Hi all !
I'm an intern in a network company, in France. I'm working on IP SLAs operations on a 2821 router.
I've configured the ICMP Path Echo operation in a lab as following :
(on R1, IOS c2800nm-advipservicesk9-mz.151-2.T2)
ip sla 5
path-echo 192.168.2.2 source-ip 192.168.1.254
frequency 30
ip sla schedule 5 start-time now life 150
It works. But I can't find the command which will give the value of RTT for each hop.
I've tried this :
R1-2800#sh ip sla statistics 5
IPSLAs Latest Operation Statistics
IPSLA operation id: 5
Latest RTT: 1 milliseconds
Latest operation start time: 15:43:19.379 GMT+2 Mon Apr 23 2012
Latest operation return code: OK
Operation time to live: 145 sec
Then, this :
R1-2800#sh ip sla statistics aggregated 5 details
IPSLAs aggregated statistics
IPSLA operation id: 5
Start Time Index: 15:43:19.383 GMT+2 Mon Apr 23 2012

Well, I know that I can find the value with the value of "Sum of Latency", by subtracting the actual value from the one get just before.
It would be very usefull to know directly the RTT value for each hop. Does any command give it ?
Thanks.
