Hi ,

DFM performs the following actions:

1. As  soon as DFM receives a Link Down Trap from a physical port or interface  (or a Warm Start/Cold Start Trap from a system), DFM begins counting  the traps.

2. When  DFM receives two or more traps within 30 seconds, it considers the  network adapter or system to be at fault and DFM generates a Repeated  Restarts event or a Flapping event.

The minimum traps parameter is set by the Link trap threshold or Restart  trap threshold and the minimum seconds parameter is set by the Link  trap window or restart trap window. DFM must receive a minimum of two  traps within the trap window in a minimum of 30 seconds before it  considers an element at fault.

3. DFM continues to receive traps for 80 seconds after the initial trap, resulting in a stable time of 80 seconds.

The stable time is the amount of time that DFM waits before it clears the Repeated Restarts event or Flapping event.
