Configure the device to reboot when a failure is detected

Using SureLink, you can configure the LR54 device to reboot when it has determined that an interface
has failed.
Required configuration items
Enable SureLink.
n
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
Enable device reboot upon interface failure.

and the expected status of the alternate interface (either up or down).
Ping: Requires the hostname or IP address of the host to be pinged.
l
DNS query: You can perform a DNS query to a named DNS server, or to the DNS servers
l
configured for the WAN.
HTTP test: Requires the URL of the host to be tested.
l

l
DNS servers that are either provided by DHCP, or statically configured.
Interface status: Determines if the interface has an IP address assigned to it, that the
l
physical link is up, and that a route is present to send traffic out of the network interface.
