Remote Network Monitoring MIB Protocol Identifiers



Alternative Format: Original Text Document



RFC 2074               RMON Protocol Identifiers            January 1997


1.  Introduction

   This memo defines an experimental portion of the Management
   Information Base (MIB) for use with network management protocols in
   the Internet community.  In particular, it describes the algorithms
   required to identify different protocol encapsulations managed with
   the Remote Network Monitoring MIB Version 2 [RMON2]. Although related
   to the original Remote Network Monitoring MIB [RFC 1757], this
   document refers only to objects found in the RMON-2 MIB.

2.  The SNMP Network Management Framework

   The SNMP Network Management Framework presently consists of three
   major components.  They are:

o    the SMI, described in RFC 1902 [RFC 1902], - the mechanisms used for
     describing and naming objects for the purpose of management.

o    the MIB-II, STD 17, RFC 1213 [RFC 1213], - the core set of managed
     objects for the Internet suite of protocols.

o    the protocol, STD 15, RFC 1157 [RFC 1157] and/or RFC 1905 [RFC 1905],
     - the protocol for accessing managed information.

   Textual conventions are defined in RFC 1903 [RFC 1903], and
   conformance statements are defined in RFC 1904 [RFC 1904].

   The Framework permits new objects to be defined for the purpose of
   experimentation and evaluation.

2.1.  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.

3.  Overview

   The RMON-2 MIB [RMON2] uses hierarchically formatted OCTET STRINGs to
   globally identify individual protocol encapsulations in the
   protocolDirTable.
