dot3EponFecCorrectedBlocks

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3EponFecCorrectedBlocks

OID (numeric): 1.3.6.1.2.1.155.1.3.1.1.4

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: For 10PASS-TS, 2BASE-TL, and 1000BASE-PX PHYs, it is a count of corrected FEC blocks. This counter will not increment for other PHY Types. Increment the counter by one for each received block that is corrected by the FEC function in the PHY. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface. Discontinuities of this counter can occur at re-initialization of the management system and at other times, as indicated by the value of the

ifCounterDiscontinuityTime object of the Interface MIB module.

What is dot3EponFecCorrectedBlocks?

This counts FEC blocks that were successfully corrected by the PHY's forward-error-correction function; it stays at zero whenever FEC receive is not enabled. A high correction rate on an otherwise-working link can be an early warning of a degrading optical path before uncorrectable errors start appearing.
