Capwap Mailing List: Issue 166: Various IANA Issues

[Pat Calhoun (pacalhou) (pcalhoun]

Pasi's comment was:

   Section 15: Even if the well-known port numbers have already been
   allocated, it would be good to say they've been 
   allocated by IANA.

   Section 15: needs to cite RFC 5226 for the "Standards Action" policy.
   
   Section 15: RFC 5226 says that documents requesting creation of new
   registries MUST include certain instructions for 
   IANA (RFC 5226 Section 4.2) -- many of the details are currently
missing.

15.  IANA Considerations

   This section details the actions to be taken by IANA during the
   publication of the specification.  There are numerous registries that
   need to be created, and the contents, document action (see [RFC5226],
   and registry format are all included below.  Note that in cases where
   bit fields are referred to, the bit numbering is left to right, where
   the leftmost bit is labelled as bit zero (0).

15.1.  Multicast Address

   This document requires a new organization local multicast address
   called the "All ACs multicast address" from the IPv6 multicast
   address registry [to be removed upon publication
   http://www.iana.org/assignments/ipv6-multicast-addresses].  The new
   multicast address is to be inserted in Section 3.3.

15.2.  UDP Port

   This document requires a two UDP Ports organization local multicast
   address from the registered port numbers registry [to be removed upon
   publication http://www.iana.org/assignments/port-numbers].  The new
   UDP Ports numbers have already been assigned and can be found in
   Section 3.1.  The following values are being registered:

Keyword         Decimal    Description                     References
-------         -------    -----------                     ----------

15.3.  CAPWAP Message Types

   The Message Type field in the CAPWAP header (see Section 4.5.1.1) is
   used to identify the operation performed by the message.  There are
   multiple namespaces, which is identified via the first three octets
   of the field containing the IANA Enterprise Number [RFC5226].

   IANA will create and maintain the CAPWAP Message Types registry for
   all message types whose Enterprise Number is set to zero (0).  The
   namespace is 32 bits (0-4294967295), where the value of zero (0) is
   reserved and must not be assigned.  The values one (1) through 26 are
   allocated in this specification, and can be found in Section 4.5.1.1.
   Any new assignments of a CAPWAP Message Type, whose Enterprise Number
   is set to zero (0) requires a Standards Action.  The format of the
   registry to be maintained by IANA has the following format:

           CAPWAP Control Message           Message Type     Reference

15.4.  CAPWAP Header Flags

   The Flags field in the CAPWAP header (see Section 4.3) is 9 bits in
   length and is used to identify any special treatment related to the
   message.  This specification defines bits zero (0) through five (5),
   while bits six (6) through eight (8) are reserved.  There are
   currently three unused, reserved bits which are managed by IANA and
   whose assignment requires a Standard Action.  IANA will create the
   CAPWAP Header Flags registry, whose format is:

           Flag Field Name                   Bit Position    Reference

15.5.  CAPWAP Control Message Flags

   The Flags field in the CAPWAP Control Message header (see
   Section 4.5.1.4) is used to identify any special treatment related to
   the control message.  There are currently eight (8) unused, reserved
   bits.  These bits whose assignment is managed by IANA and requires a
   Standards Action.  IANA will create the CAPWAP Control Message Flags
   registry, whose format is:

           Flag Field Name                   Bit Position    Reference

15.6.  CAPWAP Control Message Type

   The Type field in the CAPWAP Control Message header (see Section 4.6)
   is used to identify the data being transported.  The namespace is 32
   bits (0-4294967295), where the value of zero (0) is reserved and must
   not be assigned.  The values one (1) through 52 are allocated in this
   specification, and can be found in Section 4.5.1.1.  This namespace
   is managed by IANA and assignments require a Standards Action.  IANA
   will create the CAPWAP Control Message Type registry, whose format
   is:

           CAPWAP Message Element           Type Value       Reference

15.7.  Wireless Binding Identifiers

   The Wireless Binding Identifier (WBID) field in the CAPWAP header
   (see Section 4.3) is used to identify the wireless technology
   associated with the packet.  Due to the limited address space
   available, a new WBID request requires Standards Action.
