Introduction 76 This memo defines a portion of the Management Information Base (MIB) 77 for use with network management protocols in the Internet community. 78 In particular, it defines objects for managing ethernet-like 79 interfaces. 81 This memo also includes a MIB module. This MIB module extends the 82 list of managed objects specified in the earlier version of this MIB: 83 RFC1650 [11]. 85 The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 86 "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this 87 document are to be interpreted as described in [13]. 89 2. The SNMP Network Management Framework 91 The SNMP Network Management Framework consists of several components. 92 For the purpose of this specification, the applicable components of 93 the Framework are the SMI and related documents [2, 3, 4], which 94 define the mechanisms used for describing and naming objects for the 95 purpose of management. 97 The Framework permits new objects to be defined for the purpose of 98 experimentation and evaluation. 100 2.1. Object Definitions 102 Managed objects are accessed via a virtual information store, termed 103 the Management Information Base or MIB. Objects in the MIB are 104 defined using the subset of Abstract Syntax Notation One (ASN.1) [1] 105 defined in the SMI [2]. In particular, each object object type is 106 named by an OBJECT IDENTIFIER, an administratively assigned name. 107 The object type together with an object instance serves to uniquely 108 identify a specific instantiation of the object. For human 109 convenience, we often use a textual string, termed the descriptor, to 110 refer to the object type. 112 3. Change Log 114 This section enumerates changes made to RFC 1650 to produce this 115 document. 117 (1) The MODULE-IDENTITY has been updated to reflect the changes 118 in the MIB. 120 (2) A new object, dot3StatsSymbolErrors, has been added. 122 (3) The definition of the object dot3StatsIndex has been 123 converted to use the SMIv2 OBJECT-TYPE macro. 125 (4) A new conformance group, etherStats100MbsGroup, has been 126 added. 128 (5) A new compliance statement, ether100MbsCompliance, has 129 been added. 131 (6) The Acknowledgements were extended to provide a more 132 complete history of the origin of this document. 134 (7) The discussion of ifType has been expanded. 136 (8) A section on mapping of Interfaces MIB objects has 137 been added. 139 (9) A section defining the relationship of this MIB to 140 the MAU MIB has been added. 142 (10) A section on the mapping of IEEE 802.3 managed objects 143 to this MIB and the Interfaces MIB has been added. 145 (11) Converted the dot3Tests, dot3Errors, and dot3ChipSets 146 OIDs to use the OBJECT-IDENTITY macro. 148 (12) Added to the The list of registered dot3ChipSets. 150 (13) An intellectual property notice and copyright notice 151 were added, as required by RFC 2026. 153 4. Overview 155 Instances of these object types represent attributes of an interface 156 to an ethernet-like communications medium. At present, ethernet-like 157 media are identified by the following values of the ifType object in 158 the Interfaces MIB [12]: 160 ethernetCsmacd(6) 161 iso88023Csmacd(7) 162 starLan(11) 164 The definitions presented here are based on the IEEE 802.3 Layer 165 Management Specification [5], as originally interpreted by Frank 166 Kastenholz then of Interlan in [7]. Implementors of these MIB 167 objects should note that the IEEE document explicitly describes (in 168 the form of Pascal pseudocode) when, where, and how various MAC 169 attributes are measured. The IEEE document also describes the 170 effects of MAC actions that may be invoked by manipulating instances 171 of the MIB objects defined here. 173 To the extent that some of the attributes defined in [5] are 174 represented by previously defined objects in the Internet-standard 175 MIB or in the Interfaces Group Evolution MIB [12], such attributes 176 are not redundantly represented by objects defined in this memo. 177 Among the attributes represented by objects defined in other memos 178 are the number of octets transmitted or received on a particular 179 interface, the number of frames transmitted or received on a 180 particular interface, the promiscuous status of an interface, the MAC 181 address of an interface, and multicast information associated with an 182 interface. 184 4.1. Relation to MIB-2 185 This section applies only when this MIB is used in conjunction with 186 the "old" (RFC 1213) interface group. 