Internet-Draft           Event Notification MIB             January 2005

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.

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 extend the Baseline Privacy Interface with the
   addition of CM authentication over the HFC network in DOCSIS1.1/2.0
   system 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

Internet-Draft           Event Notification MIB             January 2005

   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.

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

Internet-Draft           Event Notification MIB             January 2005

   the third field contains the element's value.

2.13  Upstream

   The direction from the CM to the CMTS.

3.  Overview

   High Speed Internet Service offering in 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 a challenge to properly
   manage 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.

   Unfortunately, only a minimal set of SNMP Notifications is currently
   available.  This notification MIB in conjunction with [11] and [12]
   provide a minimum set of standard DOCSIS Notifications that DOCSIS
   devices SHOULD support to enable successful management of DOCSIS
   devices and network.

   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].

   The Appendix H of [11] defines all DOCSIS 1.1 required events and the
   Appendix D of [12] does that for DOCSIS 2.0.  The notifications
   specified in this document are used to notify these events via SNMP.

   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 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.

Internet-Draft           Event Notification MIB             January 2005

   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].

5.  Contributors

   Thanks goes to the following people who have made significant
   contributions to this document: Junming Gao, Jean-Francois Mule, Dave
   Raftus, Pak Siripunkaw, and Rich Woundy.

6.  Acknowledgments

   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 Consideration

   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 while one intended 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 included in the notification message
   include: 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.

Ahmad & Nakanishi        Expires July 12, 2005                 [Page 37]
Internet-Draft           Event Notification MIB             January 2005

   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
   ----------        -----------------------
   docsDevNotifMIB   { mib-2 xxx }

   -- Editor's Note (to be removed prior to publication):  the IANA is
   requested to assign a value for "xxx" under the 'mib-2' sub-tree and
   to record the assignment in the SMI Numbers registry.  When the
   assignment has been made, the RFC Editor is asked to replace "xxx"
   (here and in the MIB module) with the assigned value and to remove
   this note.
