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 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].

現在のインターネット標準管理フレームワークを説明してい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。管理対象オブジェクトは、管理情報ベースまたはMIBと呼ばれる仮想情報ストアを介してアクセスされます。 MIBオブジェクトには、通常、簡易ネットワーク管理プロトコル(SNMP)を介してアクセスします。 MIB内のオブジェクトは、管理情報の構造(SMI)で定義されたメカニズムを使用して定義されます。このメモは、SMIv2に準拠するMIBモジュールを指定します。これは、STD 58、RFC 2578 [RFC2578]で説明されています。 STD 58、RFC 2579 [RFC2579];およびSTD 58、RFC 2580 [RFC2580]。

2.2.1. はじめに

The EPON standard, as defined in [802.3ah], defines the physical media (Layer 1) and media access (Layer 2) of the EPON interface. The EPON is a variant of the Gigabit Ethernet protocol for the Optical Access. The Optical Access topology is based on passive optical splitting topology. The link of a Passive Optical Network (PON) is based on a single, shared optical fiber with passive optical splitters dividing the single fiber into separate subscribers.

[802.3ah]で定義されているEPON標準は、EPONインターフェースの物理メディア(レイヤー1)とメディアアクセス(レイヤー2)を定義しています。 EPONは、光アクセス用のギガビットイーサネットプロトコルの一種です。光アクセストポロジは、パッシブ光分割トポロジに基づいています。パッシブ光ネットワーク(PON)のリンクは、単一の共有光ファイバーと、単一のファイバーを別々の加入者に分割するパッシブ光スプリッターに基づいています。

2.2.2. Principles of Operation
2.2.2. 動作原理

The specification of the EPON interface is based on the specification of the gigabit Ethernet interface as described in [802.3], clauses 35 and 36. The Ethernet MAC is working in gigabit rate. The media interface to the MAC is through the GMII interface, as described in clause 35, and the PCS layer is based on the gigabit Ethernet PCS as described in clause 36. The special EPON layers are added to the Ethernet layering in the following places:

EPONインターフェイスの仕様は、[802.3]の35および36節で説明されているギガビットイーサネットインターフェイスの仕様に基づいています。イーサネットMACはギガビットレートで動作しています。 MACへのメディアインターフェイスは、35節で説明するようにGMIIインターフェイスを経由し、PCSレイヤーは36節で説明するようにギガビットイーサネットPCSに基づいています。特別なEPONレイヤーは、次の場所でイーサネットレイヤーに追加されます。

The MPCP is placed in the MAC control layer, providing the EPON control protocol. The Emulation layer, located at the RS (Reconciliation Sublayer), creates virtual private path to each ONU. The FEC layer is located between the PCS and PMA layers, enhancing reach and split performance of the optical link.

MPCPはMAC制御層に配置され、EPON制御プロトコルを提供します。 RS(Reconciliation Sublayer)にあるエミュレーションレイヤーは、各ONUへの仮想プライベートパスを作成します。 FECレイヤーはPCSレイヤーとPMAレイヤーの間にあり、光リンクの到達距離とスプリットパフォーマンスを向上させます。

2.2.3. The Physical Media
2.2.3. 物理メディア

The physical link is a fiber optical link. The OLT and ONUs are connected through passive optical splitters. Downlink denotes the transmission from the OLT to the ONUs. Uplink denotes the transmission from the ONUs to the OLT. Uplink and downlink are multiplexed using separated wavelengths on the same fiber. The downlink is a broadcast medium where the OLT transmits the data to all ONUs. The uplink is a shared transmission medium for all of the ONUs. The uplink access is based on time division multiplexing (TDM) and the management of the TDM media access is defined by the Multi- Point Control Protocol (MPCP). The MPCP is a control protocol based on an inband packet messaging. The OLT sends control messages (GATE messages) allowing ONUs to transmit, defining when the transmission occurs and what is its duration. These messages define the transmission order and the amount of BW for each ONU. A scheduling algorithm at the OLT, which is not defined in the [802.3ah], is responsible for allocating the BW and controlling the delay of each ONU according to its SLA.

物理リンクは光ファイバーリンクです。 OLTとONUは、パッシブ光スプリッターを介して接続されます。ダウンリンクは、OLTからONUへの送信を示します。アップリンクは、ONUからOLTへの送信を示します。アップリンクとダウンリンクは、同じファイバー上で別々の波長を使用して多重化されます。ダウンリンクは、OLTがすべてのONUにデータを送信するブロードキャストメディアです。アップリンクは、すべてのONUの共有伝送媒体です。アップリンクアクセスは時分割多重化(TDM)に基づいており、TDMメディアアクセスの管理はマルチポイントコントロールプロトコル(MPCP)によって定義されます。 MPCPは、インバンドパケットメッセージングに基づく制御プロトコルです。 OLTは、ONUが送信できるようにする制御メッセージ(GATEメッセージ)を送信し、送信がいつ発生するか、およびその期間を定義します。これらのメッセージは、各ONUの送信順序と帯域幅の量を定義します。 [802.3ah]で定義されていない、OLTのスケジューリングアルゴリズムは、BWを割り当て、そのSLAに従って各ONUの遅延を制御します。

2.2.4. PMD Specifications
2.2.4. PMD仕様

PMD specifications select the same optical wavelength plan as the [ITU-T.G.983]. The transceivers are derivatives of existing Ethernet optical transceivers, with dual wavelength on a single fiber, and extended burst capabilities for the uplink. The uplink burst capability is the burst transmission functionality for the ONUs and burst reception functionality for the OLT. The [802.3ah] selected very relaxed burst parameters to reduce the device cost of EPON products.

