Module: A3COM-HUAWEI-DOT3-EFM-EPON-MIB

OID (symbolic): A3COM-HUAWEI-DOT3-EFM-EPON-MIB::h3cDot3EponMauFECUncorrectableBlocks

OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.2.3.1.1.1.5

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: For 10PASS-TS, 2BASE-TL and 1000BASE-PX PHYs, a count of uncorrectable FEC blocks. This counter will not increment for other PHY Types. Increment the counter by one for each FEC block that is determined to be uncorrectable by the FEC function in the PHY.

What is h3cDot3EponMauFECUncorrectableBlocks?

This counter32 counts data blocks that FEC could not fix and were lost. Network engineers watch this metric to detect line degradation beyond FEC's capability. A non-zero value signals serious channel problems requiring technician investigation.
