IPSLA in XRv9

[Peyman Zadmehr]

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

Can you share the confirmation you were trying to apply and version of xrv9k?

Thanks,

Sam

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

Thank you for the guidance

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