PMD仕様は、[ITU-T.G.983]と同じ光波長プランを選択します。トランシーバーは、既存のイーサネット光トランシーバーの派生物であり、単一のファイバーにデュアル波長があり、アップリンクの拡張バースト機能があります。アップリンクバースト機能は、ONUのバースト送信機能とOLTのバースト受信機能です。 [802.3ah]は、EPON製品のデバイスコストを削減するために、非常に緩和されたバーストパラメータを選択しました。

2.2.5. Point-to-Point Emulation
2.2.5. ポイントツーポイントエミュレーション

The downstream is a broadcast link, which means that the OLT transmission is shared for all ONUs. The sharing of the transmission of the OLT has some negative privacy aspects and should be limited to broadcast traffic in nature only. The traffic dedicated to each ONU should not be shared. The solution provided by [802.3ah] is to partition the EPON link, in a virtual manner, between the ONUs. Each ONU has a dedicated virtual link to the OLT. The [802.3ah] also defines an additional link for broadcast transmission. The medium becomes an aggregation of point-to-point tunnels. The OLT cannot preserve its EPON interface as a single interface connected to N devices (following the properties of the physical interface). The EPON interface of the OLT is partitioned into separate virtual interfaces; an interface for each virtual link. Hence, the OLT behaves like a device with N virtual ports (and an additional port for the broadcast transmission). The additional single-copy-broadcast channel (tagged as all one LLID) is added to allow the broadcast transmission within a single copy to all ONUs, preserving the inherent advantage of BW efficiency of the PON shared media. The ONUs filter the downlink traffic that is not intended for their reception, according to the virtual link marking. An LLID tag is attached at the preamble of the Ethernet packet denoting the virtual link. The LLID marks the destination port in the downstream and source port in the upstream.

ダウンストリームはブロードキャストリンクです。つまり、OLT送信はすべてのONUで共有されます。 OLTの送信の共有には、いくつかの否定的なプライバシーの側面があり、ブロードキャストトラフィックのみに制限する必要があります。各ONU専用のトラフィックは共有しないでください。 [802.3ah]によって提供されるソリューションは、ONU間でEPONリンクを仮想的に分割することです。各ONUには、OLTへの専用仮想リンクがあります。 [802.3ah]は、ブロードキャスト送信用の追加リンクも定義しています。メディアはポイントツーポイントトンネルの集合体になります。 OLTは、そのEPONインターフェイスを、(物理インターフェイスのプロパティに従って)Nデバイスに接続された単一のインターフェイスとして保持できません。 OLTのEPONインターフェイスは、個別の仮想インターフェイスに分割されます。各仮想リンクのインターフェース。したがって、OLTはN個の仮想ポート(およびブロードキャスト送信用の追加ポート)を備えたデバイスのように動作します。追加の単一コピーブロードキャストチャネル(すべて1つのLLIDとしてタグ付け)が追加され、すべてのONUへの単一コピー内のブロードキャスト送信が可能になり、PON共有メディアのBW効率の固有の利点を維持します。 ONUは、仮想リンクマーキングに従って、受信を目的としていないダウンリンクトラフィックをフィルタリングします。 LLIDタグは、仮想リンクを示すイーサネットパケットのプリアンブルに添付されます。 LLIDは、ダウンストリームの宛先ポートとアップストリームの送信元ポートをマークします。

The virtual links concept is also used to avoid a violation of the [802.1d] bridging rules for peer-to-peer traffic in the PON. Peer-to-peer traffic is traffic between ONUs in the same PON. The OLT cannot preserve the EPON interface as a single interface, connected to N devices, and allow traffic between these devices without violating the bridging rules. The source address and destination address of the peer-to-peer traffic are behind the same port and therefore the traffic should be discarded. The separation of the ONUs into virtual links solves this issue. The OLT has N virtual ports for the single physical EPON port. A bridge sees a single MAC Client for every link pair.

仮想リンクの概念は、PONでのピアツーピアトラフィックの[802.1d]ブリッジングルールの違反を回避するためにも使用されます。ピアツーピアトラフィックは、同じPON内のONU間のトラフィックです。 OLTは、Nデバイスに接続されたEPONインターフェイスを単一のインターフェイスとして保持できず、ブリッジングルールに違反せずにこれらのデバイス間のトラフィックを許可できません。ピアツーピアトラフィックの送信元アドレスと宛先アドレスが同じポートの背後にあるため、トラフィックを破棄する必要があります。 ONUを仮想リンクに分離すると、この問題が解決します。 OLTには、単一の物理EPONポート用のN個の仮想ポートがあります。ブリッジは、リンクペアごとに1つのMACクライアントを認識します。

The private paths concept solves the networking problems and provides subscriber isolation.

プライベートパスの概念は、ネットワークの問題を解決し、加入者の分離を提供します。

As the tunneling is only a virtual tunneling, there is a single physical interface and a single physical layer for the device so that some attributes are shared. For example, the interface has a single local MAC address.

トンネリングは仮想トンネリングにすぎないため、デバイスには単一の物理インターフェイスと単一の物理層があり、一部の属性が共有されます。たとえば、インターフェイスには単一のローカルMACアドレスがあります。

The virtual tunneling for an OLT with 3 ONUs is illustrated in the following diagram.

3つのONUを持つOLTの仮想トンネリングを次の図に示します。

2.2.6. Principles of the MPCP
2.2.6. MPCPの原則

The EPON standard defines a media access control of an optical Access network. The Access network has some substantial differences from the legacy LAN for which the Ethernet was designed. The differences lie mainly in the provisioning of the network. An Access network is an administrated environment, with an operator providing the service and subscribers consuming it. The operator is controlling the network and managing its traffic. For instance, BW is controlled and subscribers are billed for services. The MPCP protocol divides the Ethernet interfaces into two unequal types of network units. The first interface is an OLT interface, which is a server unit, controlling the network. The second interface is an ONU interface, which is a client unit, participating in the network.

EPON規格は、光アクセスネットワークのメディアアクセス制御を定義しています。アクセスネットワークは、イーサネットが設計されたレガシーLANとは大幅に異なります。違いは主にネットワークのプロビジョニングにあります。アクセスネットワークは管理された環境であり、オペレーターがサービスを提供し、サブスクライバーがサービスを利用します。オペレーターはネットワークを制御し、そのトラフィックを管理しています。たとえば、BWが制御され、加入者はサービスに対して課金されます。 MPCPプロトコルは、イーサネットインターフェイスを2つの等しくないタイプのネットワークユニットに分割します。最初のインターフェイスは、ネットワークを制御するサーバーユニットであるOLTインターフェイスです。 2番目のインターフェイスは、ネットワークに参加しているクライアントユニットであるONUインターフェイスです。

The OLT, which is the server unit, manages the network. The MPCP controls the TDM transmission of the uplink. The MPCP is implemented at the MAC control layer and the MPCP messages are MAC control messages using the 0x8808 Ethertype. These messages are not forwarded out of the MAC.

サーバーユニットであるOLTはネットワークを管理します。 MPCPは、アップリンクのTDM送信を制御します。 MPCPはMAC制御層で実装され、MPCPメッセージは0x8808 Ethertypeを使用するMAC制御メッセージです。これらのメッセージはMACから転送されません。

A concept of time must exist in the protocol in order to schedule the uplink transmission. A timestamp, which is set by the OLT and synchronized between the network units, is passed through the MPCP messages. The timestamp is also used to measure the RTT of each ONU. RTT is compensated by the OLT in the generation of the grants for the uplink transmission. The difference of incoming timestamp to local time allows the OLT to calculate the RTT. RTT compensation is needed as the RTT in an Access network can have a significant value. The standard allows the network to reach a 20 km distance, which is equivalent to a 200 usec RTT (25 Kbytes of data).

アップリンク送信をスケジュールするには、プロトコルに時間の概念が存在する必要があります。 OLTによって設定され、ネットワークユニット間で同期されるタイムスタンプは、MPCPメッセージを介して渡されます。タイムスタンプは、各ONUのRTTを測定するためにも使用されます。 RTTは、アップリンク送信の許可の生成においてOLTによって補償されます。受信タイムスタンプと現地時間の違いにより、OLTはRTTを計算できます。アクセスネットワークのRTTには大きな価値があるため、RTT補償が必要です。この規格により、ネットワークは20 kmの距離に到達できます。これは200 usec RTT(25 Kバイトのデータ)に相当します。

The TDM control is done using GATE messages. These messages define, for each ONU, the time for transmission and the length of transmission. The RTT is reduced from the transmission time in the GATE message to shift the transmission time of the ONU in the opposite direction.

TDM制御は、GATEメッセージを使用して行われます。これらのメッセージは、ONUごとに、送信時間と送信の長さを定義します。 RTTは、GATEメッセージの送信時間から短縮され、ONUの送信時間を反対方向にシフトします。

A scheduling algorithm at the OLT, which is not defined in the [802.3ah], is responsible for dividing the BW and controlling the transmission delay of each ONU according to its SLA. The MPCP defines a closed loop operation in order for this algorithm to be efficient. The MPCP allows the ONUs to report on the amount of BW they require for transmission using a special REPORT message. This allows allocating BW to an ONU only when requested, relying on the statistical burst property of the traffic, and allowing different peak BW for different ONUs at different times; hence, allowing oversubscription of the BW. The REPORT message reports the amount of data waiting in the ONU queues.

[802.3ah]で定義されていないOLTのスケジューリングアルゴリズムは、BWを分割し、そのSLAに従って各ONUの伝送遅延を制御する役割を果たします。このアルゴリズムを効率的にするために、MPCPは閉ループ操作を定義しています。 MPCPにより、ONUは、特別なREPORTメッセージを使用して、送信に必要なBWの量を報告できます。これにより、要求された場合にのみBWをONUに割り当て、トラフィックの統計バーストプロパティに依存し、異なるONUに対して異なる時間に異なるピークBWを許可できます。したがって、BWのオーバーサブスクリプションを許可します。 REPORTメッセージは、ONUキューで待機しているデータの量を報告します。

In addition, the MPCP defines a protocol of auto-discovery and registration of ONUs.

さらに、MPCPは、自動検出およびONUの登録のプロトコルを定義します。

The registration process is defined in the diagram below:

登録プロセスは、以下の図で定義されています。

      OLT                                          ONU

       |                                            |
        

A new ONU requests to register (sends a REG_REQUEST message) in a special discovery grant, allocated for that by the OLT. During that time, more than one ONU might try to register. A collision in transmission might occur, as the RTT of the new ONUs is not yet known. A random backoff mechanism of the transmission is used to schedule the following registration requests to avoid these collisions. When the OLT receives a REG_REQUEST message of an ONU and approves this ONU, then it sends a REGISTER message to this ONU defining its LLID. From that point, the ONU transmission is scheduled by its LLID, knowing the RTT, and no collision can occur. The ONU replies with a REGISTER_ACK message and the registration process of the MPCP ends. Higher layer protocols may be needed to authenticate the ONU and allow it to participate in the network.

新しいONUは、OLTによって割り当てられた特別なディスカバリー許可に登録する(REG_REQUESTメッセージを送信する)ことを要求します。その間、複数のONUが登録を試みる場合があります。新しいONUのRTTがまだわかっていないため、送信の衝突が発生する可能性があります。送信のランダムバックオフメカニズムを使用して、これらの衝突を回避するために次の登録要求をスケジュールします。 OLTがONUのREG_REQUESTメッセージを受信し、このONUを承認すると、LLIDを定義するREGISTERメッセージをこのONUに送信します。その時点から、ONU送信は、RTTを認識しているLLIDによってスケジュールされ、衝突は発生しません。 ONUがREGISTER_ACKメッセージで応答し、MPCPの登録プロセスが終了します。 ONUを認証してネットワークに参加させるには、上位層のプロトコルが必要になる場合があります。

2.2.7. Forward Error Correction (FEC)
2.2.7. 前方誤り訂正(FEC)

The FEC is defined to enhance the link budget of the PON. As each splitter attenuates the optical signal, the number of the splits and the distance are limited by the link budget. Hence an FEC that improves the link budget has a benefit. The FEC code used is the RS(239,255,8), similar to the FEC code in [ITU-T.G.975], improving the BER from 1E-4 to 1E-12.

FECは、PONのリンクバジェットを強化するために定義されます。各スプリッタは光信号を減衰させるため、スプリットの数と距離はリンクバジェットによって制限されます。したがって、リンクバジェットを改善するFECには利点があります。使用されるFECコードは[ITU-T.G.975]のFECコードと同様のRS(239,255,8)で、BERを1E-4から1E-12に改善します。

The FEC parity encapsulation is based on the framing of the Ethernet packet. The Ethernet packets are spaced by MAC rate adaptation, and the parity bytes are inserted after the packet in the provided space.

FECパリティカプセル化は、イーサネットパケットのフレーミングに基づいています。イーサネットパケットはMACレートアダプテーションによって間隔が空けられ、提供されたスペースでパケットの後にパリティバイトが挿入されます。

As the start and end of packet codewords also define the FEC boundaries, and they are outside the FEC protection, they are replaced by a series of symbols to reduce their vulnerability to errors.

パケットのコードワードの開始と終了もFEC境界を定義し、FEC保護の外側にあるため、エラーに対する脆弱性を減らすために一連のシンボルに置き換えられます。

The following diagram presents an FEC-protected frame:

次の図は、FECで保護されたフレームを示しています。

The FEC is added in a separate layer between the PCS and PMA layers of the [802.3].

FECは、[802.3]のPCS層とPMA層の間の別の層に追加されます。

The FEC layer introduces a fixed delay in receive path and transmit path.

2.3. Management Architecture
2.3. 管理アーキテクチャ

Each one of the EPON layers is accompanied by a management interface that is controlled through clause 30 of the [802.3ah]. As the [802.3ah] specification may be used for different applications, and some of the clauses may be used separately, the IEEE management clause allocates for each one of them a separate package. The MIB document follows this partition.

EPONレイヤーのそれぞれには、[802.3ah]の30節を通じて制御される管理インターフェイスが付属しています。 [802.3ah]仕様はさまざまなアプリケーションに使用でき、一部の条項は個別に使用できるため、IEEE管理条項はそれぞれに個別のパッケージを割り当てます。 MIBドキュメントはこのパーティションに従います。

The following diagram presents the relation of the MIB groups to the [802.3ah] layers:

次の図は、MIBグループと[802.3ah]レイヤーの関係を示しています。

The association is straightforward for the ONU interface. There is one logical and one physical interface, and a single copy exists for each layer that can be remotely queried by the OLT.

ONUインターフェースの場合、関連付けは簡単です。 1つの論理インターフェイスと1つの物理インターフェイスがあり、OLTによってリモートでクエリできる各レイヤーに1つのコピーが存在します。

At the OLT there is a single physical interface and N virtual interfaces for the virtual links of the ONUs (and another virtual interface for the broadcast virtual link). As can be seen from the layering diagram above, the MAC layer is virtually duplicated. Therefore, in this document it was selected that the management of a virtual interface is like a physical interface, an interface index is allocated for each one of the virtual links, and an additional interface index is allocated for the OLT.

OLTには、ONUの仮想リンク用の単一の物理インターフェースとN個の仮想インターフェース(およびブロードキャスト仮想リンク用の別の仮想インターフェース)があります。上記の階層図からわかるように、MAC層は事実上複製されています。したがって、このドキュメントでは、仮想インターフェイスの管理が物理インターフェイスのようなものであり、インターフェイスインデックスが各仮想リンクに割り当てられ、追加のインターフェイスインデックスがOLTに割り当てられることが選択されました。

To illustrate the interface modeling consider two devices; the first device has two physical interfaces, is typically located at a consumer's site, and is called an "ONU modem".

インターフェースモデリングを説明するために、2つのデバイスを考えます。最初のデバイスには2つの物理インターフェイスがあり、通常は消費者のサイトにあり、「ONUモデム」と呼ばれます。

An "ONU modem" is shown in the figure below:

「ONUモデム」を次の図に示します。

                            --------
             ONU interface | ONU   | 10 megabit interface
             --------------| modem |--------------------
                           ---------
        

This device would have 3 entries in the IF table, and one IF stack entry; for example:

このデバイスには、IFテーブルに3つのエントリと1つのIFスタックエントリがあります。例えば:

ifIndex=1 - interface for 10 megabit interface

ifIndex = 1-10メガビットインターフェイスのインターフェイス

ifIndex=2 - interface for the optical interface

ifIndex = 2-光インターフェースのインターフェース

ifIndex=200 - interface for the ONU interface

ifIndex = 200-ONUインターフェースのインターフェース

And then in the IF stack table:

そして、IFスタックテーブル:

ifStackHigherLayer=200, ifStackLowerLayer=2 - map between the physical and the ONU

ifStackHigherLayer = 200、ifStackLowerLayer = 2-物理とONUの間のマッピング

The second device has three physical interfaces, is typically located at the provider's site, and may be called a "headend".

2番目のデバイスには3つの物理インターフェイスがあり、通常はプロバイダーのサイトにあり、「ヘッドエンド」と呼ばれることがあります。

A "headend" is shown in the figure below:

「ヘッドエンド」を次の図に示します。

                               ---------
             1st OLT interface | Head  | gigE interface
             ------------------| end   |--------------------
                               |       |
             ------------------|       |
             2nd OLT interface |       |
                               ---------
        

This device would have 5 entries (when there are no attached ONUs) in the IF table, for example:

このデバイスのIFテーブルには、5つのエントリ(接続されたONUがない場合)があります。次に例を示します。

ifIndex=1 - interface for gigE interface

ifIndex = 1-gigEインターフェースのインターフェース

ifIndex=2 - interface for 1st optical interface

ifIndex = 2-最初の光インターフェースのインターフェース

ifIndex=3 - interface for 2nd optical interface

ifIndex = 3-2番目の光インターフェースのインターフェース

ifIndex=265535 - interface for the 1st OLT broadcast interface

ifIndex = 265535-1番目のOLTブロードキャストインターフェイスのインターフェイス

ifIndex=365535 - interface for the 2nd OLT broadcast interface

ifIndex = 365535-2番目のOLTブロードキャストインターフェースのインターフェース

And then in the IF stack table:

そして、IFスタックテーブル:

ifStackHigherLayer=265535, ifStackLowerLayer=2 - map between the 1st physical and its broadcast interface

ifStackHigherLayer = 265535、ifStackLowerLayer = 2-1番目の物理インターフェイスとそのブロードキャストインターフェイス間のマップ

ifStackHigherLayer=365535, ifStackLowerLayer=3 - map between the 2nd physical and its broadcast interface

ifStackHigherLayer = 365535、ifStackLowerLayer = 3-2番目の物理インターフェイスとそのブロードキャストインターフェイス間のマップ

If two ONUs connected to the first OLT interface, then for example, the following entries would be added to the IF table:

たとえば、2つのONUが最初のOLTインターフェイスに接続されている場合、次のエントリがIFテーブルに追加されます。

ifIndex=200001 - interface for the 1st ONU of 1st OLT

ifIndex = 200001-1番目のOLTの1番目のONUのインターフェース

ifIndex=200002 - interface for the 2nd ONU of 1st OLT

ifIndex = 200002-1番目のOLTの2番目のONUのインターフェース

And in the IF stack table:

そして、IFスタックテーブル:

ifStackHigherLayer=200001, ifStackLowerLayer=2 - map between the 1st physical and 1st ONU

ifStackHigherLayer = 200001、ifStackLowerLayer = 2-最初の物理と最初のONUの間のマッピング

ifStackHigherLayer=200002, ifStackLowerLayer=2 - map between the 1st physical and 2nd ONU

ifStackHigherLayer = 200002、ifStackLowerLayer = 2-最初の物理ONUと2番目のONUの間のマッピング

For each physical interface, there would be an entry (ifIndex) in the tables of the interface MIB module [RFC2863], MAU MIB module [RFC4836], and Etherlike MIB module [RFC3635]. Additionally, there would be entries (ifIndexes) for the virtual interfaces of the OLT interface. The justification for the additional allocation of indexes is that the virtual interfaces are quite well distinguished, as they connect different physical ONUs from the OLT side. For instance, there is a meaning for separate bad frames counter or bad octets counter for each virtual link, as the ONUs can be differently distanced. This is quite similar to a case of separate physical interfaces.

物理インターフェイスごとに、インターフェイスMIBモジュール[RFC2863]、MAU MIBモジュール[RFC4836]、およびEtherlike MIBモジュール[RFC3635]のテーブルにエントリ(ifIndex)があります。さらに、OLTインターフェイスの仮想インターフェイスのエントリ(ifIndexes)があります。インデックスの追加割り当ての正当性は、仮想インターフェースがOLT側から異なる物理ONUに接続するため、仮想インターフェースが非常によく区別されることです。たとえば、ONUの距離が異なる可能性があるため、仮想リンクごとに個別の不良フレームカウンターまたは不良オクテットカウンターの意味があります。これは、個別の物理インターフェイスの場合と非常に似ています。

The same partition concept exists for the MIB module of this document. Each row in the tables are indexed according to the ifIndex; specifically, there is a row for each virtual link. There are some control objects that are shared and are the same for the virtual interfaces (and they should have the same value for each ifIndex), but most of the objects have different values for N+1 logical interfaces at the OLT. This is done for each MIB group. It is a bit different from the [802.3ah] layering diagram, which presents the P2MP layer as a single layer, while duplicating the MAC and MAC client layers (please see the diagram above). However, from a management perspective, it is more convenient and neat to partition the management of the layers for the virtual links, as the atomic managed entity is the virtual link. It is also convenient to use the interface index of the virtual link for that purpose, as it is already used to index the rows of the virtual links at the Interface, MAU, and etherLike interfaces MIBs.

このドキュメントのMIBモジュールにも同じパーティションの概念が存在します。テーブルの各行には、ifIndexに従ってインデックスが付けられます。具体的には、仮想リンクごとに1つの行があります。共有され、仮想インターフェイスで同じであるいくつかのコントロールオブジェクトがあります(それらは各ifIndexで同じ値を持っている必要があります)、ほとんどのオブジェクトはOLTでN + 1論理インターフェイスの異なる値を持っています。これは、MIBグループごとに行われます。 [802.3ah]レイヤー図とは少し異なります。これは、P2MPレイヤーを1つのレイヤーとして提示し、MACレイヤーとMACクライアントレイヤーを複製しています(上の図を参照してください)。ただし、管理の観点からは、アトミック管理エンティティーが仮想リンクであるため、仮想リンクのレイヤーの管理を分割する方が便利で便利です。また、その目的で仮想リンクのインターフェースインデックスを使用すると便利です。これは、インターフェース、MAU、etherLikeインターフェースMIBで仮想リンクの行にインデックスを付けるためにすでに使用されているためです。

dot3ExtPkgOptIfTableは、EPON準拠インターフェイスの光インターフェイスの制御およびステータス表示に使用される、論理リンクごとのオブジェクトを定義します。

As described in the architecture section, each row in the tables is indexed according to the ifIndex; specifically, there is a row for each virtual link. There are a few control objects that are shared and have the same value for the virtual interfaces (and they should have the same value for each ifIndex), but most of the objects have different values for N+1 logical interfaces at the OLT. This is done for each MIB group. It is a bit different from the [802.3ah] layering diagram, which presents the P2MP layer as a single layer while duplicating the MAC and MAC client layers. However, from a management perspective, it is more convenient and neat to partition the management of the layers for the virtual links, as the atomic managed entity is the virtual link. It is also convenient to use the interface index of the virtual link for that purpose, as it is already used to index the rows of the virtual links at the Interface, MAU, and etherLike interfaces MIBs.

アーキテクチャのセクションで説明したように、テーブルの各行にはifIndexに従ってインデックスが付けられます。具体的には、仮想リンクごとに1つの行があります。共有され、仮想インターフェイスに同じ値を持ついくつかのコントロールオブジェクトがあります(各ifIndexに同じ値が必要です)が、ほとんどのオブジェクトはOLTのN + 1論理インターフェイスに異なる値を持っています。これは、MIBグループごとに行われます。これは、[802.3ah]レイヤー図とは少し異なります。この図は、P2MPレイヤーを1つのレイヤーとして提示し、MACおよびMACクライアントレイヤーを複製しています。ただし、管理の観点からすると、アトミック管理エンティティーは仮想リンクであるため、仮想リンクのレイヤーの管理を分割する方が便利で便利です。また、その目的で仮想リンクのインターフェースインデックスを使用すると便利です。これは、インターフェース、MAU、etherLikeインターフェースMIBで仮想リンクの行にインデックスを付けるためにすでに使用されているためです。

For example, provided below are the values of the MPCP control table of an OLT with 3 registered ONUs:

4. Relation to Other MIB Modules
4. 他のMIBモジュールとの関係
4.1. Relation to the Interfaces MIB and Ethernet-like Interfaces MIB
4.1. インターフェースMIBおよびイーサネットのようなインターフェースMIBとの関係

EPON interface is a kind of Ether-like interface. This MIB module extends the objects of the Interface MIB and the Ether-like Interfaces MIB for an EPON type interface.

EPONインターフェイスは、一種のEther-likeインターフェイスです。このMIBモジュールは、EPONタイプのインターフェイスのインターフェイスMIBおよびEther-likeインターフェイスMIBのオブジェクトを拡張します。

Implementing this module therefore MUST require implementation of the Interfaces MIB module [RFC2863] and the Ethernet-like Interfaces MIB module [RFC3635].

したがって、このモジュールを実装するには、インターフェースMIBモジュール[RFC2863]およびイーサネットのようなインターフェースMIBモジュール[RFC3635]の実装が必要です。

Thus, each managed EPON interface would have a corresponding entry in the mandatory tables of the Ether-like MIB module found in [RFC3635], and likewise in the tables of the Interface MIB module found in [RFC2863]. Also each managed virtual EPON interface would have a corresponding entry in the mandatory tables of the Ether-like MIB module found in [RFC3635], and likewise in the tables of the Interface MIB module found in [RFC2863] with a dedicated ifIndex for this interface.

したがって、各管理対象EPONインターフェイスは、[RFC3635]にあるEther-like MIBモジュールの必須テーブルに、[RFC2863]にあるインターフェイスMIBモジュールのテーブルにも同様に対応するエントリがあります。また、各管理対象仮想EPONインターフェイスは、[RFC3635]にあるEther-like MIBモジュールの必須テーブルに対応するエントリを持ちます。同様に、[RFC2863]にあるインターフェイスMIBモジュールのテーブルにも、このインターフェイス専用のifIndexがあります。 。

In this document, there is no replication of the objects from these MIBs. Therefore, for instance, the document is defining dot3MpcpRemoteMACAddress only while assuming that the local MAC address object is already defined in [RFC3635].

このドキュメントでは、これらのMIBからのオブジェクトの複製はありません。したがって、たとえば、ドキュメントはdot3MpcpRemoteMACAddressのみを定義していますが、ローカルMACアドレスオブジェクトはすでに[RFC3635]で定義されていると想定しています。

The interface MIB module [RFC2863] defines the interface index (ifIndex). Interface Index, as specified in [RFC2863], is used in this MIB Module as an index to the EPON MIB tables. The ifIndex is used to denote the physical interface and the virtual link interfaces at the OLT. The OLT interface and the virtual link interfaces are stacked using the ifStack table defined in [RFC2863], and the ifInvStack defined in [RFC2864]. The OLT interface is the lower layer of all other interfaces associated with the virtual links.

インターフェースMIBモジュール[RFC2863]は、インターフェースインデックス(ifIndex)を定義します。 [RFC2863]で指定されているインターフェイスインデックスは、このMIBモジュールでEPON MIBテーブルへのインデックスとして使用されます。 ifIndexは、OLTの物理インターフェースと仮想リンクインターフェースを示すために使用されます。 OLTインターフェースと仮想リンクインターフェースは、[RFC2863]で定義されているifStackテーブルと、[RFC2864]で定義されているifInvStackを使用してスタックされます。 OLTインターフェイスは、仮想リンクに関連付けられている他のすべてのインターフェイスの下位層です。

This document defines the specific EPON objects of an ONU interface and an OLT interface. Information in the tables is per LLID. The rows in the EPON MIB tables referring to the LLIDs are denoted with the corresponding ifIndexes of the virtual link interfaces.

このドキュメントでは、ONUインターフェイスとOLTインターフェイスの特定のEPONオブジェクトを定義します。表の情報はLLIDごとです。 LLIDを参照するEPON MIBテーブルの行は、仮想リンクインターフェイスの対応するifIndexで示されます。

Please note that each virtual interface does not have a different physical MAC address at the OLT, as the physical interface is the same. It is specified in the [802.3ah], Section 64.1.2. The corresponding object of the Ether-like interface MIB is duplicated for all the virtual interfaces.

物理インターフェイスは同じであるため、各仮想インターフェイスはOLTで異なる物理MACアドレスを持たないことに注意してください。 [802.3ah]、セクション64.1.2で指定されています。 Ether-likeインターフェースMIBの対応するオブジェクトは、すべての仮想インターフェースに複製されます。

For example, the values of the Interface MIB objects are presented in the following tables, for an OLT with 3 registered ONUs: The table below presents the objects of the Interface MIB of an ONU in working mode.

たとえば、3つの登録されたONUを持つOLTについて、インターフェースMIBオブジェクトの値を次の表に示します。以下の表は、作業モードのONUのインターフェースMIBのオブジェクトを示しています。

The creation of a row for a virtual link is done when the virtual link is established (ONU registers), and deletion is done when the virtual link is deleted (ONU deregisters).

仮想リンクの行の作成は、仮想リンクが確立される(ONUレジスター)ときに行われ、削除は、仮想リンクが削除される(ONUが登録解除される)ときに行われます。

The EPON MIB module also extends the Interface MIB module with a set of counters, which are specific for the EPON interface. The EPON MIB module implements the same handling of the counters when the operation of the interface starts or stops. The interface MIB document describes the possible behavior of counters when an interface is re-initialized using the ifCounterDiscontinuityTime indicator, indicating the discontinuity of the counters. Please see [RFC2863], Section 3.1.5, page 11 for more information. The counters of the EPON MIB should be handled in a similar manner.

EPON MIBモジュールは、EPONインターフェースに固有の一連のカウンターでインターフェースMIBモジュールも拡張します。 EPON MIBモジュールは、インターフェイスの動作が開始または停止したときに、カウンターの同じ処理を実装します。インターフェイスMIBドキュメントには、インターフェイスがifCounterDiscontinuityTimeインジケータを使用して再初期化されたときのカウンタの可能な動作が記述されており、カウンタの不連続性を示しています。詳細については、[RFC2863]、セクション3.1.5、11ページを参照してください。 EPON MIBのカウンタは、同様の方法で処理する必要があります。

4.2. Relation to the IEEE 802.3 MAU MIBs
4.2. IEEE 802.3 MAU MIBとの関係

The MAU types of the EPON Interface are defined in the amended MAU MIB document. This document assumes the implementation of the MAU MIB for this purpose and does not repeat the EPON MAU types. Therefore, implementing this module MUST require implementation of the MAU-MIB module [RFC4836].

EPONインターフェイスのMAUタイプは、修正されたMAU MIBドキュメントで定義されています。このドキュメントは、この目的のためにMAU MIBの実装を想定しており、EPON MAUタイプを繰り返さない。したがって、このモジュールを実装するには、MAU-MIBモジュール[RFC4836]の実装が必要です。

The handling of the ifMAU tables for the EPON case is similar to the handling described in the former section for the Interface and Ether-like interface MIBs. A single row exists for the ONU in the ifMauTable. A row for each virtual link (N+1 rows) exists at the OLT, with a separate value of ifMauIfIndex for each virtual link.

EPONケースのifMAUテーブルの処理は、前のセクションで説明したインターフェイスおよびEther-likeインターフェイスMIBの処理と同様です。 ifMauTableのONUに単一行が存在します。各仮想リンクの行(N + 1行)がOLTに存在し、仮想リンクごとにifMauIfIndexの個別の値があります。

As specified above, the rows for the ONU interface, the OLT interface, and the OLT broadcast interface are created in initialization.

上記のように、ONUインターフェース、OLTインターフェース、およびOLTブロードキャストインターフェースの行は、初期化時に作成されます。

The creation of a row for a virtual link is done when the virtual link is established (ONU registers), and deletion is done when the virtual link is deleted (ONU deregisters).

