                 A YANG Data Model for Alarm Management

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
   operations to manage the operator state of an alarm and
   administrative alarm procedures.  The module carefully maps to
   relevant alarm standards.
