Configuring the LTE Mini-PIM as the Primary Interface

 

Figure 1 illustrates a scenario where the LTE Mini-PIM is installed on a SRX320 Services Gateway and functions as the primary interface. This procedure assumes that the LTE Mini-PIM is installed in slot 1 on the SRX320 Services Gateway.

Note

The LTE Mini-PIM can be installed in any of the Mini-PIM slots on the SRX320, SRX340, SRX345, and SRX550M Services Gateways.

Before you begin the procedure, ensure that dl0.0 is not configured as a backup. If dl0.0 is configured as a backup option for any interface on the SRX Series device, then this configuration overrides the configuration outlined in this procedure, and the LTE Mini-PIM will function as a backup interface.

Use the show interfaces | display set | match backup-option | match dl0.0 command to check whether any interface uses dl0.0 as a backup interface. If dl0.0 is configured as a backup interface, then delete the configuration by issuing the following command:

delete interfaces interface-name unit 0 backup-options interface dl0.0

To configure the LTE Mini-PIM as a primary interface:

  1. Configure the dialer interface:
    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
  2. Configure the dialer pool for the LTE Mini-PIM physical interface:
    user@host# set interfaces cl-1/0/0 dialer-options pool number
  3. Configure the profile. The Subscriber Identity Module (SIM) uses a profile to establish a connection with the network. You can configure up to 16 profiles for each SIM card. The LTE Mini-PIM supports two SIM cards and so you can configure a total of 32 profiles, although only one profile can be active at a time.
    user@host# run request modem wireless create-profile profile-id profile-id cl-1/0/0 slot sim-slot-number access-point-name apn-name authentication-method none
    Note

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

  4. Verify that the profile is configured successfully:
    user@host# run show modem wireless profiles cl-1/0/0 slot 1
  5. Activate the SIM card:
    user@host# set interfaces cl-1/0/0 act-sim sim-slot-number
  6. 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-id
    user@host# set interfaces cl-1/0/0 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.

  7. Verify the status of the wireless network and dialer interface:
    user@host# run show modem wireless network
    user@host# run show interfaces dl0.0
    Note

    If the LTE Mini-PIM gets an IP address with a mask of /32 from the service provider, the user has to configure the default gateway information using the set interfaces cl-interface cellular-options sim sim-slot gateway ip-address/mask command to make the Mini-PIM accept the assigned IP address.
