Configuring the LTE Mini-PIM on SRX Series Devices

Configuring the LTE Mini-PIM

To configure the Mini-PIM:

Note:

If a services gateway with factory-default settings is powered on with the LTE Mini-PIM installed in slot 1, the dialer interface is triggered to dial automatically. This functionality is applicable only if the Mini-PIM is installed in slot 1. If the Mini-PIM is installed in any other slot, then you will need to manually configure the cl-slot-number/0/0 interface to be associated with the dialer interface.

  1. Configure the dialer pool:

    user@host# set interfaces cl-slot-number/0/0 dialer-options pool number priority number

  2. Configure the profile:

    user@host# request modem wireless create-profile profile-id profile-id access-point-name l3vpn.corp authentication-method chap sip-user-id user@myvpn.net sip-password password

  3. Activate the SIM:

    user@host# set interfaces cl-slot-number/0/0 act-sim sim-slot-number

    Note:

    Only one SIM card can be active at a time. If you have installed a secondary SIM card, it will be automatically activated when the signal strength for the primary SIM card is low.
  4. Select the profile and configure the radio access type for the SIM card:

    user@host# set interfaces cl-slot-number/0/0 cellular-options sim sim-slot-number select-profile profile-id profile-id

    user@host# set interfaces cl-slot-number/0/0 cellular-options sim sim-slot-number radio-access automatic

    Note:

    If a SIM card is installed in the second slot, then select the profile and configure the radio access type for the secondary SIM card as well.

  5. Configure the dialer interface:

    • Always-On mode:

      user@host# set interfaces dl0 unit 0 family inet negotiate-address

      user@host# set interfaces dl0 unit 0 family inet6 negotiate-address

      user@host# set interfaces dl0 unit 0 dialer-options pool dialer-pool-number

      user@host# set interfaces dl0 unit 0 dialer-options dial-string dial-number

      user@host# set interfaces dl0 unit 0 dialer-options always-on

    • Dial-on-Demand mode:

      user@host# set interfaces dl0 unit 0 family inet negotiate-address

      user@host# set interfaces dl0 unit 0 family inet filter dialer dialer-filter-name

      user@host# set interfaces dl0 unit 0 dialer-options pool dialer-pool-number

      user@host# set interfaces dl0 unit 0 dialer-options dial-string dial-number

    • Backup mode:

      user@host# set interfaces <interface-name> unit 0 backup-options interface dl0.0

      user@host# set interfaces dl0 unit 0 dialer-options dial-string dial-number

  6. Commit the configuration:
    user@host# commit

Configuring a Static Route on the Dialer Interface

A static route enables the dialer interface to forward packets to a specific destination other than the default route. Static routes are manually configured and entered into the routing table. You can configure a static route on the dialer interface by using the set interfaces dl0 unit 0 dialer-options route destination-ip-address command.

After you configure a static route, make sure that the route appears in the routing table of the device by using the show route command. Note that the static route appears in the routing table only after the LTE Mini-PIM is connected to the network.
