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.  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 process.

2.1.  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.

2.2.  Channel

   A specific frequency allocation with an RF medium, specified by
   channel width in Hertz (cycles per second) and by center frequency.
   Within the US Cable Systems, upstream channels are generally
   allocated from the 5-42MHz range while down stream channels are
   generally allocated from the 50-750MHz range depending on the
   capabilities of the given system.  The typical broadcast channel
   width in the US is 6MHz.  Upstream channel widths for DOCSIS vary.

   For European cable systems, upstream channels vary by country. The
   upper edge of upstream channel allocations vary between 25 MHz to 65
   MHz, and the lower edge of downstream channel allocations vary
   between 47 MHz and 87.5 MHz. The typical broadcast channel width in
   Europe is 8MHz. The actual parameters are of concern to systems
   deploying EuroDOCSIS technology.

2.3.  CM   Cable Modem.

   A CM acts as a "slave" station in a DOCSIS compliant cable data
   system.

2.4.  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.

2.5.  Codeword

   A characteristic of the Forward Error Correction scheme used
   above the RF media layer.

   See "Data-Over-Cable Service Interface Specifications: Radio
   Frequency Interface Specification SP-RFIv2.0-IO2-020617"

2.6.  Data Packet

   The payload portion of the MAC Packet.

2.7.  dBmV

   A measure of RF signal voltage amplitude, whose power level is
   determined by the characteristic impedance. A zero dB signal power
   is equivalent to 48.75 dBmV signal amplitude in a 75 Ohm system.

2.8.  DOCSIS

   "Data Over Cable Service Interface Specification".  A term
   referring to the ITU-T J.112 Annex B standard for cable modem
   systems [7].

2.9.  Downstream

   The direction from the head-end towards the subscriber.

2.10.  Head-end

   The origination point in most cable systems of the subscriber video
   signals.

2.11.  MAC Packet

   A DOCSIS PDU.

2.12.  MCNS

   "Multimedia Cable Network System".  Generally replaced in usage by
   DOCSIS.

2.13.  Mini-slot

   In general, an interval of time which is allocated by the
   CMTS to a given CM for that CM to transmit in an upstream direction.
   See "Data-Over-Cable Service Interface Specifications: Radio
   Frequency Interface Specification SP-RFIv2.0-IO2-020617",

2.14.  QPSK   Quadrature Phase Shift Keying.

   A particular modulation scheme on an RF medium. See [6].

2.15.  QAM   Quadrature Amplitude Modulation.

   A particular modulation scheme on RF medium.  Usually expressed
   with a number indicating the size of the modulation constellation
   (e.g. 16 QAM). See [6], or any other book on digital communications
   over RF for a complete explanation of this.

2.16.  RF

   Radio Frequency.

2.17.  Symbol-times

   A characteristic of the RF modulation scheme.
   See "Data-Over-Cable Service Interface Specifications: Radio
   Frequency Interface Specification SP-RFIv2.0-IO2-020617"

2.18.  Upstream

   The direction from the subscriber towards the head-end.


3.  Overview

   This MIB provides a set of objects required for the management of
   MCNS/DOCSIS compliant Cable Modem (CM) and Cable Modem Termination
   System (CMTS) RF interfaces.  The specification is derived in part
   from the parameters and protocols described in "Data-Over-Cable
   Service Interface Specifications: Radio Frequency Interface
   Specification SP-RFIv2.0-IO2-020617".

3.1.  Structure of the MIB

   This MIB is structured as three groups:

   o    Management information pertinent to both Cable Modems (CM) and
        Cable Modem Termination Systems (CMTS) (docsIfBaseObjects).

   o    Management information pertinent to Cable Modems only
        (docsIfCmObjects).

   o    Management information pertinent to Cable Modem Termination
        Systems only (docsIfCmtsObjects).

   Tables within each of these groups group objects functionally - e.g.
   Quality of Service, Channel characteristics, MAC layer management,
   etc.  Rows created automatically (e.g. by the device according to
   the hardware configuration) may and generally will have a mixture of
   configuration and status objects within them.  Rows that are meant
   to be created by the management station are generally restricted to
   configuration (read-create) objects.

