Title: Guidelines for Characterizing "OAM"
Reviewer: Tim Chown
Review result: Has Nits

Hi,

I have been selected as the Operational Directorate (opsdir) reviewer for this
Internet-Draft.

The Operational Directorate reviews all operational and management-related
Internet-Drafts to ensure alignment with operational best practices and that
adequate operational considerations are covered.

A complete set of _"Guidelines for Considering Operations and Management in
IETF Specifications"_ can be found at
https://datatracker.ietf.org/doc/draft-opsarea-rfc5706bis/.

While these comments are primarily for the Operations and Management Area
Directors (Ops ADs), the authors should consider them alongside other feedback
received.

## Summary

Choose one:

- Has Nits: This document is basically ready for publication but has nits that
should be considered prior to publication.

## General Operational Comments Alignment with RFC 5706bis

This is the third time I've reviewed this draft. I think recent iterations have
given the document a good focus.

It serves a very useful purpose in clarifying the use of OAM terminology, and
its qualifiers, especially of "in-band" and "out-of-band" which it recommends
against using.

## Major Issues

There are no remaining major issues in the draft.

## Minor Issues

There are no minor issues.

## Nits

I like that at the start of section 3 the document states "This document
recommends avoiding the terms "in-band" and "out-of-band" when referring to
OAM. Instead, it encourages the use of more fine-grained and descriptive
terminology."

I think these two sentences, at the very least the first, should be added to
the abstract (maybe expanding the second paragraph) and to the text in Section
2 (maybe at the end of the penultimate paragraph).  I suspect the focus of the
draft has moved over time and the abstract not been updated to reflect that.
