user@host# run show modem wireless network
user@host# run show interfaces dl0.0

Configuring the LTE Expansion Module for Backup Mode

You can configure the LTE expansion module as a backup interface. If the primary interface fails, the LTE
expansion module 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.
