Description | This article describes how to configure HA failover delay when monitored interface go down. |
Scope | FortiGate 7.0 and above. |
Solution |
In the following example, the failover-hold-time has been set to 30 seconds. The value can be set from 0 to 300.
# config system ha set failover-hold-time <integer> end
Results. Before port3 at Bezza-kvm36 go down:
After port3 at Bezza-kvm36 went down:
Fail-over occurred after 30 seconds:
Note. The same command is also the solution when there is a premature failback after a monitored link goes down (i.e. when a switch connected to a particular unit was rebooted or its interface flapped).
Premature fail-back problem: A second after FGVM020000-----7 became the master due to port3 being down, FGVM020000-----2 became master again.
Adding failover-hold-time will avoid flips caused by monitor interface failure. |
