Here is the AD review of draft-ietf-lime-yang-connection-oriented-oam-model. Sorry for the delay.

- Please use the latest Security Considerations template.
It was until recently at this location: https://www.ietf.org/iesg/directorate/yang-doctors.html
But not available any longer. I'm in discussion about it.

- you want to refer to RFC8174 instead of RFC2119
   The keywords "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.
- I like the section 4.x that explains part of the tree, with logical sections.

- you want to use the YANG tree diagrams in draft-ietf-netmod-yang-tree-diagrams-04
I advice a section similar to https://tools.ietf.org/html/draft-ietf-netmod-rfc7223bis-03#section-1.3

- you are NMDA compliant. I guess you want a sentence such as:
   The YANG model in this document conforms to the Network Management
   Datastore Architecture defined in I-D.ietf-netmod-revised-datastores.
Again, take https://tools.ietf.org/html/draft-ietf-netmod-rfc7223bis-03 as an example

- For the YANG specifics, I'm waiting for Carl Moberg YANG doctor review.
This should not prevent starting the IETF LC if Carl's feedback doesn't come soon.


Editorial:

- there are a few idnits. See https://www.ietf.org/tools/idnits?url=https://www.ietf.org/archive/id/draft-ietf-lime-yang-connection-oriented-oam-model-03.txt
For ex, "3 instances of too long lines in the document"

- 
   As an example, consider a scenario where Loopback from device A to
   Device B fails.
Do you mean?
   As an example, consider a scenario where connectivity from device A loopback to
   device B fails.
Along the same lines, what does the following mean?
   Upon detecting the Loopback failures
- indpendent => independent
Note: multiple instances

-   identity rdi {
    base defect-types;
    description
      "Indicates the aggregate health of the remote
       Maintenance End Points (MEPs). ";
  }

It would be best if the identity name would either be meaningful or be explained in the description

- similar remark for
  typedef interval{
    type decimal64{
    fraction-digits 2;
   }
   units "milliseconds";
    description
    "Interval between packets in milliseconds.
    0 means no packets are sent.";
  }

Do you want to say to at least say time-interval?

- similar remark (or I guess this is a generic comment):
  grouping cos {
    description
    "Priority used in transmitted packets; for example, in the
     EXP field in MPLS-TP.";
    leaf cos-id {
     type uint8;
     description
     "Class of service.";
    }
  }

In the grouping description, you at least want to mention Class of Service.


- no need to list the WG chairs in the YANG module, as mentioned in https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-16#appendix-C

- 
  identity name-format {
    description
    "This defines the name format, IEEE 8021ag CFM defines varying
    styles of names. It is expected name format as an identity ref
    to be extended with new types.";
  }

Name format of? I guess generic.
Please review the YANG module description.
For example:
    leaf md-name-format {
      type identityref {
        base name-format;
      }
      description
        "Name format.";
    }

At least mention the Management Domain Name Format. 

- 
	The RPC model facilitates issuing commands to a NETCONF server 

It could be RESTCONF as well. It's best to mention "server"

Overall, the document is in reasonable shape but needs more attention around one fundamental aspect, and a short list of minor issues. My understanding is that this module is intended to be implemented as a network service model, per the module classification RFC (RFC8199). But e.g. the ‘mip' list has a key 'interface' of type 'if:interface-ref'. That type is defined in ietf-interfaces to be a leafref with path "/if:interfaces/if:interface/if:name” assuming that the module context is a single network element. This seems self-contradicting and needs to be resolved. I would suggest running the YANG module through 'pyang -f yang' to provide consistent formatting of the module. I think it would also be worth considering putting the content in the canonical order. E.g. the location of the description statement in the mip-address grouping makes it hard to read. The 'session' list is 'ordered-by user', but does not provide any description or explanation to the meaning of the order. The content of the description strings are in need of language fixes.

