This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes objects used for managing the Internet Group Management Protocol (IGMP) version 1 [RFC1112], version 2 [RFC2236], or version 3 [RFC3376] and the Multicast Listener Discovery (MLD) protocol version 1 [RFC2710] or version 2 [RFC3810]. Both protocols provide multicast membership discovery capability. IGMP pertains to IP version 4 clients, and MLD to IP version 6 clients. This version of the MIB obsoletes both RFC 2933 [RFC2933] and RFC 3019 [RFC3019], incorporating a generic interface for both IGMP and MLD implementations and incorporating changes to enable "source filtering" in multicast clients. The MIB encompasses both router and host nodes with relevant management objects defined for each.
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。特别地，它描述了用于管理因特网组管理协议（IGMP）版本1[RFC1112]、版本2[RFC2236]或版本3[RFC3376]和多播侦听器发现（MLD）协议版本1[RFC2710]或版本2[RFC3810]的对象。这两种协议都提供了多播成员发现功能。IGMP适用于IP版本4客户端，MLD适用于IP版本6客户端。此版本的MIB淘汰了RFC 2933[RFC2933]和RFC 3019[RFC3019]，为IGMP和MLD实现合并了通用接口，并合并了在多播客户端中启用“源过滤”的更改。MIB包含路由器和主机节点，并为每个节点定义了相关的管理对象。
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。
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 [RFC2119].
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[RFC2119]中所述进行解释。
This Multicast Group Membership Discovery (MGMD) MIB module contains eight tables:
此多播组成员身份发现（MGMD）MIB模块包含八个表：
1. the MGMD Host Interface Table, which contains one row for each interface on which IGMP or MLD is enabled on a host,
1. MGMD主机接口表，其中包含主机上启用IGMP或MLD的每个接口的一行，
2. the MGMD Router Interface Table, which contains one row for each interface on which MGMD is enabled on a router,
2. MGMD路由器接口表，其中包含路由器上启用MGMD的每个接口的一行，
3. the MGMD Host Cache Table, which contains one row for each IP multicast group for which there are members on a particular interface on a host,
3. MGMD主机缓存表，其中包含每个IP多播组的一行，主机上的特定接口上有成员，
4. the MGMD Router Cache Table, which contains one row for each IP multicast group for which there are members on a particular interface on a router,
4. MGMD路由器缓存表，其中包含每个IP多播组的一行，每个IP多播组的成员位于路由器上的特定接口上，
5. the reverse MGMD Host Table, which contains one row for each interface for which there are active multicast groups on a host,
5. 反向MGMD主机表，其中包含主机上有活动多播组的每个接口的一行，
6. the reverse MGMD Router Table, which contains one row for each interface for which there are active multicast groups on a router,
6. 反向MGMD路由器表，其中包含路由器上有活动多播组的每个接口的一行，
7. the MGMD HostSrcList Table, which contains one row for each entry in the source filter record for an interface and multicast group pair on a host, and
7. MGMD HostSrcList表，该表包含主机上接口和多播组对的源筛选器记录中每个条目的一行，以及
8. the MGMD RouterSrcList Table, which contains one row for each entry in the source filter record for an interface and multicast group pair on a router.
8. MGMD RouterSrcList表，该表包含路由器上接口和多播组对的源筛选器记录中每个条目的一行。
All tables are intended for EITHER router OR host functionality as indicated by the name and corresponding description, although it is anticipated that there will be scenarios where both terms might apply to a device, e.g., a router that joins a multicast group also as a host for measurement purposes. The source list tables provide an extension to the cache tables to indicate the source-specific
所有表都用于路由器或主机功能，如名称和相应的描述所示，但预计会有两个术语都适用于设备的情况，例如，出于测量目的加入多播组的路由器也作为主机。源列表表提供缓存表的扩展，以指示特定于源的
includes or excludes associated with each IP multicast group on each specific interface. This functionality is only supported in IGMPv3- and MLDv2-capable nodes.
