Re: Frame-relay end-to-end keepalive

Hi Bryan,

  Thanks for the reply and clarification.

   I think based on your clarification,I may misunderstood the definition of
"event window" also.Let me try to state my understanding on event window and
if wrong kindly correct me.

"The number of events necessary to change the keepalive status of the PVC
from UP to Down state".So if we set event window to 5,that means 5
events(Keep alive misses or not got response from the receiving side for the
keepalive messages send by the sending side) should have occured to make the
PVC from up to down state.Is my understanding right ? ...If so, then I am
missing the error threshold clarification you provided below,Sure I am
missing something.Kindly clarify the same.

Once again thanks for the response.

Regards
Anantha Subramanian Natarajan
