Monitor Fail Hold Up Time (ms)

Interval during which the firewall will remain active following a path monitor or link monitor failure. This setting is recommended to avoid an HA failover due to the occasional flapping of neighboring devices.

Preemption Hold Time (min)

Time that a passive or active-secondary firewall will wait before taking over as the active or active-primary firewall.

Heartbeat Interval (ms)

Frequency at which the HA peers exchange heartbeat messages in the form of an ICMP (ping).

Promotion Hold Time (ms)

Time that the passive firewall (in active/passive mode) or the active-secondary firewall (in active/active mode) will wait before taking over as the active or active-primary firewall after communications with the HA peer have been lost. This hold time will begin only after the peer failure declaration has been made.

Additional Master Hold Up Time (ms)

Time interval in milliseconds that is applied to the same event as Monitor Fail Hold Up Time (range is 0 to 60,000; default is 500). The additional time interval is applied only to the active firewall in active/passive mode and to the active-primary firewall in active/active mode. This timer is recommended to avoid a failover when both firewalls experience the same link/path monitor failure simultaneously.

Hello Interval (ms)

Interval in milliseconds between hello packets that are sent to verify that the HA functionality on the other firewall is operational (range is 8,000 to 60,000; default is 8,000).
