Configure 210-SE LTE

The following procedure describes the steps and workflow to configure a 210-SE LTE appliance.


  1. Have a standard or 2FF SIM card (15 x 25 mm) from the preferred carrier.

  2. Have the Access Point Name (APN) information from the preferred carrier, if different from the default APN settings. The APN information varies from carrier to carrier.


See the 210-SE LTE QSG for more information about installing the appliance.

Add and Configure 210-SE LTE Appliance in the Network

  1. Insert the SIM card into the SIM card slot of the appliance. Only a standard or 2FF SIM card (15x25 mm) is supported.

  2. In the SD-WAN appliance GUI, navigate to Configuration > Appliance Settings > Network Adapters > Mobile Broadband.

    • If the APN settings are not the default, type the APN settings details.

    • Verify the status info page.

    • Status: Enabled means modem tries to establish the data session.
    • Card state: If present, it indicates that SIM is properly inserted.
    • Signal strength: Excellent, Good, Fair, Poor, or no signal.
    • Home network: Carrier of the SIM you inserted.
    • APN name: APN used by the LTE modem.
    • Session state: Connected indicates that the device has joined the network.

    If the session state is disconnected, check with carrier whether:

    • The account has been activated.

    • The data plan is enabled or not.

Manage Firmware

The AUTO-SIM option allows the LTE modem to choose the most matching firmware based on the SIM card inserted. Choose AUTO-SIM, if you are unsure which firmware to use. You can upload new firmware if available, using the Upload option.

Enable/Disable Modem

Enable/disable modem depending on your intent to use the LTE functionality. By default, the LTE modem is enabled.

Reboot Modem

Reboots the modem. It can take up to 3-5 minutes for the reboot operation to complete.

Refresh SIM

Use this option when you hot swap the SIM card to detect the new SIM card by the 210-SE LTE modem.

Configure 210-SE LTE Using CLI

To configure 210-SE LTE modem using the CLI:

  1. Log in to the SD-WAN appliance console.
  2. At the prompt, type the user name and password to gain CLI interface access.
  3. At the prompt, type the command lte. Type >help. This displays the list of LTE commands available for configuration.

The following table lists the LTE command descriptions.

Command Description
Help {lte>help} Lists the available LTE commands and parameters
Status {lte>status} Displays LTE connectivity status
Show {lte>show} Displays LTE settings
Disable {lte>disable} Disables LTE modem
Enable {lte>enable} Enables LTE modem
Apn {lte>apn} Configures APN settings information
Sim-power <off/on/reset> {lte>sim-power} Powers off sim card, Power on sim card, Refresh sim card
Reboot {lte>reboot} Restarts LTE modem
Ping {lte>ping} Pings LTE modem
List-fw {lte>list-fw} Lists firmware available on the R1 or R2 LTE modems
Apply-fw <fw> {lte>apply-fw} Applies firmware specific to a carrier

Configure MCN for LTE

To configure an MCN:

  1. Log in to the SD-WAN appliance GUI. Go to Configuration Editor. Complete configuration for the MCN site, see; Configure MCN.

  2. Ensure that you provide routable public IP address as part of WAN link configuration.

    You do not have to configure public IP address for client appliances.

Configure Branch for LTE

To configure the 210-SE LTE appliance as a branch site:

  1. In the SD-WAN appliance GUI, go to configuration editor. See; Configure Branch.

    • Create Interface Groups.

    • Create up to one Virtual Interface and one Interface Group for the LTE adapter to configure WAN link by selecting the following:

      • Ethernet Interface – LTE 1

      • Security- untrusted (default)

      • DHCP client - Enabled (default)

  2. Enable AutoDetect Public IP for WAN link configuration when configuring WAN link using the virtual interface created for LTE interface.

    localized image

  3. By default, when you try to configure WAN link using LTE interface, the WAN link is marked as Metered link and Last Resort Standby mode. You can change these default settings, if necessary.

    It is recommended to configure the active MTU detect option for the WAN links created using the LTE interface. Establishing dynamic virtual paths using LTE interface is not supported.

    The IP address and gateway address for the Access Interface of the WAN link need not be configured because it receives that information from the carrier through DHCP.

  4. Complete rest of the required Branch configuration for the 210-SE LTE appliance. See; configure Branch.
  5. Perform Change Management by uploading the SD-WAN software. See the Change Management procedure.
  6. Activate configuration through the Local Change Management process. When you perform Change Management, configuration is activated and required configuration is applied.

ZTD over LTE

Pre-requisites for enabling ZTD service over LTE:

  1. Install antenna and the SIM card for the 210-SE LTE appliance.

  2. Ensure that the SIM card has an activated data plan.

  3. Ensure that the management port is not connected.

    • If the management port is connected, disconnect the management port and then restart the appliance.

    • If a static IP address on the Management Interface is configured, you can configure the Management Interface with DHCP, apply the configuration, and then disconnect the Management port, and restart the appliance.

  4. Ensure that the 210-SE appliance configuration has internet service defined for LTE interface.

When the appliance is powered on, the ZTD service uses the LTE port to obtain the latest SD-WAN software and SD-WAN configuration only when the management port is not connected.

You can use the SD-WAN Center GUI to deploy and configure 210-SE LTE appliance for the ZTD service.

See the ZTD procedure for more information about deploying and configuring 210-SE LTE appliance using SD-WAN Center.

ZTD Service over Management Interface for 210-SE LTE Appliance

Connect the Management Port and use the standard ZTD procedure that is supported on all other non-LTE platforms.

Manage 210-SE LTE Using SD-WAN Center

The Mobile Broadband page under the Configuration tab in the SD-WAN Center GUI displays information about the LTE modem configuration. You can perform the LTE modem operations using the same options or buttons displayed in the SD-WAN 210-SE appliance GUI configuration for mobile broadband settings. LTE summary table lists 210-SE LTE appliances and you can select either single or multiple appliances to perform LTE modem operations.


Multi-region site support for uploading firmware is not available.
