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]. Raftus & Cardona Expires April 26, 2006 [Page 4] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 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. Baseline Privacy Security interface specification designed for DOCSIS compliant cable data systems that ensures device authentication data confidentiality in the CATV plant. See [BPI] and [BPIPLUS]. 2.2. 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. 2.3. 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 downstream 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 Euro-DOCSIS technology. The downstream channels conform to the requirements of ITU-T Recommendation J.83 [ITU-T_J.83] 2.4. CM or Cable Modem A CM acts as a "slave" station in a DOCSIS compliant cable data system. 2.5. CMTS or 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 Raftus & Cardona Expires April 26, 2006 [Page 5] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 controls the scheduling of upstream transmissions by its associated CMs. 2.6. 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-I09-050812" 2.7. Data Packet The payload portion of the MAC Packet. 2.8. 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. 2.9. DOCSIS "Data Over Cable Service Interface Specification". A term referring to the ITU-T J112 [ITU-T_J.112] Annex B standard for cable modem systems. 2.9.1. DOCSIS 1.0 Cable modem systems CM/CMTS compliant to requirements in [RFI1.0]. A common reference to DOCSIS 1.0 in this document is the upstream channel queuing mechanism known as Class of Service (COS). 2.9.2. DOCSIS 1.1 Cable modem systems CM/CMTS compliant to requirements in [ITU- T_J.112]. DOCSIS 1.1 references in this document are in part associated with the upstream and downstream Quality of Service (QOS). The term DOCSIS 1.x is used in this document to refer both DOCSIS 1.0 and DOCSIS 1.1. 2.9.3. DOCSIS 2.0 Cable modem systems CM/CMTS compliant to requirements in [ITU- T_J.122]. DOCSIS 2.0 corresponds to the second generation of radio- frequency interface specifications of DOCSIS. Raftus & Cardona Expires April 26, 2006 [Page 6] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 2.10. Downstream The direction from the head-end towards the subscriber. 2.11. Euro-DOCSIS Cable modem systems CM/CMTS conforming to the European spectrum lineup and compliant to requirements of Annex F in [ITU-T_J.122]. 2.12. Head-end The origination point in most cable systems of the subscriber video signals. Generally also the location of the CMTS equipment. 2.13. MAC Packet A DOCSIS PDU. 2.14. MCNS "Multimedia Cable Network System". Generally replaced in usage by DOCSIS. 2.15. 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 [ITU- T_J.122] 2.16. QPSK Quadrature Phase Shift Keying A particular modulation scheme on an RF medium. See [Proakis00]. 2.17. 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 [Proakis00]. 2.18. RF Radio Frequency. 2.19. Symbol-times A characteristic of the RF modulation scheme. See [ITU-T_J.122]. Raftus & Cardona Expires April 26, 2006 [Page 7] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 2.20. Upstream The direction from the subscriber towards the head-end. Raftus & Cardona Expires April 26, 2006 [Page 8] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 3. Overview This MIB module provides a set of objects required for the management of 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 [ITU-T_J.122]. 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 [RFC2119]. 3.1. Textual Conventions This MIB module define new textual conventions for CMs and CMTSs indication of DOCSIS 2.0 RFI capabilities, configuration, usage and backward compatible modes of operation defined in [RFI2.0] With the same purpose, there are some textual conventions that represent capabilities and modes of operation of [RFI1.1] that are not covered by RFC 2670, and are managed proprietarily in DOCSIS OSSI 1.1 specification [OSSI1.1]. 3.1.1. Textual Conventions in RFC 2670 RFC 2670 defined two textual conventions: TenthdBmV and TenthdB which are power measurement representations. 3.1.2. Textual Conventions in RFC XXXX Note to RFC editor: RFC editor to replace XXXX with this RFC number, then, delete note. This MIB module defines the textual convention DocsisUpstreamType to represent the DOCSIS 1.0 [RFI1.0] and DOCSIS 2.0 [RFI2.0] upstream burst modulation profiles types. This MIB module defines the textual conventions DocsisVersion and DocsisQosVersion to represent the DOCSIS 1.0 [RFI1.0] and DOCSIS 1.1 [RFI1.1] COS/QOS capabilities and modes of operation. 3.2. Structure of the MIB This MIB module is structured as three groups: o Management information pertinent to both Cable Modem (CM) and Cable Modem Termination System (CMTS) (docsIfBaseObjects). o Management information pertinent to Cable Modem only (docsIfCmObjects). Raftus & Cardona Expires April 26, 2006 [Page 9] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 o Management information pertinent to Cable Modem Termination System only (docsIfCmtsObjects). Tables within each of these groups cover diferent functions - e.g. upstream queue services, 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. 3.2.1. docsIfBaseObjects docsIfDownstreamChannelTable - This table describes the existing downstream channels for a CMTS and the received downstream channel for a CM. docsIfUpstreamChannelTable - This table describes the existing 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. 3.2.2. 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. 3.2.3. docsIfCmtsObjects docsIfCmtsMacTable - Describes the attributes of each CMTS MAC Raftus & Cardona Expires April 26, 2006 [Page 10] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 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. 3.2.4. Relationship to the Interfaces MIB module This section clarifies the relationship of this MIB module 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. 3.2.4.1. 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 the relationships among sub-interfaces. Raftus & Cardona Expires April 26, 2006 [Page 11] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 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) | +---------+ +---------+ +---------+ +---------+ Figure 1 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 channel. 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 Figure 2 The corresponding ifStack entries would then be: Raftus & Cardona Expires April 26, 2006 [Page 12] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 | 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) management is outside the scope of this document. 3.2.4.2. Virtual Circuits This medium does not support virtual circuits and this area is not applicable to this MIB module. 3.2.4.3. ifTestTable The ifTestTable is optional for DOCSIS CM/CMTS implementations, but is not specifically influenced by the RF MIB. 3.2.4.4. ifRcvAddressTable The ifRcvAddressTable is optional for DOCSIS CM/CMTS implementations, but is not specifically influenced by the RF MIB. 3.2.4.5. ifEntry This section documents only the differences from the requirements specified in the Interfaces MIB module.

