f. Set the number of probe attempts before the WAN is considered to have failed:
(config network interface my_wan ipv4 surelink)> attempts num
(config network interface my_wan ipv4 surelink>
The default is 3.
g. Set the amount of time that the device should wait for a response to a probe attempt
before considering it to have failed:
(config network interface my_wan ipv4 surelink)> timeout value
(config network interface my_wan ipv4 surelink>
where value is any number of weeks, days, hours, minutes, or seconds, and takes the
format number{w|d|h|m|s}.
For example, to set timeout to ten minutes, enter either 10m or 600s:
(config network interface my_wan ipv4 surelink)> timeout 600s
(config network interface my_wan ipv4 surelink)>
The default is 15 seconds.

Configure the device to reboot when a failure is detected
Using SureLink, you can configure the AnywhereUSB Plus 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 WAN (ETH1) and WWAN (Modem). 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
AnywhereUSB Plus 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.
