RFC 2239 Managed Objects for IEEE 802.3 MAUs November 1997 Abstract This memo defines an portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines objects for managing 10 and 100 Mb/second Medium Attachment Units (MAUs) based on IEEE Std 802.3 Section 30, "10 & 100 Mb/s Management," October 26, 1995. 1. 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 [6] - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, STD 17, RFC 1213 [5] - the core set of managed objects for the Internet suite of protocols. o the protocol, STD 15, RFC 1157 [10] and/or RFC 1905 [9] - the protocol used for accessing managed information. Textual conventions are defined in RFC 1903 [7], and conformance statements are defined in RFC 1904 [8]. 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) 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. de Graaf, et. al. Standards Track [Page 2]
RFC 2239 Managed Objects for IEEE 802.3 MAUs November 1997 2. Overview 2.1. Relationship to RFC 1515 This MIB is intended to be a superset of that defined by RFC 1515 [11], which will go to historic status. This MIB includes all of the objects contained in that MIB, plus several new ones which provide additional capabilities. Implementors are encouraged to support all applicable conformance groups in order to make the best use of the new functionality provided by this MIB. The new objects provide management support for: o management of 100 Mb/s devices o auto-negotiation on interface MAUs o jack management 2.2. MAU Management Instances of these object types represent attributes of an IEEE 802.3 MAU. Several types of MAUs are defined in the IEEE 802.3 CSMA/CD standard [1] and [2]. These MAUs may be connected to IEEE 802.3 repeaters or to 802.3 (Ethernet-like) interfaces. For convenience this document refers to these devices as "repeater MAUs" and "interface MAUs." The definitions presented here are based on Section 30.5, "Layer Management for 10 & 100 Mb/s Medium Attachment Units (MAUs)", and Annex 30A, "GDMO Specifications for 802.3 managed objects" of IEEE Std 802.3u-1995. That specification includes definitions for both 10Mb/s and 100Mb/s devices, and is essentially a superset of the 10Mb/s definitions given by IEEE 802.3 Section 20. This specification is intended to serve the same purpose: to provide for management of both 10Mb/s and 100Mb/s MAUs. 2.3. Relationship to Other MIBs It is assumed that an agent implementing this MIB will also implement (at least) the 'system' group defined in MIB-II [5]. The following sections identify other MIBs that such an agent should implement. 2.3.1. Relationship to the MIB-II 'interfaces' group The sections of this document that define interface MAU-related objects specify an extension to the 'interfaces' group of MIB-II. An agent implementing these interface-MAU related objects must also de Graaf, et. al. Standards Track [Page 3]
RFC 2239 Managed Objects for IEEE 802.3 MAUs November 1997 implement the 'interfaces' group of MIB-II. The value of the object ifMauIfIndex is the same as the value of 'ifIndex' used to instantiate the interface to which the given MAU is connected. It is expected that an agent implementing the interface-MAU related objects in this MIB will also implement the Ethernet- like Interfaces MIB, RFC 1650. (Note that repeater ports are not represented as interfaces in the sense of MIB-II's 'interfaces' group.) 2.3.2. Relationship to the 802.3 Repeater MIB The section of this document that defines repeater MAU-related objects specifies an extension to the 802.3 Repeater MIB defined in [4]. An agent implementing these repeater-MAU related objects must also implement the 802.3 Repeater MIB. The values of 'rpMauGroupIndex' and 'rpMauPortIndex' used to instantiate a repeater MAU variable shall be the same as the values of 'rptrPortGroupIndex' and 'rptrPortIndex' used to instantiate the port to which the given MAU is connected. 2.4. Management of Internal MAUs In some situations, a MAU can be "internal" -- i.e., its functionality is implemented entirely within a device. For example, a managed repeater may contain an internal repeater- MAU and/or an internal interface-MAU through which management communications originating on one of the repeater's external ports pass in order to reach the management agent associated with the repeater. Such internal MAUs may or may not be managed. If they are managed, objects describing their attributes should appear in the appropriate MIB subtree: dot3RpMauBasicGroup for internal repeater-MAUs and dot3IfMauBasicGroup for internal interface-MAUs. 3.

This object may be implemented as a read-only object by those agents and MAUs that do not implement software control of the MAU state. Some agents may not support setting the value of this object to some of the enumerated values. The value other(1) is returned if the MAU is in a state other than one of the states 2 through 6. The value unknown(2) is returned when the MAU's true state is unknown; for example, when it is being initialized. A MAU in the operational(3) state is fully functional, operates, and passes signals to its attached DTE or repeater port in accordance to its specification. A MAU in standby(4) state forces DI and CI to idle and the media transmitter to idle or fault, if supported. Standby(4) mode only applies to link type MAUs. The state of rpMauMediaAvailable is unaffected. A MAU in shutdown(5) state assumes the same condition on DI, CI, and the media transmitter as though it were powered down or not connected. The MAU may return other(1) value for the rpMauJabberState and rpMauMediaAvailable objects when it is in this state. For an AUI, this state will remove power from the AUI. Setting this variable to the value reset(6) resets the MAU in the same manner as a power-off, power- on cycle of at least one-half second would. The agent is not required to return the value reset (6). Setting this variable to the value operational(3), standby(4), or shutdown(5) causes the MAU to de Graaf, et. al. Standards Track [Page 12]

