Configuring The Lte Expansion Module For Primary Mode - Juniper NFX350 Hardware Manual

a total of 32 profiles, although only one profile can be active at a time. To configure the SIM profile, you
will require the following information from the service provider:
Username and password
Access Point Name (APN)
Authentication (Challenge Handshake Authentication Protocol (CHAP) or Password Authentication
Protocol (PAP))

Configuring the LTE Expansion Module for Primary Mode

Before you begin the procedure, ensure that the logical interface (dl0.0) is not configured as a backup. If
dl0.0 is configured as a backup option for any interface on the device, then this configuration overrides
the configuration outlined in this procedure, and the LTE expansion module 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 expansion module 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 physical interface:
user@host# set interfaces cl-1/1/0 dialer-options pool dialer-pool-number
NOTE: The dialer-pool-number is always 1 as there is only one LTE interface on the NFX350.
3. Configure the profile.
