The way this works is as follows: num packets=4 frequency=30 secs timeout =5 secs 4 echo requests sent every 30 secs. It needs just one echo reply to come back within 5 secs for pass/fail.

The fail criteria is the one which will make everything clear.

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 -----Inline Attachment Follows----- _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
