Hi - interesting thanks, I can see nothing at 1.3.6.1.4.1.9.9.572 so as far as I can tell there is no support for CISCO-RTTMON-IP-EXT-MIB at all on the platform.
I'll poke the TAC guy who's currently trying to work out why having more than 2 IPSLAs kills the chassis...
Cheers for your help!

Hi Mike,
Thanks for looking, I can confirm we are at r8715 but the testing on one of our Lab 9Ks indicates that it doesn't show the IPv6 data, unfortunately. I've attached the relevant debug just in case you do get a chance to look.
I notice that it only lists the rttMonLatestRttOperAddress for the V4 entries, so I'm assuming this is where the data 'should' have been for the V6 targets. Unless there's a separate OID for V6 information that you have found elsewhere?
nono, V6 targets should be in same table/list, but with empty rttMonEchoAdminTargetAddress:
CISCO-RTTMON-MIB::rttMonEchoAdminTargetAddress.66 = ""
V6 target addresses displayed in other table:
CISCO-RTTMON-IP-EXT-MIB::crttMonIPEchoAdminTargetAddress.66 = Hex-STRING: 2A 02 04 08 77 22 00 41 00 00 00 00 00 00 01 50
This is just IOS XR issue, I think.
(IPSLAs starting 25x are the V6 ones)
All the best,

Just tested IPv6 SLA target (on classic IOS device).
All (possible) v6 targets already discovered, but not detected IP addresses for v6. This fixed in r8715.
Not know about IOS XR, but if device report IPv6 SLA in SNMP - it should be visible in Observium too.

Hi - thanks for that, I'm unsurprised by Cisco...
In fact - the additional 4 additional IPSLAs we added caused a catastrophic ASR chassis lockup a few hours later.
Turns out you cannot have more than 2 IPSLAs running on a Tuesday, or some other Cisco rubbish.
See https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvd76303/ if you are running IOS-XR between 5.3.3 and 6.2.2 and are considering adding IPSLAs. Even if you have some already, it's very easy to trigger this by making changes to them! It was only a 9001 but it took out 4x10G of transit for us - even the serial console didn't work when it locked up so we had to power cycle the whole damn thing....

That's IOS issue, snmp doesn't report IPv6 addreses for SLA metrics. At least that was on classic IOS, i didn't tried on IOS-XR.

Hi all,
We have a requirement for some IPv6 IPSLA instances on an ASR9k.
Can't say this has ever come up before, but anyway, it appears that the IPv6 target IPs don't show up (thousand words below):
Is this a known issue (ie. Cisco failing to send it) or did we find a bug?
Interestingly, the actual 'result' latency data is all there (and correct) but somewhat difficult to comprehend without the target IP :)
Cheers!
