Abstract

  This memo describes Textual Conventions and OBJECT-IDENTITIES used
  for managing ATM-based interfaces, devices, networks and services.

1.  Introduction

  This memo describes Textual Conventions and OBJECT-IDENTITIES used
  for managing ATM-based interfaces, devices, networks and services.






Noto, et. al.               Standards Track                     [Page 1]

RFC 2514             ATM TCs and OBJECT-IDENTITIES         February 1999


  When designing a MIB module, it is often useful to define new types
  similar to those defined in the SMI.  In comparison to a type defined
  in the SMI, each of these new types has a different name, a similar
  syntax, but a more precise semantics.  These newly defined types are
  termed textual conventions, and are used for the convenience of
  humans reading the MIB module.  This is done through Textual
  Conventions as defined in RFC1903 [1].  It is the purpose of this
  document to define the set of textual conventions available to ATM
  MIB modules.

  When designing MIB modules, it is also often useful to register
  further properties with object identifier assignments so that they
  can be further used by other MIB modules.  This is done through the
  OBJECT-IDENTITY macro defined in RFC1902 [2].  This document defines
  OBJECT-IDENTITIES available to ATM MIB modules.

  Note that for organizational purposes OBJECT IDENTITIES previously
  defined in RFC1695 have been moved to this specification and no
  longer appear in the revision of RFC1695 [3]. However, the original
  OBJECT IDENTIFIERs have been preserved.

  For an introduction to the concepts of ATM connections, see [3].
