Example: Configure two LANs

The default configuration of the TX54 consists of one LAN (LAN1), which is configured to use the LAN1 bridge. Its Setup IP address is 192.168.2.1, and it has its DHCP server enabled. The default configuration of the LAN1 bridge consists of the following devices:

In this example, we will create a second bridge, called LAN2. We will then create a second LAN, LAN2, and configure LAN2 to use the new bridge.

Note To avoid potential problems with access to the device while performing these procedures, you should use an Ethernet connection connected to LAN1 through the ETH2 Ethernet port, or, if using the command line, use the serial port.

Task one: Configure bridges

In this task, we will create a new bridge and configure the LAN1 and LAN2 bridges to use the following devices:

In task two, we will assign the new LAN2 bridge to a LAN.

 

  1. Log into Digi Remote Manager, or log into the local Web UI as a user with full Admin access rights.
  2. Access the device configuration:

    1. Locate your device as described in Use Digi Remote Manager to view and manage your device.
    2. Click the Device ID.
    3. Click Settings.
    4. Click to expand Config.

    1. On the menu, click System. Under Configuration, click Device Configuration.

      The Configuration window is displayed.

  3. Click Configuration > Network > Bridges > LAN1 > Devices.
  4. Delete the ETH3, ETH4, and Digi AP (Wi-Fi2) (dual-Wi-Fi models only) devices from the bridge:
    1. Click the menu icon (...) next to the ETH3 device and select Delete.

    2. Repeat for the ETH4 and Digi AP (Wi-Fi2) devices.
  5. Create a new bridge:
    1. For Add Bridge, type LAN2 and click .

    2. Add the ETH3 and Digi AP (Wi-Fi2) devices to the bridge:
      1. Click to expand Devices.
      2. For Add Device:, click .

      3. For Device, select Ethernet: ETH3.

      4. (Dual-Wi-Fi models only) For Add device, click again and select WiFi access point: Digi AP (Wi-Fi2).
  6. Click Apply to save the configuration and apply the change.

 

Note The example command and output in this procedure are based on a dual-Wifi configuration. Commands and output will vary slightly if your TX54 device is a single-WiFi model.

  1. Select the device in Remote Manager and click Actions > Open Console, or log into the TX54 local command line as a user with full Admin access rights.

    Depending on your device configuration, you may be presented with an Access selection menu. Type admin to access the Admin CLI.

  2. At the command line, type config to enter configuration mode:

    > config
(config)>

  3. Display a list of devices currently configured for the LAN1 bridge:
    (config)> show network bridge lan1 device
0 /network/device/eth2
1 /network/device/eth3
2 /network/device/eth4
3 /network/wireless/ap/digi_ap1
4 /network/wireless/ap/digi_ap2
(config)>
  4. Remove devices from the LAN1 bridge that will be used by other interfaces in this configuration.
    1. If your device is a dual-WiFi model, remove the Digi AP (Wi-Fi2) access point (/network/wireless/ap/digi_ap2) from the bridge, using its index number, 4, as determined above with the show command:
      (config)> del network bridge lan1 device 4
(config)>
    2. Remove the ETH4 device (/network/device/eth4) from the bridge, using its index number, 2, as determined above with the show command:
      (config)> del network bridge lan1 device 2
(config)>
    3. Remove the ETH3 device (/network/device/eth3) from the bridge, using its index number, 1, as determined above with the show command:
      (config)> del network bridge lan1 device 1
(config)>
    4. Use the show command again to verify that the LAN1 bridge now has only two devices, ETH2 and Digi AP (Wi-Fi1):
      (config)> show network bridge lan1 device
0 /network/device/eth2
1 /network/wireless/ap/digi_ap1
(config)>
  5. Create a new bridge, named LAN2:
    (config)> add network bridge LAN2
(config network bridge LAN2)>
  6. Add devices to the bridge:
    1. View available devices and the proper syntax by using the add device command with the TAB autocomplete feature:
      (config network bridge LAN2)> add device end <TAB>
(config network bridge LAN2)> add device end /network/<TAB>
/network/device/eth1          /network/device/eth2          /network/device/eth3
/network/device/eth4          /network/device/loopback      /network/bridge/LAN2
/network/bridge/lan1          /network/wireless/ap/digi_ap1 /network/wireless/ap/digi_ap2
(config network bridge LAN2)>
    2. Add the ETH3 device to the bridge:
      (config network bridge LAN2)> add device end /network/device/eth3
(config network bridge LAN2)>
    3. If your device is a dual-WiFi model, add the Digi AP (Wi-Fi2) access point to the bridge:
      (config network bridge LAN2)> add device end /network/wireless/ap/digi_ap2
(config network bridge LAN2)>
    4. Use the show command again to verify that the LAN2 bridge now has two devices, ETH3 and Digi AP (Wi-Fi2):
      (config network bridge LAN2)> show network bridge lan2 device
0 /network/device/eth3
1 /network/wireless/ap/digi_ap2
(config network bridge LAN2)>
  7. Save the configuration and apply the change.
    (config network bridge LAN2)> save
Configuration saved.
>
  8. Type exit to exit the Admin CLI.

    Depending on your device configuration, you may be presented with an Access selection menu. Type quit to disconnect from the device.
