2-12 Connecting the FVX538 to the Internet
v1.0, August 2006
• Ping to this IP address – Enter a public IP address that will not reject the Ping request or
will not consider the traffic abuse. Queries are sent to this server through the WAN
interface being monitored.
5. Enter a Test Period in seconds. DNS query is sent periodically after every test period. The
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 “E-Mail Notifications of Event Logs and
Alerts” on page 4-31). 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.
