This document describes a model for managing pseudowire services for transmission over different flavors of MPLS tunnels. The general PW MIB module [RFC5601] defines the parameters global to the PW regardless of the underlying Packet Switched Network (PSN) and emulated service. This document is applicable for PWs that use MPLS PSN type in the PW-STD-MIB.
本文档描述了一个用于管理伪线服务的模型，用于在不同类型的MPLS隧道上传输。通用PW MIB模块[RFC5601]定义PW的全局参数，而不考虑底层分组交换网络（PSN）和模拟服务。本文件适用于PW-STD-MIB中使用MPLS PSN类型的PW。
This document describes the MIB objects that define pseudowire association to the MPLS PSN, in a way that is not specific to the carried service.
本文档描述了定义与MPLS PSN的伪线关联的MIB对象，其方式不特定于所承载的服务。
Together, [RFC3811] and [RFC3812] describe the modeling of an MPLS tunnel, and a tunnel's underlying cross-connects. This MIB module supports MPLS-TE PSN, non-TE MPLS PSN (an outer tunnel created by the Label Distribution Protocol (LDP) or manually), and MPLS PW label only (no outer tunnel).
[RFC3811]和[RFC3812]共同描述了MPLS隧道的建模以及隧道的底层交叉连接。此MIB模块仅支持MPLS-TE PSN、非TE MPLS PSN（由标签分发协议（LDP）或手动创建的外部隧道）和MPLS PW标签（无外部隧道）。
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
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。此备忘录指定了一个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].
符合SMIv2的模块，如STD 58、RFC 2578[RFC2578]、STD 58、RFC 2579[RFC2579]和STD 58、RFC 2580[RFC2580]所述。
This document uses terminology from the document describing the PW architecture [RFC3985], [RFC3916], and [RFC4447].
本文件使用描述PW体系结构[RFC3985]、[RFC3916]和[RFC4447]的文件中的术语。
The terms "outbound" and "inbound" in this MIB module are based on the common practice in the MPLS standards; i.e. "outbound" is toward the PSN. However, where these terms are used in an object name, the object description clarifies the exact packet direction to prevent confusion with these terms in other documents.
此MIB模块中的术语“出站”和“入站”基于MPLS标准中的常见实践；i、 e.“出站”指向PSN。但是，如果在对象名称中使用这些术语，则对象描述澄清了确切的数据包方向，以防止与其他文档中的这些术语混淆。
"PSN tunnel" is a general term indicating a virtual connection between the two Pseudowire Emulation Edge-to-Edge (PWE3) edge devices. Each tunnel may potentially carry multiple PWs inside. An MPLS tunnel is within the scope of this document.
“PSN隧道”是一个通用术语，表示两个伪线仿真边到边（PWE3）边缘设备之间的虚拟连接。每个隧道可能在内部承载多个PW。MPLS隧道在本文档的范围内。
This document uses terminology from the document describing the MPLS architecture [RFC3031] for MPLS PSN. A Label Switched Path (LSP) is modeled as described in [RFC3811] and [RFC3812] via a series of cross-connects through one or more Label Switching Routers (LSRs).
本文档使用描述MPLS PSN的MPLS体系结构[RFC3031]的文档中的术语。标签交换路径（LSP）的建模如[RFC3811]和[RFC3812]所述，通过一个或多个标签交换路由器（LSR）的一系列交叉连接。
In MPLS PSN, a PW connection typically uses a PW label within a tunnel label [RFC4447]. Multiple pseudowires each with a unique PW label can share the same tunnel. For PW transport over MPLS, the tunnel label is known as the "outer" label, while the PW label is known as the "inner" label. An exception to this is with adjacent LSRs or the use of a Penultimate Hop Popping (PHP). In this case, there is an option for PWs to connect directly without an outer label.
在MPLS PSN中，PW连接通常在隧道标签内使用PW标签[RFC4447]。具有唯一PW标签的多条伪线可以共享同一通道。对于MPLS上的PW传输，隧道标签称为“外部”标签，而PW标签称为“内部”标签。一个例外是相邻的LSR或使用倒数第二跳弹出（PHP）。在这种情况下，PWs可以选择不使用外部标签直接连接。
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 RFC 2119 [BCP14].
