                   draft-ietf-netconf-nmda-netconf-00

Abstract

   The "Network Management Datastore Architecture" (NMDA) improves on
   NETCONF by adding new features to give more accurate handling of
   configuration and operational data.  These include ability to inspect
   the current operational values of configuration data, allowing
   clients to use identical paths for retrieving the configured values
   and the operational values.  These new features require additional
   operations in network management applications such as NETCONF.  This
   draft details those new operations.

1.  Introduction

   This document provides a YANG model that adds NETCONF ([RFC6241])
   support for the "Network Management Datastore Architecture" (NMDA)
   [I-D.ietf-netmod-revised-datastores].  NMDA defines a framework for
   datastores, a fundamental concept binding network management data
   models to network management protocols, enabling data models to be
   written in a network management protocol agnostic way.  NETCONF
   operations currently refer to the datastores defined in the original
   model, so new operations are required to allow references to the new
   datastores.

   Operations like <copy-config>, <lock> and <unlock> are augmented to
