Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a basic set of managed objects for SNMP-based management of MCNS compliant Radio Frequency (RF) interfaces. This memo specifies a MIB module in a manner that is compliant to the SNMPv2 SMI. The set of objects is consistent with the SNMP framework and existing SNMP standards. This memo does not specify a standard for the Internet community. This memo is a product of the IPCDN working group within the Internet Engineering Task Force. Comments are solicited and should be addressed to the working group's mailing list at ipcdn@terayon.com and/or the author.

The SNMPv2 Network Management Framework The SNMPv2 Network Management Framework presently consists of three major components. They are: o the SMI, described in RFC 1902 [1] - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects for the Internet suite of protocols. o the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for accessing managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 2. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to refer to the object type. Expires March 1998 [Page 3] INTERNET-DRAFT MCNS RF Interface MIB September 1997 3. Overview This MIB provides a set of objects required for the management of MCNS compliant Cable Modem (CM) and Cable Modem Termination System (CMTS) RF interfaces. The specification is derived from the MCNS Radio Frequency Interface specification [6]. 3.1. Structure of the MIB This MIB is structured in three groups: o Information required both in Cable Modems and Cable Modem Termination systems. o Information required in Cable Modems only. o Information required in Cable Modem Termination Systems only. 3.1.1. General Description 3.2. Relationship to the Interfaces MIB This section clarifies the relationship of this MIB to the Interfaces MIB [5]. 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 [5] must be implemented to identify relationships among sub-interfaces. 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. Expires March 1998 [Page 4] INTERNET-DRAFT MCNS RF Interface MIB September 1997 In this example, the assignment of index values could be as follows: ifIndex ifType Description 1 docsCableMaclayer(xx) CATV MAC Layer 2 docsCableDownstream(xx) CATV Downstream interface 3 docsCableUpstream(xx) CATV Upstream interface 4 docsCableUpstream(xx) 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 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. ifTestTable The ifTestTable is not supported by this MIB. 3.2.3. ifRcvAddressTable The ifRcvAddressTable is not supported by this MIB. 3.2.4. ifEntry 3.2.4.1. ifEntry for Downstream interfaces The ifEntry for Downstream interfaces supports the ifGeneralGroup and the ifPacketGroup of the Interfaces MIB. 3.2.4.1.1. ifEntry for Downstream interfaces in Cable Modem Termination Systems ifTable Comments ============== =========================================== ifIndex Each RF Cable Downstream interface is represented Expires March 1998 [Page 5] INTERNET-DRAFT MCNS RF Interface MIB September 1997 by an ifEntry. ifDescr Textual port description. ifType The IANA value of docsCableDownstream(xx). ifSpeed Return the speed of this downstream channel.
