• Test Period—DNS query is sent periodically after every test period. The minimum test
period is 30 seconds.
• Maximum Failures—The WAN interface is considered down after the configured number
of DNS queries have failed to elicit a DNS reply from the configured DNS server. The
minimum number of failed DNS queries is four. The rollover link is brought up after this.
The minimum time to roll over after the primary WAN interface fails is two minutes (i.e., 30
second minimum test period times a minimum of four tests).
2. Once a rollover occurs, an alert will be generated (see “Getting E-Mail Notifications of Event
Logs and Alerts” on page 6-30). You should then get the failed WAN interface restored and
then force traffic back on the original primary WAN interface by reapplying the WAN Mode
menu shown in Figure 4-6.

binding on outbound traffic:
