Hello!
I'm sure this is a simple question, but no matter how many documents I read over, I can't seem to get a clear answer. I'm just trying to setup a simple SLA failover. I have the same situation on both my L3 switches as well as FTD firewalls. SLA options are for threshold, timeout, and frequency. I somewhat understand how each of those items work, but here's my problem. Using those settings, whatever the frequency I set, the SLA still fails whenever the test fails. I don't want a single failure to flap the interface. I want to do something like test with a frequency of 5 seconds and if it fails 3 times in a row, THEN it will failover.
Is that possible? What is standard in the industry when you have two ISPs?
Thanks,
Andy

You need to post the confioguraiton example you using :
here is example :
ip sla 1
icmp-echo x.x.x.x .1 source-interface interface x/x
frequency 30
ip sla schedule 1 life forever start-time now
track 1 ip sla 1 reachability
delay down 40 up 10
Ping every 30 seconds, track delay 40 so get 2 ping failures before say it is down.
there are good example for dual ISP :

Thank you! I didn't know about the delay part.
