My goal is to have "track 111" go from up to down in the event of three successive ping losses. I wish the configuration guide had some more simple examples. Anyhow - when I run "show ip sla reaction-trig 1" IOS responds "Reaction trigger not configured" I don't understand why not. And I'm not clear if my end-goal of track going down on 3 losses is met. Any ip sla masters on here??

Hi
Change your react from rtt to timeout
I have simplfied the config a bit from yours so don't copy it (my timers are very low), but mine works
ip sla monitor 1
type echo protocol ipIcmpEcho 192.168.1.2
timeout 1
frequency 3
ip sla monitor reaction-configuration 1 react timeout
ip sla monitor schedule 1 life forever start-time now
Router#sh ip sla monitor statistics
Round trip time (RTT) Index 1
Latest RTT: NoConnection/Busy/Timeout
Latest operation start time: *19:46:33.155 UTC Thu Mar 5 2009
Latest operation return code: Timeout
Number of successes: 1
Number of failures: 20
Operation time to live: Forever
Router#sh ip sla monitor reaction-configuration
Entry number: 1
Reaction: timeout
Threshold Type: Never
Threshold Count: 5
Threshold Count2: 5
Action Type: None

Thank-you. So in your example it appears that an ICMP timeout is defined as 1 second with no reply and then monitor operation runs with a frequency of every 3 seconds. And your reaction config is saying if there are 5 timeouts then then fail. Correct?

Hi
It's 1 ms with no reply.
I think your issue is down to the fact that you where using round trip times rather than timeout (react rtt).
I am allowing 5 timeouts before alerting ( the default), you can amend this with threshold-type .