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RFC 2119[BCP14]中所述进行解释。
The MIB module structure for defining a PW service consists of three layers of MIB modules functioning together. This general model is defined in the PWE3 architecture [RFC3985]. The layering model is intended to sufficiently isolate PW services from the underlying PSN layer that carries the emulated service. This is done at the same time as providing a standard means for connecting any supported services to any supported PSNs.
用于定义PW服务的MIB模块结构由三层MIB模块组成，它们一起工作。该通用模型在PWE3体系结构[RFC3985]中定义。分层模型旨在将PW服务与承载模拟服务的底层PSN层充分隔离。这与提供将任何受支持的服务连接到任何受支持的PSN的标准方法同时完成。
The first layer, known as the service layer, contains service-specific modules. These modules define service-specific management objects that interface or collaborate with existing MIB modules for the native version of the service. The service-specific module "glues" the standard modules to the PWE3 MIB modules.
第一层称为服务层，包含特定于服务的模块。这些模块定义特定于服务的管理对象，这些对象与服务本机版本的现有MIB模块进行接口或协作。特定于服务的模块将标准模块“粘合”到PWE3 MIB模块。
The next layer of the PWE3 MIB structure is the PW MIB module [RFC5601]. This module is used to configure general parameters of PWs that are common to all types of emulated services and PSNs. This layer is connected to the service-specific layer above and the PSN layer below.
PWE3 MIB结构的下一层是PW MIB模块[RFC5601]。此模块用于配置PWs的通用参数，这些参数对于所有类型的仿真服务和PSN都是通用的。该层连接到上面的服务特定层和下面的PSN层。
The PSN layer provides PSN-specific modules for each type of PSN. These modules associate the PW with one or more "tunnels" that carry the service over the PSN. These modules are used to "glue" the PW service to the underlying PSN-specific MIB modules. This document defines the MIB module for PW over MPLS PSN.
PSN层为每种类型的PSN提供特定于PSN的模块。这些模块将PW与通过PSN承载服务的一个或多个“隧道”相关联。这些模块用于将PW服务“粘合”到底层特定于PSN的MIB模块。本文档定义了MPLS PSN上PW的MIB模块。
[RFC5542] defines some of the object types used in these modules.
[RFC5542]定义了这些模块中使用的一些对象类型。
The PW-MPLS-STD-MIB module is designed to satisfy the following requirements and constraints:
PW-MPLS-STD-MIB模块旨在满足以下要求和约束：
- The MIB module supports both manually configured and signaled PWs.
- MIB模块支持手动配置和信号PWs。
- The MIB module supports point-to-point PW connections.
- MIB模块支持点对点PW连接。
- The MIB module enables the use of any emulated service.
- MIB模块支持使用任何模拟服务。
- The MIB module supports MPLS-TE outer tunnel, non-TE MPLS outer tunnel (an outer tunnel signaled by LDP or set up manually), and no outer tunnel (where the PW label is the only label in the MPLS stack). The latter case is applicable for manual configuration of PW over a single hop, as for signaled MPLS PSN even across a single hop there is an MPLS tunnel -- even though the actual packet may not contain the MPLS tunnel label due to PHP.
- MIB模块支持MPLS-TE外部隧道、非TE MPLS外部隧道（由LDP发出信号或手动设置的外部隧道）和无外部隧道（其中PW标签是MPLS堆栈中的唯一标签）。后一种情况适用于在单跳上手动配置PW，因为对于信号MPLS PSN，即使在单跳上，也存在MPLS隧道——即使由于PHP的原因，实际数据包可能不包含MPLS隧道标签。
The MIB module uses Textual Conventions (TCs) from [RFC2578], [RFC2579], [RFC2580], [RFC2863], [RFC3811], [RFC3813], [RFC5542], and [RFC5601].
