    P-MAC does not occur in the draft; I think you mean B-MAC. C-MAC is
    Customer/Client MAC address and B-MAC is Backbone MAC address as
    further specified in RFC 7623. These can be spelled out and a
    reference to RFC 7623 (which is already listed in the References for
    the draft) added.

Yes, I meant B-MAC and C-MAC . And yes spelling out and reference will be helpful.

    OK, except I think it should be spelled out on first use in 2.1. But
    certainly the wording should be parallel in these cases.

    Yes, it is intended to be reference to IEEE Std 802.3-2015 (or
    whatever the most recent version is). I have no idea why the nits
    checker doesn't complain about this being missing from the References
    sections. If it did, it would already have been fixed. Since this is
    just an example, I think it can be added as an Informational
    Reference.
OK.

    Would it be sufficient to add an entry in the terminology section
    (1.3) and a reference to RFC 6623?

Yes, that will do.

    Sure.

    These are examples.

In that case, I would suggest to rephrase the sentence to be clear that those are examples. 

    Thanks,
