rpMauType OBJECT-TYPE SYNTAX OBJECT IDENTIFIER ACCESS read-only STATUS mandatory DESCRIPTION "This object identifies the 10 Mb/s baseband MAU type. An initial set of MAU types are defined above. The assignment of OBJECT IDENTIFIERs to new types of MAUs is managed by the IANA. If the MAU type is unknown, the object identifier
unknownMauType OBJECT IDENTIFIER ::= { 0 0 }
is returned. Note that unknownMauType is a syntactically valid object identifier, and any conformant implementation of ASN.1 and the BER must be able to generate and recognize this value." REFERENCE "Reference IEEE 802.3 MAU Mgt, 20.2.3.2, aMAUType." ::= { rpMauEntry 4 }
rpMauStatus OBJECT-TYPE
SYNTAX INTEGER { other(1), unknown(2), operational(3), standby(4), shutdown(5), reset(6) } ACCESS read-write STATUS mandatory DESCRIPTION "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, 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 and the media transmitter to idle. 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. The MAU may return other(1) value for the mauJabber 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."

rpMauMediaAvailable OBJECT-TYPE SYNTAX INTEGER { other(1), unknown(2), available(3), notAvailable(4), remoteFault(5), invalidSignal(6) } ACCESS read-only STATUS mandatory DESCRIPTION "If the MAU is a link or fiber type (FOIRL, 10BASE-T, 10BASE-F) then this is equivalent to the link test fail state/low light function. 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, coax, and 10BASE-FP MAUs.
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. The value invalidSignal(6) indicates that an invalid signal has been received from the other end of the link. Both remoteFault(5) and invalidSignal(6) apply only to MAUs of type 10BASE-FB."

rpMauJabberState OBJECT-TYPE SYNTAX INTEGER { other(1), unknown(2), noJabber(3), jabbering(4) } ACCESS read-only STATUS mandatory DESCRIPTION "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." REFERENCE "Reference IEEE 802.3 MAU Mgt, 20.2.3.2, aJabber.jabberFlag." ::= { rpMauEntry 8 }
