Abstract
-
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. This memo obsoletes RFC 1650 "Definitions of Managed Objects for the Ethernet-like Interface Types using SMIv2". This memo extends that specification by including management information useful for the management of 100 Mb/s Ethernet interfaces.
Ethernet technology, as defined by the 802.3 Working Group of the IEEE, continues to evolve, with scalable increases in speed, new types of cabling and interfaces, and new features. This evolution may require changes in the managed objects in order to reflect this new functionality. This document, as with other documents issued by this working group, reflect a certain stage in the evolution of Ethernet technology. In the future, this document might be revised, or new documents might be issued by the Ethernet Interfaces and Hub MIB Working Group, in order to reflect the evolution of Ethernet technology.

1. Introduction
-
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for managing ethernet-like interfaces.
This memo also includes a MIB module. This MIB module extends the list of managed objects specified in the earlier version of this MIB: RFC1650 [11].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [13].
2. The SNMP Network Management Framework
-
The SNMP Network Management Framework consists of several components. For the purpose of this specification, the applicable components of the Framework are the SMI and related documents [2, 3, 4], which define the mechanisms used for describing and naming objects for the purpose of management.
The Framework permits new objects to be defined for the purpose of experimentation and evaluation.
2.1. 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) [1] defined in the SMI [2]. 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.
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 the following values of the ifType object in the Interfaces MIB [12]:
ethernetCsmacd(6)
iso88023Csmacd(7)
starLan(11)
-
The definitions presented here are based on the IEEE 802.3 Layer Management Specification [5], as originally interpreted by Frank Kastenholz then of Interlan in [7]. 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 [5] are represented by previously defined objects in MIB-2 [16] or in the Interfaces MIB [12], 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.
3.1. Relation to MIB-2
-
This section applies only when this MIB is used in conjunction with the "old" (RFC 1213) [16] 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.
For agents which implement the (now deprecated) ifSpecific object, an instance of that object that is associated with an ethernet-like interface has the OBJECT IDENTIFIER value:
dot3 OBJECT IDENTIFER ::= { transmission 7 }
3.2. Relation to the Interfaces MIB
-
The Interface MIB [12] 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 in the Interface MIB to avoid over constraining the MIB, thereby precluding management of certain media-types.
Section 3.3 of [12] enumerates several areas which a media-specific MIB must clarify. Each of these areas is addressed in a following subsection. The implementor is referred to [12] 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:
One could foresee 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 instrumented 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.
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.
Note that the ifTestTable is now deprecated. Work is underway to define a replacement MIB for system and interface testing. It is expected that the tests defined in this document will be usable in this replacement 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.
3.2.6. ifType
-
This MIB applies to interfaces which have any of the following ifType values:
ethernetCsmacd(6)
iso88023Csmacd(7)
starLan(11)
-
It is RECOMMENDED that all Ethernet-like interfaces use an ifType of ethernetCsmacd(6) regardless of the speed that the interface is running or the link-layer encapsulation in use. iso88023Csmacd(7) and starLan(11) are supported for backwards compatability.
There are two other interface types defined in the IANAifType-MIB for 100 Mbit Ethernet. They are fastEther(62), and fastEtherFX(69). This document takes the position that an Ethernet is an Ethernet, and Ethernet interfaces SHOULD always have the same value of ifType. Information on the particular flavor of Ethernet that an interface is running is available from ifSpeed in the Interfaces MIB, and ifMauType in the 802.3 MAU MIB. An Ethernet-like interface SHOULD NOT use the fastEther(62) or fastEtherFX(69) ifTypes.
Interfaces with any of the supported ifType values map to the EtherLike-MIB in the same manner. Which compliance statement an interface should implement is dependent on the maximum speed supported on the interface. The EtherLike-MIB etherCompliance compliance statement applies to all Ethernet-like interfaces whose maximum supported speed is 10 Mbit/sec or less. There are no implementation differences. Similarly, the EtherLike-MIB ether100MbsCompliance compliance statement applies to all Ethernet- like interfaces whose maximum supported speed is 100Mbit/sec.
An interface that is capable of operating at 100Mbit/sec MUST implement the ether100MbsCompliance compliance statement, even if it is currently operating at a lower speed. Counters in the ether100MbsCompliance compliance statement that only apply to 100 Mbit interfaces would simply not increment when the interface is operating at a lower speed.
3.2.7. Specific Interface MIB Objects
-
The following table provides specific implementation guidelines for applying the interface group objects to ethernet-like media.
Object ifIndex Each ethernet-like interface is represented by an ifEntry. The dot3StatsTable in this MIB module is indexed by dot3StatsIndex. The interface identified by a particular value of dot3StatsIndex is the same interface as identified by the same value of ifIndex. ifDescr Refer to [12]. ifType Refer to section 3.2.6. ifMtu 1500 octets. ifSpeed The current operational speed of the interface in bits per second. For current ethernet-like interfaces, this will be equal to 1,000,000 (1 million), 10,000,000 (10 million), or 100,000,000 (100 million). If the interface implements auto-negotiation, auto-negotiation is enabled for this interface, and the interface has not yet negotiated to an operational speed, this object SHOULD reflect the maximum speed supported by the interface. Note that this object MUST NOT indicate a doubled value when operating in full-duplex mode. It MUST indicate the correct line speed regardless of the current duplex mode. The correct object to use to determine the duplex mode of the interface is the ifMauType object in the 802.3 MAU MIB. ifPhysAddress Refer to section 3.2.5. ifAdminStatus Write access is not required. Support for 'testing' is not required. ifOperStatus The operational state of the interface. Support for 'testing' is not required. The value 'dormant' has no meaning for an ethernet-like interface. ifLastChange Refer to [12]. ifInOctets The number of octets in valid MAC frames received on this interface, including the MAC header and FCS. ifInUcastPkts Refer to [12]. ifInDiscards Refer to [12]. ifInErrors The sum for this interface of dot3StatsAlignmentErrors, dot3StatsFCSErrors, dot3StatsFrameTooLongs, dot3StatsInternalMacReceiveErrors and dot3StatsSymbolErrors. ifInUnknownProtos Refer to [12]. ifOutOctets The number of octets transmitted in valid MAC frames on this interface, including the MAC header and FCS. ifOutUcastPkts Refer to [12]. ifOutDiscards Refer to [12]. ifOutErrors The sum for this interface of: dot3StatsSQETestErrors, dot3StatsLateCollisions, dot3StatsExcessiveCollisions, dot3StatsInternalMacTransmitErrors and dot3StatsCarrierSenseErrors. ifName Locally-significant textual name for the interface (e.g. lan0). ifInMulticastPkts Refer to [12]. ifInBroadcastPkts Refer to [12]. ifOutMulticastPkts Refer to [12]. ifOutBroadcastPkts Refer to [12]. ifHCInOctets 64-bit versions of counters. Required ifHCOutOctets for ethernet-like interfaces that are capable of operating at 20Mbit/sec or faster, even if the interface is currently operating at less than 20Mbit/sec. ifHCInUcastPkts 64-bit versions of packet counters. ifHCInMulticastPkts Support for these counters is not ifHCInBroadcastPkts required for the interface types ifHCOutUcastPkts supported by this MIB. They are only ifHCOutMulticastPkts required for interfaces capable of ifHCOutBroadcastPkts operating at 640Mbit/sec or faster. Note that a future revision of this document may support faster interfaces, and therefore may require support for these counters. ifLinkUpDownTrapEnable Refer to [12]. Default is 'enabled' ifHighSpeed The current operational speed of the interface in millions of bits per second. For current ethernet-like interfaces, this will be equal to 1, 10, or 100. If the interface implements auto-negotiation, auto-negotiation is enabled for this interface, and the interface has not yet negotiated to an operational speed, this object SHOULD reflect the maximum speed supported by the interface. Note that this object MUST NOT indicate a doubled value when operating in full-duplex mode. It MUST indicate the correct line speed regardless of the current duplex mode. The correct object to use to determine the duplex mode of the interface is the ifMauType object in the 802.3 MAU MIB. ifPromiscuousMode Refer to [12]. ifConnectorPresent This will normally be 'true'. ifAlias Refer to [12].-
ifCounterDiscontinuityTime Refer to [12].
ifStackHigherLayer Refer to section 3.2.1. ifStackLowerLayer ifStackStatus ifRcvAddressAddress Refer to section 3.2.4. ifRcvAddressStatus ifRcvAddressType -
3.3. Relation to the 802.3 MAU MIB
-
Support for the mauModIfCompl compliance statement of the MAU-MIB [14] is REQUIRED for Ethernet-like interfaces. This MIB is needed in order to allow applications to determine the current MAU type in use by the interface. The MAU type indicates not only the media type in use, but also indicates whether the interface is operating in half- duplex or full-duplex mode. Implementing this MIB module without implementing the MAU-MIB would leave applications with no standard way to determine the duplex mode of the interface.

