Re: Last Call: <draft-ietf-ancp-protocol-15.txt> (Protocol for Access Node Control Mechanism in Broadband Networks) to Proposed Standard

Hello,

Let me comment the IANA consideration section of this document.

   IANA is requested to implement the following modification to the
    General Switch Management Protocol version 3 (GSMPv3) Result Type
    Name Space registry:

            +--------------+-----------------------+-----------+
            | Result Value | Result Type Name      | Reference |
            +--------------+-----------------------+-----------+
            | 0            | Ignore (was Reserved) | RFCXXXX   |
            +--------------+-----------------------+-----------+
In the registry you are modifying the value 0 is now Reserved. RFC 5226 says:

       Reserved:  Not to be assigned.  Reserved values are held for
             special uses, such as to extend the namespace when it become
             exhausted.  Reserved values are not available for general
             assignment.
Therefore it is not permitted to register reserved values. Moreover, this document says that you shouldn't have mentioned exact values you want to register - see Section 5.1 of RFC 5226 (the same applies to another registry modifications, as one might notice).

Next,

    IANA is requested to create a new ANCP Port Management Function Name
    registry, with the following initial entries.  Additions to this
    registry will be by IETF Consensus.
You should have here the reference to RFC 5226, shouldn't you? (This also applies to other registry descriptions)
   Values may range from 0 to 255.

      [ . . . ]

What is more,

IANA is requested to create a new ANCP Version registry, with
    additions by IETF consensus.  The initial entries are as follows:

            +---------+-------------+--------------+-----------+
            | Version | Sub-Version | Name         | Reference |
            +---------+-------------+--------------+-----------+
            | 3       | 1           | Pre-standard |           |
            | 3       | 2           | ANCPv1       | RFCXXXX   |
            +---------+-------------+--------------+-----------+
This description is obviously missing the definition of values' format, or at least key values.

Moreover,

IANA is requested to create a new ANCP Command Code registry, with
    additions by IETF Consensus.  The initial entry is as follows:

      +--------------------+-----------------------------+-----------+
      | Command Code Value | Command Code Directive Name | Reference |
      +--------------------+-----------------------------+-----------+
      | 0                  | Reserved                    | RFCXXXX   |
      +--------------------+-----------------------------+-----------+
The same as above applies. Moreover, does this registry consists of only one values, that is reserved and therefore cannot be assigned, per RFC 5226? This is at least impossible.

Finally,
IANA is requested to create a new ANCP TLV Type registry, with
    additions by IETF Consensus.  Values may range from 0x0000 to 0xFFFF.
    New assignments should be in the range of values from 0x0100 upwards.
    The initial entries are as follows:
Here you should have mentioned that values are hexadecimal, for clarity.

Thank you for considering my comments in advance.

All the best,
Mykyta Yevstifeyev
