Any configuration changes made locally on the switch won't be synchronized with Sophos Central. We recommend making changes from the Sophos Central control panel instead.

RSTP port settings

The RSTP port settings tab shows you the Rapid Spanning Tree Protocol (RSTP) configuration for each port on the switch and information about the root bridge. You can configure the status for each port and settings such as path cost, link type, priority, and BPDU forwarding.

You can see the following settings for each port:

  • Port: The port to which the RSTP settings apply.
  • Priority: The port's priority. The lowest priority is the root bridge.
  • Path cost configuration and operation: The relative cost of sending spanning-tree traffic through the port to adjacent bridges within a spanning-tree region.
  • Designated root bridge: The priority of the root bridge and its MAC address.
  • External root cost: The relative cost of the path to the root bridge.
  • Designated bridge: The priority of the designated bridge and its MAC address. This is the bridge with the lowest path cost to the root bridge.
  • Port role: Shows the port's STP role.
  • Port state: Shows the port's STP state.

You can select additional information to show on the RSTP port settings tab. Click the ellipsis Ellipsis. and select the options you want to show. You can select from the following options:

  • Edge port configuration/operation: Shows whether the port is configured as an edge port and whether it's in operation. Edge ports are usually connected to endpoint computers or servers. When the network topology changes, edge ports can bypass the listening and learning state and change their STP state directly from blocking to forwarding, speeding up spanning tree generation.

  • P2P MAC configuration/operation: Shows the status of the Point-to-Point (P2P) link and whether it's in operation. P2P links are ports connected to other network devices. For faster convergence, if the port of the P2P link is elected as the root port or the designated port, it can change its STP state directly to forwarding, speeding up spanning tree generation. You'll see one of the following settings:

    • Auto: The switch automatically checks if the port is connected to a P2P link and then sets the status.
    • Yes: The port is connected to a P2P link.
    • No: The port isn't connected to a P2P link.

  • Port status: Shows whether the port is On or Off.

  • BPDU guard: Shows whether BPDU guard is On or Off.
  • Root guard: Shows whether Root guard is On or Off.
  • BPDU forward: Shows whether BPDU forwarding is On or Off.

To configure port settings, select the ports you want to configure and click Edit. Select the settings you want and click Apply.