3.1.1.  docsIfBaseObjects

   docsIfDownstreamChannelTable - This table describes the active
   downstream channels for a CMTS and the received downstream channel
   for a CM.

   docsIfUpstreamChannelTable - This table describes the active
   upstream channels for a CMTS and the current upstream transmission
   channel for a CM.

   docsIfQosProfileTable - This table describes the valid Quality of
   Service profiles for the cable data system.

   docsIfSignalQualityTable - This table is used to monitor RF signal
   quality characteristics of received signals.

   docsIfDocsisBaseCapability  - This object is used to indicate the
   highest level of DOCSIS version a cable device can support.

3.1.2.  docsIfCmObjects

   docsIfCmMacTable - This table is used to monitor the DOCSIS MAC
   interface and can be considered an extension to the ifEntry.

   docsIfCmStatusTable - This table maintains a number of status
   objects and counters for cable modems. There is a comparable table
   at the CMTS, docsIfCmtsCmStatusTable, which maintains similar
   counters from the CMTS point of view.

   docsIfCmServiceTable - This table describes the upstream service
   queues available at this CM.  There is a comparable table at the
   CMTS, docsIfCmtsServiceEntry, which describes the service queues
   from the point of view of the CMTS.

3.1.3.  docsIfCmtsObjects

   docsIfCmtsMacTable - Describes the attributes of each CMTS MAC
   interface.

   docsIfCmtsStatusTable - This table provides a set of aggregated
   counters which roll-up values and events that occur on the
   underlying sub-interfaces.

   docsIfCmtsCmStatusTable - This table is used to hold information
   about known (i.e. ranging, registered, and/or previously online)
   cable modems on the system serviced by this CMTS.

   docsIfCmtsServiceTable - This table provides access to the
   information related to upstream service queues.

   docsIfCmtsModulationTable - This table allows control over the
   modulation profiles for RF channels associated with this CMTS.

   docsIfCmtsMacToCmTable - This table allows fast access into the
   docsIfCmtsCmTable via a MAC address (of the CM) interface.

   docsIfCmtsChannelUtilizationTable - This table provides statistical
   load usage data for attached upstream and downstream physical
   channels.

   docsIfCmtsDownChannelCounterTable - This table provides statistical
   data for attached downstream channels, appropriate as input for load
   usage calculations.

   docsIfCmtsUpChannelCounterTable - This table provides statistical
   data for attached upstream channels, appropriate as input for load
   usage calculations.


3.2.  Relationship to the Interfaces MIB

   This section clarifies the relationship of this MIB to the
   Interfaces MIB [RFC2863]. Several areas of correlation are addressed
   in the following subsections.  The implementer is referred to the
   Interfaces MIB document in order to understand the general intent of
   these areas.

3.2.1.  Layering Model

   An instance of ifEntry exists for each RF Downstream interface, for
   each RF Upstream interface, for each Upstream logical Channel and
   for each RF MAC layer.
   The ifStackTable [RFC2863] MUST be implemented to identify
   relationships among sub-interfaces.

   The following example illustrates a CMTS MAC interface with one
   downstream and two upstream interfaces.

                              | <== to network layer
        +------------------ --+-------------------------------+
        |                     RF MAC                          |
        +--+------------------+------------------------+------+
           |                  |                        |
   +-------+-----+     +------+------+          +------+------+
   | Downstream1 |     |  Upstream1  |          |  Upstream2  |
   |             |     |             |          |             |
   +-------------+     ++-----------++          ++-----------++
                        |           |            |           |
                   +----+----+ +----+----+  +----+----+ +----+----+
                   |  Ch-1   | |  Ch-2   |  |  Ch-1   | |  Ch-2   |
                   |(A/TDMA) | |(S-CDMA) |  |(A/TDMA) | |(S-CDMA) |
                   +---------+ +---------+  +---------+ +---------+


   As can be seen from this example, the RF MAC interface is layered on
   top of the downstream and upstream interfaces, and the RF Upstream
   interface is layered on top of an Upstream Logical Channels.

