This memo defines how label-switching-controlled Frame-Relay [RFC3034] and ATM [RFC3035] interfaces can be realized given the interface stacking as defined in the MPLS-LSR-STD [RFC3813] and MPLS-TE-STD [RFC3812] MIBs. This document also contains a MIB module that sparsely extends the MPLS-LSR-STD MIB's mplsInterfaceConfTable in such a way as to identify which MPLS-type interfaces have LC-ATM or LC-FR capabilities. Comments should be made directly to the MPLS mailing list at mpls@uu.net.
本备忘录定义了在MPLS-LSR-STD[RFC3813]和MPLS-TE-STD[RFC3812]MIB中定义的接口堆叠条件下，标签交换控制帧中继[RFC3034]和ATM[RFC3035]接口的实现方式。本文档还包含一个MIB模块，该模块稀疏地扩展了MPLS-LSR-STD MIB的mplsInterfaceConfTable，以确定哪些MPLS类型接口具有LC-ATM或LC-FR功能。应直接向MPLS邮件列表提出意见，地址为mpls@uu.net.
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, reference [RFC2119].
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不得”、“应”、“不应”、“建议”、“可”和“可选”应按照RFC 2119，参考文献[RFC2119]中的描述进行解释。
This document uses terminology from the document describing the MPLS architecture [RFC3031], as well as from RFC 3035 and RFC 3034. Specifically, the following terms will be used in this document.
本文件使用了描述MPLS体系结构的文件[RFC3031]以及RFC 3035和RFC 3034中的术语。具体而言，本文件将使用以下术语。
C-FR RFC 3034 defines a label-switching-controlled Frame Relay (LC-FR) interface. Packets traversing such an interface carry labels in the DLCI field
C-FR RFC 3034定义了标签交换控制帧中继（LC-FR）接口。通过这种接口的数据包在DLCI字段中携带标签
C-ATM RFC 3035 defines a label-switching-controlled ATM (LC-ATM) interface as an ATM interface controlled by the label switching control component. When a packet traversing such an interface is received, it is treated as a labeled packet. The packet's top label is inferred from either the contents of the Virtual Channel Identifier (VCI) field or the combined contents of the Virtual Path Identifier (VPI) and VCI fields. Any two LDP peers that are connected via an LC-ATM interface will use LDP negotiations to determine which of these cases is applicable to that interface. Static configuration of labels is also possible.
C-ATM RFC 3035将标签交换控制的ATM（LC-ATM）接口定义为由标签交换控制组件控制的ATM接口。当接收到穿过此类接口的数据包时，它将被视为带标签的数据包。根据虚拟通道标识符（VCI）字段的内容或虚拟路径标识符（VPI）和VCI字段的组合内容推断数据包的顶部标签。通过LC-ATM接口连接的任何两个LDP对等点将使用LDP协商来确定这些情况中的哪一种适用于该接口。标签的静态配置也是可能的。
When LDP is used to distribute labels for use on label-controlled interfaces, label configuration information may be available in the MPLS-LDP-ATM-STD-MIB [RFC3815] when LC-ATM interfaces are used, or the MPLS-LDP-FRAME-RELAY-STD-MIB [RFC3815] when LC-FR interfaces are used.
当LDP用于分发标签以在标签控制接口上使用时，当使用LC-ATM接口时，标签配置信息可在MPLS-LDP-ATM-STD-MIB[RFC3815]中获得，或当使用LC-FR接口时，在MPLS-LDP-FRAME-RELAY-STD-MIB[RFC3815]中获得。
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 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。
Since LC-ATM interfaces [RFC2863] can carry labeled MPLS traffic, they too are considered MPLS subinterfaces with ifType = mpls(166). They differ slightly in their capability from a packet-oriented MPLS interface in that they may carry ATM- or Frame-Relay-encapsulated traffic. It is thus beneficial to identify them as such. To do this, two tables are defined that extend the MPLS-LSR-STD MIB's mplsInterfaceTable (see section 5 for LC-ATM or section 6 for LC-FR).