188 The relationship between an ethernet-like interface and an interface 189 in the context of the Internet-standard MIB is one-to-one. As such, 190 the value of an ifIndex object instance can be directly used to 191 identify corresponding instances of the objects defined herein. 193 For agents which implement the (now deprecated) ifSpecific object, an 194 instance of that object that is associated with an ethernet-like 195 interface has the OBJECT IDENTIFIER value: 197 dot3 OBJECT IDENTIFER ::= { transmission 7 } 199 4.2. Relation to the Interfaces MIB 201 The Interface MIB [12] requires that any MIB which is an adjunct of 202 the Interface MIB clarify specific areas within the Interface MIB. 203 These areas were intentionally left vague in the Interface MIB to 204 avoid over constraining the MIB, thereby precluding management of 205 certain media-types. 207 Section 3.3 of [12] enumerates several areas which a media-specific 208 MIB must clarify. Each of these areas is addressed in a following 209 subsection. The implementor is referred to [12] in order to 210 understand the general intent of these areas. 212 4.2.1. Layering Model 214 This MIB does not provide for layering. There are no sublayers. 216 EDITOR'S NOTE: 218 One could foresee the development of an 802.2 and enet-transceiver 219 MIB. They could be higher and lower sublayers, respectively. All 220 that THIS document should do is allude to the possibilities and urge 221 the implementor to be aware of the possibility and that they may have 222 requirements which supersede the requirements in this document. 224 4.2.2. Virtual Circuits 226 This medium does not support virtual circuits and this area is not 227 applicable to this MIB. 229 4.2.3. ifTestTable 231 This MIB defines two tests for media which are instrumented with this 232 MIB; TDR and Loopback. Implementation of these tests is not 233 required. Many common interface chips do not support one or both of 234 these tests. 236 These two tests are provided as a convenience, allowing a common 237 method to invoke the test. 239 Standard MIBs do not include objects in which to return the results 240 of the TDR test. Any needed objects MUST be provided in the vendor 241 specific MIB. 243 Note that the ifTestTable is now deprecated. Work is underway to 244 define a replacement MIB for system and interface testing. It is 245 expected that the tests defined in this document will be usable in 246 this replacement MIB. 248 4.2.4. ifRcvAddressTable 250 This table contains all IEEE 802.3 addresses, unicast, multicast, and 251 broadcast, for which this interface will receive packets and forward 252 them up to a higher layer entity for local consumption. The format 253 of the address, contained in ifRcvAddressAddress, is the same as for 254 ifPhysAddress. 256 In the event that the interface is part of a MAC bridge, this table 257 does not include unicast addresses which are accepted for possible 258 forwarding out some other port. This table is explicitly not 259 intended to provide a bridge address filtering mechanism. 261 4.2.5. ifPhysAddress 263 This object contains the IEEE 802.3 address which is placed in the 264 source-address field of any Ethernet, Starlan, or IEEE 802.3 frames 265 that originate at this interface. Usually this will be kept in ROM 266 on the interface hardware. Some systems may set this address via 267 software. 269 In a system where there are several such addresses the designer has a 270 tougher choice. The address chosen should be the one most likely to 271 be of use to network management (e.g. the address placed in ARP 272 responses for systems which are primarily IP systems). 274 If the designer truly can not chose, use of the factory- provided ROM 275 address is suggested. 277 If the address can not be determined, an octet string of zero length 278 should be returned. 280 The address is stored in binary in this object. The address is 281 stored in "canonical" bit order, that is, the Group Bit is positioned 282 as the low-order bit of the first octet. Thus, the first byte of a 283 multicast address would have the bit 0x01 set. 285 4.2.6. ifType 287 This MIB applies to interfaces which have any of the following ifType 288 values: 290 ethernetCsmacd(6) 291 iso88023Csmacd(7) 292 starLan(11) 294 It is RECOMMENDED that all Ethernet-like interfaces use an ifType of 295 ethernetCsmacd(6) regardless of the speed that the interface is 296 running or the link-layer encapsulation in use. iso88023Csmacd(7) 297 and starLan(11) are supported for backwards compatability. 