Initial Switch Configuration

Before configuring ERPS (Ethernet Ring Protection Switching) through the web interface, configure your switches as follows. In this example, there are three switches getting configured.
  1. Because all switches have the same IP initially, it is best to connect to the switch locally and then configure its IP.
  2. While you are in the CLI:
    1. Disable Spanning Tree by entering no spanning-tree.
      Spanning Tree is enabled by default. Disabling it ensures STP (Spanning Tree Protocol) does not conflict with ERPS.


      You must be in Configuration Mode to run this command (see "Execution Modes" in the ISW-Series Managed Industrial Ethernet Switch Command Reference Guide.
    2. Disable LLDP (Link Layer Discovery Protocol) by entering the commands no lldp receive and no lldp transmit.
    3. Disable Loop Protection by entering no loop-protect.
  3. Connect switch 1 to switch 2, and switch 1 to switch 3.


    Do not connect switch 2 to switch 3, otherwise you will create a loop.
  4. Access switch 1 by entering the IP address into a web browser (see Browser Support).
  5. Enable VLAN tag aware. To do this:
    1. Navigate to Configuration > VLANs.
    2. Configure the ports as follows:
      Port Mode Port Type
      1 Hybrid C-Port
      2 Hybrid C-Port
    3. Click ../Graphics/save_small.png.
    4. Repeat for the remaining switches.
