Common enumeration values for repeater and interface MAU jack types. Table of descriptive and status information about the MAU(s) attached to the ports of a repeater. An entry in the table, containing information about a single MAU. readonly This variable uniquely identifies the group containing the port to which the MAU described by this entry is connected. Note: In practice, a group will generally be a field-replaceable unit (i.e., module, card, or board) that can fit in the physical system enclosure, and the group number will correspond to a number marked on the physical enclosure. The group denoted by a particular value of this object is the same as the group denoted by the same value of rptrGroupIndex. RFC 2108, rptrGroupIndex. readonly This variable uniquely identifies the repeater port within group rpMauGroupIndex to which the MAU described by this entry is connected. RFC 2108, rptrPortIndex. readonly This variable uniquely identifies the MAU described by this entry from among other MAUs connected to the same port (rpMauPortIndex). [IEEE802.3], 30.5.1.1.1, aMAUID. readonly This object identifies the MAU type. Values for standard IEEE 802.3 MAU types are defined in the IANA maintained IANA-MAU-MIB module, as OBJECT-IDENTITIES of dot3MauType. If the MAU type is unknown, the object identifier zeroDotZero is returned. [IEEE802.3], 30.5.1.1.2, aMAUType. readwrite The current state of the MAU. 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; it 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 assume the respective state, except that setting a mixing-type MAU or an AUI to standby(4) will cause the MAU to enter the shutdown state.

[IEEE802.3], 30.5.1.1.5, aLoseMediaCounter. RFC 2108, rptrMonitorPortLastChange readonly The value other(1) is returned if the jabber state is not 2, 3, or 4. The agent MUST always return other(1) for MAU type dot3MauTypeAUI. The value unknown(2) is returned when the MAU's true state is unknown; for example, when it is being initialized. If the MAU is not jabbering the agent returns noJabber(3). This is the 'normal' state. If the MAU is in jabber state the agent returns the jabbering(4) value. [IEEE802.3], 30.5.1.1.6, aJabber.jabberFlag. readonly A count of the number of times that mauJabberState for this MAU instance enters the state jabbering(4). For MAUs of type dot3MauTypeAUI, dot3MauType100BaseT4, dot3MauType100BaseTX, dot3MauType100BaseFX, and all 1000Mbps types, this counter will always indicate zero.

[IEEE802.3], 30.5.1.1.6, aJabber.jabberCounter. RFC 2108, rptrMonitorPortLastChange readonly A count of the number of false carrier events during IDLE in 100BASE-X links. This counter does not increment at the symbol rate. It can increment after a valid carrier completion at a maximum rate of once per 100 ms until the next carrier event. This counter increments only for MAUs of type dot3MauType100BaseT4, dot3MauType100BaseTX, dot3MauType100BaseFX, and all 1000Mbps types.

[IEEE802.3], 30.5.1.1.10, aFalseCarriers. RFC 2863, ifCounterDiscontinuityTime. readonly ********* THIS OBJECT IS DEPRECATED ********** This object has been deprecated in favour of ifMauTypeListBits. A value that uniquely identifies the set of possible IEEE 802.3 types that the MAU could be. The value is a sum that initially takes the value zero. Then, for each type capability of this MAU, 2 raised to the power noted below is added to the sum. For example, a MAU that has the capability to be only 10BASE-T would have a value of 512 (2**9). In contrast, a MAU that supports both 10Base-T (full duplex) and 100BASE-TX (full duplex) would have a value of ((2**11) + (2**16)), or 67584. The powers of 2 assigned to the capabilities are these: Power Capability 0 other or unknown 1 AUI 2 10BASE-5 3 FOIRL 4 10BASE-2 5 10BASE-T duplex mode unknown 6 10BASE-FP 7 10BASE-FB 8 10BASE-FL duplex mode unknown 9 10BROAD36 10 10BASE-T half duplex mode 11 10BASE-T full duplex mode 12 10BASE-FL half duplex mode 13 10BASE-FL full duplex mode 14 100BASE-T4 15 100BASE-TX half duplex mode 16 100BASE-TX full duplex mode 17 100BASE-FX half duplex mode 18 100BASE-FX full duplex mode 19 100BASE-T2 half duplex mode 20 100BASE-T2 full duplex mode If auto-negotiation is present on this MAU, this object will map to ifMauAutoNegCapability. readwrite This object identifies the default administrative baseband MAU type to be used in conjunction with the operational MAU type denoted by ifMauType. The set of possible values for this object is the same as the set defined for the ifMauType object. This object represents the administratively-configured type of the MAU. If auto-negotiation is not enabled or is not implemented for this MAU, the value of this object determines the operational type of the MAU. In this case, a set to this object will force the MAU into the specified operating mode. If auto-negotiation is implemented and enabled for this MAU, the operational type of the MAU is determined by auto-negotiation, and the value of this object denotes the type to which the MAU will automatically revert if/when auto-negotiation is later disabled. NOTE TO IMPLEMENTORS: It may be necessary to provide for underlying hardware implementations which do not follow the exact behavior specified above. In particular, when ifMauAutoNegAdminStatus transitions from enabled to disabled, the agent implementation MUST ensure that the operational type of the MAU (as reported by ifMauType) correctly transitions to the value specified by this object, rather than continuing to operate at the value earlier determined by the auto-negotiation function.

If auto-negotiation is present on this MAU, this object will map to ifMauAutoNegCapabilityBits. Note that this MAU may be capable of operating as a MAU type that is beyond the scope of this MIB. This is indicated by returning the bit value bOther in addition to any bit values for standard capabilities that are listed in the IANAifMauTypeListBits TC. readonly A count of the number of false carrier events during IDLE in 100BASE-X and 1000BASE-X links. For all other MAU types, this counter will always indicate zero. This counter does not increment at the symbol rate. This counter is a 64-bit version of ifMauFalseCarriers. Since the 32-bit version of this counter can roll over very quickly, management stations are advised to poll the 64-bit version instead, in order to avoid loss of information. Discontinuities in the value of this counter can occur at re-initialization of the management system and at other times, as indicated by the value of ifCounterDiscontinuityTime. [IEEE802.3], 30.5.1.1.10, aFalseCarriers. RFC 2863, ifCounterDiscontinuityTime.

Configuration and status objects for the auto-negotiation function of MAUs attached to interfaces. The ifMauAutoNegTable applies to systems in which auto-negotiation is supported on one or more MAUs attached to interfaces. Note that if auto-negotiation is present and enabled, the ifMauType object reflects the result of the auto-negotiation function. An entry in the table, containing configuration and status information for the auto-negotiation function of a particular MAU. readwrite Setting this object to enabled(1) will cause the interface that has the auto-negotiation signaling ability to be enabled. If the value of this object is disabled(2) then the interface will act as it would if it had no auto-negotiation signaling. Under these conditions, an IEEE 802.3 MAU will immediately be forced to the state indicated by the value of the object ifMauDefaultType. NOTE TO IMPLEMENTORS: When ifMauAutoNegAdminStatus transitions from enabled to disabled, the agent implementation MUST ensure that the operational type of the MAU (as reported by ifMauType) correctly transitions to the value specified by the ifMauDefaultType object, rather than continuing to operate at the value earlier determined by the auto-negotiation function.