MIB模块使用[RFC2578]、[RFC2579]、[RFC2580]、[RFC2863]、[RFC3811]、[RFC3813]、[RFC5542]和[RFC5601]中的文本约定（TC）。
- The PW table (pwTable) in [RFC5601] is used for all PW types (ATM, FR, Ethernet, SONET, etc.). This table contains high-level generic parameters related to the PW creation. The operator or the agent creates a row for each PW.
- [RFC5601]中的PW表（pwTable）用于所有PW类型（ATM、FR、以太网、SONET等）。此表包含与PW创建相关的高级通用参数。操作员或代理为每个PW创建一行。
- If the selected PSN type in the pwTable is MPLS, the agent creates a row in the MPLS-specific parameters table (pwMplsTable) in this module, which contains MPLS-specific parameters such as EXP bits handling and outer tunnel configuration.
- 如果PWS表中选择的PSN类型是MPLS，则代理程序将在此模块中的MPLS特定参数表（pwMplsTable）中创建一行，其中包含MPLS特定参数，例如EXP位处理和外部隧道配置。
- The operator configures the association to the desired MPLS tunnel (required for MPLS-TE tunnels or for manually configured PWs) through the pwMplsTeOutboundTable. For the LDP-based outer tunnel, there is no need for manual configuration since there is only a single tunnel toward the peer.
- 操作员通过pwMplsTeOutboundTable配置与所需MPLS隧道（MPLS-TE隧道或手动配置的PWs所需）的关联。对于基于LDP的外部隧道，不需要手动配置，因为只有一个通向对等方的隧道。
- The agent creates rows in the MPLS mapping table in order to allow quick retrieval of information based on the tunnel indexes.
- 代理在MPLS映射表中创建行，以便基于隧道索引快速检索信息。
The relation to the MPLS network is by configuration of the edge LSR only -- i.e., the LSR that provides the PW function. Since tunnels are unidirectional, a pair of tunnels MUST exist (one for inbound, one for outbound). Figure 1 depicts a PW that originates and terminates at LSR-M. It uses tunnels A and B formed by cross-connects (XCs) Ax and Bx continuing through LSR-N to LSR-P. The concatenations of XCs create the tunnels. Note: 'X' denotes a tunnel's cross-connect.
与MPLS网络的关系仅通过边缘LSR的配置实现——即，提供PW功能的LSR。由于隧道是单向的，因此必须存在一对隧道（一个用于入站，一个用于出站）。图1描述了在LSR-M处发起和终止的PW。它使用交叉连接（XCs）Ax和Bx形成的隧道a和B，通过LSR-N继续连接到LSR-P。XCs的连接创建隧道。注：“X”表示隧道的交叉连接。

图1:MPLS上的PW建模
The PW-MPLS-STD-MIB supports three options for an MPLS network:
PW-MPLS-STD-MIB支持MPLS网络的三个选项：
(1) In the MPLS-TE case, tunnels A and B are created via the MPLS-TE-STD-MIB [RFC3812]. The tunnels are associated (in each peer independently) to the PW by the four indexes that uniquely identify the tunnel at the MPLS-TE-STD-MIB.
(1) 在MPLS-TE情况下，隧道A和B通过MPLS-TE-STD-MIB[RFC3812]创建。隧道通过在MPLS-TE-STD-MIB处唯一标识隧道的四个索引与PW相关联（在每个对等方中独立）。
(2) In the non-TE case, tunnels A1 and B1 are either manually configured or set up with LDP. The tunnels are associated to the PW by the XC index in the MPLS-LSR-STD-MIB [RFC3813].
(2) 在非TE情况下，隧道A1和B1要么手动配置，要么使用LDP设置。隧道通过MPLS-LSR-STD-MIB[RFC3813]中的XC索引与PW相关联。
(3) In the PW-label-only case, there is no outer tunnel on top of the PW label. This case is useful in the case of adjacent Provider Edges (PEs) in manual configuration mode. Note that for signaled tunnels, when LSR-N acts as PHP for the outer tunnel label, there are still entries for the outer tunnel in the relevant MPLS MIB modules, so even for the case of adjacent LSRs, the relevant mode is either MPLS-TE or non-TE.
