Configure the device to reboot when a failure is detected
Using SureLink, you can configure the IX10 device to reboot when it has determined that an interface
has failed.
Required configuration items
n
By default, SureLink is enabled for the preconfigured Modem interface. The default
configuration tests the DNS servers configured for the interface.
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 IX10
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.

Enable device reboot upon interface failure.

The type of tests to be performed:
l
Ping test: Uses ICMP to determine connectivity. The default behavior is to ping the
interface gateway, which means that an initial traceroute is sent to the hostname or IP
address configured in the SureLink advanced settings, and then the first hop in that route
is used for the ping test.
l
DNS test: Performs a DNS query to the named DNS server.
l
HTTP test: Uses HTTP(s) GET requests to determine connectivity to the configured web
server.
l
Test DNS servers configured for this interface: Tests communication with DNS servers
that are either provided by DHCP, or statically configured for this interface.
l
Test the interface status: Tests the current status of the interface. The test fails if the
interface is down. Failing this test infers that all other tests fail.
l
Custom test: Tests the interface with custom commands.
l
TCP connection test: Tests that the interface can reach a destination port on the
configured host.
l
Test another interface's status: Tests the status of another interface.
