The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [1]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The second version, called SMIv2, is described in STD 58, RFC 2578 [5], STD 58, RFC 2579 [6] and STD 58, RFC 2580 [7]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [8]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and RFC 2574 [12]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [8]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [13]. o A set of fundamental applications described in RFC 2573 [14] and the view-based access control mechanism described in RFC 2575 [15]. A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [21]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB MUST be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the Goren/Raftus Expires September 2002 [Page 3] Internet Draft DOCSIS RF Interface MIB April 2002 MIB. 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 See [25]. A characteristic of the Forward Error Correction scheme used above the RF media layer. 2.6. Data Packet Goren/Raftus Expires September 2002 [Page 4] Internet Draft DOCSIS RF Interface MIB April 2002 The payload portion of the MAC Packet. 2.7. dBmV Decibel relative to one milli-volt. A measure of RF power. 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 [20]. 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 See [25]. 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. 2.14. QPSK Quadrature Phase Shift Keying. A particular modulation scheme on an RF medium. See [19]. 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 [19], or any other book on digital communications over RF for a complete explanation of this. 2.16. RF Radio Frequency. 2.17. Symbol-times See [25]. A characteristic of the RF modulation scheme. Goren/Raftus Expires September 2002 [Page 5] Internet Draft DOCSIS RF Interface MIB April 2002 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 DOCSIS Radio Frequency Interface Specification [25]. 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. Goren/Raftus Expires September 2002 [Page 6] Internet Draft DOCSIS RF Interface MIB April 2002 3.1.2. docsIfCmObjects docsIfCmMacTable - This table is used to monitor the DOCSIS MAC interface and can be considered an extension to the ifEntry. 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 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. docsIfCmtsServiceEntry - 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. 3.2. Relationship to the Interfaces MIB This section clarifies the relationship of this MIB to the Interfaces MIB [17]. 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 [17] 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 | Goren/Raftus Expires September 2002 [Page 7] Internet Draft DOCSIS RF Interface MIB April 2002 +--+------------------+------------------------+------+ | | | +-------+-----+ +------+------+ +------+------+ | 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 Goren/Raftus Expires September 2002 [Page 8] Internet Draft DOCSIS RF Interface MIB April 2002 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.

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" [22]. The current editors wish to express gratitude to Rich Prodan, Greg Nakanishi, Rich Woundy, Eduardo Cardona, and Adi Shaliv for their valued advice and opinions. 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. 7. References [1] Harrington, D., Presuhn, R. and B.

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, docsIfCmtsServerQosProfile, 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 and/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 Goren/Raftus Expires September 2002 [Page 82] Internet Draft DOCSIS RF Interface MIB April 2002 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. 9. 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. Eight new objects added to the docsIfUpstreamChannelTable. One describes the channel type in use, while four are specific S-CDMA parameters. The remaining three additions are used in the creation of a temporary inactive upstream row so the S-CDMA parameters may be manipulated 'offline'. 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. A new base object docsIfDocsisBaseCapability has been added which mirrors the functionality of the docsifExt mib object docsIfDocsisCapability, extended to include Docsis 2.0. Two new objects added to the docsIfCmStatusTable. One indicates the current modulation type. The other mirrors the functionality of the docsIfExt object docsIfDocsisOperMode, while clarifying that it applies to the COS/QOS mode used by the device. 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. Goren/Raftus Expires September 2002 [Page 83] Internet Draft DOCSIS RF Interface MIB April 2002 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. 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. 10. 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. It is the intention of the authors to deprecate the docsIfExt MIB. Due to backward compatibility concerns with Docsis 1.1 implementations, both the new RF MIB objects and the former docsIfExt MIB objects will be required for Docsis 2.0 designs for the immediate future. An influencing factor in this decision is that the docsCableDeviceTrap MIB (from the same design update as the docsIfExt MIB) contains references to docsIfExt MIB objects in various trap definitions. The following process will be used to accomplish the eventual deprecation of the docsIfExt MIB: 1) Create a Docsis ECN that will require Docsis 1.1 implementations to support the new location of the three docsIfExt objects in the RF MIB. 2) The same ECN will update the docsCableDeviceTrap MIB to reference the new location of the three docsIfExt objects, and deprecate the former references. 3) The same ECN will deprecate the docsIfExt MIB. Following these steps, the state of affairs will be: 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 MAY support former docsIfExt MIB objects.
