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[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, [RFC2578], STD 58, [RFC2579] and STD 58, [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、[RFC2578]、STD 58、[RFC2579]和STD 58、[RFC2580]所述。
The ForCES MIB module is a read-only MIB module that captures information related to the ForCES protocol ([RFC3654], [RFC3746], [FORCES-APP], and [RFC5810]).
ForCES MIB模块是一个只读MIB模块，用于捕获与ForCES协议相关的信息（[RFC3654]、[RFC3746]、[ForCES-APP]和[RFC5810]）。
The ForCES MIB module does not include information that is specified in other MIB modules, such as packet counters for interfaces, etc.
ForCES MIB模块不包括在其他MIB模块中指定的信息，例如接口的数据包计数器等。
More specifically, the information in the ForCES MIB module relative to associations (between Control Elements and Forwarding Elements) that are in the UP state includes:
更具体地说，ForCES MIB模块中与处于UP状态的关联（控制元件和转发元件之间）相关的信息包括：
o identifiers of the elements in the association,
o 关联中元素的标识符，
o configuration parameters of the association, and
o 关联的配置参数，以及
o statistics of the association.
o 协会的统计数字。
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 [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[RFC2119]中所述进行解释。
The MIB module contains the latest ForCES protocol version supported by the Control Element (CE) (forcesLatestProtocolVersionSupported). Note that the CE must also allow interaction with Forwarding Elements (FEs) supporting earlier versions.
MIB模块包含控制元件（CE）支持的最新ForCES协议版本（FORCESLATSTPROTOCOLVERSIONSUPPORTED）。请注意，CE还必须允许与支持早期版本的转发元素（FEs）进行交互。
For each association identified by the pair CE ID and FE ID, the following associated information is provided by the MIB module as an entry (forcesAssociationEntry) in the association table (forcesAssociationTable):
对于由配对CE ID和FE ID标识的每个关联，以下关联信息由MIB模块作为关联表（forcesAssociationTable）中的条目（forcesAssociationEntry）提供：
o Version number of the ForCES protocol running in this association (forcesAssociationRunningProtocolVersion).
o 在此关联中运行的ForCES协议的版本号（ForcessAssociationRunningProtocolVersion）。
o Time when the association entered the UP state (forcesAssociationTimeUp).
o 关联进入向上状态的时间（forcesAssociationTimeUp）。
o Time when the association left the UP state (forcesAssociationTimeDown). Note that this is only used for notification purposes as the association is removed from the MIB immediately after it leaves the UP state.
o 关联离开向上状态的时间（forcesAssociationTimeDown）。请注意，这仅用于通知目的，因为关联在离开UP状态后立即从MIB中删除。
o Number of ForCES Heartbeat messages sent from the CE (forcesAssociationHBMsgSent) and received by the CE (forcesAssociationHBMsgReceived) since the association entered the UP state.
o 自关联进入启动状态以来，从CE（forcesAssociationHBMsgSent）发送并由CE（forcesAssociationHBMsgReceived）接收的强制检测信号消息数。
o Number of operational ForCES messages sent from the CE (forcesAssociationOperMsgSent) and received by the CE (forcesAssociationOperMsgReceived) since the association entered the UP state. Only messages other than Heartbeat, Association Setup, Association Setup Response, and Association Teardown are counted.
o 自关联进入启动状态以来，从CE（forcesAssociationOperMsgSent）发送并由CE（forcesAssociationOperMsgReceived）接收的作战部队消息数。仅统计除心跳、关联设置、关联设置响应和关联拆卸之外的消息。
Finally, the MIB module defines the following notifications:
最后，MIB模块定义了以下通知：
o Whenever an association enters the UP state, a notification (forcesAssociationEntryUp) is issued containing the version of the ForCES protocol running. CE ID and FE ID are concatenated to form the table index, hence they appear in the OID of the ForCES-protocol running-version object. Optionally, a notification
o 每当关联进入UP状态时，都会发出通知（forcesAssociationEntryUp），其中包含正在运行的ForCES协议的版本。CE ID和FE ID连接起来形成表索引，因此它们出现在ForCES协议运行版本对象的OID中。（可选）通知
(forcesAssociationEntryUpStats) can instead be issued with all associated information for this association, except forcesAssociationTimeDown.
