Kent,

Hi Jan, you attended the Interim on Jan 23, and didn’t object to the Minutes [1] that say:

     The consensus in the room was a new "Option 4" - i.e., this
     document doesn't say anything at all about the validity of
     <running>.  That is, fully rely on existing 7950 and 8342
     statements.  This leaves it up to interpretation.

Has something changed since then?

[1] https://datatracker.ietf.org/doc/minutes-interim-2024-netmod-01-202401231400/

Thanks for keeping me honest :-) Nothing has changed, and if everyone agrees that 7950 and 8342 language prevail (i.e. running always valid as well as intended always valid), I'm probably ok. I wasn't sure that was the case? But if we all agree with this, maybe stating just that wouldn't be a bad thing? Just so that this is perfectly clear now and in the future.

I'm not against discussing changes in this area, as long as the fundamental values of YANG are preserved and our mechanisms are clearly defined.

Best Regards,
/jan

Qiufang,

I'm sorry to say I'm strongly against WGLC at this time because of point #2 below.

One of the great contributions to network automation that YANG has brought is that clients now have a fair chance at computing a desired configuration change for a network element. Maybe we need to develop a more elaborate model for configuration consistency relative today's "The running configuration datastore MUST always be valid", but have I trouble with us stirring up multiple interpretations and then staying silent. That's not the way to build interoperability.

IMO we need to sort out what the rules are before we come close to WGLC, or else the grief outweighs the gain.

Best Regards,

Hi, chairs,

For system-config draft (https://datatracker.ietf.org/doc/draft-ietf-netmod-system-config/), the authors have submitted a new version to reflect the outcome of the interim, the main updates are following:
1.      Address the "origin" issue
a.       The current document explicitly states that system configuration copied from <system> into <running> have its origin value being reported as "intended" and update the examples accordingly
b.      Also, update the definition of "intended" origin identity in 8342 to allow a subset of configuration in <intended> to use "system" as origin value
c.       The current document states data migration is out-of-scope except that gives a couple of implementation examples in section 4.2 (please feel free to propose text if you have better suggestion)
2.      validity of <running> alone
a.       The current document is silent on this point. Related statements which requires referenced system nodes must be copied into <running> are removed.
3.      Other updates
a.       Usage examples refinement, e.g., fix validation errors, remove redundancy for conciseness

There is currently no open issues, thus the authors believe this draft is ready for WGLC, but this might be worth a broad review on the mailing list.

Best Regards,
Qiufang
