Start with the current ietf-ptp.yang, but change - module name and namespace, using vendor prefix 'ni-' - followed by likely names from the IEEE working group. - Retain the prefix from ietf-ptp.yang (ptp). - 2.

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).
