1. Introduction

 This memo defines a portion of the Management Information Base (MIB)
 module for use with network management protocols in the Internet
 community.  In particular, it describes managed objects used for
 managing PTP devices including ordinary clocks, transparent clocks,
 and boundary clocks.
 This MIB module is restricted to reading standard PTP data elements,
 as described in [IEEE-1588-2008].  This enables it to monitor the
 operation of PTP clocks within the network.  It is envisioned that
 this MIB module will complement other managed objects to be defined
 that will provide more detailed information on the performance of PTP
 clocks supporting the Telecom Profile defined in [G.8265.1] and any
 future profiles that may be defined.  Those objects are considered
 out of scope for the current document.
 Similarly, this MIB module is read-only and not intended to provide
 the ability to configure PTP clocks.  Since PTP clocks are often
 embedded in other network elements such as routers, switches, and
 gateways, this ability is generally provided via the configuration
 interface for the network element.
 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.

1.1. Relationship to Other Profiles and MIBs

 This MIB module is intended to be used with the default PTP profile
 described in [IEEE-1588-2008] when running over the IP network layer.
 As stated above, it is envisioned that this MIB module will
 complement other managed objects to be defined to monitor and measure
 the performance of PTP clocks supporting specific PTP profiles, e.g.,
 the Telecom Profile defined in [G.8265.1].
 Some other PTP profiles have their own MIB modules defined as part of
 the profile, and this MIB module is not intended to replace those MIB
 modules.

2. The Internet-Standard Management Framework

 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].

3. Overview

 The objects defined in this MIB module are to be used when describing
 the Precision Time Protocol (PTP), as defined in [IEEE-1588-2008].
 Section 6 of [IEEE-1588-2008] provides an overview of synchronization
 networks using PTP.
 Terms used in this document have meanings as defined in Section 3.1
 of [IEEE-1588-2008].

      authors of the code.  All rights reserved.
      Redistribution and use in source and binary forms, with or

      forth in Section 4.c of the IETF Trust's Legal Provisions
      Relating to IETF Documents
      (http://trustee.ietf.org/license-info).
      Overview of PTP version 2 (IEEE Std. 1588-2008)
      [IEEE-1588-2008] defines a protocol enabling precise
      synchronization of clocks in measurement and control systems
      implemented with packet-based networks, the Precision Time
      Protocol version 2 (PTPv2).  This MIB module does not address
      PTPv1, the earlier version defined in IEEE Std. 1588-2002.
      The protocol is applicable to network elements communicating
      using IP.  The protocol enables heterogeneous systems that
      include clocks of various inherent precision, resolution, and
      stability to synchronize to a grandmaster clock.
      The protocol supports system-wide synchronization accuracy in
      the sub-microsecond range with minimal network and local clock
      computing resources.  [IEEE-1588-2008] uses UDP/IP or
      Ethernet and can be adapted to other mappings.  It includes
      formal mechanisms for message extensions, higher sampling rates,
      correction for asymmetry, a clock type to reduce error
      accumulation in large topologies, and specifications on how to
      incorporate the resulting additional data into the
      synchronization protocol.  [IEEE-1588-2008] also defines
      conformance and management capability.
      MIB description
      This MIB module supports the Precision Time Protocol version 2
      (PTPv2, hereafter designated as PTP) features of network element
      system devices, when using the default PTP profile described in
      [IEEE-1588-2008] when running over the IP network layer.
      It is envisioned that this MIB module will complement other
      managed objects to be defined to monitor and measure the
      performance of the PTP devices and telecom clocks supporting
      specific PTP profiles.

Shankarkumar, et al. Standards Track [Page 6] RFC 8173 PTPv2 MIB June 2017

      Some other PTP profiles have their own MIB modules defined as
      part of the profile, and this MIB module is not intended to
      replace those MIB modules.
      Technical terms used in this module are defined in
      [IEEE-1588-2008].
      The MIB module refers to sections of [IEEE-1588-2008].

5. Security Considerations

 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.
 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:
    ptpDomainClockPortsTotal, ptpbaseSystemDomainTotals, and
    ptpbaseSystemProfile expose general information about the clock
    system.
    ptpbaseClockRunningState, ptpbaseClockRunningPacketsSent, and
    ptpbaseClockRunningPacketsReceived expose a clock's current
    running status.
    ptpbaseClockCurrentDSStepsRemoved,
    ptpbaseClockCurrentDSOffsetFromMaster, and
    ptpbaseClockCurrentDSMeanPathDelay expose the values of a clock's
    current dataset (currentDS).
    ptpbaseClockParentDSParentPortIdentity,
    ptpbaseClockParentDSParentStats, ptpbaseClockParentDSOffset,
    ptpbaseClockParentDSClockPhChRate,
    ptpbaseClockParentDSGMClockIdentity,
    ptpbaseClockParentDSGMClockPriority1,
    ptpbaseClockParentDSGMClockPriority2,
    ptpbaseClockParentDSGMClockQualityClass,
    ptpbaseClockParentDSGMClockQualityAccuracy, and
    ptpbaseClockParentDSGMClockQualityOffset expose the values of a
    clock's parent dataset (parentDS).
    ptpbaseClockDefaultDSTwoStepFlag,
    ptpbaseClockDefaultDSClockIdentity,
    ptpbaseClockDefaultDSPriority1, ptpbaseClockDefaultDSPriority2,
    ptpbaseClockDefaultDSSlaveOnly, ptpbaseClockDefaultDSQualityClass,
    ptpbaseClockDefaultDSQualityAccuracy, and
    ptpbaseClockDefaultDSQualityOffset expose the values of a clock's
    default dataset (defaultDS).

    ptpbaseClockTimePropertiesDSCurrentUTCOffsetValid,
    ptpbaseClockTimePropertiesDSCurrentUTCOffset,
    ptpbaseClockTimePropertiesDSLeap59,
    ptpbaseClockTimePropertiesDSLeap61,
    ptpbaseClockTimePropertiesDSTimeTraceable,
    ptpbaseClockTimePropertiesDSFreqTraceable,
    ptpbaseClockTimePropertiesDSPTPTimescale, and
    ptpbaseClockTimePropertiesDSSource expose the values of a clock's
    time properties dataset (timePropertiesDS).
    ptpbaseClockTransDefaultDSClockIdentity,
    ptpbaseClockTransDefaultDSNumOfPorts,
    ptpbaseClockTransDefaultDSDelay, and
    ptpbaseClockTransDefaultDSPrimaryDomain expose the values of a
    transparent clock's default dataset (transparentClockDefaultDS).
    ptpbaseClockPortName, ptpbaseClockPortRole,
    ptpbaseClockPortSyncTwoStep,
    ptpbaseClockPortCurrentPeerAddressType,
    ptpbaseClockPortCurrentPeerAddress, and
    ptpbaseClockPortNumOfAssociatedPorts expose general information
    about a clock port.
    ptpbaseClockPortRunningName, ptpbaseClockPortRunningState,
    ptpbaseClockPortRunningRole,
    ptpbaseClockPortRunningInterfaceIndex,
    ptpbaseClockPortRunningTransport,
    ptpbaseClockPortRunningEncapsulationType,
    ptpbaseClockPortRunningTxMode, ptpbaseClockPortRunningRxMode,
    ptpbaseClockPortRunningPacketsReceived, and
    ptpbaseClockPortRunningPacketsSent expose a clock port's current
    running status.
    ptpbaseClockPortDSName, ptpbaseClockPortDSPortIdentity,
    ptpbaseClockPortDSlogAnnouncementInterval,
    ptpbaseClockPortDSAnnounceRctTimeout,
    ptpbaseClockPortDSlogSyncInterval,
    ptpbaseClockPortDSMinDelayReqInterval,
    ptpbaseClockPortDSPeerDelayReqInterval,
    ptpbaseClockPortDSDelayMech, ptpbaseClockPortDSPeerMeanPathDelay,
    ptpbaseClockPortDSGrantDuration, and ptpbaseClockPortDSPTPVersion
    expose the values of a clock port's port dataset (portDS).
    ptpbaseClockPortTransDSPortIdentity,
    ptpbaseClockPortTransDSlogMinPdelayReqInt,
    ptpbaseClockPortTransDSFaultyFlag, and
    ptpbaseClockPortTransDSPeerMeanPathDelay expose the values of a
    transparent clock port's port dataset (transparentClockPortDS).

Shankarkumar, et al. Standards Track [Page 60] RFC 8173 PTPv2 MIB June 2017

    ptpbaseClockPortAssociateAddressType,
    ptpbaseClockPortAssociateAddress,
    ptpbaseClockPortAssociatePacketsSent,
    ptpbaseClockPortAssociatePacketsReceived,
    ptpbaseClockPortAssociateInErrors, and
    ptpbaseClockPortAssociateOutErrors expose information about a
    clock port's peer node.
 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 (read) the objects in this MIB module.
 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].
 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
 those objects only to those principals (users) that have legitimate
 rights to access them.

6. IANA Considerations

 The MIB module defined in this document uses the following IANA-
 assigned OBJECT IDENTIFIER value recorded in the "Structure of
 Management Information (SMI) Numbers (MIB Module Registrations)"
 registry:
         Descriptor        OBJECT IDENTIFIER value
         ----------        -----------------------
         ptpbaseMIB        { mib-2 241 }