This draft is a work item of the Layer Independent OAM Management in the Multi-Layer Environment WG of the IETF. Title : Generic YANG Data Model for Connection Oriented Operations, Administration, and Maintenance(OAM) protocols Authors : Deepak Kumar Qin Wu Michael Wang Filename : draft-ietf-lime-yang-connection-oriented-oam-model-04.txt Pages : 53 Date : 2018-01-30 Abstract: This document presents a base YANG Data model for connection oriented OAM protocols. It provides a technology-independent abstraction of key OAM constructs for such protocols. The model presented here can be extended to include technology specific details. This guarantees uniformity in the management of OAM protocols and provides support for nested OAM workflows (i.e., performing OAM functions at different levels through a unified interface) The YANG model in this document conforms to the Network Management Datastore Architecture defined in [I-D.ietf-netmod-revised-datastores]. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-lime-yang-connection-oriented-oam-model/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-lime-yang-connection-oriented-oam-model-04 https://datatracker.ietf.org/doc/html/draft-ietf-lime-yang-connection-oriented-oam-model-04 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-lime-yang-connection-oriented-oam-model-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Please kindly consider my comments below. - this document introduces YANG data model of connection-oriented OAM protocols. I couldn't find the definition or reference to normative definition of the connection-oriented OAM. As we've discussed, I believe that the definition of the channel forwarding in G.800 in section 6.3.1, specifically for connection-oriented packet switching, is the one we can use similarly to the definition of connectionless OAM in draft-ietf-lime-yang-connectionless-oam. And the fact that both documents share one source of definitions, in my view, is advantage of consistent dictionary. - "This is the base identy of technology types which are TRILL,MPLS-TP,vpls etc" Had VPLS been characterized as CO-PS? Not to get into the discussion, perhaps stop after MPLS-TP be acceptable. And I encourage to omit other references to VPLS in the document: - "... or for VPLS this can be per VPLS instance [RFC6136]." - " a VRF for VPLS," - what is the benefit to have specific ipv4-address and ipv6-address in 'choice mep-address' rather than ip-address imported from inet:ip-address? - I think that 'leaf packet-size' is related to packet padding, not the actual size of the test packet as there's always minimum size determined by the corresponding technology and thus the packet size cannot be smaller than the minimum size of, for example, LBM. Current range for the leaf packet-size in rpc continuity-check is 0...10000 and in rpc continuity-verification the range is 64 ... 10000 (why such inconsistency?). Test packet of 0 bytes doesn't seem practical while test packet with 0 bytes of padding/payload does. And though we'd like to use default for zero-touch (almost zero-touch), this is very technology-specific parameter (compare Ethernet LBM and MPLS LSP Ping). Nits: - s/interface)/interface)./ - consistency in using YANG vs. Yang throughout the document should be achi= eved. - s/../maintenance-domain]/co-oam:mas/co-oam:ma[/../maintenance-domain]/co-= oam:mas/co-oam:ma/ - s/CoS field in MPLS-TP/TC field in MPLS-TP/ Regards, Greg On Tue, Jan 30, 2018 at 12:58 AM, wangzitao wrote: > Hi WG, > > This version addressed the issues arose by AD review and Yangdoctors earl= y review. > More details please review the document. > > Best Regards! > -Michael > > -----=E9=82=AE=E4=BB=B6=E5=8E=9F=E4=BB=B6----- > =E5=8F=91=E4=BB=B6=E4=BA=BA: Lime [mailto:lime-bounces@ietf.org] =E4=BB= =A3=E8=A1=A8 internet-drafts@ietf.org > =E5=8F=91=E9=80=81=E6=97=B6=E9=97=B4: 2018=E5=B9=B41=E6=9C=8830=E6=97=A5 = 16:44 > =E6=94=B6=E4=BB=B6=E4=BA=BA: i-d-announce@ietf.org > =E6=8A=84=E9=80=81: lime@ietf.org > =E4=B8=BB=E9=A2=98: [Lime] I-D Action: draft-ietf-lime-yang-connection-or= iented-oam-model-04.txt > > > A New Internet-Draft is available from the on-line Internet-Drafts direct= ories. > This draft is a work item of the Layer Independent OAM Management in the = Multi-Layer Environment WG of the IETF. > > Title : Generic YANG Data Model for Connection Oriented= Operations, Administration, and Maintenance(OAM) protocols > Authors : Deepak Kumar > Qin Wu > Michael Wang > Filename : draft-ietf-lime-yang-connection-oriented-oam-mo= del-04.txt > Pages : 53 > Date : 2018-01-30 > > Abstract: > This document presents a base YANG Data model for connection oriented > OAM protocols.
