• Delay—When the result of an IP SLA operation indicates that the state of the tracking 
object should change to X from Y, the tracking object performs the following actions:
- The state of the tracking object is not changed and the tracking object starts the 
delay timer for the interval.
- If during the time that the timer is set, the original state (Y) is received again, the 
timer is canceled, and the state remains Y. 
- If the delay timer is expired, the state of the tracking object is changed to X and the 
X state is passed to the associated applications.
