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).
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。
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].
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。
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”、“必需”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照BCP 14、RFC 2119[RFC2119]中的说明进行解释。
For the purpose of management, it is necessary to access Managed Objects (MOs). The SNMP framework provides a mechanism for naming and describing managed objects. These objects are accessed via a virtual information store termed a Management Information Base (MIB). MIBs have been defined by equipment, protocol, and application developers to provide management access to the managed entities. We will call the MOs defined in these MIBs simple MOs (SMO). Management applications will access one or more instances of these SMOs, one or more times, to monitor the target entity.
为了进行管理，有必要访问托管对象（MOs）。SNMP框架提供了一种命名和描述托管对象的机制。这些对象通过称为管理信息库（MIB）的虚拟信息存储访问。MIB由设备、协议和应用程序开发人员定义，以提供对受管实体的管理访问。我们将这些MIB中定义的MOs称为简单MOs（SMO）。管理应用程序将访问这些SMO的一个或多个实例一次或多次，以监视目标实体。
There is a cost associated with accessing MOs. The cost is the network bandwidth and the packet header processing overhead at the command generator (manager) and the command responder (agent). This cost constrains the number of MO instances that can be polled and the interval at which polling can be carried out.
访问MOs会带来成本。成本是网络带宽和命令生成器（管理器）和命令响应器（代理）的数据包头处理开销。此成本限制了可以轮询的MO实例的数量以及可以执行轮询的间隔。
The overhead reduction can be carried out by reducing the number of query-response packets. This will reduce the packet processing overhead, and to some extent, the bandwidth.
可以通过减少响应包的数量来减少开销。这将减少数据包处理开销，并在一定程度上减少带宽。
The payloads in a typical SNMP "get" packet and the corresponding response are as shown in Figure 1. In this example, polling is carried out for 'n' Managed Object instances OID1, OID2, ..., OIDn. It is obvious that a substantial amount of the payload in an SNMP packet consists of the OIDs.
典型SNMP“get”数据包中的有效负载和相应的响应如图1所示。在此示例中，对“n”个托管对象实例OID1、OID2、…、OIDn执行轮询。很明显，SNMP数据包中的大量有效负载由OID组成。
In this document, a mechanism of MO aggregation for payload compression is defined. The idea is simple: we introduce the concept of an Aggregate MO (AgMO). An AgMO is just another MO as far as the SNMP protocol is concerned. No new protocol operations will be required to handle these MOs. As in the case of any other MO, it requires additional instrumentation at the command responder (agent) and at the (command generator) manager. In this mechanism, the user defines an Aggregate MO (AgMO) corresponding to one or more (predefined) MO instances. Semantically, the value of an AgMO instance will be equivalent to the concatenation of the values of the corresponding MO instances. The order of the concatenation will be determined by the order in which the MO instances are specified in the AgMO definition. With the definitions done, the user can, as and when the necessity arises, do an SNMP 'get' on instances of the AgMO to fetch the value of the constituent MO instances. There is substantial savings on bandwidth, as only one instance object identifier is carried in the request and the response. In the normal case, instance object identifiers for each of the constituent MO instances would be carried in the requests and the responses. This is the basic concept of Aggregate Managed Objects. For every AgMO, an ErrorStatus Managed Object is defined. This MO indicates errors, if any, that have been encountered while fetching the values of the constituent MO instances. The error indication is comprised of the index of the MO instance and the corresponding error. If there are no errors, the ErrorStatus Managed Object instance will have a null value. This is the basic concept of Aggregate Managed Objects.
在本文中，定义了用于有效负载压缩的MO聚合机制。想法很简单：我们引入了聚合MO（AgMO）的概念。就SNMP协议而言，AgMO只是另一个MO。处理这些MOs不需要新的协议操作。与任何其他MO一样，它需要在命令响应程序（代理）和（命令生成器）管理器上进行额外的检测。在这种机制中，用户定义了一个与一个或多个（预定义的）MO实例相对应的聚合MO（AgMO）。从语义上讲，AgMO实例的值将等效于相应MO实例的值的串联。连接顺序将由AgMO定义中指定MO实例的顺序决定。定义完成后，用户可以在必要时对AgMO的实例执行SNMP“get”，以获取组成MO实例的值。由于请求和响应中只携带了一个实例对象标识符，因此在带宽上节省了大量资源。在正常情况下，请求和响应中将携带每个组成MO实例的实例对象标识符。这是聚合托管对象的基本概念。对于每个AgMO，都定义了一个ErrorStatus管理对象。此MO表示在获取组成MO实例的值时遇到的错误（如果有）。错误指示由MO实例的索引和相应的错误组成。如果没有错误，ErrorStatus托管对象实例将具有空值。这是聚合托管对象的基本概念。
The concepts are explained in Figure 2. An aggregate managed object, AgMOx, has been defined for the MO instances MOI1, ... MOIn. The value of an instance of AgMOx will be a concatenation of the values of MOI1, ... MOIn, in that order.
