Abstract
This memo recommends that RFC 1643 be reclassified as an Historic
document and provides the supporting motivation for that
recommendation.
1. Details
STD 50, RFC 1643 [RFC1643], "Definitions of Managed Objects for the
Ethernet-like Interface Types", and its SMIv2 equivalent, RFC 1650
[RFC1650], are applicable to half-duplex 10 Mb/s Ethernet interfaces
only. Subsequent to the 1994 publication of these documents, 100
Mb/s, 1000 Mb/s, and 10 Gb/s Ethernet interface types have been
developed, and full-duplex operation at 10 Mb/s has been
standardized. Updates to RFC 1650 have been produced to accommodate
these new technologies [RFC2358] [RFC2665] [RFC2666] [RFC3635].
These updates define new MIB objects to supplement those defined in
RFC 1643 and RFC 1650 and in addition deprecate some of the objects
in RFC 1643 and RFC 1650 that are no longer considered useful. They
also levy a requirement for implementations of the EtherLike-MIB to
support the MAU-MIB [RFC2239] [RFC2668] [RFC3636] as well.

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 [RFC3635] and RFC 2666 [RFC2666],
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 [RFC2020] 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 [RFC2358], RFC 2665 [RFC2665], and RFC 3635 [RFC3635] 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 [RFC2720] 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.

3. Security Considerations
Reclassification of RFC 1643 will not, in and of itself, have any
effect on the security of the Internet.
