Hello
I would like to track icmp jitter for end host. I verified in documentation that it can be any host as a destination. But i got error on this operation:
Latest RTT: NoConnection/Busy/Timeout
I verified that there is no firewall between the source and destination and icmp timestamp request works when done manually:
r01#ping

Try "icmp-echo" instead "icmp-jitter".
The icmp-jitter needs a responder on the other side. You can use icmp-jitter between two routers, one with ip sla operation, and the other one with the ip sla responder.
ip sla 1 icmp-echo 192.168.17.1 source-ip 192.168.17.2 timeout 1000 frequency 30 ip sla schedule 1 life forever start-time now

Hi Jorge
According to Cisco documentation icmp-jitter should work on any IP Device.
I have a similar issue.
1. I can run icmp-jitter successfully to non cisco routers
2. it fails to run to a generic ip device.