图2中解释了这些概念。已为MO实例MOI1…定义了聚合托管对象AgMOx。。。莫因。AgMOx实例的值将是MOI1。。。莫恩，按顺序。

As a further refinement of the AgMO, we introduce the Time-Based Aggregated Managed Object (TAgMO). The TAgMO is an MO that represents the values of a user-specified MO instance sampled at user-specified intervals for a user-specified number of times. In this case, the user defines a TAgMO by specifying the MO instance that needs to be sampled, the sampling interval, and the desired number of samples that will be included in one TAgMO. The value of a TAgMO instance will include the timestamp (sysUpTime) at which the first sample was taken. The start time is not specified when the TAgMO is defined. Implementations may choose to align the start time with the appropriate time boundaries (e.g., seconds, minutes, hours). With the definitions, the user can do an SNMP "get" on an instance of the TAgMO to fetch the values of the constituent MO instance sampled at the specified intervals. This is the concept of Time-Based aggregation.
作为AgMO的进一步完善，我们引入了基于时间的聚合托管对象（TAgMO）。TAgMO是一个MO，表示用户指定的MO实例的值，该实例以用户指定的间隔采样用户指定的次数。在这种情况下，用户通过指定需要采样的MO实例、采样间隔以及将包含在一个TAgMO中的所需样本数来定义TAgMO。TAgMO实例的值将包括获取第一个样本的时间戳（sysUpTime）。定义TAgMO时未指定开始时间。实施可以选择将开始时间与适当的时间界限（例如秒、分钟、小时）对齐。使用这些定义，用户可以对TAgMO的实例执行SNMP“get”，以获取按指定间隔采样的组成MO实例的值。这就是基于时间的聚合的概念。

Figure 4. Time-Based aggregation
图4。基于时间的聚合
The TAgMO instance is a "bucket" of data representing the value of the corresponding MO instance sampled at 'i' microsecond intervals, 'n' times (i.e., over a 'n' X 'i' microsecond window). The TAgMO instance value gets updated at 'n' X 'i' microsecond intervals.
TAgMO实例是一个数据“桶”，表示以“i”微秒间隔、“n”次（即，在“n”X“i”微秒窗口内）采样的对应MO实例的值。TAgMO实例值以“n”X“i”微秒的间隔更新。
The general requirements of managed object aggregation are as follows:
托管对象聚合的一般要求如下：
o It should lead to fewer packets. o It should lead to less bandwidth consumption. o It should not lead to loss of information.
o 这将导致更少的数据包。o它应该减少带宽消耗。o不应导致信息丢失。
In the case of Time-Based aggregation, there will be a delay involved in getting the actual data. The minimum delay in this case will be the duration of the aggregation.
在基于时间的聚合的情况下，获取实际数据会有延迟。这种情况下的最小延迟是聚合的持续时间。
The manager application is expected to configure AgMOs (Aggregate MOs) and TAgMOs (Time-Based Aggregate MOs) with care so that the response size is not too large. In case the resultant response size is larger than the maximum acceptable message size of the originator or larger than the local maximum message size, then the error-status field will be set to "tooBig".
manager应用程序需要小心地配置AgMOs（聚合MOs）和TAgMOs（基于时间的聚合MOs），以便响应大小不会太大。如果结果响应大小大于发起者的最大可接受消息大小或大于本地最大消息大小，则错误状态字段将设置为“tooBig”。
Note that an aggregate MO can be defined only when all the constituent MO instances of interest are known. This scheme cannot be employed if a manager/application does not know the specific MO instances (of interest) that are serviced by the management target. In such cases, the application may "discover" the MO instances of interest by some means, e.g., by "walking" through the MIB tree on the agent. According to the results of the "walk", the application can define an appropriate aggregate MO that will serve the purpose. Considering the cost involved in this exercise, this method is recommended only if the aggregate MO will be used repeatedly, so that the benefits of aggregation outweigh the costs of configuration.
请注意，只有当所有感兴趣的组成MO实例都已知时，才能定义聚合MO。如果管理者/应用程序不知道管理目标所服务的特定MO实例（感兴趣），则无法使用此方案。在这种情况下，应用程序可以通过某种方式“发现”感兴趣的MO实例，例如，通过“遍历”代理上的MIB树。根据“漫游”的结果，应用程序可以定义一个合适的聚合任务单，以达到此目的。考虑到本练习涉及的成本，仅当聚合MO将重复使用时，才建议使用此方法，以便聚合的好处大于配置的成本。
The basic principle has been to keep the MIB as simple as possible and at the same time to make it flexible enough that a large number of users and applications can use the MIB to configure aggregate MOs conveniently.
基本原则是使MIB尽可能简单，同时使其足够灵活，以便大量用户和应用程序可以使用MIB方便地配置聚合MOs。
Two separate MIB modules have been defined. The AggrMIB supports the aggregation of independent MO instances, while TAggrMIB supports the aggregation of several samples of the same MO instance. Both of these MIB modules use the textual conventions defined in RMON-MIB [RFC2819] and SNMP-FRAMEWORK-MIB [RFC3411].
定义了两个独立的MIB模块。AggrMIB支持聚合独立的MO实例，而TAggrMIB支持聚合同一MO实例的多个样本。这两个MIB模块都使用RMON-MIB[RFC2819]和SNMP-FRAMEWORK-MIB[RFC3411]中定义的文本约定。
The AggrMIB is comprised of three tables, described below.
