The following four Link Test options are used if the Ping or TCP Connection Link Test is selected.




Repeat the test every: N seconds: The time interval (N) in seconds between the end of
a successful link test and the start of the next link test for the network interface. This
interval is used only after a successful test.
Shorter intervals verify the link more often, but they also increase the packet traffic over
the network interface being tested. The frequency of tests should be considered carefully
for network connections such as Mobile (cellular) connections, which may be
expensive, depending on the service plan in effect with your mobile service provider.
On test failure, retry every: N seconds: The time interval (N) in seconds between the
end of a failed link test and the start of the next link test for the network interface. This
interval is used after a failed test, but only until the “Not Responding” (consecutive
failures) threshold has been reached.
A possible strategy is to configure a shorter Retry interval than the Success interval, to
more quickly test the network connection to determine whether it is truly not working or
there was just a transient test failure. Determining the validity of the link helps failover
determine whether it is necessary to reconfigure the default gateway.
Report Not Responding after: N consecutive failures: The threshold (N) in
consecutive link test failures at which time the network interface is reported to failover
as “Not Responding”. Upon receiving such a report, failover may determine that the
default gateway should be reconfigured. The count of consecutive failures is reset to
zero when a successful link test completes, or when the network interface is
reconfigured or its connection is restarted (such as a mobile PPP connection).
When Not Responding, retry every: N seconds: The time interval (N) in seconds
between the end of a failed link test and the start of the next link test for the network
interface. This interval is used after a failed test, but only after the “Not Responding”
(consecutive failures) threshold has been reached.
