Module: A3COM-HUAWEI-DOT3-EFM-EPON-MIB
OID (symbolic): A3COM-HUAWEI-DOT3-EFM-EPON-MIB::h3cDot3OmpEmulationCRC8Errors
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.2.2.1.2.1.2
Node type: OBJECT-TYPE
Type: Counter32
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 attribute is mandatory for an OLT and for an ONU.
What is h3cDot3OmpEmulationCRC8Errors?
Counts frames with valid SLD but failed CRC-8 checksum validation, mandatory for both OLT and ONU. This indicates bit errors in received frames; engineers escalate when counts climb, signaling fiber or transceiver problems. A value of 31 over 10 minutes warrants ONU-to-OLT link inspection.