包括或排除与每个特定接口上的每个IP多播组关联的内容。此功能仅在支持IGMPv3和MLDv2的节点中受支持。
Incorporated within the MGMD MIB tables are objects for the management of IGMP and MLD proxy devices as described in RFC 4605 [RFC4605]. Proxy devices can be used in simple topologies where it is not necessary to run a full multicast routing protocol. A proxy device can make forwarding decisions based on IGMP or MLD group membership activity.
MGMD MIB表中包含用于管理IGMP和MLD代理设备的对象，如RFC 4605[RFC4605]中所述。代理设备可以用在简单的拓扑中，在这种拓扑中不需要运行完整的多播路由协议。代理设备可以根据IGMP或MLD组成员资格活动做出转发决策。
The MIB references InterfaceIndex and InterfaceIndexOrZero objects as defined in RFC 2863 [RFC2863], the MIB that describes generic objects for network interface sub-layers.
MIB引用RFC 2863[RFC2863]中定义的InterfaceIndex和InterfaceIndexOrZero对象，该MIB描述网络接口子层的通用对象。
Extensive references to the InetAddress and InetAddressType objects are made as defined in RFC 4001 [RFC4001].
根据RFC 4001[RFC4001]中的定义，对InetAddress和InetAddressType对象进行了大量引用。

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 mgmdRouterInterfaceTable provides read-create access to 2 values: the mgmdRouterInterfaceStatus and the mgmdRouterInterfaceQueryInterval. The mgmdRouterInterfaceStatus presents a remote user with the ability to enable or disable multicast support on a given router interface, and therefore presents a significant denial-of-service vulnerability. The mgmdRouterInterfaceQueryInterval controls the frequency with which host-query packets are sent, providing less of a vulnerability, but still requiring secure access control.
o mgmdRouterInterfaceTable提供对两个值的读-创建访问：mgmdRouterInterfaceStatus和mgmdRouterInterfaceQueryInterval。mgmdRouterInterfaceStatus使远程用户能够在给定的路由器接口上启用或禁用多播支持，因此存在严重的拒绝服务漏洞。mgmdRouterInterfaceQueryInterval控制主机查询数据包的发送频率，提供的漏洞较少，但仍需要安全访问控制。
o The mgmdRouterCacheTable also provides access to read-create objects. The mgmdRouterInterfaceVersion controls the protocol conformance of an interface, and is therefore a potential denial-of-service vulnerability. The mgmdRouterInterfaceQueryMaxResponseTime, the mgmdRouterInterfaceRobustness, and the mgmdRouterInterfaceLastMemberQueryInterval are all tuning parameters to control the characteristic of the host-query packets. Compromise of these objects can potentially be disruptive to local multicast communication.
o mgmdRouterCacheTable还提供对读取和创建对象的访问。mgmdRouterInterfaceVersion控制接口的协议一致性，因此是一个潜在的拒绝服务漏洞。mgmdRouterInterfaceQueryMaxResponseTime、MGMDRouterInterfaceRobustibility和mgmdRouterInterfaceLastMemberQueryInterval都是用于控制主机查询数据包特性的调优参数。这些对象的泄露可能会破坏本地多播通信。
o The mgmdHostInterfaceTable provides a read-create object, the mgmdHostInterfaceVersion3Robustness, which controls the robustness of the interface to packet loss. Disabling robustness in the face of packet loss could cause denial of service to hosts; however, in general this presents a low risk.
o mgmdHostInterfaceTable提供一个读创建对象，即MGMDHostInterfaceVersion3Robustibility，它控制接口对数据包丢失的鲁棒性。在数据包丢失时禁用健壮性可能会导致主机拒绝服务；然而，一般来说，这是一个低风险。
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。
This MIB introduces a new term to refer to two existing multicast protocols: Multicast Group Membership Discovery. It encompasses both the IPv4 Multicast discovery protocol, IGMP, and the IPv6 Multicast discovery protocol, MLD, as defined in RFCs 2933 [RFC2933] and 3019 [RFC3019], respectively.
这个MIB引入了一个新术语来指代两个现有的多播协议：多播组成员发现。它包括IPv4多播发现协议IGMP和IPv6多播发现协议MLD，分别在RFCs 2933[RFC2933]和3019[RFC3019]中定义。
