IPv6 Netflow support on PWHE interface

[Josef Baloun]

Hello engineers,

we found an issue with IPv6 Netflow over Pseudowire Headend on ASR-9001-S running version 6.3.3 after upgrade from 6.1.4. Configuration running in 6.1.4 is not allowed to be committed in 6.3.3 with the error message:

interface PW-Ether1
 flow ipv6 monitor IPv6FLOW sampler SAMPLER ingress

I did not found information it would not be supported. Do you have any information or experience?

Hi,

It looks like it is not supported. This will need a new feature request.
