Configuring the Switch

The following configuration is suitable for transforming an existing network into a ring topology.

1. On a computer that is connected to the managed switch or LAN network, open a web browser and enter the IP address of the managed switch.

   Enter the user ID and password that are known or provided in the switch user guide (default identifiers).

2. Enable protocol support for the Rapid Spanning Tree Protocol (RSTP). The Spanning Tree Protocol (RSTP) is not supported for the creation of a ring topology on EVlink Pro AC charging stations.

   Configure the following RSTP parameters according to the values indicated.

   Parameter	Value
   Bridge Priority	< 32768
   Max age	≥ Number of chargers in the ring + 1

   For example, the following RSTP configurations meet the expected values for a ring topology of 20 charging stations.

   Parameter	Value
   Bridge Priority	4096
   Max age	21

   Disable anti-loop protection features (such as Cisco BPDU Guard / BPDU Filter or equivalent) on the switch ports connected to the ring.

3. Save the new managed switch configuration. If necessary, restart to apply the changes.
