IP SLA Operation Down

Question

I have two Cisco Routers completely identical minus variations to addressing in the config.

Both have the same IPSLA configs applied with a custom owner so then we cause IP SLA 3.5.1 to monitor existing operations.

Everything so far so good.  I apply IPSLA configs and then discover.  Both routers return 22 operations.  Verify from CLI that each one is returning stats.

In the Orion web console all operations on Router A are good to go.  Router B only shows one operation up.  the others are down.

For Router B I can verify good stats on the CLI.  For Router B I can drill in on an operation and see the same ICMP Jitter hops that are represented in CLI.

The data looks good but Orion/IP SLA Manager report the operation down.  Any ideas why?  what is the dependancy that causes an IPSLA operation to report down.  The Admin guide doesn't really say what it looks for to determine if operation is up or down.  It discovers and is tracking data.  Cant understand why this router reports the operation down.  I have deleted and reapplied.  seems specific to this router.  I just want to know what the operation is looking for to determine status so I can fix it.

So, it's reporting Operation Timeout in IP SLA Manager and router console as well, right? This can be caused by missing time synchronization between the device and operation target device. Could you check if the difference between working operations and operation with timeout issue isn't in missing NTR/SNTR synchronization? Issue could be caused by wrong time on source or target device. This could be the reason, why one operation works and others not.

1.        Its ICMP Path Jitter

2.       Status message is Operation Timed Out

The Status Message doesn’t make sense.  Orion is displaying hop counts.

1) Is it ICMP Path Jitter operation we're talking about? It's important to know for me to determine possible cause. Results of Path operations are polled by CLI and results of other operation types are polled by SNMP.

2) What's the status message of operations with Down status?
