default test period is 30 seconds.
6. Enter the Maximum Failover amount. The WAN interface is considered down after the
configured number of queries have failed to elicit a reply. The rollover link is brought up after
this. The Failover default is 4 failures.
The default time to roll over after the primary WAN interface fails is 2 minutes (a 30-second
minimum test period, times a minimum of 4 tests).
7. Click Apply to save your settings.
8. Click Reset to revert to the previous settings.
Once a rollover occurs, an alert will be generated (see “Activating Notification of Events and
Alerts” on page 6-23). When notified that the failed WAN interface has been restored, you can
force traffic back on the original primary WAN interface by reapplying the Auto-Rollover settings
in the WAN Port Mode menu.