AggrMIB由三个表组成，如下所述。

There are management objects in the MIB modules defined in this document that have a MAX-ACCESS clause of read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. The objects and corresponding vulnerabilities are discussed below.
本文档中定义的MIB模块中有一些管理对象的MAX-ACCESS子句为read create。在某些网络环境中，此类对象可能被视为敏感或易受攻击。在没有适当保护的非安全环境中支持SET操作可能会对网络操作产生负面影响。下面讨论对象和相应的漏洞。
The following MOs are used to configure an agent that implements the aggregate MIB modules.
以下MOs用于配置实现聚合MIB模块的代理。
aggrCtlMOIndex, aggrCtlMODescr, aggrCtlCompressionAlgorithm, aggrCtlEntryOwner, aggrCtlEntryStorageType, aggrCtlEntryStatus, aggrMOInstance, aggrMODescr, aggrMOEntryStorageType, aggrMOEntryStatus, tAggrCtlMOInstance, tAggrCtlAgMODescr, tAggrCtlInterval, tAggrCtlSamples, tAggrCtlCompressionAlgorithm, tAggrCtlEntryOwner, tAggrCtlEntryStorageType, tAggrCtlEntryStatus,
aggrCtlMOIndex，aggrCtlMODescr，aggrCtlCompressionAlgorithm，AGGRCTLntryOwner，AGGRCTLntryStorageType，AGGRMTLntryStatus，aggrCtlMODescr，aggrCtlCompressionAlgorithm，AGGRCTLntryOwner，AGGRCTLntryCompressionAlgorithm，AGGRCTLntryOwner，AGGRCTLntryStorageType，TagGrctEntryStatus，
Access to these objects may be abused to affect the operation of the data collection system. In particular,
对这些对象的访问可能被滥用，从而影响数据采集系统的运行。特别地，
- by changing the value of an instance of aggrCtlEntryStatus, tAggrCtlEntryStatus, aggrMOEntryStatus, or tAggrMOEntryStatus to 'notInService' or 'destroy', the data aggregation operation for the corresponding entry will become unavailable to the management system.
- 通过将aggrCtlEntryStatus、tAggrCtlEntryStatus、aggrmentrystatus或tAggrMOEntryStatus实例的值更改为“notInService”或“destroy”，相应条目的数据聚合操作将对管理系统不可用。
- by changing the value of an instance of aggrMOInstance or tAggrCtlMOInstance, the data aggregation operation may be subverted. This may result in wrong information being fed to the management system.
- 通过更改aggrMOInstance或tAggrCtlMOInstance实例的值，可以颠覆数据聚合操作。这可能会导致向管理系统提供错误的信息。
- by adding several rows in the aggrMOTable corresponding to an aggregate MO, it is possible to make the value of the aggregate MOs very large. A similar effect may be achieved by manipulating the value of the tAggrCtlSamples instance corresponding to a Time-Based aggregate MO. This could result in very heavy management traffic and/or fragmentation of response packets. In some cases the responder may refuse to send the data and will simply respond with an error message indicating that the response packet size is too big.
- 通过在聚合任务单对应的聚合表中添加几行，可以使聚合任务单的值非常大。通过操纵与基于时间的聚合MO相对应的tAggrCtlSamples实例的值，可以实现类似的效果。这可能会导致非常大的管理流量和/或响应数据包的碎片。在某些情况下，响应者可能会拒绝发送数据，并简单地以错误消息进行响应，指示响应数据包大小过大。
An entity attempting to access an instance of an aggregated MO MUST have access rights to all the component instance objects and the aggregate MO instance. An implementation MUST follow this requirement. Lax adherence to this requirement will breach the security model and make the system vulnerable to illegal accesses.
试图访问聚合MO实例的实体必须具有对所有组件实例对象和聚合MO实例的访问权限。实现必须遵循此要求。不严格遵守这一要求将破坏安全模型，使系统容易受到非法访问的攻击。
SNMP versions prior to SNMPv3 did not include adequate security. 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 module.
SNMPv3之前的SNMP版本未包含足够的安全性。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模块中的对象。
It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
建议实施者考虑SNMPv3框架所提供的安全特性（参见[RCFC310]，第8节），包括对SNMPv3加密机制的完全支持（用于身份验证和隐私）。
Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them.
此外，不建议部署SNMPv3之前的SNMP版本。相反，建议部署SNMPv3并启用加密安全性。然后，客户/运营商应负责确保授予访问此MIB模块实例权限的SNMP实体已正确配置为仅授予那些拥有确实获取或设置（更改/创建/删除）对象的合法权限的主体（用户）访问对象。
The MIB modules in this document use the following IANA-assigned OBJECT IDENTIFIER values, recorded in the SMI Numbers registry:
本文档中的MIB模块使用以下IANA分配的对象标识符值，记录在SMI编号注册表中：
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
aggrMIB { experimental 123 }
tAggrMIB { experimental 124 }
Descriptor OBJECT IDENTIFIER value