(3) 在仅PW标签的情况下，PW标签顶部没有外部通道。这种情况在手动配置模式下相邻提供程序边缘（PE）的情况下非常有用。注意，对于信号隧道，当LSR-N充当外部隧道标签的PHP时，在相关MPLS MIB模块中仍然存在外部隧道的条目，因此即使对于相邻LSR的情况，相关模式也是MPLS-TE或非TE。
A combination of MPLS-TE outer tunnel(s) and LDP outer tunnel for the same PW is allowed through the pwMplsOutboundTunnel. The current tunnel that is used to forward traffic is indicated in the object pwMplsOutboundTunnelTypeInUse.
允许同一PW的MPLS-TE外部隧道和LDP外部隧道的组合通过pwMplsOutboundTunnel。用于转发流量的当前隧道在对象pwMplsOutboundTunnelTypeInUse中指示。
The PW-MPLS-STD-MIB module reports through the inbound table the XC entry in the LDP-STD-MIB [RFC3815] of the PW that was signaled through LDP.
PW-MPLS-STD-MIB模块通过入站表报告通过LDP发送信号的PW的LDP-STD-MIB[RFC3815]中的XC条目。
This MIB module assumes that a PW can be associated to one MPLS-TE tunnel at a time. This tunnel may be composed of multiple instances (i.e., LSP), each represented by a separate instance index. The selection of the active LSP out of the possible LSPs in the tunnel is out of the scope of this MIB module as it is part of the MPLS PSN functionality. The current active LSP is reported through this MIB module.
该MIB模块假设一个PW一次可以关联到一个MPLS-TE隧道。该隧道可由多个实例（即LSP）组成，每个实例由单独的实例索引表示。从隧道中可能的LSP中选择活动LSP超出此MIB模块的范围，因为它是MPLS PSN功能的一部分。当前活动LSP通过此MIB模块报告。
It is important to note that inbound (tunnel originated in the remote PE) mapping is not configured or reported through the PW-MPLS-STD-MIB module since the local PE does not know the inbound association between specific PW and MPLS tunnels.
需要注意的是，入站（源自远程PE的隧道）映射未通过PW-MPLS-STD-MIB模块配置或报告，因为本地PE不知道特定PW和MPLS隧道之间的入站关联。
The following example (supplement the example provided in [RFC5601]) assumes that the node has already established the LDP tunnel to the peer node and that a PW has been configured in the pwTable in [RFC5601] with pwPsnType equal 'mpls'.
以下示例（补充[RFC5601]中提供的示例）假设节点已建立到对等节点的LDP隧道，并且已在[RFC5601]中的PW表中配置PW，pwPsnType等于“mpls”。
The agent creates an entry in pwMplsTable with the following parameters:
代理使用以下参数在pwMplsTable中创建一个条目：
pwMplsMplsType mplsNonTe(1), -- LDP tunnel pwMplsExpBitsMode outerTunnel(1), -- Default pwMplsExpBits 0, -- Default pwMplsTtl 2, -- Default pwMplsLocalLdpID 192.0.2.200:0, pwMplsLocalLdpEntityIndex 1, pwMplsPeerLdpID 192.0.2.5:0, pwMplsStorageType nonVolatile(3)
pwMplsMplsType mplsNonTe（1），--LDP隧道PWMPLSEPITSPMODE outerTunnel（1），--默认PWMPLSEPITS 0，--默认pwMplsTtl 2，--默认PWMPLSOLCallDPID 192.0.2.200:0，PWMPLSOLCallDPEntityIndex 1，PWMPLSPerlDPID 192.0.2.5:0，PWMPLSStorage Type非易失性（3）
The agent also creates an entry in pwMplsOutboundTable for reporting the mapping of the PW on the LDP tunnel:
代理还在pwMplsOutboundTable中创建一个条目，用于报告LDP隧道上PW的映射：