由于LC-ATM接口[RFC2863]可以承载标记的MPLS流量，因此它们也被视为ifType=MPLS（166）的MPLS子接口。它们的性能与面向分组的MPLS接口稍有不同，因为它们可以承载ATM或帧中继封装的流量。因此，将它们识别出来是有益的。为此，定义了两个扩展MPLS-LSR-STD MIB的MPLSINTERFACTABLE的表（LC-ATM见第5节，LC-FR见第6节）。
The MPLS-LC-ATM-STD-MIB module is structured simply as a table of entries that sparsely extend those found in the interfaces table. In particular, the entries in the mplsLcAtmStdInterfaceConfTable extend interfaces capable of supporting MPLS, as is defined in [RFC3813], to include entries that also support LC-ATM (and their unique attributes). Therefore, the module can be visualized as follows. Note that the ifTable comes from [RFC2863], the mplsInterfaceTable from [RFC3813], and the mplsLcAtmStdInterfaceConfTable from the MPLS-LC-ATM-STD-MIB module described below.
MPLS-LC-ATM-STD-MIB模块的结构简单，是一个条目表，它稀疏地扩展了接口表中的条目。具体而言，如[RFC3813]中所定义，MPLSCATMSTDinterfaceConfTable中的条目扩展了能够支持MPLS的接口，以包括也支持LC-ATM的条目（及其唯一属性）。因此，该模块可以可视化如下。请注意，ifTable来自[RFC2863]，mplsInterfaceTable来自[RFC3813]，MPLSLCATMSTDInterfaceConfitable来自下面描述的MPLS-LC-ATM-STD-MIB模块。
ifTable mplsInterfaceTable mplsLcAtmStdInterfaceConfTable .1 .2 .2 .3 .4 .4 .4 .5
ifTable MPLS可折叠MPLSCATMSTDinterfaceconftable.1.2.2.3.4.4.5
In the example shown above, five interfaces exist on the device in question. Of those interfaces, those with ifIndex = .2 and .4 are of ifType = mpls(166) indicating that they are capable of MPLS. Of those two, the entry with index .4 is capable of MPLS LC-ATM operations.
在上面所示的示例中，所讨论的设备上存在五个接口。在这些接口中，ifIndex分别为.2和.4的接口的ifType=mpls（166）表示它们能够使用mpls。其中，索引为.4的条目能够进行MPLS LC-ATM操作。
Note that the label partition model utilized by the authors of this document reflects widespread implementation and is seen by the MPLS working group as sufficiently flexible to meet the operational needs, even if it is more restrictive than [RFC3035] allows. To this end, we have limited the control and unlabeled VPI and VCI to single values. Note that mplsLcAtmStdUnlabTrafVci and mplsLcAtmStdCtrlVci MUST not be equal; nor should mplsLcAtmStdCtrlVpi or mplsLcAtmStdUnlabTrafVpi be equal.
请注意，本文件作者使用的标签分区模型反映了广泛的实施，MPLS工作组认为该模型具有足够的灵活性，能够满足运营需求，即使其限制性比[RFC3035]允许的更大。为此，我们将控制和未标记的VPI和VCI限制为单个值。请注意，mplslcatmstdunlabtravci和mplsLcAtmStdCtrlVci不得相等；mplsLcAtmStdCtrlVpi或MPLSLCATMSTDUNLABTRAVPI也不应相等。
The MPLS-LC-FR-STD-MIB module is structured simply as a table of entries that sparsely extend those found in the interfaces table. In particular, the entries in the mplsLcFrStdInterfaceConfTable extend interfaces capable of supporting MPLS, as is defined in [RFC3813], to include entries that also support LC-Frame Relay (and their unique attributes). Therefore, the module can be visualized as follows. Note that the ifTable comes from [RFC2863], the mplsInterfaceTable from [RFC3813], and the mplsLcAtmStdInterfaceConfTable from the MPLS-LC-FR-STD-MIB module described below.
MPLS-LC-FR-STD-MIB模块的结构简单，是一个条目表，它稀疏地扩展了interfaces表中的条目。具体而言，如[RFC3813]中所定义，MPLSLCFSTDinterfaceConfTable中的条目扩展了能够支持MPLS的接口，以包括也支持LC帧中继（及其唯一属性）的条目。因此，该模块可以可视化如下。请注意，ifTable来自[RFC2863]，mplsInterfaceTable来自[RFC3813]，mplsLcAtmStdInterfaceConfTable来自下面描述的MPLS-LC-FR-STD-MIB模块。
ifTable mplsInterfaceTable mplsLcFrStdInterfaceConfTable .1 .2 .2 .3 .4 .4 .4 .5
ifTable MPLSINTERFACTBLE MPLSLCFRS TDINTERFACECONTABLE.1.2.2.3.4.4.4.5
In the example shown above, five interfaces exist on the device in question. Of those interfaces, those with ifIndex = .2 and .4 are of ifType = mpls(166) indicating that they are capable of MPLS. Of those two, the entry with index .4 is capable of MPLS LC-Frame Relay operations.
