Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in the Internet community.
   In particular, it defines a basic set of managed objects for SNMP-
   based management of DOCSIS 1.0 compliant Cable Modems and Cable Modem
   Termination Systems.

   This memo specifies a MIB module in a manner that is compliant to the
   SNMP SMIv2 [5][6][7].  The set of objects is consistent with the SNMP
   framework and existing SNMP standards.

   This memo is a product of the IPCDN working group within the Internet
   Engineering Task Force.  Comments are solicited and should be
   addressed to the working group's mailing list at ipcdn@terayon.com
   and/or the author.

1.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   o   An overall architecture, described in RFC 2571 [1].

   o   Mechanisms for describing and naming objects and events for the
       purpose of management. The first version of this Structure of
       Management Information (SMI) is called SMIv1 and described in STD
       16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4].  The
       second version, called SMIv2, is described in STD 58, RFC 2578
