Interfaces
Test the interface status: The interface is considered to be down based on:
n
l
l
10. Optional active recovery configuration parameters:
a. For Restart interface, enable to configure the device to restart the interface when its
connection is considered to have failed. This is useful for interfaces that may regain
connectivity after restarting, such as a cellular modem.
b. If Restart interface is enabled, for Restart fail count, type or select the number of times
that the Surelink test must fail before the interface is restarted. The default is 1.
c. For Reboot device, enable to instruct the device to reboot when the WAN connection is
considered to have failed.
Note
If both the Restart interface and Reboot device parameters are enabled, the
Reboot device parameter takes precedence.
d. If Reboot device is enabled, for Reboot fail count, type or select the number of times that
the Surelink test must fail before the device is rebooted. The default is 1.
e. Change the Interval between connectivity tests.
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 Interval to ten minutes, enter 10m or 600s.
The default is 15 minutes.
f. 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.
g. 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.
h. For Failed attempts, type the number of probe attempts before the WAN is considered to
have failed.
i. 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.
