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.
このメモは、インターネットコミュニティのネットワーク管理プロトコルで使用するための管理情報ベース（MIB）の一部を定義します。特に、インターネットグループ管理プロトコル（IGMP）バージョン1 [RFC1112]、バージョン2 [RFC2236]、またはバージョン3 [RFC3376]およびマルチキャストリスナーディスカバリー（MLD）プロトコルバージョンバージョン1 [RFC2710]またはバージョン2 [RFC3810]。両方のプロトコルは、マルチキャストメンバーシップの発見機能を提供します。IGMPは、IPバージョン4クライアント、およびMLDにIPバージョン6クライアントに関係しています。このバージョンのMIBは、RFC 2933 [RFC2933]とRFC 3019 [RFC3019]の両方の廃止され、IGMPとMLDの両方の実装の一般的なインターフェイスを組み込み、マルチキャストクライアントの「ソースフィルタリング」を有効にするために変更を組み込みます。MIBは、それぞれに対して定義された関連する管理オブジェクトを備えたルーターとホストノードの両方を含みます。
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410].
現在のインターネット標準管理フレームワークを説明するドキュメントの詳細な概要については、RFC 3410 [RFC3410]のセクション7を参照してください。
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].
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].
このドキュメントのキーワード "MUST"、"MUST NOT"、"REQUIRED"、"SHALL"、"SHALL NOT"、"SHOULD"、"SHOULD NOT"、"RECOMMENDED"、"MAY"、および "OPTIONAL" は、RFC 2119 [RFC2119] で説明されているように解釈されるものとします。
This Multicast Group Membership Discovery (MGMD) MIB module contains eight tables:
このマルチキャストグループメンバーシップディスカバリー（MGMD）MIBモジュールには、8つのテーブルが含まれています。
1. the MGMD Host Interface Table, which contains one row for each interface on which IGMP or MLD is enabled on a host,
1. IGMPまたはMLDがホストで有効になっている各インターフェイスに1つの行を含むMGMDホストインターフェイステーブル、
2. the MGMD Router Interface Table, which contains one row for each interface on which MGMD is enabled on a router,
2. MGMDルーターインターフェイステーブルには、MGMDがルーターで有効になっている各インターフェイスに1つの行が含まれています。
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ホストキャッシュテーブルには、ホストに特定のインターフェイスにメンバーがいる各IPマルチキャストグループに1つの行が含まれています。
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ルーターキャッシュテーブルには、ルーター上に特定のインターフェイスにメンバーがいる各IPマルチキャストグループに1つの行が含まれています。
5. the reverse MGMD Host Table, which contains one row for each interface for which there are active multicast groups on a host,
5. ホストにアクティブなマルチキャストグループがある各インターフェイスに1つの行を含む逆MGMDホストテーブル、
6. the reverse MGMD Router Table, which contains one row for each interface for which there are active multicast groups on a router,
6. ルーターにアクティブなマルチキャストグループがある各インターフェイスに1つの行を含む逆MGMDルーターテーブル、
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テーブルには、インターフェイスのソースフィルターレコードの各エントリとホストのマルチキャストグループペアの1つの行が1つ含まれています。
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テーブルには、ルーター上のインターフェイスとマルチキャストグループペアのソースフィルターレコードの各エントリに1つの行が含まれています。
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 includes or excludes associated with each IP multicast group on each specific interface. This functionality is only supported in IGMPv3- and MLDv2-capable nodes.
