> 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.
