Technical Tip: How to configure HA failover delay for monitored ports

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.
