      Network Configuration Protocol (NETCONF) Base Notifications

Abstract

   The Network Configuration Protocol (NETCONF) provides mechanisms to
   manipulate configuration datastores.  However, client applications
   often need to be aware of common events, such as a change in NETCONF
   server capabilities, that may impact management applications.
   Standard mechanisms are needed to support the monitoring of the base
   system events within the NETCONF server.  This document defines a
   YANG module that allows a NETCONF client to receive notifications for
   some common system events.

1.  Introduction

   The NETCONF protocol [RFC6241] provides mechanisms to manipulate
   configuration datastores.  However, client applications often need to
   be aware of common events, such as a change in NETCONF server
   capabilities, that may impact management applications.  Standard
   mechanisms are needed to support the monitoring of the base system
   events within the NETCONF server.  This document defines a YANG
   module [RFC6020] that allows a NETCONF client to receive
   notifications for some common system events.

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   The following terms are defined in [RFC6241]:

   o  client
   o  datastore
   o  protocol operation
   o  server

   The following terms are defined in [RFC5277]:

   o  event
   o  stream
   o  subscription

   The following term is defined in [RFC6020]:

   o  data node

2.  YANG Module for NETCONF Base Notifications

2.1.  Overview

   The YANG module defined within this document specifies a small number
   of event notification messages for use within the 'NETCONF' stream,
   and accessible to clients via the subscription mechanism described in
   [RFC5277].  This module imports data types from the 'ietf-netconf'
   module defined in [RFC6241] and 'ietf-inet-types' module defined in
   [RFC6021].

   These notifications pertain to configuration and monitoring portions