For an AUI or a coax (including broadband) MAU this indicates whether or not loopback is detected on the DI circuit. The value of this attribute persists between packets for MAU types AUI, 10BASE5, 10BASE2, 10BROAD36, and 10BASE-FP. The value other(1) is returned if the mediaAvailable state is not one of 2 through 6. The value unknown(2) is returned when the MAU's true state is unknown; for example, when it is being initialized. At power-up or following a reset, the value of this attribute will be unknown for AUI, coax, and 10BASE-FP MAUs. For these MAUs loopback will be tested on each transmission during which no collision is detected. If DI is receiving input when DO returns to IDL after a transmission and there has been no collision during the transmission then loopback will be detected. The value of this attribute will only change during non-collided transmissions for AUI, de Graaf, et. al. Standards Track [Page 13]
RFC 2239 Managed Objects for IEEE 802.3 MAUs November 1997 coax, and 10BASE-FP MAUs. For 100BASE-T4, 100BASE-TX and 100BASE-FX the enumerations match the states within the respective link integrity state diagrams, fig 23- 12 and 24-15 of sections 23 and 24 of [2]. Any MAU which implements management of auto- negotiation will map remote fault indication to remote fault. The value available(3) indicates that the link, light, or loopback is normal. The value notAvailable(4) indicates link loss, low light, or no loopback. The value remoteFault(5) indicates that a fault has been detected at the remote end of the link. This value applies to 10BASE-FB, 100BASE-T4 Far End Fault Indication and non-specified remote faults from a system running auto-negotiation. The values remoteJabber(7), remoteLinkLoss(8), and remoteTest(9) should be used instead of remoteFault(5) where the reason for remote fault is identified in the remote signaling protocol. The value invalidSignal(6) indicates that an invalid signal has been received from the other end of the link. InvalidSignal(6) applies only to MAUs of type 10BASE-FB. Where an IEEE Std 802.3u-1995 clause 22 MII is present, a logic one in the remote fault bit (reference section 22.2.4.2.8 of that document) maps to the value remoteFault(5), and a logic zero in the link status bit (reference section 22.2.4.2.10 of that document) maps to the value notAvailable(4). The value notAvailable(4) takes precedence over the value remoteFault(5)."

The state of ifMauMediaAvailable is unaffected. A MAU in shutdown(5) state assumes the same condition on DI, CI, and the media transmitter as though it were powered down or not connected. The MAU may return other(1) value for the ifMauJabberState and ifMauMediaAvailable objects when it is in this state. For an AUI, this state will remove power from the AUI. Setting this variable to the value reset(6) resets the MAU in the same manner as a power-off, power- on cycle of at least one-half second would. The agent is not required to return the value reset (6). Setting this variable to the value operational(3), standby(4), or shutdown(5) causes the MAU to de Graaf, et. al. Standards Track [Page 20]

For an AUI or a coax (including broadband) MAU this indicates whether or not loopback is detected on the DI circuit. The value of this attribute persists between packets for MAU types AUI, 10BASE5, 10BASE2, 10BROAD36, and 10BASE-FP. The value other(1) is returned if the mediaAvailable state is not one of 2 through 6. The value unknown(2) is returned when the MAU's true state is unknown; for example, when it is being initialized. At power-up or following a reset, the value of this attribute will be unknown for AUI, coax, and 10BASE-FP MAUs. For these MAUs loopback will be tested on each transmission during which no collision is detected. If DI is receiving input when DO returns to IDL after a transmission and there has been no collision during the transmission then loopback will be detected. The value of this attribute will only change during non-collided transmissions for AUI, de Graaf, et. al. Standards Track [Page 21]

For 100BASE-T4, 100BASE-TX and 100BASE-FX the enumerations match the states within the respective link integrity state diagrams, fig 23- 12 and 24-15 of sections 23 and 24 of [2]. Any MAU which implements management of auto- negotiation will map remote fault indication to remote fault. The value available(3) indicates that the link, light, or loopback is normal. The value notAvailable(4) indicates link loss, low light, or no loopback. The value remoteFault(5) indicates that a fault has been detected at the remote end of the link. This value applies to 10BASE-FB, 100BASE-T4 Far End Fault Indication and non-specified remote faults from a system running auto-negotiation. The values remoteJabber(7), remoteLinkLoss(8), and remoteTest(9) should be used instead of remoteFault(5) where the reason for remote fault is identified in the remote signaling protocol. The value invalidSignal(6) indicates that an invalid signal has been received from the other end of the link. InvalidSignal(6) applies only to MAUs of type 10BASE-FB. Where an IEEE Std 802.3u-1995 clause 22 MII is present, a logic one in the remote fault bit (reference section 22.2.4.2.8 of that document) maps to the value remoteFault(5), and a logic zero in the link status bit (reference section 22.2.4.2.10 of that document) maps to the value notAvailable(4).

RFC 2239 Managed Objects for IEEE 802.3 MAUs November 1997 6. Security Considerations Certain management information defined in this MIB may be considered sensitive in some network environments. Therefore, authentication of received SNMP requests and controlled access to management information should be employed in such environments. The method for this authentication is a function of the SNMP Administrative Framework, and has not been expanded by this MIB. Several objects in this MIB allow write access. Setting these objects can have a serious effect on the operation of the network, including enabling or disabling a MAU, changing a MAU's default type, enabling, disabling or restarting autonegotiation, or modifying the capabilities that a MAU advertizes during autonegotiation. It is recommended that implementers seriously consider whether set operations should be allowed without providing, at a minimum, authentication of request origin. 7.
