Hi,
The failover feature in the Cisco PIX Firewall monitors failover communication, the power
status of the other unit, and hello packets received at each interface. If two consecutive hello
packets are not received within an amount of time determined by the failover feature,
failover starts testing the interfaces to determine which unit has failed and transfers active
control to the standby unit.
The "failover poll seconds" command allows you to determine how long failover waits
before sending special failover “hello” packets between the primary and standby units over
all network interfaces and the failover cable. The default is 15 seconds. The minimum value
is 3 seconds, and the maximum is 15 seconds.
HTH,
Haitham
