Abstract
摘要
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).
此备忘录定义了管理信息库（MIB）的一部分，用于Internet社区中的网络管理协议。特别是，它描述了用于扩展实体MIB（RFC 2737）的托管对象，以提供对物理传感器相关信息的通用访问，这些信息通常存在于网络设备中（例如机箱温度、风扇转速、电源电压）。

有关描述当前互联网标准管理框架的文件的详细概述，请参阅RFC 3410[RFC3410]第7节。
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].
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB对象通常通过简单网络管理协议（SNMP）进行访问。MIB中的对象是使用管理信息结构（SMI）中定义的机制定义的。本备忘录规定了符合SMIv2的MIB模块，如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。
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.
需要一种标准化的方法来获取与网络设备中常见的物理传感器相关的信息。对于任何类型的传感器，应以一致的方式表示传感器的当前值、当前操作状态以及与传感器相关的数据单位精度等信息。
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.
物理传感器用entPhysicalEntry和entPhysicalClass值“传感器（8）”表示在实体MIB中。ENTITY-SENSOR-MIB模块（在本文档中定义）中提供的信息为表示物理传感器的条目定义了entPhysicalTable的稀疏扩充。
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]
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照BCP 14、RFC 2119中的说明进行解释。[RFC2119]
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 representing a physical sensor. Therefore, implementation of the entityPhysicalGroup is required for agents that implement the Entity Sensor MIB.
本文档中定义的MIB对象为实体MIB中的entPhysicalTable提供了稀疏扩充，用于关联的entPhysicalClass对象等于“传感器（8）”的条目。对于表示物理传感器的每个entPhysicalEntry，代理应维护具有相同entPhysicalIndex值的EntPhysicalSensorEntry。因此，实现实体传感器MIB的代理需要实现entityPhysicalGroup。
There are no specialized sensor value thresholding mechanisms defined in this MIB module. Instead, it is recommended that a generalized thresholding MIB, such as the mechanisms defined by the Alarm and Events groups of the Remote Network Monitoring MIB [RFC2819], be used for this purpose.
此MIB模块中没有定义专门的传感器值阈值机制。相反，建议为此目的使用通用阈值MIB，如远程网络监控MIB[RFC2819]的报警和事件组定义的机制。
The Entity Sensor MIB contains a single group called the entitySensorValueGroup, which allows objects to convey the current value and status of a physical sensor.
实体传感器MIB包含一个名为entitySensorValueGroup的组，该组允许对象传递物理传感器的当前值和状态。
The entitySensorValueGroup contains a single table, called the entPhySensorTable, which provides a small number of read-only objects:
entitySensorValueGroup包含一个名为entPhySensorTable的表，该表提供少量只读对象：
entPhySensorType This object identifies the type of data units associated with the sensor value.
entPhySensorType此对象标识与传感器值关联的数据单元类型。
entPhySensorScale This object identifies the (power of 10) scaling factor associated with the sensor value.
entPhySensorScale此对象标识与传感器值关联的（10的幂）比例因子。
entPhySensorPrecision This object identifies the number of decimal places of precision associated with the sensor value.
entPhySensorPrecision此对象标识与传感器值关联的精度小数位数。
entPhySensorValue This object identifies the current value of the sensor.
entPhySensorValue此对象标识传感器的当前值。
entPhySensorOperStatus This object identifies the current operational status of the sensor (as it's known to the agent).
entPhySensorOperStatus此对象标识传感器的当前操作状态（代理已知）。
entPhySensorUnitsDisplay This object provides a textual description of the data units represented by the entPhySensorType and entPhySensorScale objects.
EntphySensorUnits显示此对象提供由entPhySensorType和entPhySensorScale对象表示的数据单元的文本描述。
entPhySensorValueTimeStamp The object identifies the value of sysUpTime at the time the agent last updated the information in the entry. This object is only relevant if the agent uses a polling implementation strategy, (i.e., the associated entPhySensorValueUpdateRate object is greater than zero).
entPhySensorValueTimeStamp对象标识代理上次更新条目中信息时的sysUpTime值。仅当代理使用轮询实现策略时（即关联的entPhySensorValueUpdateRate对象大于零），此对象才相关。
entPhySensorValueUpdateRate This object indicates the nature of the agent implementation of the entPhySensorEntry, and contains the (possibly estimated) number of milliseconds that elapse between polling updates of the information in the associated entry. The value zero indicates that the agent always return current data for the entry (as opposed to the data as it was at the last polling interval).
entPhySensorValueUpdateRate此对象指示entPhySensorEntry的代理实现的性质，并包含关联项中信息的轮询更新之间经过的（可能估计的）毫秒数。值0表示代理始终返回条目的当前数据（与上次轮询间隔时的数据相反）。

If an object of this type contains a value in the range -8 to -1, it represents the number of accurate digits in the associated EntitySensorValue fixed-point number.
如果此类型的对象包含范围为-8到-1的值，则它表示关联EntitySensorValue定点数中的精确位数。

There is one managed object in this MIB that may contain sensitive information. This is:
此MIB中有一个托管对象可能包含敏感信息。这是：
entPhySensorValue
内翻值
This object may expose the values of particular physical sensors for a device.
此对象可能会公开设备的特定物理传感器的值。
SNMPv1 by itself is not a secure environment. Even if the network itself is secure (for example by using IPSec), there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB.
SNMPv1本身不是一个安全的环境。即使网络本身是安全的（例如通过使用IPSec），也无法控制安全网络上的谁可以访问和获取/设置（读取/更改/创建/删除）此MIB中的对象。
It is recommended that the implementors consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model STD 62, RFC 3414 [RFC3414] and the View-based Access Control Model STD 62, RFC 3415 [RFC3415] is recommended.
建议执行者考虑SNMPv3框架提供的安全特性。具体而言，建议使用基于用户的安全模型STD 62、RFC 3414[RFC3414]和基于视图的访问控制模型STD 62、RFC 3415[RFC3415]。
It is then a customer/user responsibility to ensure that the SNMP entity giving access to an instance of this MIB, is properly configured to give access to only the objects, and those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
然后，客户/用户有责任确保授予对此MIB实例访问权限的SNMP实体正确配置为仅授予对对象的访问权限，以及具有确实获取或设置（更改/创建/删除）对象的合法权限的主体（用户）。
