| Description | Current/Last PME link Fault Status. This is a bitmap of
possible conditions. The various bit positions are:
lossOfFraming - Loss of Framing for 10P or
Loss of Sync word for 2B PMD or
Loss of 64/65-octet framing.
snrMgnDefect - SNR margin dropped below the
threshold.
lineAtnDefect - Line Attenuation exceeds the
threshold.
deviceFault - Indicates a vendor-dependent
diagnostic or self-test fault
has been detected.
configInitFailure - Configuration initialization failure,
due to inability of the PME link to
support the configuration profile,
requested during initialization.
protocolInitFailure - Protocol initialization failure, due
to an incompatible protocol used by
the peer PME during init (that could
happen if a peer PMD is a regular
G.SDHSL/VDSL modem instead of a
2BASE-TL/10PASS-TS PME).
This object is intended to supplement ifOperStatus in IF-MIB.
This object holds information about the last fault.
efmCuPmeFltStatus is cleared by the device restart.
In addition, lossOfFraming, configInitFailure, and
protocolInitFailure are cleared by PME init;
deviceFault is cleared by successful diagnostics/test;
snrMgnDefect and lineAtnDefect are cleared by SNR margin
and Line attenuation, respectively, returning to norm and by
PME init.
This object partially maps to the Clause 30 attribute
aPMEStatus.
If a Clause 45 MDIO Interface to the PME is present, then this
object consolidates information from various PMA/PMD
registers, namely: Fault bit in PMA/PMD status 1 register,
10P/2B PMA/PMD link loss register,
10P outgoing indicator bits status register,
10P incoming indicator bits status register,
2B state defects register. |
