This memo defines a portion of the MIB for use with network management protocols in the Internet community. In particular, it describes managed objects to configure and/or monitor Bidirectional Forwarding Detection for [RFC5880], [RFC5881], [RFC5883], and [RFC7130], BFD versions 0 and/or 1, on devices supporting this feature.
此备忘录定义了MIB的一部分，用于Internet社区中的网络管理协议。特别是，它描述了在支持此功能的设备上配置和/或监视[RFC5880]、[RFC5881]、[RFC5883]和[RFC7130]、BFD版本0和/或1的双向转发检测的托管对象。
This memo does not define a compliance requirement for a system that only implements BFD version 0. This is a reflection of a considered and deliberate decision by the BFD WG because the BFD version 0 protocol is primarily of historical interest by comparison to the widespread deployment of the BFD version 1 protocol.
此备忘录未定义仅实现BFD版本0的系统的合规性要求。这反映了BFD工作组经过深思熟虑的决定，因为与广泛部署BFD版本1协议相比，BFD版本0协议主要具有历史意义。
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,
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所述，
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580].
RFC 2578[RFC2578]，标准58，RFC 2579[RFC2579]和标准58，RFC 2580[RFC2580]。
As with all MIB modules, an attempt to SET or CREATE an object to a value that is not supported by the implementation will result in a failure using a return code that indicates that the value is not supported.
与所有MIB模块一样，尝试将对象设置或创建为实现不支持的值将导致失败，返回代码指示不支持该值。
This document adopts the definitions, acronyms, and mechanisms described in [RFC5880], [RFC5881], [RFC5883], and [RFC7130]. Unless otherwise stated, the mechanisms described therein will not be redescribed here.
本文件采用[RFC5880]、[RFC5881]、[RFC5883]和[RFC7130]中所述的定义、首字母缩略词和机制。除非另有说明，此处不会重新描述其中描述的机制。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "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”、“建议”、“不建议”、“可”和“可选”应按照BCP 14、RFC 2119[RFC2119]中的说明进行解释。
This section describes objects pertaining to BFD. The MIB objects are derived from [RFC5880], [RFC5881], [RFC5883], and [RFC7130], and also include textual conventions defined in [RFC7330].
本节介绍与BFD相关的对象。MIB对象派生自[RFC5880]、[RFC5881]、[RFC5883]和[RFC7130]，还包括[RFC7330]中定义的文本约定。
The General Variables are used to identify parameters that are global to the BFD process.
通用变量用于识别BFD过程的全局参数。
The session table is used to identify a BFD session between a pair of nodes.
会话表用于标识一对节点之间的BFD会话。
The session performance table is used for collecting BFD performance counters on a per-session basis. This table is an AUGMENT to the bfdSessionTable.
会话性能表用于收集每个会话的BFD性能计数器。此表是对BFDSession表的扩充。
The BFD Session Discriminator Mapping Table provides a mapping between a local discriminator value to the associated BFD session found in the bfdSessionTable.
BFD会话鉴别器映射表提供本地鉴别器值与在BFDSession表中找到的关联BFD会话之间的映射。
Given bfdSessInterface, bfdSessSrcAddrType, bfdSessSrcAddr, bfdSessDstAddrType, and bfdSessSrcAddrType, the BFD Session IP Mapping Table maps to an associated BFD session found in the bfdSessionTable. This table SHOULD contain those BFD sessions that are of type "IP".
给定bfdSessInterface、bfdSessSrcAddrType、bfdSessSrcAddr、BFDSessDsAddrType和bfdSessSrcAddrType，BFD会话IP映射表将映射到在BFDSSession表中找到的关联BFD会话。此表应包含类型为“IP”的BFD会话。
This MIB module makes references to the following documents: [RFC2578], [RFC2579], [RFC2580], [RFC2863], [RFC3289], [RFC3413], [RFC5082], [RFC5880], and [RFC5881].

As BFD may be tied into the stability of the network infrastructure (such as routing protocols), the effects of an attack on a BFD session may be very serious. This ultimately has denial-of-service effects, as links may be declared to be down (or falsely declared to be up.) As such, improper manipulation of the objects represented by this MIB may result in denial of service to a large number of end users.
由于BFD可能与网络基础设施（如路由协议）的稳定性有关，因此攻击BFD会话的影响可能非常严重。这最终会产生拒绝服务的影响，因为链接可能会被声明为关闭（或错误地声明为打开）。因此，对此MIB表示的对象的不当操作可能会导致拒绝服务给大量最终用户。
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 bfdAdminStatus -- Improper change of bfdAdminStatus, to disabled(2), adminDown(3), or down(4), can cause significant disruption of the connectivity to those portions of the Internet reached via all the applicable remote BFD peers.
o bfdAdminStatus——不正确地将bfdAdminStatus更改为disabled（2）、adminDown（3）或down（4），可能会导致通过所有适用的远程BFD对等点连接到Internet的那些部分的连接严重中断。
o bfdSessAdminStatus -- Improper change of bfdSessAdminStatus, to disabled(2), adminDown(3), or down(4), can cause significant disruption of the connectivity to those portions of the Internet reached via all the applicable remote BFD peers.
o bfdSessAdminStatus--将bfdSessAdminStatus不正确地更改为disabled（2）、adminDown（3）或down（4），可能会导致通过所有适用的远程BFD对等点连接到Internet的那些部分的连接严重中断。
o bfdSessDesiredMinTxInterval, bfdSessReqMinRxInterval, bfdSessReqMinEchoRxInterval, bfdSessDetectMult -- Improper change of this object can cause connections to be disrupted for extremely long time periods when otherwise they would be restored in a relatively short period of time.
o bfdSessDesiredMinTxInterval、bfdSessReqMinRxInterval、bfdSessReqMinEchoRxInterval、BFDSessDetectModule--此对象的不正确更改可能会导致连接中断很长时间，否则将在相对较短的时间内恢复连接。
o Some management objects define the BFD session whilst other management objects define the parameter of the BFD session. It is particularly important to control the support for SET access to those management objects that define the BFD session, as changes to them can be disruptive. Implementation SHOULD NOT allow changes to following management objects when bfdSessState is up(4):
o 一些管理对象定义BFD会话，而其他管理对象定义BFD会话的参数。控制对定义BFD会话的管理对象的集合访问的支持尤其重要，因为对它们的更改可能会造成中断。当bfdSessState启动（4）时，实现不应允许更改以下管理对象：
* bfdSessVersionNumber
* bfdSessVersionNumber
* bfdSessType
* bfdesstype
* bfdSessDestinationUdpPort
* BFDSessDestinationUpport
* bfdSessMultipointFlag
* bfdSessMultipointFlag
* bfdSessInterface
* bfdessInterface
* bfdSessSrcAddrType
* bfdesssrcadrtype
* bfdSessSrcAddr
* bfdesssrcacddr
* bfdSessDstAddrType
* bfdessdstaddrtype
* bfdSessDstAddr
* bfdessdstaddr
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. 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.
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。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。
o The bfdSessTable may be used to directly configure BFD sessions. The bfdSessMapTable can be used indirectly in the same way. Unauthorized access to objects in this table could result in disruption of traffic on the network. This is especially true if an unauthorized user configures enough tables to invoke a denial-of-service attack on the device where they are configured, or on a remote device where the sessions terminate.
o bfdSessTable可用于直接配置BFD会话。BFDSESMAPTABLE也可以以同样的方式间接使用。未经授权访问此表中的对象可能会导致网络流量中断。如果未经授权的用户配置了足够多的表，以便在配置表的设备或会话终止的远程设备上调用拒绝服务攻击，则尤其如此。
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 bfdSessPerfTable allows access to the performance characteristics of BFD sessions. Network administrators not wishing to show this information should consider this table sensitive.
o bfdSessPerfTable允许访问BFD会话的性能特征。不希望显示此信息的网络管理员应考虑此表敏感。
The bfdSessAuthenticationType, bfdSessAuthenticationKeyID, and bfdSessAuthenticationKey objects hold security methods and associated security keys of BFD sessions. These objects are highly sensitive. In order to prevent this sensitive information from being improperly accessed, implementers SHOULD disallow access to these objects.
bfdSessAuthenticationType、bfdSessAuthenticationKeyID和bfdSessAuthenticationKey对象保存BFD会话的安全方法和关联的安全密钥。这些物体高度敏感。为了防止不正确地访问这些敏感信息，实现者应该禁止访问这些对象。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec),
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），
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.
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]), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy).
建议实施者考虑SNMPv3框架提供的安全特性（参见[RCF310]），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 module in this document uses the following IANA-assigned OBJECT IDENTIFIER value recorded in the "SMI Network Management MGMT Codes" registry:
本文档中的MIB模块使用“SMI网络管理代码”注册表中记录的以下IANA分配对象标识符值：
Descriptor OBJECT IDENTIFIER value

bfdMIB { mib-2 222 }

---------- -----------------------
