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].

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).
Shankarkumar, et al. Standards Track [Page 59]RFC 8173 PTPv2 MIB June 2017
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:
