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 MCNS/DOCSIS compliant Radio Frequency (RF)
   interfaces.

   This memo specifies a MIB module in a manner that is compliant to the
   SNMP SMIv2 [5][6][7].  The set of objects are 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.
