IPSLA in XRv9

HI 

Whenever I try to configure IPSLA in XRv9 I encountered an error about this feature has no resources and cannot be enabled.

Is there any workaround for this? Is it supported in XRv9?

Thank you

I believe only UDP echo is supported not ICMP echo as per the trace below.

That is correct, in xrv9k only UDP probes are supported, not ICMP.
