erptrMauMediaPolarityStatus
Module: DECHUB900-ERPTR-MIB-V3-0
OID (symbolic): DECHUB900-ERPTR-MIB-V3-0::erptrMauMediaPolarityStatus
OID (numeric): 1.3.6.1.4.1.36.2.18.11.5.1.1.5.3.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: A value of polarityNotReversed(1) indicates that the MAU senses that received data packet waveform polarity is correct.
A value of polarityReversed(2) indicates that the MAU senses that received data packet waveform polarity is incorrect (i.e. reversed). Reversed polarity may indicate a wiring error, especially on 10Base-T links.
A value of polarityCorrected(3) indicates that the MAU senses that received data packet waveform polarity is incorrect (i.e reversed, perhaps due to a wiring error) but the MAU has automatically corrected the polarity error.
A value of unknown(4) indicates that the MAU does not have the ability to detect whether or not received data packet waveform polarity is correct.
What is erptrMauMediaPolarityStatus?
This reports whether the MAU is sensing correct receive-signal polarity: polarityNotReversed(1) is normal, polarityReversed(2) usually indicates a wiring error (especially on 10Base-T), polarityCorrected(3) means the MAU detected reversed polarity but auto-fixed it, and unknown(4) means the MAU can't detect polarity at all. A reversed-polarity reading is a good first thing to check when a 10Base-T link is flaky.
