Example: Configure LTE Mini-PIM as a Backup Interface

 

This example shows how to configure the LTE Mini-PIM as a backup interface. If the primary interface fails, the Mini-PIM connects to the network and remains online only until the primary interface becomes functional. The dialer interface is enabled only when the primary interface fails. In this scenario, the Mini-PIM is installed on slot 1.

Configuration

CLI Quick Configuration

To quickly configure this example, copy the following command, paste it into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the command into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

Configure the LTE Mini-PIM as a Backup Interface

Step-by-Step Procedure

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the CLI User Guide.

To configure LTE Mini-PIM as a backup interface:

  1. Create the dialer interface.
  2. Define the dialer pool for the LTE Mini-PIM physical interface.
  3. Create and configure the profile on the SIM cards.

    sim-slot-number is the slot on the Mini-PIM in which the SIM card is inserted.

  4. Activate the SIM card.
  5. Select the profile and configure the radio access type for the SIM card.
  6. Specify Ethernet interface as the primary interface, which connects to the wireless network. Specify the dl0 interface as the backup interface.
