Abstract
摘要
This memo defines a Management Information Base (MIB) module that contains textual conventions (TCs) to represent commonly used pseudowire (PW) management information. The intent is that these TCs will be imported and used in PW-related MIB modules that would otherwise define their own representations.
此备忘录定义了一个管理信息库（MIB）模块，该模块包含文本约定（TC），以表示常用的伪线（PW）管理信息。其目的是将这些TC导入并用于PW相关的MIB模块中，否则这些模块将定义它们自己的表示形式。

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines textual conventions used for pseudowire (PW) technology and for Pseudowire Edge-to-Edge Emulation (PWE3) MIB modules.
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，它定义了用于伪线（PW）技术和伪线边到边仿真（PWE3）MIB模块的文本约定。
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410].
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 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）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。
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。

This module does not define any management objects. Instead, it defines a set of textual conventions that may be used by other PWE3 MIB modules to define management objects.
此模块不定义任何管理对象。相反，它定义了一组文本约定，其他PWE3 MIB模块可以使用这些文本约定来定义管理对象。
Meaningful security considerations can only be written in the MIB modules that define management objects. Therefore, this document has no impact on the security of the Internet.
有意义的安全注意事项只能写入定义管理对象的MIB模块中。因此，本文件不影响互联网的安全。
The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER value recorded in the SMI Numbers registry:
