Summary: This draft is almost ready for publication as Standard track RFC.

 

 

Major issues:

 

Minor issues:

 

1.       I had some problem understanding the "location" leaf. Section 3.2
has it as a string and says that "The device uses the location string to
identify the physical or logical entity that the configuration applies to".
I am not sure how you identify physical location having no definition of the
mapping.

The sentence just before the quoted one above says:

  "The format of this string is device- and type-dependent."

and then the text says:

  "How a client can learn which types and locations are present on a
  certain device is outside the scope of this document."

So the exact procedure is currently left to the vendors, but may be
standardized in a future document (if possible...)

I saw the examples in Appendix E and it looked more to me as
logical mapping but not physical since it attaches a name to something in
the device but I am not clear how you know what it is physically in the
device. If the name 0-n or n/m are real physical entities, I think that it
should be specified some place. 

 

 

Nits/editorial comments:

1.    In the introduction section maybe add to the first sentence a
reference to RFC6244 with some text.

Ok, this probably makes sense.  I will check w/ the WG and other
documents.

2.    In section 2 are the" must" and "should"  used as described in
RFC2119, if yes need capital letters

Seciton 2 is more of a background, non-normative section.  It lists
some of the design objectives.

3.    In section 3.1 "It is optional in the data model,  but if the type
represents a physical interface, it is mandatory", suggest having RFC2119
language "It is OPTIONAL in the data model,  but if the type represents a
physical interface, it is MUST be specified"

I think the first one should not be OPTIONAL, but the second one is
correct.  So I suggest this:

  It is defined as being optional in the data model, but if the type
  represents a physical interface, it MUST be specified.