299 There are two other interface types defined in the IANAifType-MIB for 300 100 Mbit Ethernet. They are fastEther(62), and fastEtherFX(69). 301 This document takes the position that an Ethernet is an Ethernet, and 302 Ethernet interfaces SHOULD always have the same value of ifType. 303 Information on the particular flavor of Ethernet that an interface is 304 running is available from ifSpeed in the Interfaces MIB, and 305 ifMauType in the 802.3 MAU MIB. An Ethernet-like interface SHOULD 306 NOT use the fastEther(62) or fastEtherFX(69) ifTypes. 308 Interfaces with any of the supported ifType values map to the 309 EtherLike-MIB in the same manner. Which compliance statement an 310 interface should implement is dependent on the maximum speed 311 supported on the interface. The EtherLike-MIB etherCompliance 312 compliance statement applies to all Ethernet-like interfaces whose 313 maximum supported speed is 10 Mbit/sec or less. There are no 314 implementation differences. Similarly, the EtherLike-MIB 315 ether100MbsCompliance compliance statement applies to all Ethernet- 316 like interfaces whose maximum supported speed is 100Mbit/sec. 318 An interface that is capable of operating at 100Mbit/sec MUST 319 implement the ether100MbsCompliance compliance statement, even if it 320 is currently operating at a lower speed. Counters in the 321 ether100MbsCompliance compliance statement that only apply to 100 322 Mbit interfaces would simply not increment when the interface is 323 operating at a lower speed. 325 4.2.7. Specific Interface MIB Objects 327 The following table provides specific implementation guidelines for 328 applying the interface group objects to ethernet-like media. 330 Object 332 ifIndex Each ethernet-like interface is 333 represented by an ifEntry. The 334 dot3StatsTable in this MIB module is 335 indexed by dot3StatsIndex. The interface 336 identified by a particular value of 337 dot3StatsIndex is the same interface as 338 identified by the same value of ifIndex. 340 ifDescr Refer to [12]. 342 ifType Refer to section 4.2.6. 344 ifMtu 1500 octets. 346 ifSpeed The current operational speed of the 347 interface in bits per second. For 348 current ethernet-like interfaces, this 349 will be equal to 1,000,000 (1 million), 350 10,000,000 (10 million), or 100,000,000 351 (100 million). If the interface 352 implements auto-negotiation, 353 auto-negotiation is enabled for this 354 interface, and the interface has not yet 355 negotiated to an operational speed, this 356 object SHOULD reflect the maximum speed 357 supported by the interface. Note that 358 this object MUST NOT indicate a doubled 359 value when operating in full-duplex 360 mode. It MUST indicate the correct 361 line speed regardless of the current 362 duplex mode. The correct object to use 363 to determine the duplex mode of the 364 interface is the ifMauType object in the 365 802.3 MAU MIB. 367 ifPhysAddress Refer to section 4.2.5. 369 ifAdminStatus Write access is not required. Support 370 for 'testing' is not required. 372 ifOperStatus The operational state of the interface. 373 Support for 'testing' is not required. 374 The value 'dormant' has no meaning for 375 an ethernet-like interface. 377 ifLastChange Refer to [12]. 379 ifInOctets The number of octets in valid MAC frames 380 received on this interface, including 381 the MAC header and FCS. 383 ifInUcastPkts Refer to [12]. 385 ifInDiscards Refer to [12]. 387 ifInErrors The sum for this interface of 388 dot3StatsAlignmentErrors, 389 dot3StatsFCSErrors, 390 dot3StatsFrameTooLongs, 391 dot3StatsInternalMacReceiveErrors and 392 dot3StatsSymbolErrors. 394 ifInUnknownProtos Refer to [12]. 396 ifOutOctets The number of octets transmitted in 397 valid MAC frames on this interface, 398 including the MAC header and FCS. 400 ifOutUcastPkts Refer to [12]. 402 ifOutDiscards Refer to [12]. 404 ifOutErrors The sum for this interface of: 405 dot3StatsSQETestErrors, 406 dot3StatsLateCollisions, 407 dot3StatsExcessiveCollisions, 408 dot3StatsInternalMacTransmitErrors and 409 dot3StatsCarrierSenseErrors. 411 ifName Locally-significant textual name for the 412 interface (e.g. lan0). 414 ifInMulticastPkts Refer to [12]. 416 ifInBroadcastPkts Refer to [12]. 418 ifOutMulticastPkts Refer to [12]. 420 ifOutBroadcastPkts Refer to [12]. 422 ifHCInOctets 64-bit versions of counters. Required 423 ifHCOutOctets for ethernet-like interfaces that are 424 capable of operating at 20Mbit/sec or 425 faster, even if the interface is 426 currently operating at less than 427 20Mbit/sec. 429 ifHCInUcastPkts 64-bit versions of packet counters. 