Offline Upstream Parameters Handling 3.2.5.1. Overview This section describes the offline configuration of the DOCSIS 2.0 upstream logical interface parameters. The purpose of this feature is to guarantee that upstream logical interface parameters such as modulation profile, channel yype, mini-slot Size and SCDMA attributes are consistent prior to commit changes to an active upstream logical interface. This mechanism can reduce possible downtime of the upstream interface by minimizing SNMP SET operations to in-service upstream interfaces. This mechanism is supported by CMTSs and is not applicable to CMs. 3.2.5.2. Operation This mechanism uses three upstream channel MIB objects defined for DOCSIS 2.0 CMTS implementations: docsIfUpChannelStatus - The RowStatus object for the creation of temporary interfaces in the upstream interface table. A temporary entry is used to modify, validate and commit upstream parameters of a physical interface. In the CMTS, a physical upstream interfaces refers to an upstream logical channel interface. docsIfUpChannelCloneFrom - This MIB object has the function to associate a physical interface with a temporary interface for the purpose of updating the upstream parameters of the physical interface. docsIfUpChannelUpdate - This MIB object is the commit object that transfer the validated upstream parameters from the temporary interface to the physical interface. The offline upstream parameters handling operation is as follows: o A temporary interface is create with docsIfUpChannelStatus set to 'createAndWait', which turns the new create entry status to 'notReady'. Raftus & Cardona Expires April 26, 2006 [Page 25] Internet-Draft DOCSIS 2.0 Radio Frequency (RFI) MIB October 2005 o A SET to docsIfUpChannelCloneFrom in the temporary interface to the physical interface ifIndex value performs two actions: * Create the association of the physical interface to the temporary interface. * Copy the original upstream parameters from the physical interface to the temporary interface which turns its status to 'notInService'. o The operator modifies the temporary interface parameters to the desired values. o At this point, a SET to 'active' to the RowStatus of the temporary interface is successful if all parameters in the temporary interface are valid for the associated physical interface; otherwise, the temporary entry remains with status 'notInservice' and the SET returns error 'commitFailed'. o When the temporary interface status is 'active' a SET to docsIfUpChannelUpdate to 'true' transfer the temporary interface parameters values to the physical interface. o After completion of the update operations, the temporary interface is destroyed setting the docsIfUpChannelStatus to 'destroy'. 3.2.5.3. Relation of docsIfUpChannelStatus and ifMib The main purpose of docsIfUpChannelStatus is the creation of temporary interfaces for offline handling of the configuration of physical interfaces; It does not manage the creation or control of physical interfaces. To maintain a consistent operation and status report of interfaces, this object does not manage the administrative and operational status of physical interfaces.

Below is a mandatory procedure for adjusting the values of a physical interface : 1. Create a temporary interface entry through an SNMP SET using 'createAndWait'.

Set the docsIfUpChannelCloneFrom object to the ifIndex value of the physical row to update. Now docsIfUpChannelStatus reports 'notInService'. 3. Change the upstream parameters to the desired values into the temporary row. 4. Validate that all parameters are consistent by setting docsIfUpChannelStatus to 'active'.
