IP SLA ICMP Path Echo - Results in CLI

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 :

2_2.png

(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

Path Index: 1

Hop in Path Index: 1

Type of operation: path-echo

Number of successes: 5

Number of failures: 0

Failed Operations due to over threshold: 0

Failed Operations due to Disconnect/TimeOut/Busy/No Connection: 0/0/0/0

Failed Operations due to Internal/Sequence/Verify Error: 0/0/0

Target Address 10.0.0.2

Distribution Statistics:

Bucket Range: 0-19 ms

Avg. Latency: 1 ms

Percent of Total Completions for this Range: 100 %

Number of Completions/Sum of Latency: 5/5

Sum of RTT squared low 32 Bits/Sum of RTT squared high 32 Bits: 5/0

Operations completed over threshold: 0


Start Time Index: 15:43:19.383 GMT+2 Mon Apr 23 2012

Path Index: 1

Hop in Path Index: 2

Type of operation: path-echo

Number of successes: 5

Number of failures: 0

Failed Operations due to over threshold: 0

Failed Operations due to Disconnect/TimeOut/Busy/No Connection: 0/0/0/0

Failed Operations due to Internal/Sequence/Verify Error: 0/0/0

Target Address 192.168.2.2

Distribution Statistics:

Bucket Range: 0-19 ms

Avg. Latency: 1 ms

Percent of Total Completions for this Range: 100 %

Number of Completions/Sum of Latency: 5/5

Sum of RTT squared low 32 Bits/Sum of RTT squared high 32 Bits: 5/0

Operations completed over threshold: 0

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.

There is no command which will show you RTT for each hop. You need to configure  several probes from the source - one for each hop in the path.
