dot3EponFecPCSCodingViolation
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3EponFecPCSCodingViolation
OID (numeric): 1.3.6.1.2.1.155.1.3.1.1.1
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: For a 100 Mbps operation, it is a count of the number of times an invalid code-group is received, other than the /H/ code-group. For a 1000 Mbps operation, it is a count of the number of times an invalid codegroup is received, other than the /V/ code-group. /H/ denotes a special 4b5b codeword of [802.3] 100 Mbps PCS layer (clause 24), and /V/ denotes a special 8b10b codeword of the [802.3] 1000 Mbps PCS layer (clause 36). 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 dot3EponFecPCSCodingViolation?
This counts invalid PCS code-groups received (other than the expected /H/ or /V/ special codewords, depending on 100Mbps or 1000Mbps operation), unaffected by whether FEC is enabled. Rising counts indicate raw physical-layer signal problems on the optical link independent of any forward-error-correction setting.
