Enumeration
If the MAU or interface 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 MAU this indicates whether
or not loopback is detected on the DI circuit.
other(1) is returned if the mediaAvailable state
is not one of 2 through 11.
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 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 and
10BASE-FP MAUs.
For 100Mbps and 1000Mbps MAUs, the enumerations
match the states within the respective link
integrity states. Any MAU which implements
management of auto-negotiation will map remote
fault indication to remote fault.
available(3) indicates that the link, light, or
loopback is normal. The value notAvailable(4)
indicates link loss, low light, or no loopback.
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.
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.
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).
Any MAU that implements management of clause 37
Auto-Negotiation will map the received RF1 and
RF2 bit values for Offline to offline(10), Link
Failure to remoteFault(5) and Auto-Negotiation
Error to autoNegError(11).
