Dear Authors, et. al, please kindly consider my notes to the latest version of the draft: - I propose to use the definition proposed in my comments to draft-ietf-lime-yang-oam-model to differentiate between proactive and on-demand OAM. If we agree that on-demand OAM does not require persistent configuration, then for example, ICMP ping should use only RPC, not configuration; - still not clear role of "level" that can have value from the {-1, 0, 1} set.Is it to identify horizontal OAM domains? Why only three, could it be next-to-next domain? - what is "network portion"? Is it "administrative domain"? Please clarify in the text. - what are use cases for the following Test Point locations: - tunnel-location; - ip-prefix-location - route-dist-location - group-ip-address-location - as-number-location - lsp-id-location - system-id-location - opaque-tlv-type - Why only IEEE-1588v2 format supported? Timestamps applied in control plane may be natively in NTP format. - I believe there's error in leaf timestamp-sec { type uint64; description "Absolute timestamp in seconds as per IEEE1588v2."; } leaf timestamp-nanosec { type uint32; description "Fractional part in nanoseconds as per IEEE1588v2."; } since the truncated IEEE-1588v2 timestamp format is 64 bits long and consists of a 32-bit seconds field followed by a 32-bit nanoseconds field, and is the same as the IEEE 1588v1 timestamp format. Network Time Protocol version 4 64-bit timestamp format RFC 5905. This format consists of a 32-bit seconds field followed by a 32-bit fractional seconds field. - Connectivity verification in connectionless network and connectionless OAM has no meaning.
