IP SLA icmp jitter operation

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.
