Test DNS servers configured for this interface : Tests connectivity by sending a DNS
query to the DNS servers configured for this interface.
n
Test the interface status : The interface is considered to be down based on:
l
Down time : The amount of time that the interface can be down before this test is
considered 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 Down time to ten minutes, enter 10m or 600s .
The default is 60 seconds.
l
Initial connection time : The amount of time to wait for an initial connection to the
interface before this test is considered to have failed.
Allowed values are any number of weeks, days, hours, minutes, or seconds, and take

targets.
c. For Attempts , type the number of probe attempts before the WAN is considered to have
failed.
d. For Response timeout , type the amount of time that the device should wait for a
