LR54 device to automatically recover the modem in the event that it cannot obtain an IP
address. See
Configure a Wireless Wide Area Network (WWAN)
for details about
SIM failover

5. By default, the device is configured to restart the interface when its connection is considered
to have failed.
To disable:
(config network interface my_wan ipv4 surelink)> restart false
(config network interface my_wan ipv4 surelink>
n
(Optional) Set the number of times that the Surelink test must fail before the interface
is restarted:
(config network interface my_wan ipv4 surelink)> restart_attempts
int
(config network interface my_wan ipv4 surelink>
where
int
is any number greater than
0
. The default is
1
.
6. (Optional) If the interface is a WWAN, by default, the device is configured to reset the modem
when its connection is considered to have failed.
To disable:
(config network interface my_wan ipv4 surelink)> reset_modem false
(config network interface my_wan ipv4 surelink>
7.

If
reset_modem
is enabled, set the number of times that Surelink tests must fail prior
to resetting the modem:
(config network interface my_wan ipv4 surelink)> reset_modem_
attempts
int
(config network interface my_wan ipv4 surelink>
where
int
is an integer between
1
through
5
. The default is
3
.
If the interface is a WWAN, SIM switching is enabled by default. To disable:
(config network interface my_wan ipv4 surelink)> switch_sim false
(config network interface my_wan ipv4 surelink>
Note
The SureLink
switch_sim
option differs from the
sim_failover
option, which is set
during WWAN configuration.
sim_failover
applies when the modem is unable to connect to a
cellular network, whereas
switch_sim
applies when the WWAN interface is failing SureLink
tests even though the modem is connected. See
Configure a Wireless Wide Area Network
for more information about the
sim_failover
option.

If
switch_sim
is enabled, set the number of times that Surelink tests must fail prior to
switching SIMS:
