Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in TCP/IP-based internets.
   In particular, it defines objects for managing networks using
   Precision Time Protocol.

   This memo specifies a MIB module in a manner that is both compliant
   to the SNMPv2 SMI, and semantically identical to the peer SNMPv1
   definitions.

1. Introduction

   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 managed objects used for managing PTP
   devices including the ordinary clock, transparent clock, boundary
   clocks. It is envisioned this MIB will complement other managed
   objects defined to monitor, measure the performance of the PTP
   devices and telecom clocks. Those objects are considered out of scope
   for the current draft.

2. The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o  An overall architecture, described in [RFC 3411].

   o  Mechanisms for describing and naming objects and events for the
      purpose of management.  The first version of this Structure of
      Management Information (SMI) is called SMIv1 and described in
      STD 16 [RFC 1155], STD16 [RFC 1212] and [RFC 1215].
      The second version, called SMIv2, is described in STD 58:
      [RFC 2578], [RFC 2579] and [RFC 2580]

   o  Message protocols for transferring management information.  The
      first version of the SNMP message protocol is called SNMPv1 and
      described in STD 15 [RFC 1157].  A second version of the SNMP
      message protocol, which is not an Internet standards track
      protocol, is called SNMPv2c and described in [RFC 1901] and
      [RFC 1906].  The third version of the message protocol is called
      SNMPv3 and described in STD62: [RFC 3417], [RFC 3412] and [RFC
      3414].

   o  Protocol operations for accessing management information.  The
      first set of protocol operations and associated PDU formats is
      described in STD 15 [RFC 1157].  A second set of protocol
      operations and associated PDU formats is described in STD 62
      [RFC 3416].

   o  A set of fundamental applications described in STD 62 [RFC 3413]
      and the view-based access control mechanism described in STD 62
      [RFC 3415].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (e.g., use of Counter64).  Some machine
   readable information in SMIv2 will be converted into textual
   descriptions in SMIv1 during the translation process.  However, this
   loss of machine readable information is not considered to change the
   semantics of the MIB.

3. Overview

   The objects defined in this MIB are to be used when describing
   Precision Time Protocol (PTPv2).

    DESCRIPTION
        "The MIB module for PTPv2, IEEE Std. 1588(TM) - 2008

        Overview of PTPv2 (IEEE Std. 1588(TM) - 2008)

        [IEEE Std. 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 does not address the
        earlier standard IEEE Std. 1588(TM) - 2002 and PTPv1.

        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 Std. 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. The [IEEE Std. 1588-2008] also defines
        conformance and management capability.
        MIB description

        This MIB is to support the Precision Time Protocol version 2
        (PTPv2, hereafter designated as PTP) features of network element
        system devices.

        IEEE 1588(tm) Edition 2.0 2009-02

        Boundary node clock:
        A clock that has multiple Precision Time Protocol(PTP) ports in
        a domain and maintains the timescale used in the domain. It
        differs from the boundary clock in that the clock roles can
        change.

        As defined in [IEEE Std. 1588-2008]:

        Accuracy:
        The mean of the time or frequency error between the clock under
        test and a perfect reference clock, over an ensemble of
        measurements.  Stability is a measure of how the mean varies
        with respect to variables such as time, temperature, and so on.

        The precision is a measure of the deviation of the error from
        the mean.

        Atomic process:
        A process is atomic if the values of all inputs to the process
        are not permitted to change until all of the results of the
        process are instantiated, and the outputs of the process are
        not visible to other processes until the processing of each
        output is complete.

        Boundary clock:
        A clock that has multiple Precision Time Protocol(PTP) ports in
        a domain and maintains the timescale used in the domain.  It
        may serve as the source of time, i.e., be a master clock, and
        may synchronize to another clock, i.e., be a slave clock.

        Clock:
        A node participating in the Precision Time Protocol (PTP) that
        is capable of providing a measurement of the passage of time
        since a defined epoch.

        Domain:
        A logical grouping of clocks that synchronize to each other
        using the protocol, but that are not necessarily synchronized
        to clocks in another domain.

        End-to-end transparent clock:

Internet-Draft      draft-ietf-tictoc-ptp-mib-00.txt       July 4, 2011


        A transparent clock that supports the use of the end-to-end
        delay measurement mechanism between slave clocks and the master
        clock.  Each node must measure the residence time of PTP event
        messages and accumulate it in Correction Field.

        Epoch:
        The origin of a timescale.

        Event:
        An abstraction of the mechanism by which signals or conditions
        are generated and represented.

        Foreign master:
        An ordinary or boundary clock sending Announce messages to
        another clock that is not the current master recognized by the
        other clock.

