SureLink.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (
WAN1
) and WWAN (
WWAN
). It is disabled for IPv6.
When SureLink is configured for Wireless WANs, SureLink tests are only run if the cellular
modem is connected and has an IP address. Use the
SIM failover
options to configure the
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

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 (WWAN)
for
