Failover Timers Configuration Dialog Box
Failover Timers Configuration Dialog Box
You can access the Failover Timers Configuration Dialog Box by selecting Primary in the Failover Type pulldown in the Link Configuration: WAN Dialog Box (under WAN/Link Configuration), and then selecting the Timers button.
>Backup Enable Timer
This is the number of seconds from the time the Primary port’s line is detected as being down until traffic is diverted to the Backup port. This is also known as the “failover time.”
>Backup Disable Timer
This is the number of seconds from the time the Primary port’s line is detected as having come back up until traffic is restored to the Primary port. This is also known as the “failback time” and is used to keep the router from switching out of failover mode too soon if the Primary link has an intermittent connection.
Backup Init Timer
This is the number of seconds after router startup before failover operation will go into effect. This timer allows PPP or Frame Relay communications time to stabilize before Primary port line status is checked.
