Applicability Statement for Reclassification of RFC 1643 to Historic Status



Alternative Format: Original Text Document



RFC 3638              RFC 1643 to Historic Status         September 2003


   RFC 1643 is an obsolete specification, overtaken by events.  Its
   SMIv2 equivalent, RFC 1650, was officially retired in 1998.  New
   implementations -- even those that support only half-duplex 10 Mb/s
   interfaces -- should comply with in the latest version of the
   specification, currently RFC 3635 [RFC 3635] and RFC 2666 [RFC 2666],
   instead of RFC 1643.  It is therefore recommended that RFC 1643 be
   reclassified as an Historic document.

2.  Effect on Other Standards Track Documents

   Reclassification of RFC 1643 will have no impact on the status of any
   standards track RFC because no standards track RFC cites it as a
   normative reference.  An RFC content search made with the tools
   available at http://www.rfc-editor.org reveals the following
   standards track documents that cite RFC 1643:

      Document               Title
      --------               -----

      RFC 2020         IEEE 802.12 Interface MIB

      RFC 2358         Definitions of Managed Objects for the
                       Ethernet-like Interface Types

      RFC 2665         Definitions of Managed Objects for the
                       Ethernet-like Interface Types

      RFC 2720         Traffic Flow Measurement: Meter MIB

      RFC 3635         Definitions of Managed Objects for the
                       Ethernet-like Interface Types

   RFC 2020 [RFC 2020] contains DOT12-IF-MIB, which is the MIB module for
   managing IEEE 802.12 100VG-AnyLAN interfaces.  It refers to RFC 1643
   in the context of an admonition not to implement the EtherLike-MIB
   for any interface where the DOT12-IF-MIB is implemented.

   RFC 2358 [RFC 2358], RFC 2665 [RFC 2665], and RFC 3635 [RFC 3635] all
   contain updated versions of the EtherLike-MIB.  They refer to RFC
   1643 in the context of explaining the history of the EtherLike-MIB,
   and the citation in RFC 3635 is explicitly listed as a non-normative
   reference.

   RFC 2720 [RFC 2720] contains the FLOW-METER-MIB.  It refers to RFC
   1643 only in an ASN.1 comment in the MIB module.  Omission of that
   comment would not preclude correct implementation of the MIB module.

   Clearly, none of these citations are normative.