   In this example, the assignment of index values could be as follows:

   ifIndex       ifType                     Description

      2    docsCableMaclayer(127)           CATV MAC Layer
      3    docsCableDownstream(128)         CATV Downstream interface
      4    docsCableUpstream(129)           CATV Upstream interface
      5    docsCableUpstream(129)           CATV Upstream interface
      6    docsCableUpstreamChannel(205)    CATV Upstream Channel
      7    docsCableUpstreamChannel(205)    CATV Upstream Channel
      8    docsCableUpstreamChannel(205)    CATV Upstream Channel
      9    docsCableUpstreamChannel(205)    CATV Upstream Channel


      The corresponding ifStack entries would then be:

           | IfStackHigherLayer | ifStackLowerLayer |
           |         0          |         2         |
           |         2          |         3         |
           |         2          |         4         |
           |         2          |         5         |
           |         4          |         6         |
           |         4          |         7         |
           |         5          |         8         |
           |         5          |         9         |
           |         3          |         0         |
           |         6          |         0         |
           |         7          |         0         |
           |         8          |         0         |
           |         9          |         0         |

   The same interface model can also be used in Telephony or Telco
   Return systems.  A pure Telco Return system (Cable Modem as well as
   Cable Modem Termination System) would not have upstream, but only
   downstream cable channels.  Systems supporting both Telco Return and
   cable upstream channels can use the above model without
   modification.

   Telco Return Upstream channel(s) are handled by the appropriate
   MIBs, such as PPP or Modem MIBs.

3.2.2.  Virtual Circuits

   This medium does not support virtual circuits and this area is not
   applicable to this MIB.

3.2.3.  ifTestTable

   The ifTestTable is optional for Docsis CM/CMTS implementations, but
   is not specifically influenced by the RF mib.

3.2.4.  ifRcvAddressTable

   The ifRcvAddressTable is optional for Docsis CM/CMTS
   implementations, but is not specifically influenced by the RF mib.

3.2.5.  ifEntry

   This section documents only the differences from the requirements
   specified in the Interfaces MIB.  See that MIB for columns omitted
   from the descriptions below.

3.2.5.1.  ifEntry for Downstream interfaces

   The ifEntry for Downstream interfaces supports the
   ifGeneralInformationGroup and the ifPacketGroup of the Interfaces
   MIB.  This is an output only interface at the CMTS and all input
   status counters - ifIn* - will return zero.  This is an input only
   interface at the CM and all output status counters - ifOut* - will
   return zero.

             purpose of adjusting the SCDMA channel parameters of an
             active upstream row.
             The recommended procedure is:
             1) Create an inactive row through an SNMP SET using
                createAndWait(5). Use an ifIndex value outside the
                operational range of the system.
             2) Set the docsIfUpChannelCloneFrom field to the ifIndex
                value of the active row whose SCDMA parameters require
                adjustment.
             3) Adjust the SCDMA parameter values using the new
                temporary inactive row.
             4) Update the active row by setting object
                docsIfUpChannelUpdate to TRUE. This SET will fail if
                the adjusted SCDMA parameters are not compatible with
                each other.
             5) Delete the temporary row through an SNMP SET using
                DELETE.

             The following restrictions apply to this object:
             1) This object must contain a value of active(1) for
                active rows.
             2) Temporary inactive rows must be created using
                createAndWait(5).
             3) The only possible status change of a row created using
                createAndWait(5) (ie notInService(2)) is to destroy(6).
                These temporary rows must never become active.
             4) A status transition from active (1) to destroy (6) is
                not permitted. Entries with docsIfUpChannelStatus set
                to active(1) are logically linked to a physical
                interface, not temporarily created to clone parameters.
                The Interface MIB [RFC2863] ifAdminStatus should be
                used to take an Upstream Channel offline.

             physical upstream or downstream channel, accurate as of
             the most recent docsIfCmtsChannelUtilizationInterval.

