I have reviewed draft-ietf-ippm-ioam-yang-11 as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review.  Document editors and WG chairs should treat these comments just like any other last call comments.

   "In-situ Operations, Administration, and Maintenance (IOAM) is an
   example of an on-path hybrid measurement method.  IOAM defines a
   method to produce operational and telemetry information that may be
   exported using the in-band or out-of-band method.  RFC9197 and
   RFC9326 discuss the data fields and associated data types for IOAM.
   This document defines a YANG module for the configuration of IOAM
   functions."

My overall view of the document is 'Ready' for publication.

** Technical **

No.

** Editorial **

No.


I do not see any special operational or network management related issue. I just have some clarification questions:
1. I do not see any configuration on data export, especially for the direct export type. May I ask your consideration?
2. I see only the ingress node need to configure the max-length check. May i ask what about the subsequent nodes?
