ip sla triggering

I am running 12.4(11)XW8 IOS and using "ip sla" ICMP echo and tracking to make routing decisions about Internet traffic. I want there to be at least two failed pings in a row before a FAIL state triggers a change in default route. This seemed more obvious in some earlier versions of ip sla and tracking. How is this accomplished currently? Thank-you.


Re: ip sla triggering

Object tracking of IP SLAs operations allows tracking clients to track the output from IP SLAs objects and use the provided information to trigger an action.

Cisco IOS IP SLAs is a network performance measurement and diagnostics tool that uses active monitoring. Active monitoring is the generation of traffic in a reliable and predictable manner to measure network performance. Cisco IOS software uses IP SLAs to collect real-time metrics such as response time, network resource availability, application performance, jitter (interpacket delay variance), connect time, throughput, and packet loss.

Re: ip sla triggering

Thanks for the reply. What I am trying to find out is how to fine tune an ICMP echo type IP SLA. That is - I want it to fail more than once to give a failed reading. Thoughts on that?

Re: ip sla triggering

There are options to configure triggers for "an event only after a violation occurs a specified number of times consecutively. For example, the consecutive violation type could be used to configure an action to occur after a timeout occurs 5 times in a row, or when the round-trip-time exceeds the upper threshold value 5 times in a row. "


I must say I have no experience with it myself.

HTH, Thomas
