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

Verify the status of the wireless network and dialer interface:
user@host# run show modem wireless network
user@host# run show interfaces dl0.0
Configuring the LTE Expansion Module for Dial-on-Demand Mode
When the LTE expansion module is configured as a primary interface, it can function
either in always-on mode or in dial-on-demand mode. In always-on mode, the interface
remains connected to the network whereas In dial-on-demand mode, the connection is
established only when needed.
In dial-on-demand mode, the dialer interface is enabled only when network traffic
configured as an “interesting traffic” arrives on the network. Interesting traffic triggers or
activates the wireless WAN connection. You define an interesting packet by using the
dialer filter. To configure dial-on-demand by using a dialer filter, you first configure the
dialer filter and then apply the filter to the dialer interface.
Once the traffic is sent over the network, an inactivity timer is triggered and the connection
is closed after the timer expires.
NOTE: The dial-on-demand mode is supported only if the LTE expansion
module is configured as a primary interface.
To configure the LTE expansion module as a dial-on-demand 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 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
2.
(Optional) Configure the
idle-timeout
value, which determines the duration for which
the connection will remain enabled in the absence of interesting traffic.
user@host# set interfaces dl0 unit 0 dialer-options idle-timeout idle-timeout-value
3.
Configure the dialer pool for the LTE physical interface:
user@host# set interfaces cl-1/1/0 dialer-options pool dialer-pool-number
