The IESG has approved the following document: - 'YANG Metadata Annotation for Immutable Flag' (draft-ietf-netmod-immutable-flag-14.txt) as Proposed Standard
This document is the product of the Network Modeling Working Group. The IESG contact persons are Mahesh Jethanandani and Mohamed Boucadair. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-netmod-immutable-flag/ Technical Summary This document defines a way to formally document an existing behavior, implemented by servers in production, on the immutability of some system-provided nodes, using a YANG metadata annotation called "immutable" to flag which nodes are immutable. Clients may use "immutable" annotations provided by the server, to know beforehand why certain otherwise valid configuration requests will cause the server to return an error. The immutable flag is descriptive, documenting an existing behavior, not proscriptive, dictating server behaviors. This document updates RFC 8040 and RFC 8526. Working Group Summary Was there anything in the WG process that is worth noting? For example, was there controversy about particular points or were there decisions where the consensus was particularly rough? >From the Shepherd Report: Shepherd: Pretty strong consensus. Several prominent WG members were heavily involved. and Shepherd: The 3GPP submitted https://datatracker.ietf.org/liaison/2072/ hoping that this draft would address their need. This document partially addresses their need without precluding the ability for a future definition to fully address their need. To be clear, this document defines an ability for a server to report what nodes it believes to be immutable, with it being out-of-scope for why/how the server thinks nodes are immutable. 3GPP wants the "why/how" part to be standardized. The liaison response welcomes their participation in the WG. Document Quality Are there existing implementations of the protocol? Have a significant number of vendors indicated their plan to implement the specification? Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? If there was a MIB Doctor, Media Type, or other Expert Review, what was its course (briefly)? In the case of a Media Type Review, on what date was the request posted? >From the Shepherd Report: Shepherd: Appendix C (Existing Implementations) lists known implementations. and Shepherd: There was a YANG Doctor review https://datatracker.ietf.org/doc/review-\ ietf-netmod-immutable-flag-06-yangdoctors-early-andersson-2026-01-05. It was "Ready w/ Issues". The issues were addressed here: https://mailarchive.ietf.org/arch/browse/\ netmod/?q=draft-ietf-netmod-immutable-flag-06%20early%20Yangdoctors%20review Personnel The Document Shepherd for this document is Kent Watsen.
