1. Web Page Configuration

(1) Browser Login

The default switch IP is 192.168.1.254; default username: admin; default password: admin.

2. Enable RSTP Ring Network Function

The RS636 has RSTP ring network enabled by default, but the ring network ports are disabled by default.

Enter the switch IP in your browser to access the management page. Navigate to Basic Settings / STP / RSTP Settings / Spanning Tree Settings to enable the spanning tree.

(3) Set the number of RSTP ring network switches.

① RSTP ring network setup for 20 switches.

1) Set the forwarding delay to 15 seconds, maximum aging time to 20 seconds, and maximum hops to 20 (default configuration).

② RSTP ring network setup for 40 switches.

1) Set the forwarding delay to 30 seconds, maximum aging time to 40 seconds, and maximum hops to 40.

(4) Select Ring Network Ports.

① Go to Device Control / STP / Port Configuration.

② Select the ports to enable for the ring network; all switch ports support ring network configuration.

③ By default, optical ports will all have the ring network enabled; select ge5-6 port type and modify it to be a non-edge port, then click Modify.

(5) Save the configuration:

① After configuring the ring network port functionality, it is essential to save the settings; otherwise, the switch will revert to defaults upon reboot.

② Go to System Tools / Save Configuration / click the Save button.

2. Quickly Modify Switch IP

(1) The default IP for the switch is 192.168.1.254.

1) If the switch has not modified the management IP, it may cause conflicts, preventing access to which switch one has logged into.

2) Open the WT-SWITCH app to scan all switches on the network;

3) Modify the management IP address of the switch according to the network planning table;

4) When using the WT-SWITCH app to scan switches, ensure to turn off the firewall function (Control Panel > System and Security > Windows Defender Firewall > Custom Settings);

3. Switch Root Bridge Settings

(1) When is it necessary to set the root bridge - root switch?

1) In a single ring state, no need to set a root switch;

2) In a multi-ring state, it is best to set the center as the root switch (root bridge); only one root switch is allowed within the multi-ring;

Root Switch Priority: 4096 (only one allowed)

Other Switch Priority: 32768 (default)

Root Switch Priority: 4096

Other Switch Priority: 32768 (default)

(2) View the learning status of the ring network switches.

1) The center switch learns the root bridge as its own MAC; The bridge ID should be the same as the root bridge ID;

2) Other switches in the ring will have their bridge ID as their own MAC information, while the root bridge ID will be that of the central switch's MAC information. If two root bridge IDs appear in a multi-ring, a broadcast storm will occur in the network.

5. How to Obtain Adjacent Switch IPs

(1) Why use LLDP Protocol (Link Layer Discovery Protocol)?

1) Switches often have incomplete configurations or configurations that are not saved, causing them to revert to defaults upon reboot, which can also lead to issues like storms in the ring network after running for some time.

2) Technical engineers need to physically visit each switch installation point to configure switch functions, which wastes time.

3) If the optical connections for the industrial switches are functioning correctly, engineers can configure each switch remotely from the control room, maximizing the use of every switch feature to reduce workload and enhance operational skills. The switches are set to enable LLDP discovery protocol by default. By connecting a debugging computer to the ring network switch in the central control room, you can log into the webpage and find LLDP protocol information, confirming the next switch's IP and other details. By doing so for each switch, one can summarize the IP addresses of the switches at each point based on the installation diagram and create an IP planning table.

4) The RS636 has LLDP Discovery Protocol enabled by default.

2) View LLDP Neighbor Information.

1) Go to Basic Settings / LLDP Settings / LLDP Information to view details.

2) Check the LLDP information table to view the IP addresses of adjacent switches connected via optical ports.

a. Ge10 connected to the next switch IP - 192.168.1.5

b. Ge9 connected to the next switch IP - 192.168.1.2