pwMplsOutboundLsrXcIndex 100, - The XC number for the -- LDP tunnel pwMplsOutboundTunnelIndex 0, -- No TE tunnel pwMplsOutboundTunnelInstance 0, -- No TE tunnel pwMplsOutboundTunnelLclLSR 0, -- No TE tunnel pwMplsOutboundTunnelPeerLSR 0, -- No TE tunnel pwMplsOutboundIfIndex 0, -- Not applicable pwMplsOutboundTunnelTypeInUse mplsNonTe(3)
PWMPLSOUTBOUNTBOUNDLSRXCDINDEX 100，-LDP隧道的XC编号PWMPLSOUTBOUNTBOUNDTUNNELINDEX 0，-无TE隧道PWMPLSOUTBOUNTBOUNDTUNNELLSTCLLSR 0，-无TE隧道PWMPLSOUNTBOUNDTUNNELLSTEERLSR 0，-无TE隧道PWMPLSOUTBOUNTBOUNDIFINDEX 0，-不适用PWMPLSOUTBOUNTBOUNDTUNDTUNNELLTYPENUSE MPSNENTE（3）
The agent now creates entries for the PW in the following tables:
代理现在在下表中为PW创建条目：
- pwMplsInboundTable
- pwMplsInboundTable
- pwMplsNonTeMappingTable (2 entries)
- PWMPLSnoneMappingTable（2个条目）
To create an MPLS-TE tunnel to carry this PW, the operator takes the following steps:
要创建一个MPLS-TE隧道来承载此PW，运营商应采取以下步骤：
- Set pwMplsMplsType in pwMplsTable to both mplsNonTe(1) and mplsTe(0).
- 将pwMplsTable中的pwMplsMplsType设置为mplsNonTe（1）和mplsTe（0）。
- Set pwMplsOutboundTunnelIndex, pwMplsOutboundTunnelInstance, pwMplsOutboundTunnelLclLSR, and pwMplsOutboundTunnelPeerLSR in pwMplsOutboundTable to the MPLS-TE tunnel that will carry this PW.
- 将pwMplsOutboundTunnelIndex、pwMplsOutboundTunnelInstance、PWMPLSOUTBOUNDTUNNELCLLSR和pwMplsOutboundTunnelPeerLSR设置为将承载此PW的MPLS-TE隧道。
The agent will report the tunnel that the PW is currently using through pwMplsOutboundTunnelTypeInUse, and will report the PW to MPLS-TE tunnel/LSP mapping in pwMplsTeMappingTable.
代理将通过PWMPLSOUTBOUNDTUNNELTYPENUSE报告PW当前使用的隧道，并将PW报告到pwMplsTeMappingTable中的MPLS-TE隧道/LSP映射。

STATUS current DESCRIPTION "A row in this table represents parameters specific to MPLS PSN for a pseudowire (PW). The row is created automatically by the local agent if the pwPsnType is mpls(1). It is indexed by pwIndex, which uniquely identifies a singular PW. Manual entries in this table SHOULD be preserved after a reboot, and the agent MUST ensure the integrity of those entries. If the set of entries of a specific row were found to be nonconsistent after reboot, the PW pwOperStatus MUST be declared as down(2). Any read-write object in this table MAY be changed at any time; however, change of some objects (for example, pwMplsMplsType) during PW forwarding state MAY cause traffic disruption."
STATUS current DESCRIPTION“此表中的一行表示特定于伪线（PW）的MPLS PSN的参数。如果pwPsnType为MPLS（1），则该行由本地代理自动创建。它由pwIndex索引，pwIndex唯一标识单个PW。重新启动后应保留此表中的手动条目，并且代理必须确保这些条目的完整性。如果重新启动后发现特定行的一组条目不一致，则必须将PW pwOperStatus声明为down（2）。此表中的任何读写对象都可以随时更改；但是，在PW转发状态期间更改某些对象（例如，pwMplsMplsType）可能会导致通信中断。“

此表指向相应的MPLS MIB模块：
In the MPLS-TE case, the three objects relevant to the indexing of a TE tunnel head-end (as used in the MPLS-TE-STD-MIB) are to be configured, and the tunnel instance indicates the LSP that is currently in use for forwarding the traffic.