STATUS current DESCRIPTION "This test configures the MAC chip and executes an internal loopback test of memory, data paths, and the MAC chip logic. This loopback test can only be executed if the interface is offline. Once the test has completed, the MAC chip should be reinitialized for network operation, but it should remain offline. If an error occurs during a test, the appropriate test result object will be set to indicate a failure.

6. Acknowledgements

This document was produced by the 802.3 Hub MIB Working Group.
This document is almost completely based on both the Standard Ethernet MIB, RFC 1643 [10], and the Proposed Standard Ethernet MIB using the SNMPv2 SMI, RFC 1650 [11], both of which were edited by Frank Kastenholz of FTP Software and produced by the Ethernet MIB Working Group. This document extends those documents by providing support for 100 Mb/sec ethernet interfaces as outlined in [6].
RFC 1643 and RFC 1650, in turn, are based on the Draft Standard Ethernet MIB, RFC 1398 [9], also edited by Frank Kastenholz and produced by the Ethernet MIB Working Group.
RFC 1398, in turn, is based on the Proposed Standard Ethernet MIB, RFC 1284 [8], which was edited by John Cook of Chipcom and produced by the Transmission MIB Working Group. The Ethernet MIB Working Group gathered implementation experience of the variables specified in RFC 1284 and used that information to develop this revised MIB.
RFC 1284, in turn, is based on a document written by Frank Kastenholz, then of Interlan, entitled IEEE 802.3 Layer Management Draft M compatible MIB for TCP/IP Networks [7]. 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. Thanks to Frank Kastenholz of Interlan and Louis Steinberg of IBM for their experimentation.

8. Security Considerations
-
There are no management objects defined in this MIB that have a MAX- ACCESS clause of read-write and/or read-create. So, if this MIB is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB via direct SNMP SET operations.
There are a number of managed objects in this MIB that may be considered to contain sensitive information. In particular, the dot3StatsEtherChipSet object may be considered sensitive in many environments, since it would allow an intruder to obtain information about which vendor's equipment is in use on the network.
Therefore, it may be important in some environments to control read access to these objects and possibly to even encrypt the values of these object when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment.
SNMPv1 by itself is such an insecure 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 (read) the objects in this MIB.
It is recommended that the implementors consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2274 [17] and the View-based Access Control Model RFC 2275 [18] 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 those objects only to those principals (users) that have legitimate rights to access them.
