               Entity Sensor Management Information Base

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it describes managed objects for extending the Entity
   MIB (RFC 2737) to provide generalized access to information related
   to physical sensors, which are often found in networking equipment
   (such as chassis temperature, fan RPM, power supply voltage).

1. The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI).  This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580].

2.  Overview

   There is a need for a standardized way of obtaining information
   related to the physical sensors which are commonly found in
   networking equipment.  Information such as the current value of the
   sensor, the current operational status, and the data units precision
   associated with the sensor, should be represented in a consistent
   manner for any type of sensor.

   Physical sensors are represented in the Entity MIB with
   entPhysicalEntry and an entPhysicalClass value of 'sensor(8)'.  The
   information provided in the ENTITY-SENSOR-MIB module (defined in this
   document) defines a sparse augmentation of the entPhysicalTable, for
   entries which represent physical sensors.

2.1.  Terms

   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 BCP 14, RFC 2119.
   [RFC2119]

2.2.  Relationship to the Entity MIB

   The MIB objects defined in this document provide a sparse
   augmentation to the entPhysicalTable in the Entity MIB, for entries
   in which the associated entPhysicalClass object is equal to
   'sensor(8)'.  An agent is expected to maintain an entPhySensorEntry
   with the same entPhysicalIndex value for each entPhysicalEntry
