Configure the device to reboot when a failure is detected
Using SureLink, you can configure the IX14 device to reboot when it has determined that an interface
has failed.
Required configuration items
n
Enable SureLink.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured Modem interface. 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 IX14
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.
n
Enable device reboot upon interface failure.
n
The type of probe test to be performed, one of:
l
Test another interface's status: Used to create a failover or coupled relationship between
two interfaces. Requires the name of the alternate interface, the IP version to be tested,
and the expected status of the alternate interface (either up or down).
l
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
configured for the WAN.
l
HTTP test: Requires the URLof the host to be tested.
l
Test DNS servers configured for this interface: Tests communication with this interface's
DNS servers that are either provided by DHCP, or statically configured.
l
Interface status: Determines if the interface has an IP address assigned to it, that the
physical link is up, and that a route is present to send traffic out of the network interface.
Additional configuration items

See Configure SureLink active recovery to detect modem failures for optional SureLink
configuration parameters.