        Grandmaster clock:
        Within a domain, a clock that is the ultimate source of time
        for clock synchronization using the protocol.

        Holdover:
        A clock previously synchronized/syntonized to another clock
        (normally a primary reference or a master clock) but now
        free-running based on its own internal oscillator, whose
        frequency is being adjusted using data acquired while it had
        been synchronized/syntonized to the other clock.  It is said to
        be in holdover or in the holdover mode, as long as it is within
        its accuracy requirements.

        Link:
        A network segment between two Precision Time Protocol ports
        supporting the peer delay mechanism of this standard.  The peer
        delay mechanism is designed to measure the propagation time
        over such a link.

        Management node:
        A device that configures and monitors clocks.

        Master clock:
        In the context of a single Precision Time Protocol
        communication path, a clock that is the source of time to which
        all other clocks on that path synchronize.

        Message timestamp point:
        A point within a Precision Time Protocol event message serving
        as a reference point in the message.  A timestamp is defined by
        the instant a message timestamp point passes the reference
        plane of a clock.

        Multicast communication:
        A communication model in which each Precision Time Protocol
        message sent from any PTP port is capable of being received and
        processed by all PTP ports on the same PTP communication path.

        Node:
        A device that can issue or receive Precision Time Protocol
        communications on a network.

        One-step clock:
        A clock that provides time information using a single event
        message.

        On-path support:
        Indicates that each node in the synchronization chain from
        master to slave can support [IEEE Std. 1588-2008].

        Ordinary clock:
        A clock that has a single Precision Time Protocol port in a
        domain and maintains the timescale used in the domain.  It may
        serve as a source of time, i.e., be a master clock, or may
        synchronize to another clock, i.e., be a slave clock.

        Parent clock:
        The master clock to which a clock is synchronized.

        Peer-to-peer transparent clock:
        A transparent clock that, in addition to providing Precision
        Time Protocol event transit time information, also provides
        corrections for the propagation delay of the link connected to
        the port receiving the PTP event message.  In the presence of
        peer-to-peer transparent clocks, delay measurements between
        slave clocks and the master clock are performed using the
        peer-to-peer delay measurement mechanism.

        Phase change rate:
        The observed rate of change in the measured time with respect
        to the reference time.  The phase change rate is equal to the
        fractional frequency offset between the measured frequency and
        the reference frequency.

        PortNumber:
        An index identifying a specific Precision Time Protocol port on
        a PTP node.

        Primary reference:
        A source of time and or frequency that is traceable to
        international standards.

        part of the operation of the peer-to-peer delay mechanism.

        Synchronized clocks:
        Two clocks are synchronized to a specified uncertainty if they
        have the same epoch and their measurements of the time of a
        single event at an arbitrary time differ by no more than that
        uncertainty.

        Syntonized clocks:
        Two clocks are syntonized if the duration of the second is the
        same on both, which means the time as measured by each advances
        at the same rate. They may or may not share the same epoch.

        Timeout:
        A mechanism for terminating requested activity that, at least
        from the requester's perspective, does not complete within the
        specified time.

        Timescale:
        A linear measure of time from an epoch.

        Traceability:
        A property of the result of a measurement or the value of a
        standard whereby it can be related to stated references,
        usually national or international standards, through an
        unbroken
        chain of comparisons all having stated uncertainties.

        Translation device:
        A boundary clock or, in some cases, a transparent clock that
        translates the protocol messages between regions implementing
        different transport and messaging protocols, between different
        versions of IEEE Std 1588-2008/IEC 61588:2009, or different
        Precision Time Protocol profiles.

        transparent clock:
        A device that measures the time taken for a Precision Time
        Protocol event message to transit the device and provides this
        information to clocks receiving this PTP event message.

        Two-step clock:
        A clock that provides time information using the combination of
        an event message and a subsequent general message.

5. Security Considerations

   This MIB contains readable objects whose values provide information
   related to PTP objects. While unauthorized access to the readable
   objects is relatively innocuous, unauthorized access to the write-
   able objects could cause a denial of service, or could cause
   unauthorized creation and/or manipulation of tunnels. Hence, the
   support for SET operations in a non-secure environment without proper
   protection can have a negative effect on network operations.

   SNMPv1 by itself is such an insecure environment.  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 SET (change/create/delete) the objects in this MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model [RFC 3414] and the View-based Access
   Control Model [RFC 3415] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to this MIB, is properly configured to give
   access to those objects only to those principals (users) that have
   legitimate rights to access them.

6. IANA Considerations

   To be added.