在MPLS-TE情况下，将配置与TE隧道头端的索引相关的三个对象（如MPLS-TE-STD-MIB中使用的），并且隧道实例指示当前用于转发业务的LSP。
In the case of signaled non-TE MPLS (an outer tunnel label assigned by LDP), the table points to the XC entry in the LSR-STD-MIB. If the non-TE MPLS tunnel is manually configured, the operator configures the XC pointer to this tunnel.
在有信号的非TE MPLS（LDP分配的外部隧道标签）的情况下，该表指向LSR-STD-MIB中的XC条目。如果手动配置非TE MPLS隧道，则操作员配置指向此隧道的XC指针。
In the case of PW label only (no outer tunnel), the ifIndex of the port to carry the PW is configured here.
在仅PW标签的情况下（无外部通道），此处配置用于承载PW的端口的ifIndex。
It is possible to associate a PW to one TE tunnel head-end and a non-TE tunnel together. An indication in this table will report the currently active one. In addition, in the TE case, the table reports the active tunnel instance (i.e., the specific LSP in use). Any read-write object in this table MAY be changed at any time; however, change of some objects (for example, MPLS-TE indexes) during PW forwarding state MAY cause traffic disruption."
可以将PW与一个TE隧道头端和一个非TE隧道连接在一起。此表中的指示将报告当前活动的指示。此外，在TE情况下，该表报告活动隧道实例（即，正在使用的特定LSP）。此表中的任何读写对象均可随时更改；但是，在PW转发状态期间更改某些对象（例如，MPLS-TE索引）可能会导致通信中断。”

- 如果PW已通过信令协议（即pwOwner equal pwIdFecSignaling（2）或genFecSignaling（3））设置，则代理会为入站方向创建一行（pwMplsNonTeMappingDirection设置为fromPsn（2））。PWMPLSNNetemappingXCIndex保存PW LDP生成的XC条目的MPLS-LSR-STD-MIB中的XC索引。对于此行，pwMplsNonTeMappingIfIndex必须为零。

It is clear that this MIB module is potentially useful for monitoring PW-capable PEs. This MIB module can also be used for configuration of certain objects, and anything that can be configured can be incorrectly configured, with potentially disastrous results.
很明显，该MIB模块对于监控具有PW功能的PEs可能非常有用。此MIB模块还可用于配置某些对象，可以配置的任何内容都可能被错误配置，从而导致潜在的灾难性后果。
There are number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or 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. These are the tables and objects and their sensitivity/vulnerability:
此MIB模块中定义了多个管理对象，其MAX-ACCESS子句为read-write和/或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。以下是表和对象及其敏感度/漏洞：
o the pwMplsTable, pwMplsNonTeMappingTable and pwMplsTeMappingTable collectively contain objects to provision PW over MPLS tunnels. Unauthorized access to objects in these tables, could result in disruption of traffic on the network. The use of stronger mechanisms such as SNMPv3 security should be considered where possible. Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent which implements this MIB module. Administrators should consider whether read access to these objects should be allowed, since read access may be undesirable under certain circumstances.
o pwMplsTable、pwMplsNonTeMappingTable和pwMplsTeMappingTable共同包含通过MPLS隧道提供PW的对象。未经授权访问这些表中的对象可能会导致网络流量中断。在可能的情况下，应考虑使用更强的机制，如SNMPv3安全性。具体来说，SNMPv3 VACM和USM必须与实现此MIB模块的任何v3代理一起使用。管理员应该考虑是否应该允许对这些对象的读访问，因为在某些情况下读访问可能是不可取的。
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 the pwMplsTable, pwMplsNonTeMappingTable, pwMplsTeMappingTable and pwMplsOutboundTable collectively show the PW over MPLS association. If an Administrator does not want to reveal this information, then these tables should be considered sensitive/ vulnerable.
o pwMplsTable、pwMplsNonTeMappingTable、pwMplsTeMappingTable和PWMPLSOUTBOUNDBOUNDTABLE共同显示PW-over-MPLS关联。如果管理员不想透露此信息，则应将这些表视为敏感/易受攻击。
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 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合法权限来获取或设置（更改/创建/删除）对象的主体（用户）访问对象的权限。
