    Integrated Services Management Information Base using SMIv2

Status of this Memo

 This document specifies an Internet standards track protocol for the
 Internet community, and requests discussion and suggestions for
 improvements.  Please refer to the current edition of the "Internet
 Official Protocol Standards" (STD 1) for the standardization state
 and status of this protocol.  Distribution of this memo is unlimited.

Abstract

 This memo defines a portion of the Management Information Base (MIB)
 for use with network management protocols in TCP/IP-based internets.
 In particular, it defines objects for managing the the interface
 attributes defined in the Integrated Services Model.  Comments should
 be made to the Integrated Services Working Group, int-serv@isi.edu.

1. The SNMPv2 Network Management Framework

 The SNMPv2 Network Management Framework consists of four major
 components.  They are:
 o    RFC 1441 which defines the SMI, the mechanisms used for
      describing and naming objects for the purpose of
      management.
 o    STD 17, RFC 1213 defines MIB-II, the core set of managed
      objects for the Internet suite of protocols.
 o    RFC 1445 which defines the administrative and other
      architectural aspects of the framework.
 o    RFC 1448 which defines the protocol used for network
      access to managed objects.
 The Framework permits new objects to be defined for the purpose of
 experimentation and evaluation.

1.1. Object Definitions

 Managed objects are accessed via a virtual information store, termed
 the Management Information Base or MIB.  Objects in the MIB are
 defined using the subset of Abstract Syntax Notation One (ASN.1)
 defined in the SMI.  In particular, each object type is named by an
 OBJECT IDENTIFIER, an administratively assigned name.  The object
 type together with an object instance serves to uniquely identify a
 specific instantiation of the object.  For human convenience, we
 often use a textual string, termed the descriptor, to refer to the
 object type.

2. Overview

2.1. Textual Conventions

 Several new data types are introduced as a textual convention in this
 MIB document.  These textual conventions enhance the readability of
 the specification and can ease comparison with other specifications
 if appropriate.  It should be noted that the introduction of the
 these textual conventions has no effect on either the syntax nor the
 semantics of any managed objects.  The use of these is merely an

Baker, et. al. Standards Track [Page 2] RFC 2213 Integrated Services MIB using SMIv2 September 1997

 artifact of the explanatory method used.  Objects defined in terms of
 one of these methods are always encoded by means of the rules that
 define the primitive type.  Hence, no changes to the SMI or the SNMP
 are necessary to accommodate these textual conventions which are
 adopted merely for the convenience of readers and writers in pursuit
 of the elusive goal of clear, concise, and unambiguous MIB documents.

2.2. Structure of MIB

 The MIB is composed of the following sections:
      Integrated Services
           Interface Attributes Table
           Interface Flow Table

      DESCRIPTION
         "The Session  Number  convention  is  used  for
         numbers  identifying  sessions or saved PATH or
         RESV information. It is a number in  the  range
         returned  by  a TestAndIncr variable, having no
         protocol meaning whatsoever but serving instead
         as simple identifier.
         The alternative was a very complex instance  or

         ject,  as  defined  in  the RSVP specification.
         This value  determines  the  lengths  of  octet

         is  not  used, the value should be of length 0.
         This pair, when coupled with the  IP  Addresses

4. Security Considerations

 The use of an SNMP SET results in an RSVP or Integrated Services
 reservation under rules that are different compared to if the
 reservation was negotiated using RSVP. However, no other security
 considerations exist other than those imposed by SNMP itself.