             Upstream Channel Utilization Index:
             The upstream channel utilization index is expressed as a
             percentage of minislots utilized on the physical channel,
             regardless of burst type. For an Initial Maintenance
             region, the minislots for the complete region are
             considered utilized if the CMTS received an upstream
             burst within the region from any CM on the physical
             channel.  For contention REQ and REQ/DATA regions, the
             minislots for a transmission opportunity within the
             region are considered utilized if the CMTS received an
             upstream burst within the opportunity from any CM on the
             physical channel. For all other regions, utilized
             minislots are those in which the CMTS granted
             bandwidth to any unicast SID on the physical channel.

             For an upstream interface that has multiple logical
             upstream channels enabled, the utilization index is a
             weighted sum of utilization indices for the logical
             channels. The weight for each utilization index is the
             percentage of upstream minislots allocated for the
             corresponding logical channel.
             Example:
             If 75% of bandwidth is allocated to the first logical
             channel and 25% to the second, and the utilization
             indices for each are 60 and 40 respectively, the
             utilization index for the upstream physical channel is
             (60 * 0.75) + (40 * 0.25) = 55. This figure
             applies to the most recent utilization interval.

             Downstream Channel Utilization Index:
             The downstream channel utilization index is a percentage
             expressing the ratio between bytes used to transmit data
             versus the total number of bytes transmitted in the raw
             bandwidth of the MPEG channel. As with the upstream
             utilization index, the calculated value represents
             the most recent utilization interval.
             Formula:
             Downstream utilization index =
             (100 * (data bytes / raw bytes)) =
             (100 * ((raw bytes - stuffed bytes) / raw bytes))

             Definitions:
             Data bytes:    Number of bytes transmitted as data in the
                            docsIfCmtsChannelUtilizationInterval.

5.  Acknowledgments

    This document is a production of the Docsis 2.0 OSS Working Group.
    It is a revision based on RFC2670, "Radio Frequency (RF)
    Interface Management Information Base for DOCSIS compliant RF
    interfaces" [RFC2670].

    The current editor wishes to express gratitude to Rich Prodan, Aviv
    Goren, Greg Nakanishi, Rich Woundy, Eduardo Cardona, and Adi Shaliv
    for their valued advice and opinions.

    The current editor is also very grateful to colleague Andr‰ Lejeune
    for his timely and intelligent advice and assistance.


6.  Revision History

6.1. Scope

     This MIB in this document has been developed to accommodate
     DOCSIS 2.0 devices and their system capabilities. The MIB is an
     update to RFC2670 with the additional incorporation of EuroDocsis
     specific items and the DOCS_IF_EXT mib.

6.2. Extension

     We have maintained the MIB objects as defined in RFC 2670. In some
     cases new mib objects have been created with identical
     functionality but greater capacity (ie 32 to 64 bits). In these
     situations, both the original 32 bit objects and the new 64 bit
     objects must be implemented.

9.  Security Considerations

   This MIB relates to a system which will provide metropolitan public
   internet access.  As such, improper manipulation of the objects
   represented by this MIB may result in denial of service to a large
   number of end-users.  In addition, manipulation of the
   docsIfCmServiceQosProfile, docsIfCmtsServiceQosProfile, and the
   elements of docsIfQosProfileTable and docsIfCmtsModulationTable may
   allow an end-user to improve their service response or diminish
   other subscriber's service response.

   There are a number of management objects defined in this MIB that
   have a MAX-ACCESS clause of read-write or read-create.  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.

   SNMPv1 by itself is not a secure environment.  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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the
   use of the User-based Security Model RFC 2574 [12] and the View-
   based Access Control Model RFC 2575 [15] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, 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.


10.  Changes from RFC2670

   Upstream now separated into 'physical interfaces' and 'logical
   channels'. An instance of the docsIfUpstreamChannelTable exists
   for each 'logical channel'. The IANA ifType for 'logical channels'
   is 205. The IANA ifType for 'physical interfaces' remains at 129.

