Hello Pipatpong, I remember we had a thread sometime back here about the SLA Monitor feature. Just thought the below excerpt could be useful to you :
ex : Suppose the frequency is 10 seconds, and the num-of-packets is 3 and > the timeout is 1000 ( 1 second ). > The asa sends out 3 pings once every 10 seconds. I configured CPPR on R1 to > only permit 1 echo-request and the 2 were dropped. But the ASA was still > saying that the timeout didn't occur, but i could see the "NumofRTT" field > in "show sla monitor operational-state" go down to 1 ( it was 3 > originally, i.e 3 echo-replies were received) . > But as soon as i dropped all icmp traffic on R1, the ASA immediately showed > that the timeout had occurred. > So as a summary, for the SLA to timeout , all the pings have to timeout, > not just 1. Cheers, TacACK
