dot3OmpEmulationCRC8Errors
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3OmpEmulationCRC8Errors
OID (numeric): 1.3.6.1.2.1.155.1.2.2.1.2
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: A count of frames received that contain a valid SLD field, as defined in [802.3ah], clause 65.1.3.3.1, but do not pass the CRC-8 check as defined in [802.3ah], clause 65.1.3.3.3. 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 dot3OmpEmulationCRC8Errors?
This counts frames that had a valid SLD field but failed the CRC-8 integrity check defined in [802.3ah] clause 65.1.3.3.3. Rising values here, distinct from SLD errors, suggest bit corruption in the LLID header itself rather than a total framing failure.
