  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, [email protected].

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.

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.

Overview

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

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.

Structure of MIB

The MIB is composed of the following sections:

    Integrated Services
         Interface Attributes Table
         Interface Flow Table

-- Textual Conventions --

SessionNumber ::= TEXTUAL-CONVENTION
    STATUS   current
    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
       instance object that became unwieldy."
   SYNTAX   INTEGER (0..2147483647)
Protocol ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "d"
    STATUS   current
    DESCRIPTION
       "The value of the IP Protocol field  of  an  IP
       Datagram  Header.  This identifies the protocol
       layer above IP.  For example, the  value  6  is
       used  for TCP and the value 17 is used for UDP.
       The values of this field are defined in the As-
       signed Numbers RFC."
   SYNTAX   INTEGER (1..255)
SessionType ::= TEXTUAL-CONVENTION
    STATUS   current
    DESCRIPTION
       "The value of the C-Type field of a Session ob-
       ject,  as  defined  in  the RSVP specification.
       This value  determines  the  lengths  of  octet
       strings  and use of certain objects such as the
       'port' variables. If the C-Type  calls  for  an
       IP6  address, one would expect all source, des-
       tination, and next/previous hop addresses to be
       16  bytes long, and for the ports to be UDP/TCP
       port numbers, for example."
   SYNTAX   INTEGER (1..255)
Port ::= TEXTUAL-CONVENTION
    DISPLAY-HINT "d"
    STATUS   current
    DESCRIPTION
       "The value of the UDP or TCP Source or Destina-
       tion  Port field, a virtual destination port or
       generalized port identifier used with the IPSEC
       Authentication Header or Encapsulating Security
       Payload, or other session discriminator.  If it
       is  not  used, the value should be of length 0.
       This pair, when coupled with the  IP  Addresses
       of the source and destination system and the IP
       protocol  field,  uniquely  identifies  a  data
       stream."

    STATUS   current
    DESCRIPTION
       "The rate, in bits/second, that data  may  move
       in  the context.  Applicable contexts minimally
       include the speed of an  interface  or  virtual
       circuit, the data rate of a (potentially aggre-