在上面所示的示例中，所讨论的设备上存在五个接口。在这些接口中，ifIndex分别为.2和.4的接口的ifType=mpls（166）表示它们能够使用mpls。其中，索引为.4的条目能够执行MPLS LC帧中继操作。
Note that even though the architecture as described in [RFC3034] calls for supporting mixed labeled and unlabeled traffic, this MIB does not support that, as this capability does not seem to be used operationally. Note that the DLCI ranges represented by mplsLcFrStdTrafficMinDlci to mplsLcFrStdTrafficMaxDlci and mplsLcFrStdCtrlMinDlci to mplsLcFrStdCtrlMaxDlci MUST not overlap.
请注意，尽管[RFC3034]中所述的体系结构要求支持混合标记和未标记的流量，但该MIB不支持这一点，因为该功能似乎未在操作中使用。请注意，由MPLSLCFSTDTRAFFICMINDLCI到MPLSLCFSTDTRAFFICMAXDLCI和MPLSLCFSTDCTRLMINDLCI到MPLSLCFSTDCTRLLMAXDLCI表示的DLCI范围不得重叠。

We wish to thank Joan Cucchiara and Carlos Pignataro for their comments on this document.
我们谨感谢琼·库奇亚拉和卡洛斯·皮格纳塔罗对本文件的评论。
It is clear that these MIB modules are potentially useful for monitoring MPLS LSRs supporting LC-ATM and/or LC-FR. These MIBs 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，这些MIB模块对于监控支持LC-ATM和/或LC-FR的MPLS LSR可能很有用。这些MIB还可用于配置某些对象，任何可以配置的都可能被错误配置，从而导致潜在的灾难性后果。
There are a 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模块中定义了许多管理对象，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 MplsLcAtmStdInterfaceConfTable and mplsLcFrStdInterfaceConfTable collectively contain objects that may be used to provision MPLS LC or FR-enabled interfaces. Unauthorized access to objects in these tables could result in disruption of traffic on the network. This is especially true if traffic has been established over these interfaces. 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 that 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 MPLSLCATMSTDInterfaceConptable和MPLSLCRSTDInterfaceConptable共同包含可用于提供启用MPLS LC或FR的接口的对象。未经授权访问这些表中的对象可能会导致网络流量中断。如果在这些接口上建立了通信量，则尤其如此。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 MplsLcAtmStdInterfaceConfTable and mplsLcFrStdInterfaceConfTable collectively show the LC-ATM and/or LC-FR interfaces, their associated configurations, and their linkages to other MPLS-related configuration and/or performance statistics. Administrators not wishing to reveal
o MplsLcAtmStdInterfaceConfTable和MPLSLCFSTDInterfaceConfTable共同显示LC-ATM和/或LC-FR接口、它们的相关配置以及它们与其他MPLS相关配置和/或性能统计数据的链接。管理员不希望透露
this information should consider these objects sensitive/vulnerable and take precautions so they are not revealed.
这些信息应该考虑这些对象敏感/脆弱，并采取预防措施，使他们没有透露。
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。
As described in and as requested in the MPLS-TC-STD-MIB [RFC3811], MPLS-related standards track MIB modules should be rooted under the mplsStdMIB subtree. There are 2 MPLS MIB modules contained in this document; each of the following "IANA Considerations" subsections requested from IANA a new assignment under the mplsStdMIB subtree. New assignments can only be made via a Standards Action as specified in [RFC2434].
如MPLS-TC-STD-MIB[RFC3811]中所述和要求，MPLS相关标准轨道MIB模块应在MPLSTDMIB子树下扎根。本文件包含2个MPLS MIB模块；以下“IANA注意事项”小节要求IANA在MPLSTDMIB子树下进行新分配。新分配只能通过[RFC2434]中规定的标准行动进行。
The IANA has assigned { mplsStdMIB 9 } to the MPLS-LC-ATM-STD-MIB module specified in this document.
IANA已将{mplsStdMIB 9}分配给本文档中指定的MPLS-LC-ATM-STD-MIB模块。
The IANA has assigned { mplsStdMIB 10 } to the MPLS-LC-FR-STD-MIB module specified in this document.
IANA已将{mplsStdMIB 10}分配给本文档中指定的MPLS-LC-FR-STD-MIB模块。
