                  draft-vallin-netmod-alarm-module-02

Abstract

   This document defines a YANG module for alarm management.  It
   includes functions for alarm list management, alarm shelving and
   notifications to inform management systems.  There are also RPCs to
   manage the operator state of an alarm and administrative alarm
   procedures.  The module carefully maps to relevant alarm standards.
