ASR9000 - IPSLA + Tracking

Hi,

I'm trying to install a static route when an IP address is not reachable, using IPSLA (ICMP echo) + tracking. I've found all the documentation  and know how to configure it, however I'm strugling to configure the IPSLA operation. For some reason it doesn't start, and returns the following message:

RP/0/RSP0/CPU0:A9K-AGR1#sh ipsla statistics 1000

Tue Jul 23 11:25:21.203 WEST

No information available. Specified operation is not configured or operation may have aged out

The configuration is pretty straightforward and I believe it is correct:

ipsla

operation 1000

  type icmp echo

   vrf iub

   source address 10.187.253.137

   destination address 10.187.253.138

   frequency 5

  !

!

!

ipsla

schedule operation 1000

  start-time now

  life forever

!

!

Could anyone help me find out what am I doing wrong?

Thanks.

Cheers,

Pedro

Hi Hu,

I'm aware of the tracking configuration. My issue is with the IPLSA probe that doesn't start.

Thanks.

Cheers,

Hello Pedro,

There should be a problem with configuration vrf or OID typos, or the XR Version you are running doesnt support SLA.

You can verify the process status for ipsla using admin show proc | in sla

I have tried the above configuration you have - on IOX4.2.3

RP/0/RSP0/CPU0:EQUINOX-A9k#show run ipsla

Mon Jul 29 05:35:31.670 UTC

ipsla

operation 1000

  type icmp echo

   vrf A

   source address 192.168.1.7

   destination address 192.168.1.1

   frequency 5

  !

!

schedule operation 1000

  start-time now

  life forever

It shows no issues.

Hi Ahmed,

That's strange, I'm also running 4.2.3. Could you share the SMUs you have installed?

Re: ASR9000 - IPSLA + Tracking

Hi Ahmed,

I have that package installed:

RP/0/RSP0/CPU0:ASR-LAB01#sh install active summary

Tue Jul 30 10:34:29.775 WEST

  Active Packages:

    disk0:asr9k-p-4.2.3.CSCud37351-1.0.0

    disk0:asr9k-p-4.2.3.CSCud29892-1.0.0

    disk0:asr9k-mini-p-4.2.3

    disk0:asr9k-doc-p-4.2.3

    disk0:asr9k-p-4.2.3.CSCub22596-1.0.0

    disk0:asr9k-k9sec-p-4.2.3

    disk0:asr9k-p-4.2.3.CSCud54093-1.0.0

I strongly believe that this might be a SMU related issue.

Thanks,

Re: ASR9000 - IPSLA + Tracking

Hello Pedro,

On my lab , I dont have any SMUs installed- I still suspect the configuration.

Otherwise the only difference is the Card Type , I see yours are Trident cards, however it should be supported unless there is a missing SMU that solves a certain issue on that.

Thank You
