one point-to-point connections between two switches, RSTP manages the redundant link unless the original connection fails.

Important:
The MA Network Switch support an implementation of RSTP that is compatible with the IEEE 802.1w standard and does not support per VLAN RSTP. This means that the MA Network Switch will send out and expect to receive untagged RSTP messages.
Figure 1: Edit RSTP

By default, RSTP is enabled.

  • Disabled = Red dot
    The switch does not run RSTP for this port. If RSTP is disabled, LLDP (Link Layer Discovery Protocol) is disabled as well.
  • Enabled = Green dot
    The switch runs RSTP for this port. If RSTP is enabled, LLDP (Link Layer Discovery Protocol) is enabled as well.

Requirement: Connection to the web interface.

  1. Click Edit Ports / Groups.
  2. Click in the RSTP box for that port you want to enable or disable.
  3. Click Apply settings and stay where you are or Apply settings and leave edit.

RSTP is enabled or disabled for the selected port and saved in the startup configuration.

Example

Let´s assume, you have two connected MA Network Switches with two Trunk ports by accident.
If you have more than one connection between two devices, RSTP is necessary.
If RSTP is would be disabled in that example, there is no connection.
