Qin

I said that I might look some more and I have.

I still think that you need references for 802.1ad and 802.1ah.  It is not a question of whether or not they are imported, it is where does the reader go to find out more about e.g. QinQ and that needs nailing down to a specific document, and in the case of the IEEE, that needs a date, as you give for 802.1Q.

Talking of which, I find that Rob imports that IEEE module from a different document; 802.1Qcp; um.

[Qin]: Okay, will add all these IEEE related references.
And, in the same vein, I would like a reference for LLDP.

[Qin]:I think it is IEEE 802.1AB and will add.
/defned/defined/
[Qin]: Thanks.
leaf rate
what are the units?
[Qin]: We select Mbps as units and will add.

        leaf maximum-frame-size {
what is a frame, what headers are included and what not?  This is a fraught topic

[Qin]: It is layer 2 frame, it could be Ethernet frame, it could be PPP frame, they are all layer 2 frame.

/ternimation point/termination point/

[Qin]: Fixed, thanks.
     leaf vlan-name {
any constraints on length or character set?  I like them although am conscious that some YANG doctors do not.
[Qin]:Good point, the constraint is 32 characters and will length constraint, thanks.
     leaf encapsulation {
the description exceeds the permissible line length for an RFC
[Qin]:Fixed, thanks.
          type enumeration {
            enum in-use {
             value 0;
again a personal preference - I like to see zero kept for a special purpose (e.g. cannot be determined) unless there is a strong reason to use it (e.g. it is what the protocol has been using for years)
[Qin]:Good, I will skip value 0, thanks!
