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:
- Create the dialer interface.[edit interfaces]user@host# set interfaces dl0 unit 0 family inet negotiate-addressuser@host# set interfaces dl0 unit 0 family inet6 negotiate-addressuser@host# set interfaces dl0 unit 0 dialer-options pool dialer-pool-numberuser@host# set interfaces dl0 unit 0 dialer-options dial-string dial-number
- Define the dialer pool for the LTE Mini-PIM physical interface.user@host# set interfaces cl-1/0/0 dialer-options pool dialer-pool-number
- 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.
user@host# run request modem wireless create-profile profile-id profile-id cl-1/0/0 slot sim-slot-number access-point-name l3vpn.corp authentication-method none - Activate the SIM card.user@host# set interfaces cl-1/0/0 act-sim sim-slot-number
- Select the profile and configure the radio access type
for the SIM card.user@host# set interfaces cl-1/0/0 cellular-options sim sim-slot-number select-profile profile-id profile-iduser@host# set interfaces cl-1/0/0 cellular-options sim sim-slot-number radio-access automatic
- Specify Ethernet interface as the primary interface, which
connects to the wireless network. Specify the dl0 interface as the
backup interface.user@host# set interfaces ge-0/0/1 unit 0 family inet address 192.168.2.1/24user@host# set interfaces ge-0/0/1 unit 0 backup-options interface dl0.0
Results
From configuration mode, confirm your configuration by entering the show interfaces dl0.0 command. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

Verification of the configured profile
Purpose
Verify that the profile is configured successfully.
Action
From operational mode, run the show modem wireless profiles cl-1/0/0 slot 1 command.
