- 1. 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].
-
- 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
- MIB.

- 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 [16].
-
- 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 a CMTS and the current upstream transmission channel
- for a CM.
-
- docsIfQosProfileTable - This table describes the valid Quality of
- Service service profiles for the cable data system.
-
- docsIfSignalQualityTable - This table is used to monitor RF signal
- quality characteristics of received signals.
-
-
-
- St. Johns Standard [Page 6]
-
- RFC 2670 DOCSIS RF Interface MIB August 1999
-
-
- 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 (e.g. registered) 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 implementor 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, and for each RF MAC layer. The
- ifStackTable [17] MUST be implemented to identify relationships among
- sub-interfaces.
-
-
-
-
-
-
-
-
- St. Johns Standard [Page 7]
-
- RFC 2670 DOCSIS RF Interface MIB August 1999
-
-
- The following example illustrates a MAC interface with one downstream
- and two upstream channels.
-
- | <== to network layer
- +-------------+--------------+
- | RF MAC |
- +----+---------+-----------+-+
- | | |
- +---------+---+ +---+-------+ +-+---------+
- | Downstream1 | | Upstream1 | | Upstream2 |
- +-------------+ +-----------+ +-----------+
-
- As can be seen from this example, the RF MAC interface is layered on
- top of the downstream and upstream interfaces.
-
- In this example, the assignment of index values could be as follows:
-
- ifIndex ifType Description
-
- 1 docsCableMaclayer(127) CATV MAC Layer
- 2 docsCableDownstream(128) CATV Downstream interface
- 3 docsCableUpstream(129) CATV Upstream interface
- 4 docsCableUpstream(129) CATV Upstream interface
-
- The corresponding ifStack entries would then be:
-
- | IfStackHigherLayer | ifStackLowerLayer |
- | 0 | 1 |
- | 1 | 2 |
- | 1 | 3 |
- | 1 | 4 |
- | 2 | 0 |
- | 3 | 0 |
- | 4 | 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.
-
-
-
- St. Johns Standard [Page 8]
-
- RFC 2670 DOCSIS RF Interface MIB August 1999
-
-
- 3.2.3. ifTestTable
-
- The ifTestTable is not supported by this MIB.
-
- 3.2.4. ifRcvAddressTable
-
- The ifRcvAddressTable is not supported by this 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

- interface at the CM and all output status counters - ifOut* - will
- return zero.

- 5. Acknowledgments
-
- This document was produced by the IPCDN Working Group. It is based
- on a document written by Pam Anderson from CableLabs, Wilson Sawyer
- from BayNetworks, and Rich Woundy from Continental Cablevision. The
- original working group editor, Guenter Roeck of cisco Systems, did
- much of the grunt work of putting the document into its current form.
-
- Special thanks is also due to Azlina Palmer, who helped a lot
- reviewing the document.

- 7. 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 may allow an end-user to improve
- their service response or decrease other subscriber service response.

-
-
- This MIB does not affect confidentiality, authentication or
- authorization of services on a cable modem system. For
- authentication and authorization, please see the related document
- "Cable Device Management Information Base for DOCSIS compliant Cable
- Modems and Cable Modem Termination Systems" [18]. For
- confidentiality, the working group expects to issue a MIB which
- describes the management of the DOCSIS Baseline Privacy mechanism.
