HA Timers
High availability (HA) timers are used to detect a firewall
failure and trigger a failover. To reduce the complexity in configuring
HA timers, you can select from three profiles:
Recommended
, Aggressive
,
and Advanced
. These profiles auto-populate the
optimum HA timer values for the specific firewall platform to enable
a speedier HA deployment. Use the
Recommended
profile for typical
failover timer settings and the Aggressive
profile
for faster failover timer settings. The Advanced
profile
allows you to customize the timer values to suit your network requirements. HA Timer on the CN-Series