すべてのテーブルは、名前と対応する説明で示されるようにルーターまたはホスト機能のいずれかを対象としていますが、両方の用語がデバイスに適用されるシナリオ、たとえばホストとしてマルチキャストグループに加わるルーターがあると予想されます。測定目的。ソースリストテーブルは、各特定のインターフェイスの各IPマルチキャストグループに関連付けられたソース固有の含まれるまたは除外を示すために、キャッシュテーブルの拡張機能を提供します。この機能は、IGMPV3-およびMLDV2対応ノードでのみサポートされています。
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テーブルに組み込まれているのは、RFC 4605 [RFC4605]に記載されているように、IGMPおよびMLDプロキシデバイスの管理のためのオブジェクトです。プロキシデバイスは、完全なマルチキャストルーティングプロトコルを実行する必要がない単純なトポロジで使用できます。プロキシデバイスは、IGMPまたはMLDグループメンバーシップアクティビティに基づいて転送決定を行うことができます。
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は、ネットワークインターフェイスサブレイヤーの一般的なオブジェクトを記述するMIBであるRFC 2863 [RFC2863]で定義されているように、インターフェイスインデックスおよびインターフェイスインデクセルゼロオブジェクトを参照しています。
Extensive references to the InetAddress and InetAddressType objects are made as defined in RFC 4001 [RFC4001].
InetAddressおよびInetAddressTypeオブジェクトへの広範な参照は、RFC 4001 [RFC4001]で定義されているように作成されています。

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:
このMIBモジュールには、読み取りワイトおよび/またはread-Createの最大アクセス句を備えた管理オブジェクトが多数あります。このようなオブジェクトは、一部のネットワーク環境で敏感または脆弱と見なされる場合があります。適切な保護なしの非セキュア環境でのセット操作のサポートは、ネットワーク操作に悪影響を与える可能性があります。これらはテーブルとオブジェクトであり、その感度/脆弱性です。
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は、mgmdRouterInterfaceStatusとmgmdRouterInterfaceQueryIntervalの2つの値への読み取りアクセスを提供します。MGMDROUTERINTERFACESTATATUSは、特定のルーターインターフェイスでマルチキャストサポートを有効または無効にする機能をリモートユーザーに提示するため、サービス拒否の脆弱性が重要です。mgmdRouterInterfaceQueryIntervalは、ホストクエリパケットが送信される周波数を制御し、脆弱性は少なくなりますが、安全なアクセス制御が必要です。
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は、読み取りオブジェクトへのアクセスも提供します。mgmdRouterInterfaceVersionは、インターフェイスのプロトコルの適合性を制御するため、潜在的なサービス拒否の脆弱性です。mgmdRouterInterfaceQueryMaxResponseTime、mgmdRouterInterfaceRobustness、およびmgmdRouterInterfaceLastMemberQueryIntervalはすべて、ホストクエリパケットの特性を制御するためのチューニングパラメーターです。これらのオブジェクトの妥協は、ローカルマルチキャスト通信を破壊する可能性があります。
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は、読み取りされたオブジェクトであるMgmdhostinterfaceversion3 robustnessを提供し、インターフェイスの堅牢性をパケット損失に制御します。パケットの損失に直面して堅牢性を無効にすると、ホストのサービス拒否を引き起こす可能性があります。ただし、一般に、これは低リスクを示しています。
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以前のSNMPバージョンには、適切なセキュリティは含まれていませんでした。ネットワーク自体が（たとえばIPSECを使用して）安全である場合でも、それでもセキュアネットワーク上の誰がアクセス/セット/セット（読み取り/変更/作成/削除/削除）を制御することはできません。MIBモジュール。
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).
実装者は、SNMPV3暗号化メカニズム（認証とプライバシー用）の完全なサポートを含む、SNMPV3フレームワーク（[RFC3410]、セクション8を参照）で提供されるセキュリティ機能を考慮することをお勧めします。
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.
さらに、SNMPV3より前のSNMPバージョンの展開は推奨されません。代わりに、SNMPV3を展開し、暗号化セキュリティを有効にすることをお勧めします。その場合、このMIBモジュールのインスタンスへのアクセスを提供するSNMPエンティティが、実際に取得または設定する正当な権利を持つプリンシパル（ユーザー）にのみオブジェクトにアクセスできるように適切に構成されていることを保証するのは、顧客/オペレーターの責任です（変更を変更します（変更）/作成/削除）それら。
