In particular, it defines objects for managing ethernet-like objects. This memo also includes a MIB module. This MIB module corrects minor errors in the earlier versions of this MIB:RFC 1623 [20], andRFC1398 [15].Kastenholz [Page 1]
RFC 1643 Ethernet-Like MIB July 19941. The SNMP Network Management Framework The SNMP Network Management Framework consists of three major components. They are: o STD 16/RFC 1155 [3] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. STD 16/RFC 1212 [13] defines a more concise description mechanism, which is wholly consistent with the SMI. oRFC 1156 [4] which defines MIB-I, the core set of managed objects for the Internet suite of protocols. STD 17/RFC 1213 [6] defines MIB-II, an evolution of MIB-I based on implementation experience and new operational requirements. o STD 15/RFC 1157 [5] which defines the SNMP, the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation.1.1. 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) [7] defined in the SMI [16]. In particular, each object 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.2. Change Log This section enumerates changes made toRFC 1398 to produce this document. (1) A section describing the applicability of various parts ofRFC 1573 to ethernet-like interfaces has been added. (2) A minor error in the description of the TDR test was fixed. (3) A loopback test was defined to replace the standard loopback test that was defined inRFC 1229.Kastenholz [Page 2]
RFC 1643 Ethernet-Like MIB July 1994 (4) The description of dot3CollFrequencies was made a bit clearer. (5) A new object, EtherChipset, has been added. This object replaces the ifExtnsChipSet object, which has been removed per the Interface MIB Evolution effort. (6) Several minor editorial changes, spelling corrections, grammar and punctuation corrections, and so forth, were made.3. Overview Instances of these object types represent attributes of an interface to an ethernet-like communications medium. At present, ethernet-like media are identified by three values of the ifType object in the Internet-standard MIB: ethernet-csmacd(6) iso88023-csmacd(7) starLan(11) For these interfaces, the value of the ifSpecific variable in the MIB-II [6] has the OBJECT IDENTIFIER value: dot3 OBJECT IDENTIFER ::= { transmission 7 } The definitions presented here are based on the IEEE 802.3 Layer Management Specification [9], as originally interpreted by Frank Kastenholz then of Interlan in [10]. Implementors of these MIB objects should note that the IEEE document explicitly describes (in the form of Pascal pseudocode) when, where, and how various MAC attributes are measured. The IEEE document also describes the effects of MAC actions that may be invoked by manipulating instances of the MIB objects defined here. To the extent that some of the attributes defined in [9] are represented by previously defined objects in the Internet-standard MIB or in the Generic Interface Extensions MIB [11], such attributes are not redundantly represented by objects defined in this memo. Among the attributes represented by objects defined in other memos are the number of octets transmitted or received on a particular interface, the number of frames transmitted or received on a particular interface, the promiscuous status of an interface, the MAC address of an interface, and multicast information associated with an interface.Kastenholz [Page 3]
RFC 1643 Ethernet-Like MIB July 19943.1. Relation toRFC 1213 This section applies only when this MIB is used in conjunction with the "old" (i.e., pre-RFC 1573) interface group. The relationship between an ethernet-like interface and an interface in the context of the Internet-standard MIB is one-to-one. As such, the value of an ifIndex object instance can be directly used to identify corresponding instances of the objects defined herein.3.2. Relation toRFC 1573RFC 1573, the Interface MIB Evolution, requires that any MIB which is an adjunct of the Interface MIB, clarify specific areas within the Interface MIB. These areas were intentionally left vague inRFC 1573 to avoid over constraining the MIB, thereby precluding management of certain media-types.Section 3.3 of RFC 1573 enumerates several areas which a media- specific MIB must clarify. Each of these areas is addressed in a following subsection. The implementor is referred toRFC 1573 in order to understand the general intent of these areas.3.2.1. Layering Model This MIB does not provide for layering. There are no sublayers. EDITOR'S NOTE: I could forsee the development of an 802.2 and enet-transceiver MIB. They could be higher and lower sublayers, respectively. All that THIS document should do is allude to the possibilities and urge the implementor to be aware of the possibility and that they may have requirements which supersede the requirements in this document.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 This MIB defines two tests for media which are instumented with this MIB; TDR and Loopback. Implementation of these tests is not required. Many common interface chips do not support one or both of these tests.Kastenholz [Page 4]
RFC 1643 Ethernet-Like MIB July 1994 These two tests are provided as a convenience, allowing a common method to invoke the test. Standard MIBs do not include objects in which to return the results of the TDR test. Any needed objects MUST be provided in the vendor specific MIB.3.2.4. ifRcvAddressTable This table contains all IEEE 802.3 addresses, unicast, multicast, and broadcast, for which this interface will receive packets and forward them up to a higher layer entity for local consumption. The format of the address, contained in ifRcvAddressAddress, is the same as for ifPhysAddress. In the event that the interface is part of a MAC bridge, this table does not include unicast addresses which are accepted for possible forwarding out some other port. This table is explicitly not intended to provide a bridge address filtering mechanism.3.2.5. ifPhysAddress This object contains the IEEE 802.3 address which is placed in the source-address field of any Ethernet, Starlan, or IEEE 802.3 frames that originate at this interface. Usually this will be kept in ROM on the interface hardware. Some systems may set this address via software. In a system where there are several such addresses the designer has a tougher choice. The address chosen should be the one most likely to be of use to network management (e.g. the address placed in ARP responses for systems which are primarily IP systems). If the designer truly can not chose, use of the factory- provided ROM address is suggested. If the address can not be determined, an octet string of zero length should be returned. The address is stored in binary in this object. The address is stored in "canonical" bit order, that is, the Group Bit is positioned as the low-order bit of the first octet. Thus, the first byte of a multicast address would have the bit 0x01 set.Kastenholz [Page 5]
RFC 1643 Ethernet-Like MIB July 19943.2.6. ifType This MIB applies to interfaces which have any of the following three ifType values: ethernet-csmacd(6) iso88023-csmacd(7) starLan(11) Interfaces with any of these ifType values map to the EtherLike-MIB in the same manner. The EtherLike-MIB applies equally to all three types; there are no implementation differences.4.

This document is based on the Proposed Standard Ethernet MIB,RFC1284 [14], of which Jihn Cook of Chipcom was the editor. The Ethernet MIB Working Group gathered implementation experience of the variables specified inRFC 1284 and used that information to develop this revised MIB.RFC 1284, in turn, is based on a document written by Frank KastenholzKastenholz [Page 16]
RFC 1643 Ethernet-Like MIB July 1994 of Interlan entitled IEEE 802.3 Layer Management Draft M compatible MIB for TCP/IP Networks [10]. This document has been modestly reworked, initially by the SNMP Working Group, and then by the Transmission Working Group, to reflect the current conventions for defining objects for MIB interfaces. James Davin, of the MIT Laboratory for Computer Science, and Keith McCloghrie of Hughes LAN Systems, contributed to later drafts of this memo. Marshall Rose of Performance Systems International, Inc. converted the document into its current concise format. Anil Rijsinghani of DEC contributed text that more adequately describes the TDR test.