（forcesAssociationEntryUpStats）可以与此关联的所有关联信息一起发布，forcesAssociationTimeDown除外。
o Whenever an association leaves the UP state, a notification (forcesAssociationEntryDown) is issued containing the version of the ForCES protocol running. Optionally, a notification (forcesAssociationEntryDownStats) can instead be issued with all associated information for this association. The reason is that the association and all its associated information will be removed from the MIB immediately after this notification has been issued.
o 每当关联离开UP状态时，都会发出通知（forcesAssociationEntryDown），其中包含正在运行的ForCES协议的版本。或者，可以使用此关联的所有关联信息发布通知（forcesAssociationEntryDownStats）。原因是在发出此通知后，关联及其所有关联信息将立即从MIB中删除。

Associations enter the UP state as soon as the CE has sent to the FE an Association Setup Response message containing a successful Association Setup Result. Only associations that are UP are reflected in this MIB module.
一旦CE向FE发送了包含成功关联设置结果的关联设置响应消息，关联就会进入启动状态。只有向上的关联才会反映在此MIB模块中。
Associations are removed from the MIB module as soon as they leave the UP state, i.e., if the CE has not received any message (Heartbeat or other protocol message) from the FE within a given time period or if an Association Teardown message has been sent by the CE.
一旦关联离开启动状态，即如果CE在给定时间段内未从FE接收到任何消息（心跳或其他协议消息），或者如果CE已发送关联解除消息，则从MIB模块中移除关联。
Statistics counters are initialized to zero when the association is created. If the same association goes down and comes back up, the counters will reset and the discontinuity can be discovered by checking the discontinuity timestamp. In addition, the time-up timestamp in the association allows to distinguish new associations from past ones with the same index. Note that the optional down notification contains the statistics with the final values of the statistics counters.
创建关联时，统计计数器初始化为零。如果相同的关联下降并恢复，计数器将重置，并且可以通过检查中断时间戳来发现中断。此外，关联中的time-up时间戳允许将新关联与具有相同索引的过去关联区分开来。请注意，可选的down通知包含统计信息以及统计信息计数器的最终值。
An NE consists of one or more FEs and one or more CEs. Where there is a single CE, that CE will have knowledge of all the associations in the NE and so can provide the information necessary to support the managed objects defined in this MIB module. Where there is more than one CE, information about the associations may be distributed among the CEs. Whether each CE implements the managed objects for the associations of which it is aware or whether the CEs cooperate to present the appearance of a single set of managed objects for all the associations in the NE is outside the scope of this document.
网元由一个或多个FEs和一个或多个CE组成。当存在单个CE时，该CE将了解网元中的所有关联，因此可以提供支持此MIB模块中定义的托管对象所需的信息。如果存在多个CE，则可在CE之间分发关于关联的信息。每个CE是否为其知道的关联实现托管对象，或者CE是否合作为网元中的所有关联呈现单个托管对象集的外观，不在本文档的范围内。
There are no management objects defined in this MIB module that have a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET operations.
此MIB模块中未定义具有读写和/或读创建MAX-ACCESS子句的管理对象。因此，如果此MIB模块实现正确，则入侵者不会通过直接的SNMP集操作更改或创建此MIB模块的任何管理对象。
Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability:
在某些网络环境中，此MIB模块中的某些可读对象（即具有MAX-ACCESS而非not ACCESS的对象）可能被视为敏感或易受攻击。因此，在通过SNMP通过网络发送这些对象时，控制甚至获取和/或通知对这些对象的访问，甚至可能加密这些对象的值，这一点非常重要。以下是表和对象及其敏感度/漏洞：
o Objects in the forcesMibGroup are protocol versions. They are neither sensitive nor vulnerable.
o forcesMibGroup中的对象是协议版本。他们既不敏感也不脆弱。
o Objects in the forcesStatsGroup are statistics. They are neither sensitive nor vulnerable.
o forcesStatsGroup中的对象是统计信息。他们既不敏感也不脆弱。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), even then, 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），即使如此，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
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。然后是客户/运营商
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.
有责任确保授予访问此MIB模块实例权限的SNMP实体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。
