dot3EponFecBufferHeadCodingViolation
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3EponFecBufferHeadCodingViolation
OID (numeric): 1.3.6.1.2.1.155.1.3.1.1.6
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: For a 1000 Mbps operation, it is a count of the number of invalid code-group received directly from the link. The value has a meaning only in 1000 Mbps mode and it is zero otherwise. 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 dot3EponFecBufferHeadCodingViolation?
This counts invalid code-groups received directly from the link during 1000Mbps operation (meaningless, and zero, at other speeds). It's a finer-grained coding-error counter used alongside dot3EponFecPCSCodingViolation when diagnosing gigabit PON signal integrity issues.
