One more comment with the structure of the YANG Module: The data model specified used several "enum" type, making it very difficult to expand in the future. For example, "delay-mechanism-enumeration" currently has "e2e", "p2P", and "disabled". If you want to add one more value, the new data model is not backward compatible. Should consider using "identity" and use "identityref". When expand in the future, data model is still backward compatible.

Reviewer: Linda Dunbar Review Date: 2018-09-04 IETF LC End Date: 2018-09-07 IESG Telechat date: Not scheduled for a telechat Summary: This document specify the YANG data model for IEEE1588-2008. The document is written very clear. I have some questions, such as What is the relationship between Current-DS and Default-DS? It seems to be that the "default-ds" has most of the information for the clock. Is Current-ds simply supplement?
