Any success will continue to allow the sla to be valid. That should answer the rest of your questions as well.

Here's what i found Frequency -> Once in how many seconds should the ASA try to reach the destination to verify the SLA. If the frequency is configured as 10 seconds, then once in ten seconds the ASA will try and ping the destination. num-packets -> "how many" echo-requests are sent from the ASA during each ping attempt (once every frequency interval) . Ex : Suppose the num-of packets is 3 and the frequency is 10 seconds. Then, at the end of 10 seconds, the ASA will send 3 echo-requests continuously to the destination and wait for the response from the destination. timeout -> It defines how much time the ASA will wait for the echo-replies for each of the pings that it sends / per frequency time-period. Now a couple of questions come into my mind which are similar to yours 1) Suppose the num-of-packets is set to 3, frequency is 10 seconds and the timeout is set to 1000 ( 1 second ), and the ASA replies prompt echo-replies for the first 2 ICMP echo-replies and the 3rd echo-reply comes in after 2 seconds, what happens to the SLA? Does it show it as down? 2) What's the purpose of sending multiple pings at each interval period? :) Cheers, TacACK
