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 Simple
Network Management Protocol (SNMP) based event notification
management of Data Over Cable Service Interface Specification
(DOCSIS) compliant Cable Modems and Cable Modem Termination Systems.
This MIB is defined as an extension to the DOCSIS Cable Device MIB.
This memo specifies a MIB module in a manner that is compliant to the
Structure of Management Information Version 2 (SMIv2). The set of
objects is consistent with the SNMP framework and existing SNMP
standards.

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 [16].
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 [2], STD 58, RFC 2579 [3] and STD 58, RFC 2580 [4].
2. Glossary
The terms in this document are derived either from normal cable
system usage, or from the documents associated with the Data Over
Cable Service Interface Specification (DOCSIS) process.
Ahmad & Makanishi Standards Track [Page 2]
RFC 4547 Event Notification MIB June 2006
2.1. BPI - Baseline Privacy Interface
A mechanism for providing data privacy over the HFC network in DOCSIS
1.0 systems [8].
2.2. BPI - Baseline Privacy Plus Interface
A mechanism that extends the Baseline Privacy Interface with the
addition of CM authentication over the HFC network in DOCSIS 1.1/2.0
systems and beyond [9].
2.3. CATV
Originally "Community Antenna Television", now used to refer to any
cable or hybrid fiber and cable system used to deliver video signals
to a community.
2.4. CM - Cable Modem
A CM acts as a "slave" station in a DOCSIS-compliant cable data
system.
2.5. CMTS - Cable Modem Termination System
A generic term covering a cable bridge or cable router in a head-end.
A CMTS acts as the master station in a DOCSIS-compliant cable data
system. It is the only station that transmits downstream, and it
controls the scheduling of upstream transmissions by its associated
CMs.
2.6. DOCSIS
DOCSIS stands for "Data-over-Cable Service Interface Specifications"
and refers to the ITU-T J.112 Annex B standard for cable modem
systems [10], [13] commonly known as DOCSIS 1.0. The DOCSIS 1.1
specification is an extension of DOCSIS 1.0, with new features to
support quality of service, fragmentation, and requirements for
European cable plants [14].
DOCSIS 2.0 [15] builds upon DOCSIS 1.1 and provides all of the
features and functionality that DOCSIS 1.1 provides. In addition, it
provides some significant enhancements in upstream capacity over
DOCSIS 1.1, such as 30.72 Mbps maximum upstream channel capacity,
Synchronous-Code Division Multiple Access (CDMA) operation, increased
robustness to upstream noise and channel impairments, Enhanced Reed-
Solomon error correction, and Trellis Coded Modulation.
Ahmad & Makanishi Standards Track [Page 3]
RFC 4547 Event Notification MIB June 2006
2.7. Downstream
The direction from the CMTS to the CM.
2.8. Head-end
The origination point in most cable systems of the subscriber video
signals. Generally also the location of the CMTS equipment.
2.9. MAC Packet
A term referring to DOCSIS Protocol Data Unit (PDU).
2.10. RF
A term referring to Radio Frequency.
2.11. SID
A term referring to DOCSIS Service ID. The SID identifies a
particular upstream bandwidth allocation and class-of-service
management for DOCSIS, and identifies a particular bidirectional
security association for BPI.
2.12. TLV
TLV stands for Type/Length/Value. TLV is an encoding method
consisting of three fields. The first field indicates the type of
element, the second field indicates the length of the element, and
the third field contains the element's value.
2.13. Upstream
The direction from the CM to the CMTS.
3. Overview
Offering High Speed Internet Service in the cable industry has become
extremely successful. DOCSIS devices are being deployed at a rate of
multiple thousands per day. Although operators are enjoying
successful deployment, they are also facing the challenge of properly
managing deployed devices. Operators are using Simple Network
Management Protocol, a set of Management Information Base (MIB)
required by DOCSIS, and SNMP Notifications to manage deployed DOCSIS
devices. The usage of SNMP Notification for event reporting is
becoming more popular as an effective and efficient method for
network monitoring.
Ahmad & Makanishi Standards Track [Page 4]
RFC 4547 Event Notification MIB June 2006
Unfortunately, only a minimal set of SNMP Notifications is currently
available. This notification MIB, in conjunction with [11] and [12],
provides a minimum set of standard DOCSIS Notifications that DOCSIS
devices SHOULD support to enable successful management of DOCSIS
devices and networks.
This document defines a set of objects required for the event
notification management of DOCSIS-compliant Cable Modems (CMs) and
Cable Modem Termination Systems (CMTSs). The MIB module is derived
from the DOCSIS [11] and [12].
Appendix H of [11] defines all DOCSIS 1.1 required events, and
Appendix D of [12] does that for DOCSIS 2.0. The notifications
specified in this document are used to notify these events via SNMP.
In this document, the key words "MUST", "MUST NOT", "REQUIRED",
"SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY",
and "OPTIONAL" are to be interpreted as described in RFC 2119 [1].
3.1. Structure of the MIB
This DOCS-IETF-CABLE-DEVICE-NOTIFICATION-MIB was designed to extend
the RFC2669 [5] notification module.
Two groups of SNMP notification objects are defined in this document.
One group defines notifications for cable modem events, and the other
group defines notifications for cable modem termination system
events.
DOCSIS defines numerous events, and each event is assigned to a
functional category. This MIB defines a notification object for each
functional category. The varbinding list of each notification
includes information about the event that occurred on the device.
4. Definitions
The MIB module defined here IMPORTs from SNMPv2-SMI [2], SNMPv2-CONF
[3], DOCS-CABLE-DEVICE-MIB [5], DOCS-IF-MIB [6], and IF-MIB [7].

6. Acknowledgements
This document was produced by the IPCDN Working Group. Thanks to
Harrie Hazewinkel and Bert Wijnen for their thorough review and
insightful comments on this document. Special thanks to Rich Woundy,
who made several valuable suggestions to improve the notifications.
7. Security Considerations
There are two management objects defined in this MIB module with a
MAX-ACCESS clause of read-write and/or read-create
(docsDevCmNotifControl and docsDevCmtsNotifControl). Such objects
may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations.
Setting docsDevCmNotifControl or docsDevCmtsNotifControl may cause
flooding of notifications, which can disrupt network service.
Besides causing "flooding", changing the objects can also mean that
notifications will not be emitted when one intends that to happen.
This MIB defines a number of notification objects that send detailed
information about the event that caused the generation of the
notification. Information in the notification message includes:
event priority, the event Id, the event message body, the CM DOCSIS
capability, the CM DOCSIS QOS level, the CM DOCSIS upstream
modulation type, the cable interface MAC address of the cable modem,
and the cable card MAC address of the CMTS to which the modem is
connected. The monitoring of these notification messages could be
used to gather information about the state of the network and devices
(CM and CMTS) attached to the network.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [16], section 8), including
full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an

instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
8. IANA Considerations
The MIB module defined in this document uses the following IANA-
assigned OBJECT IDENTIFIER values recorded in the SMI Numbers
registry:
Descriptor OBJECT IDENTIFIER value
