Re: [Rtg-yang-coord] Clearing all stats in a container

["Susan Hares" <[e-mail]>]

Juergen:

Thank you for this advice.  If you have time (before the Draft deadline) to
look at the grouping of the statistics within the I2RS RIB, and provide us
with advice on the groupings - it would be helpful.

Any other comments on the draft would aid the authors and the I2RS WG.  The
authors would like comments sent to them until the IETF draft deadline.
After that, I suspect the I2RS mail is best.

Hi,

it was generally found useful when we did the interfaces and ip YANG models
to properly separate config data from state data. And this is not just
counters, it could include other things where operational state can be
different from the configured state.

is to be able to perform bulk operations on them. Of course, as Juergen
pointed out, clearing stats may not be one of them. But if you wanted to say
<get> all the stats on a particular module, you would do a <get> on the
container i.e. statistics in this example, and you would have all the stats.
