Hi, all,

There is a comment received during the WGLC of this draft, which is about the copy scope of "resolve-system" parameter, i.e., should the server only auto-copy the minimum to make configuration valid or the entire contents of a referenced list entry?

Like any value provided by the server that is not the schema default value needs to be copied into <running> (https://www.ietf.org/archive/id/draft-ietf-netmod-system-config-06.html#section-6) should the server also copy other system nodes that is not provided in <running> when triggered by "resolve-system" parameter? Personally I don’t think this is needed for <system>-aware clients which can always read <system> to discover system-provided values, and read <intended> to get a merged view of <system> and <running>. This is mainly the consideration for non-NMDA clients that has no way to discover system configuration and thus any data missing from <running> will result in the client having the wrong impression. On the other hand, copy-all might be easier to implement for the server than to calculate the minimum.

Any thoughts? Should this be addressed in this document? 

Best Regards,
Qiufang //co-author

Internet-Draft draft-ietf-netmod-system-config-06.txt is now available. It is a work item of the Network Modeling (NETMOD) WG of the IETF.

   Title:   System-defined Configuration
   Authors: Qiufang Ma
            Qin Wu
            Chong Feng
   Name:    draft-ietf-netmod-system-config-06.txt
   Pages:   39
   Dates:   2024-05-31

Abstract:

   This document defines how a management client and server handle YANG-
   modeled configuration data that is instantiated by the server itself.
   The system-defined configuration can be referenced (e.g., leafref) by
   configuration explicitly created by a client.

   The Network Management Datastore Architecture (NMDA) defined in RFC
   8342 is updated with a read-only conventional configuration datastore
   called "system" to expose system-defined configuration.

   This document updates RFC 8342, RFC 6241, RFC 8526 and RFC 8040.
