Configuring network interfaces

Depending on the network interfaces supported by your base station, you may configure one or more of the following interfaces:

By default, the base station image is configured with DHCP activated, so the IP address is automatically allocated by the DHCP server of your network. If you want to switch from DHCP to static IP address, see Changing IP address allocation strategy.

If your base station model supports several network interfaces, ThingPark allows you to configure one interface as primary and another as a secondary one. Thanks to the automatic failover/failback mechanisms between primary and secondary interfaces, the primary network interface shall be privileged by the LRR software if it is up and running; otherwise, the secondary interface shall be used if up/ready. To learn more about interface failover configuration, see IP failover.

When you are done with all your System Configuration, do not forget to apply your new configuration to your base station. To learn more, see Apply/Commit/Rollback mechanism.

The base station image uses DHCP mode by default. Follow these steps to configure a fixed IP address instead of DHCP:

  1. From SUPLOG’s root menu, choose System configuration, then Network, then Network interfaces.

  1. Select the network interface that you want to configure.

    Note The interface details are displayed for the interface shown with (*).

    To display another interface, use the arrows to go to this interface then press the <Space> bar to select it.

  2. To toggle the activation state of this interface, go to “Active” (use the <Tab> key to navigate through the fields) and press the <Space> bar to change the current value. An active interface should have an [X].

  3. To move from DHCP to fixed IP:

    1. Go to “DHCP activated” and use the <Space> bar disable it. The field should look like: [ ]

    2. Configure IP address, Netmask, Broadcast, Gateway, DNS list fields.

  4. Repeat steps 2 to 4 above for each network interface that you want to switch to static IP instead of DHCP.

Once you are done with your changes in this menu, click “Confirm” to save your configuration.

Note At this stage, the configuration is only saved by the system, but it has not yet been applied to the base station. To learn more, see Apply/Commit/Rollback mechanism.

Follow these steps to configure cellular network interface:

  1. From SUPLOG’s root menu, choose System configuration, then Network, then Cellular:

  2. Configure your cellular settings (use <Tab> key to navigate between fields):

    1. Available, should have an [X].

    2. Autoconf is not supported in this release.

    3. Fill the APN, PIN, user and password, and press <Enter> to validate your choice.

  3. Once you are done with your changes in this menu, click "Confirm" to save your configuration.

    Note At this stage, the configuration is only saved by the system, but it has not yet been applied to the base station. To learn more, see Apply/Commit/Rollback mechanism.

    Note To activate the cellular backhaul, it is also necessary to configure additionally cellular 3G/4G modem as your primary or secondary interface, go to IP failover.

Some base station models support WiFi backhaul option, this is the case for Kerlink iFemtocell and Ufispace Pico/Enterprise models. Follow these steps to configure WiFi network interface:

  1. From SUPLOG’s root menu, choose System configuration, then Network, then Wifi:

  1. Configure your WiFi settings (use <Tab> key to navigate between fields):

  2. Available, should have an [X].

  3. Fill the SSID, Security protocol and security Key and press <Enter> to validate your choice.

  4. Once you are done with your changes in this menu, click “Confirm” to save your configuration.

    Note At this stage, the configuration is only saved by the system, but it has not yet been applied to the base station. To learn more, see Apply/Commit/Rollback mechanism.

    Note To activate the WiFi backhaul, it is also necessary to configure additionally WiFi as your primary or secondary interface, go to IP failover.

Once you are done configuring each individual interface, as explained in the previous sections, you should now configure how those interfaces are used by your base station; that is to say, determine which interface is primary and which one is secondary.

To do this:

  1. From SUPLOG’s root menu, choose System configuration, then IP failover:

  1. Go to Interface (through the <Tab> key) then select the interface you want to configure.

    Note “Status” and “Bandwidth” fields are displayed for the interface shown with (*). To display another interface, use the arrows to go to this interface then press the <Space> bar to select it.

    • To make an interface the primary one, choose this interface (should be displayed with (*)) then go to Status (via <Tab> key) and select “primary” then press <Enter> key.

    • Likewise, to configure an interface as a secondary one, choose this interface, then select “secondary” from the Status field.

    • To completely deactivate a network interface, select it and set Status = not-used.

    For each interface, you may also set the Bandwidth constraint to allow ThingPark LRR to control the backhaul overhead accordingly, by adapting the ICMP ping periodicity. Typical configuration would be:

    • “no-constraint” for ethernet and WiFi

    • “limited” for cellular 3G/4G interfaces

    • “very limited” for satellite type of backhaul.

Note The ICMP destinations used to validate the state of the interface are automatically set as follows:

  • If PKI is active (meaning backhaul connection is secured either by IPSec or TLS): ICMP pings the ThingPark core network component that terminates the IPSec/TLS connection (also known as SLRC).

  • Otherwise, ICPM pings the ThingPark Network Server (also known as LRC).

 

In this same “IP Failover” menu, you can configure the direct SSH access strategy to your base station:

  • If you want your base station to be accessible through SSH at any time, from any remote client (whatever located in the same LAN or not), then set Local SSH port = “keep open”.

  • Otherwise, if you want your base station to open a local SSH port - accessible by any remote client – only for sake of debugging backhaul connection issues, that is when the base station loses connection with ThingPark core network, then set Local SSH port = “close when stable”.

    Note that with this configuration, the base station remains accessible with SSH at any time, but only to remote clients located in the same LAN as the base station (for clients having a private IP address).

Note Whatever the configuration you select here, your base station’s SUPLOG shall remain remotely accessible from the ThingPark GUI, through reverse SSH.

Once you are done with your changes in this menu, click “Confirm” to save your configuration.

An LRR restart will need to be confirmed. Depending on your local network, it may happen that the local IP of your base station is changed and that you need to open a new local SSH connection to continue your setup.

Note At this stage, the configuration is only saved by the system, but it has not yet been applied to the base station. To learn more, see Apply/Commit/Rollback mechanism.
