Interfaces
b. If more than one test target is configured, for Success condition, determine whether the
interface should fail over based on the failure of one of the test targets, or all of the test
targets.
c. For Pass threshold, type or select the number of times that the test must pass after
failure, before the interface is determined to be working and is reinstated.
d. For Failed attempts, type the number of probe attempts before the WAN is considered to
have failed.
e. For Response timeout, type the amount of time that the device should wait for a response
to a probe attempt before considering it to have failed.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and take the
format number{w|d|h|m|s}.
For example, to set Response timeout to ten minutes, enter 10m or 600s.
The default is 15 seconds.

Command line
Active recovery can be configured for both IPv4 and IPv6. These instructions are for IPv4; to configure
IPv6 active recovery, replace ipv4 in the command line with ipv6.

Depending on your device configuration, you may be presented with an Access selection
menu. Type admin to access the Admin CLI.
2. At the command line, type config to enter configuration mode:

a Wireless Wide Area Network
To edit an existing WAN or WWAN, change to the WAN or WWAN's node in the
n
configuration schema. For example, for a WAN or WWAN named my_wan, change to the
my_wan node in the configuration schema:
(config)> network interface my_wan
(config network interface my_wan)>
4. Enable SureLink.
SureLink can be enabled for both IPv4 and IPv6 configurations. By default, SureLink is enabled
for IPv4 for the preconfigured WAN (wan1) and WWANs (wwan1 and, for dual-cellular models,
wwan2). It is disabled for IPv6.
