This document defines a Management Information Base (MIB) module for use with network management protocols in the Internet community. IP Traffic Flow Security (IP-TFS) extensions, as defined in [RFC9347], are enhancements to an IPsec tunnel Security Association (SA) to provide improved traffic confidentiality.
このドキュメントでは、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管理情報ベース（MIB）モジュールを定義しています。[RFC9347]で定義されているIPトラフィックフローセキュリティ（IP-TFS）拡張機能は、IPSECトンネルセキュリティ協会（SA）の強化であり、トラフィックの機密性を改善します。
The objects defined here are the same as [RFC9348], with the exception that only operational or state data is supported. By making operational data accessible via SNMP, existing network management systems can monitor IP-TFS. This data is listed in the MIB tree in Section 4.1. This module uses the YANG data model as a reference point for managed objects. Note that an IETF MIB model for IPsec was never standardized; however, the structures here could be adapted to existing proprietary MIB implementations where SNMP is used to manage networks.
ここで定義されているオブジェクトは[RFC9348]と同じですが、運用または状態のデータのみがサポートされていることを除いて。SNMPを介して運用データをアクセスできるようにすることにより、既存のネットワーク管理システムはIP-TFを監視できます。このデータは、セクション4.1のMIBツリーにリストされています。このモジュールは、管理されたオブジェクトの基準点としてYangデータモデルを使用します。IPSECのIETF MIBモデルは標準化されなかったことに注意してください。ただし、ここの構造は、SNMPがネットワークを管理するために使用される既存の独自のMIB実装に適合させることができます。
For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to Section 7 of [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、[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, [RFC2578], STD 58, [RFC2579] and STD 58, [RFC2580].
管理されたオブジェクトは、管理情報ベースまたはMIBと呼ばれる仮想情報ストアからアクセスされます。MIBオブジェクトは通常、単純なネットワーク管理プロトコル（SNMP）からアクセスされます。MIB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、STD 58、[RFC2578]、STD 58、[RFC2579]およびSTD 58、[RFC2580]に記載されているSMIV2に準拠したMIBモジュールを指定します。
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 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
この文書のキーワード "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", および "OPTIONAL" はBCP 14 [RFC2119] [RFC8174]で説明されているように、すべて大文字の場合にのみ解釈されます。
This document defines the MIB for access to operational parameters of IP Traffic Flow Security (IP-TFS). IP-TFS, defined in [RFC9347], configures a Security Association for tunnel mode IPsec with characteristics that improve traffic confidentiality and reduce bandwidth efficiency loss.
このドキュメントでは、IPトラフィックフローセキュリティ（IP-TFS）の運用パラメーターへのアクセスのためのMIBを定義しています。[RFC9347]で定義されているIP-TFSは、トラフィックの機密性を改善し、帯域幅の効率の損失を減らす特性を備えたトンネルモードIPSECのセキュリティ協会を構成します。
This document is based on the concepts and management model defined in [RFC9348]. This document assumes familiarity with the IPsec concepts described in [RFC4301], IP-TFS as described in [RFC9347], and the IP-TFS management model described in [RFC9348].
このドキュメントは、[RFC9348]で定義されている概念と管理モデルに基づいています。このドキュメントは、[RFC4301]、[RFC9347]で説明されているIP-TFS、および[RFC9348]で説明されているIP-TFS管理モデルに記載されているIPSECの概念に精通しています。
This document specifies an extensible operational model for IP-TFS. It reuses the management model defined in [RFC9348]. It allows SNMP systems to read operational objects (which include configured objects) from IP-TFS.
このドキュメントは、IP-TFSの拡張可能な運用モデルを指定します。[RFC9348]で定義されている管理モデルを再利用します。SNMPシステムは、IP-TFSから動作オブジェクト（構成されたオブジェクトを含む）を読み取ることができます。

DESCRIPTION
"When set to true, the default, this enables the
congestion control on-the-wire exchange of data that is
required by congestion control algorithms, as defined by
RFC 5348. When set to false, IP-TFS sends fixed-sized
packets over an IP-TFS tunnel at a constant rate."

DESCRIPTION
"Packet size is either auto-discovered or manually
configured. If usePathMtuDiscovery is true, the system
utilizes path-mtu to determine the maximum IP-TFS packet
size. If the packet size is explicitly configured,
then it will only be adjusted downward if use-path-mtu
is set."

l2FixedRate OBJECT-TYPE
SYNTAX CounterBasedGauge64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The IP-TFS bit rate may be specified as a layer 2 wire
rate. On transmission, the target bandwidth/bit rate in
bits per second (bps) for the IP-TFS tunnel. This rate is
the nominal timing for the fixed-size packet. If
congestion control is enabled, the rate may be adjusted
down."

DESCRIPTION
"The IP-TFS bit rate may be specified as a layer 3 packet
rate. On transmission, the target bandwidth/bit rate in
bps for the IP-TFS tunnel. This rate is the nominal timing
for the fixed-size packet. If congestion control is
enabled, the rate may be adjusted down."
::= { iptfsConfigTableEntry 6 }
dontFragment OBJECT-TYPE
SYNTAX TruthValue
MAX-ACCESS read-only

DESCRIPTION
"On transmission, disable packet fragmentation across
consecutive IP-TFS tunnel packets; inner packets larger
than what can be transmitted in outer packets will be
dropped."
::= { iptfsConfigTableEntry 7 }
maxAggregationTime OBJECT-TYPE
SYNTAX NanoSeconds
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"On transmission, the maximum aggregation time is the
maximum length of time a received inner packet can be
held prior to transmission in the IP-TFS tunnel. Inner
packets that would be held longer than this time, based
on the current tunnel configuration, will be dropped
rather than be queued for transmission."
::= { iptfsConfigTableEntry 8 }
windowSize OBJECT-TYPE
SYNTAX UnsignedShort
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"On reception, the maximum number of out-of-order
packets that will be reordered by an IP-TFS receiver
while performing the reordering operation. The value 0
disables any reordering."
::= { iptfsConfigTableEntry 9 }
sendImmediately OBJECT-TYPE
SYNTAX TruthValue
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"On reception, send inner packets as soon as possible; do
not wait for lost or misordered outer packets.
Selecting this option reduces the inner (user) packet
delay but can amplify out-of-order delivery of the inner
packet stream in the presence of packet aggregation and
any reordering."
::= { iptfsConfigTableEntry 10 }
lostPacketTimerInterval OBJECT-TYPE
SYNTAX NanoSeconds
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"On reception, this interval defines the length of time
an IP-TFS receiver will wait for a missing packet before
considering it lost. If not using send-immediately,
then each lost packet will delay inner (user) packets
until this timer expires. Setting this value too low can
impact reordering and reassembly."

Table 1
The MIB specified in this document can read the operational behavior of IP Traffic Flow Security. For the implications regarding write configuration, consult [RFC9347], which defines the functionality.
このドキュメントで指定されたMIBは、IPトラフィックフローセキュリティの運用動作を読み取ることができます。書き込み構成に関する意味については、機能を定義する[RFC9347]を参照してください。
There are no management objects defined in this MIB module that have a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET operations.
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持つ管理オブジェクトはありません。したがって、このMIBモジュールが正しく実装されている場合、侵入者が直接SNMPセット操作を介してこのMIBモジュールの管理オブジェクトを変更または作成できるリスクはありません。
Some of the objects in this MIB module may be considered sensitive or vulnerable in some network environments. This includes INDEX objects with a MAX-ACCESS of not-accessible, and any indices from other modules exposed via AUGMENTS. 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:
このMIBモジュールの一部のオブジェクトは、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。これには、アクセス不可能な最大アクセスを備えたインデックスオブジェクト、および増加を介して公開された他のモジュールからのインデックスが含まれます。したがって、これらのオブジェクトへのアクセスを取得および/または通知することさえ制御し、SNMPを介してネットワーク上に送信するときにこれらのオブジェクトの値を暗号化することも重要です。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。
* iptfsInnerStatsTable and iptfsOuterStatsTable: Access to IP inner and outer Traffic Flow Security statistics can provide information that IP Traffic Flow Security obscures, such as the true activity of the flows using IP Traffic Flow Security.
* IPTFSINNERSTATSTABLEおよびIPTFSOUTERSTATSTABLE：IP内および外部トラフィックフローセキュリティ統計へのアクセスは、IPトラフィックフローセキュリティを使用したフローの真のアクティビティなど、IPトラフィックフローセキュリティが不明瞭になる情報を提供できます。
SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPsec), there is no control as to who on the secure network is allowed to access and GET (read) 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、セキュアネットワーク上の誰がこのMIBモジュールのオブジェクトにアクセスして取得（読み取る）を許可するかについての制御はありません。
Implementations SHOULD provide the security features described by the SNMPv3 framework (see [RFC3410]), and implementations claiming compliance to the SNMPv3 standard MUST include full support for authentication and privacy via the User-based Security Model (USM) [RFC3414] with the AES cipher algorithm [RFC3826]. Implementations MAY also provide support for the Transport Security Model (TSM) [RFC5591] in combination with a secure transport such as SSH [RFC5592] or TLS/DTLS [RFC6353].
実装は、SNMPV3フレームワーク（[RFC3410]を参照）で説明されているセキュリティ機能を提供する必要があり、SNMPV3標準のコンプライアンスを主張する実装には、AESとのユーザーベースのセキュリティモデル（USM）[RFC3414]を介した認証とプライバシーの完全なサポートを含める必要があります。暗号アルゴリズム[RFC3826]。実装は、SSH [RFC5592]やTLS/DTLS [RFC6353]などの安全な輸送と組み合わせて、輸送セキュリティモデル（TSM）[RFC5591]のサポートを提供する場合があります。
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。