   Object docsIfDownChannelAnnex added to
   docsIfDownstreamChannelTable. This object originated in the
   EuroDocsis specifications.

   Nine new objects added to the docsIfUpstreamChannelTable. One
   describes the channel type in use. Four are specific S-CDMA
   parameters. Three are used in the creation of a temporary
   inactive upstream row so the S-CDMA parameters may be manipulated
   'offline'. One object has been added to enable/disable
   pre-equalization on the upstream channel.

   Object docsIfQosProfMaxTransmitBurst has been added to the
   docsIfQosProfileTable to replace deprecated object
   docsIfQosProfMaxTxBurst. This fixes a range error caused by switch
   to recording as bytes instead of minislots.

   Three new 64 bit counters added to the docsIfSignalQualityTable to
   extend the capacity of existing 32 bit counters.

   A new base object docsIfDocsisBaseCapability has been added which
   mirrors the functionality of the docsifExt mib object
   docsIfDocsisCapability, extended to include Docsis 2.0.

   Three new objects added to the docsIfCmStatusTable. One indicates
   the current modulation type. The second mirrors the functionality
   of the docsIfExt object docsIfDocsisOperMode, while clarifying that
   it applies to the COS/QOS mode used by the device. The third new
   object indicates equalization data at the CM.

   Two new 64 bit counters added to the docsIfCmServiceTable to extend
   the capacity of existing 32 bit counters.

   Seven new objects added to the docsIfCmtsCmStatusTable. Three are
   64 bit counters, two add ipv6 capability, and one indicates the CM
   modulation type in use. The remaining object mirrors the
   functionality of the docsIfExt object docsIfCmtsCmStatusDocsisMode,
   while clarifying that it applies to the COS/QOS mode used by the
   device.

   One object added to the docsIfCmtsServiceTable to fix a range error
   in an existing object, that has been deprecated.

   Eight new objects added to the docsIfCmtsModulationTable. Seven of
   these describe ATDMA/S-CDMA channel parameters, while the other
   describes modulation attributes common to all modulation types.

   One new object and three new tables added to provide CMTS upstream
   and downstream channel utilization data.

   Enumerated values for object docsIfDownChannelInterleave have been
   expanded to include a EuroDocsis value.

   Enumerated values for object docsIfCmtsModIntervalUsageCode have
   been expanded to include new Docsis 2.0 values.

   Enumerated values for object docsIfCmtsModType have been expanded
   to include new Docsis 2.0 values.

   Compliance statements have been updated to reflect new objects and
   to describe EuroDocsis specific implementation features.

   The descriptions of objects docsIfCmtsStatusInvalidRegReqs and
   docsIfCmtsStatusFailedRegReqs have been clarified.

   Separated references into normative and informative.


11.  Conflict Resolution with docsIfExt MIB

   The docsIfExt MIB originated as an engineering change notification
   (ECN) to the Docsis 1.1 specifications, and consisted of three
   objects - two for CM implementation and one for the CMTS. These
   three objects have been incorporated into this new version of the
   RF MIB, and have been assigned new object identifiers.

   The following process has been used to accomplish the deprecation
   of the docsIfExt MIB:

   1) Created Docsis ECNs (oss2-n-02016/oss-n-02017) that required
   Docsis 1.1/2.0 implementations to support the new location of the
   three docsIfExt objects in the RF MIB.

   2) The same ECNs updated the docsCableDeviceTrap MIB to reference
   the new location of the three docsIfExt objects, and deprecated
   the former references.

   3) The same ECNs deprecated the docsIfExt MIB.

   Following these steps, the state of affairs is:
   a) Docsis 1.1 MUST support new RF MIB docsIfExt objects.
   b) Docsis 1.1 MAY support remaining RF MIB 2.0 objects.
   c) Docsis 1.1 MAY support former docsIfExt MIB objects.
   d) Docsis 2.0 MUST support all new RF MIB objects.
   e) Docsis 2.0 MUST NOT support former docsIfExt MIB objects.
