       Guidelines and Registration Procedures for Interface Types
                       draft-thaler-iftype-reg-02

Abstract

   The registration and use of interface types ("ifType" values)
   predated the use of IANA Considerations sections and YANG modules,
   and so confusion has arisen about the interface type allocation
   process.  This document provides updated guidelines for the
   definition of new interface types, for consideration by those who are
   defining, registering, or evaluating those definitions.

1.  Introduction

   The IANA IfType-MIB was originally defined in [RFC1573] as a separate
   MIB module together with the Interfaces Group MIB (IF-MIB) module.
   The IF-MIB module has since been updated and is currently specified
   in [RFC2863], but this latest IF-MIB RFC no longer contains the IANA
   IfType-MIB.  Instead, the IANA IfType-MIB is now maintained as a
   separate module.  Similarly, [RFC7224] created an initial IANA
   Interface Type YANG Module, and the current version is maintained by
   IANA.

   The current IANA IfType registries are in [iana-if-type],
   [IANAifType-MIB], and [ifType].

   Although the ifType registry was originally defined in a MIB module,
   the assignment and use of interface type values are not tied to MIB
   modules or any other management mechanism.  Interface type values can
   be used as values of data model objects (MIB objects, YANG objects,
   etc.), as parts of a unique identifier of a data model for a given
   interface type (e.g., in an OID), or simply as values exposed by
   local APIs or UI on a device.