仮想リンクの行の作成は、仮想リンクが確立される(ONUレジスター)ときに行われ、削除は、仮想リンクが削除される(ONUが登録解除される)ときに行われます。

4.3. Relation to the EFM OAM MIB
4.3. EFM OAM MIBとの関係

The EPON interfaces are aimed to the optical access networks and most probably will be accompanied with the implementation of the OAM section of the [802.3ah]. Therefore, the EFM OAM MIB module [RFC4878] MAY be implemented when this MIB module is implemented defining managed objects for the OAM layer that are complementary to the EFM EPON MIB module. As the OAM is defined for a point-to-point link it is implemented in this case using the virtual links that are defined for the P2MP network, so that an instance is held for each Logical Link Identifier (LLID) of the EPON. The corresponding ifIndex of the virtual link is used as the ifIndex of the tables of the OAM MIB module for this purpose.

EPONインターフェイスは光アクセスネットワークを目的としており、おそらく[802.3ah]のOAMセクションの実装が伴うでしょう。したがって、EFM OAM MIBモジュール[RFC4878]は、このMIBモジュールが、EFM EPON MIBモジュールを補完するOAMレイヤーの管理対象オブジェクトを定義して実装されるときに実装される場合があります。 OAMはポイントツーポイントリンクに対して定義されているため、この場合、P2MPネットワークに対して定義されている仮想リンクを使用して実装されているため、EPONの各論理リンク識別子(LLID)に対してインスタンスが保持されます。仮想リンクの対応するifIndexは、この目的でOAM MIBモジュールのテーブルのifIndexとして使用されます。

4.4. Relation to the Bridge MIB
4.4. ブリッジMIBとの関係

It is very probable that an EPON OLT will implement a bridging functionality above the EPON interface layer, bridging between the EPON users and the network. Bridge functionality is specified at [802.1d]. In this scenario, the virtual ports of the EPON are corresponding to the virtual bridge ports. There is a direct mapping between the bridge ports and the LLIDs, which are virtual EPON channels.

EPON OLTがEPONインターフェース層の上にブリッジ機能を実装し、EPONユーザーとネットワークの間をブリッジする可能性は非常に高いです。ブリッジ機能は[802.1d]で指定されています。このシナリオでは、EPONの仮想ポートは仮想ブリッジポートに対応しています。ブリッジポートと仮想EPONチャネルであるLLIDの間には直接マッピングがあります。

Therefore, the bridge MIB modules ([RFC4188] and [RFC1525]) MAY be implemented when the EFM EPON MIB module is implemented for an EPON OLT, defining managed objects for the bridge layer.

したがって、ブリッジMIBモジュール([RFC4188]と[RFC1525])は、EPON ELT MIBモジュールがEPON OLTに実装され、ブリッジ層の管理対象オブジェクトを定義するときに実装される場合があります。

The values of dot1dBasePortIfIndex would correspond to the ifIndex of the virtual port (1 for LLID1, 2 for LLID2, etc.).

dot1dBasePortIfIndexの値は、仮想ポートのifIndexに対応します(LLID1の場合は1、LLID2の場合は2など)。

The broadcast virtual EPON interface of the OLT has no direct mapping to a virtual bridge port as it is not port specific but used for broadcast traffic.

OLTのブロードキャスト仮想EPONインターフェイスは、ポート固有ではないがブロードキャストトラフィックに使用されるため、仮想ブリッジポートへの直接マッピングはありません。

5. Mapping of IEEE 802.3ah Managed Objects

             number of virtual links to 32768.  Typically the number
             of expected virtual links in a PON is like the number of
             ONUs, which is 32-64, plus an additional entry for

           "An object defining the FEC mode of operation of the
            interface, and indicating its state.  The modes defined in
            this object are extensions to the FEC modes defined in
            the dot3EponFecMode object.
            When noFECEnabled(1), the interface does not enable FEC
            mode.
            When fecTxEnabled(2), the interface enables the FEC
            transmit mode.
            When fecRxEnabled(3), the interface enables the FEC
            receive mode.
            When fecTxRxEnabled(4), the interface enables the FEC
            transmit and receive mode.
            This object is applicable for an OLT and an ONU.  At the
            OLT, it has a distinct value for each virtual interface.
            The FEC counters are referring to the receive path.  The
            FEC counters will stop when the FEC receive mode of the
            interface is disabled, as defined by fecRxEnabled(3)
            and fecTxRxEnabled(4) values.
            The counters:
             dot3EponFecPCSCodingViolation - not affected by FEC
             mode.
             dot3EponFecCorrectedBlocks - stops counting when
             Rx_FEC is not enabled (noFecEnabled(1) and
             fecTxEnabled(2)).
             dot3EponFecUncorrectableBlocks - stops counting when
             Rx_FEC is not enabled (noFecEnabled(1) and
             fecTxEnabled(2)).
             dot3EponFecBufferHeadCodingViolation - stops counting
             when Rx_FEC is not enabled (noFecEnabled(1) and
             fecTxEnabled(2)).
            The objects:
             dot3EponFecAbility - indicates the FEC ability and is
             not affected by the FEC mode.
             dot3EponFecMode - indicates the FEC mode for combined RX
             and TX.

      DESCRIPTION
              "A table of the extended package objects for queue
               management.  The [802.3ah] MPCP defines a report message
               of the occupancy of the transmit queues for the feedback
               BW request from the ONUs.  These queues serve the uplink
               transmission of the ONU and data is gathered there until
               the ONU is granted for transmission.
               The management table of the queues is added here mainly
               to control the reporting and to gather some statistics
               of their operation.  This table is not duplicating
               existing management objects of bridging queues,
               specified in [802.1d], since the existence of a
               dedicated transmit queuing mechanism is implied in the
               [802.3ah], and the ONU may be a device that is not a
               bridge with embedded bridging queues.
               The format of the REPORT message, as specified
               in [802.3], is presented below:

               The 'Queue report' field reports the occupancy of each
               uplink transmission queue.
               The number of queue sets defines the number of the
               reported sets, as would be explained in the description
               of the dot3ExtPkgQueueSetsTable table.  For each set the
               report bitmap defines which queue is present in the
               report, meaning that although the MPCP REPORT message
               can report up to 8 queues in a REPORT message, the
               actual number is flexible.  The Queue table has a
               variable size that is limited by the
               dot3ExtPkgObjectReportMaximumNumQueues object, as an
               ONU can have fewer queues to report.
               The entries in the table are control and status
               indication objects for managing the queues of an EPON
               interface that are gathered in an extended package as
               an addition to the objects that are based on the
               [802.3ah] attributes.
               Each object has a row for every virtual link and for
               every queue in the report.
               The LLID field, as defined in the [802.3ah], is a 2-byte
               register (15-bit field and a broadcast bit) limiting the
               number of virtual links to 32768.  Typically the number
               of expected virtual links in a PON is like the number of
               ONUs, which is 32-64, plus an additional entry for
               broadcast LLID (with a value of 0xffff).
               The number of queues is between 0 and 7 and limited by
               dot3ExtPkgObjectReportMaximumNumQueues."

dot3ExtPkgQueueSetsTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot3ExtPkgQueueSetsEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A table of Extended package objects used for the management of the queue_sets. Entries are control and status indication objects of an EPON interface, which are gathered in an extended package as an addition to the objects based on the [802.3ah] attributes. The objects in this table are specific for the queue_sets, which are reported in the MPCP REPORT message as defined in [802.3ah], clause 64. The [802.3ah] MPCP defines a report message of the occupancy of the transmit queues for the feedback BW request from the ONUs. These queues serve the uplink transmission of the ONU and data is gathered there until the ONU is granted for transmission.

dot3ExtPkgQueueSetsTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot3ExtPkgQueueSetsEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "A table of the extended package objects used for the management of the queue_sets。 [802.3ah]属性に基づくオブジェクトへの追加としてのパッケージ。このテーブルのオブジェクトは、[802.3ah]の64節で定義されているようにMPCP REPORTメッセージで報告されるqueue_setsに固有です。[802.3ah ] MPCPは、ONUからのフィードバックBW要求に対する送信キューの占有率のレポートメッセージを定義します。これらのキューは、ONUのアップリンク送信を処理し、ONUの送信が許可されるまでデータがそこで収集されます。

               The management table of the queues_sets is added here
               mainly to control the reporting and to gather some
               statistics of their operation.  This table is not
               duplicating existing management objects of bridging
               queues, specified in [802.1d], since the existence of a
               dedicated transmit queuing mechanism is implied in the
               [802.3ah], and the ONU may be a device that is not a
               bridge with embedded bridging queues.
               The format of the REPORT message, as specified
               in [802.3], is presented below:

               As can be seen from the message format, the ONU
               interface reports of the status of up to 8 queues
               and it can report in a single MPCP REPORT message
               of a few sets of queues.
               The number of queue_sets defines the number of the
               reported sets, and it can reach a value of up to 8.
               It means that an ONU can hold a variable number of
               sets between 0 and 7.
               The dot3ExtPkgQueueSetsTable table has a variable
               queue_set size that is limited by the
               dot3ExtPkgObjectReportMaximumNumThreshold object as an
               ONU can have fewer queue_sets to report.
               The 'Queue report' field reports the occupancy of each
               uplink transmission queue.  The queue_sets can be used to
               report the occupancy of the queues in a few levels as to
               allow granting, in an accurate manner, of only part of
               the data available in the queues.  A Threshold is
               defined for each queue_set to define the level of the
               queue that is counted for the report of the occupancy.
               The threshold is reflected in the queue_set table by the
               dot3ExtPkgObjectReportThreshold object.
               For each queue set, the report bitmap defines which
               queues are present in the report, meaning that
               although the MPCP REPORT message can report of up to 8
               queues in a REPORT message, the actual number is
               flexible.
               The dot3ExtPkgQueueSetsTable table has a variable queue
               size that is limited by the
               dot3ExtPkgObjectReportMaximumNumQueues object as an ONU
               can have fewer queues to report.
               Each object has a row for every virtual link, for each
               queue in the report and for each queue_set in the queue.
               The LLID field, as defined in the [802.3ah], is a 2-byte
               register (15-bit field and a broadcast bit) limiting the
               number of virtual links to 32768.  Typically the number
               of expected virtual links in a PON is like the number of
               ONUs, which is 32-64, plus an additional entry for
               broadcast LLID (with a value of 0xffff).
               The number of queues is between 0 and 7 and limited by
               dot3ExtPkgObjectReportMaximumNumQueues.
               The number of queues_sets is between 0 and 7 and limited
               by dot3ExtPkgObjectReportMaximumNumThreshold."

Changing dot3ExtPkgOptIfTransmitEnable state can lead to a halt in the optical transmission of the respective interface, leading to an interruption of service for the users connected to the respective EPON interface.

dot3ExtPkgOptIfTransmitEnable状態を変更すると、それぞれのインターフェイスの光伝送が停止し、それぞれのEPONインターフェイスに接続しているユーザーのサービスが中断する可能性があります。

The user of this MIB module must therefore be aware that support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations.

したがって、このMIBモジュールのユーザーは、適切な保護のない非セキュア環境でのSET操作のサポートがネットワーク操作に悪影響を及ぼす可能性があることに注意する必要があります。

The readable objects in this MIB module (i.e., those with MAX-ACCESS other than not-accessible) may be considered sensitive in some environments since, collectively, they provide information about the performance of network interfaces and can reveal some aspects of their configuration. In such environments it is important to control even GET and NOTIFY access to these objects and possibly even to encrypt their values when sending them over the network via SNMP.

このMIBモジュール内の読み取り可能なオブジェクト(つまり、アクセス不可以外のMAX-ACCESSを持つオブジェクト)は、それらが集合的にネットワークインターフェイスのパフォーマンスに関する情報を提供し、構成のいくつかの側面を明らかにできるため、一部の環境では機密と見なされる場合があります。このような環境では、これらのオブジェクトへのGETおよびNOTIFYアクセスを制御し、SNMP経由でネットワーク経由で送信するときに値を暗号化することも重要です。

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より前のSNMPバージョンには、十分なセキュリティが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)セキュリティで保護されている場合でも、セキュリティで保護されたネットワーク上の誰にアクセスを許可するか、このオブジェクトのGET / SET(読み取り/変更/作成/削除)を許可するかは制御できません。 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).

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).

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バージョンの配備は推奨されません。代わりに、SNMPv3を展開して暗号化セキュリティを有効にすることをお勧めします。次に、このMIBモジュールのインスタンスにアクセスを許可するSNMPエンティティが、実際にGETまたはSET(変更)に対する正当な権限を持つプリンシパル(ユーザー)にのみオブジェクトへのアクセスを許可するように適切に構成されていることを確認するのは、顧客/オペレーターの責任です。 / create / delete)それら。