430 ifHCInMulticastPkts Support for these counters is not 431 ifHCInBroadcastPkts required for the interface types 432 ifHCOutUcastPkts supported by this MIB. They are only 433 ifHCOutMulticastPkts required for interfaces capable of 434 ifHCOutBroadcastPkts operating at 640Mbit/sec or faster. 435 Note that a future revision of this 436 document may support faster interfaces, 437 and therefore may require support for 438 these counters. 440 ifLinkUpDownTrapEnable Refer to [12]. Default is 'enabled' 442 ifHighSpeed The current operational speed of the 443 interface in millions of bits per 444 second. For current ethernet-like 445 interfaces, this will be equal to 1, 10, 446 or 100. If the interface implements 447 auto-negotiation, auto-negotiation is 448 enabled for this interface, and the 449 interface has not yet negotiated to an 450 operational speed, this object SHOULD 451 reflect the maximum speed supported by 452 the interface. Note that this object 453 MUST NOT indicate a doubled value when 454 operating in full-duplex mode. It MUST 455 indicate the correct line speed 456 regardless of the current duplex mode. 457 The correct object to use to determine 458 the duplex mode of the interface is the 459 ifMauType object in the 802.3 MAU MIB. 461 ifPromiscuousMode Refer to [12]. 463 ifConnectorPresent This will normally be 'true'. 465 ifAlias Refer to [12]. 467 ifCounterDiscontinuityTime Refer to [12]. 469 ifStackHigherLayer Refer to section 4.2.1. 470 ifStackLowerLayer 471 ifStackStatus 473 ifRcvAddressAddress Refer to section 4.2.4. 474 ifRcvAddressStatus 475 ifRcvAddressType 477 4.3. Relation to the 802.3 MAU MIB 479 Support for the mauModIfCompl compliance statement of the MAU-MIB 480 [14] is REQUIRED for Ethernet-like interfaces. This MIB is needed in 481 order to allow applications to determine the current MAU type in use 482 by the interface. The MAU type indicates not only the media type in 483 use, but also indicates whether the interface is operating in half- 484 duplex or full-duplex mode. Implementing this MIB module without 485 implementing the MAU-MIB would leave applications with no standard 486 way to determine the duplex mode of the interface. 488 4.4.

Acknowledgements 1645 This document was produced by the 802.3 Hub MIB Working Group. 1647 This document is almost completely based on both the Standard 1648 Ethernet MIB, RFC 1623 [10], and the Proposed Standard Ethernet MIB 1649 using the SNMPv2 SMI, RFC 1650 [11], both of which were edited by 1650 Frank Kastenholz of FTP Software and produced by the Ethernet MIB 1651 Working Group. This document extends those documents by providing 1652 support for 100 Mb/sec ethernet interfaces as outlined in [6]. 1654 RFC 1623 and RFC 1650, in turn, are based on the Draft Standard 1655 Ethernet MIB, RFC 1398 [9], also edited by Frank Kastenholz and 1656 produced by the Ethernet MIB Working Group. 1658 RFC 1398, in turn, is based on the Proposed Standard Ethernet MIB, 1659 RFC 1284 [8], which was edited by John Cook of Chipcom and produced 1660 by the Transmission MIB Working Group. The Ethernet MIB Working 1661 Group gathered implementation experience of the variables specified 1662 in RFC 1284 and used that information to develop this revised MIB. 1664 RFC 1284, in turn, is based on a document written by Frank 1665 Kastenholz, then of Interlan, entitled IEEE 802.3 Layer Management 1666 Draft M compatible MIB for TCP/IP Networks [7]. This document has 1667 been modestly reworked, initially by the SNMP Working Group, and then 1668 by the Transmission Working Group, to reflect the current conventions 1669 for defining objects for MIB interfaces. James Davin, of the MIT 1670 Laboratory for Computer Science, and Keith McCloghrie of Hughes LAN 1671 Systems, contributed to later drafts of this memo. Marshall Rose of 1672 Performance Systems International, Inc. converted the document into 1673 its current concise format. Anil Rijsinghani of DEC contributed text 1674 that more adequately describes the TDR test. Thanks to Frank 1675 Kastenholz of Interlan and Louis Steinberg of IBM for their 1676 experimentation. 1678 8.

Security Considerations 1742 Certain management information defined in this MIB may be considered 1743 sensitive in some network environments. Therefore, authentication of 1744 received SNMP requests and controlled access to management 1745 information should be employed in such environments. The method for 1746 this authentication is a function of the SNMP Administrative 1747 Framework, and has not been expanded by this MIB. 1749 10.
