Category: Standards Track
Management Information Base for
Data Over Cable Service Interface Specification (DOCSIS)
Cable Modem Termination Systems for Subscriber Management
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 the Internet community.
In particular, it defines a set of managed objects for Simple Network
Management Protocol (SNMP)-based management of Data-over-Cable
Service Interface Specification (DOCSIS)-compliant Cable Modem
Termination Systems. These managed objects facilitate protection of
the cable network from misuse by subscribers. The Differentiated
Services MIB (RFC 3289) provides the filtering functions needed here,
making use of classification items defined in this specification.

1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
2. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14, RFC 2119
[RFC2119].
3. Overview
This MIB module provides a set of objects required for the management
of DOCSIS Cable Modem Termination Systems (CMTS). The specification
is derived in part from the operational model described in the DOCSIS
Radio Frequency Interface Specification [ITU-T-J122]. These managed
objects facilitate protection of the cable network from misuse by
subscribers. This misuse might include, for example, address
spoofing, service spoofing, or operation of unauthorized services.
