Hi Acee,

Yes to support clear CLI the network device would need to maintain 2 sets of counters, I don’t see any other way.

Regards,
Reshad.

Hi Reshad,
So the application is responsible for calculating its own delta counters.  Network devices that support CLI clearing of counters will need to maintain the last cleared value as well for counters that are accessible via YANG model operational state.
Thanks,
Acee

This is regarding the comment I made yesterday during draft-liu-rtgwg-yang-vrrp, Xufeng rightfully stated that this was a question which had to be addressed for all YANG models.

I have attached Juergen’s email on this topic.

Regards,
Reshad.
