IEEE Std 1588 specifies the Precision Time Protocol (PTP). The nodes in this YANG module are designed for compatibility with ietf-ptp.yang, the YANG data model for IEEE Std 1588-2008, as specified in IETF RFC 8575. NOTE regarding default value: PTP's concept of 'initialization value' is analogous to YANG's concept of a 'default value'. According to 8.1.3.4 of IEEE Std 1588-2019, the initialization value for configuration is specified in IEEE Std 1588, but that value can be overridden by a PTP Profile specification, or by the product that implements PTP. This makes it challenging to repeat the specification of initialization value using a YANG 'default' statement, because there is no straightforward mechanism for a PTP Profile's (or product's) YANG module to import this module and override its YANG default. Since a YANG management client can read the default value from the operational datastore, there is no need to re-specify the default in YANG. The implementer of PTP refers to the relevant PTP specifications for the default (not YANG modules). Therefore, this YANG module avoids use of the YANG 'default' statement. NOTE regarding IEEE Std 1588 classification: 8.1.2 of IEEE Std 1588-2019 specifies a classification of each data set member, which corresponds to a leaf in YANG. The relationship between 1588 classification and YANG 'config' (i.e., whether the leaf is read-write) is: - 1588 static: The leaf is 'config false' (read-only). - 1588 configurable: The leaf is 'config true', which is the default value for a YANG leaf. - 1588 dynamic: A judgement is made on a member-by-member basis. If the member corresponds to the first item of 8.1.2.1.2 of IEEE Std 1588-2019 (i.e., value from protocol only, such as log of protocol behavior), the YANG leaf is 'config false'. Otherwise, the member's value can be provided by an entity outside PTP (e.g., NETCONF or RESTCONF client), and therefore the YANG leaf is 'config true'. NOTE regarding terminology (two YANG modules): To accommodate the need by some organizations to use the original terminology specified by IEEE Std 1588, and the need by some other organizations to use the alternative terminology specified in 4.4 of IEEE Std 1588g-2022, two YANG modules are provided by IEEE Std 1588e (MIB and YANG Data Models). For a detailed explanation, see 15.4.2.11 of IEEE Std 1588e. This module uses the alternative terminology specified in 4.4 of IEEE Std 1588g-2022 (timeTransmitter/timeReceiver)."; revision "2023-08-14" { description "Initial revision."; reference "IEEE Std 1588e-2024, IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems - MIB and YANG Data Models."; } feature fault-log { description "Logging of faults detected in the PTP Instance."; reference "8.2.6 of IEEE Std 1588-2019"; } feature unicast-negotiation { description "Unicast negotiation conducted through use of TLVs."; reference "16.1 of IEEE Std 1588-2019"; } feature path-trace { description "Use of the PATH_TRACE TLV for tracing the route of a PTP Announce message through the PTP Network."; reference "16.2 of IEEE Std 1588-2019"; } feature alternate-timescale { description "The transmission of an ALTERNATE_TIME_OFFSET_INDICATOR TLV entity from the Grandmaster PTP Instance may indicate the offset of an alternate timescale from the timescale in use in the domain."; reference "16.3 of IEEE Std 1588-2019"; } feature holdover-upgrade { description "A holdover-upgradable PTP Instance can potentially become the Grandmaster PTP Instance in the event the previous Grandmaster PTP Instance is disconnected or its characteristics degrade."; reference "16.4 of IEEE Std 1588-2019"; } feature cmlds { description "The Common Mean Link Delay Service (CMLDS) is an optional service that enables any PTP Port that would normally obtain the value of a link's <meanLinkDelay> and <neighborRateRatio> using the peer-to-peer method to instead obtain these values from this optional service.

The list is organized as follows: - 97 15-minute measurement records, the current record at index 0, followed by the most recent 96 records. - 2 24-hour measurement records, the current record at index 97, and the previous record at index 98. If a record is not implemented for a specific index, management does not return the record. For example, if only four 15-minute periods are implemented, a management request for performance-monitoring-port-ds/record-list[6] returns an error. If only some of the data is reported, the same index values are used. As an example, if only the 24-hour statistics are accessed, the indexes are still 97 and 98. If a specific parameter (e.g. sync-tx) is not implemented, management does not return the parameter (i.e., error). Parameters that are invalid (not measured correctly) shall be indicated with with the value zero, indicating that nothing was counted. Each counter in the record shall be initialized to zero at the start of a new 15-minute and 24-hour interval."; reference "J.5.2.2 of IEEE Std 1588-2019"; leaf index { type uint16; description "Index to each record in the list (0-99)."; } leaf pm-time { type yang:timestamp; description "Time of the beginning of the measurement record.
