ASR9000 - IPSLA + Tracking

[Pedro Morais]

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

It seems that you missed some configurations, check above website.

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

Hi Ahmed,

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

Pedro

Hi Ahmed,

I have that package installed:

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

  Active Packages:

    disk0:asr9k-p-4.2.3.CSCud37351-1.0.0

    disk0:asr9k-p-4.2.3.CSCud54093-1.0.0

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

Thanks,

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
