dot3MpcpRxRegAck
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3MpcpRxRegAck
OID (numeric): 1.3.6.1.2.1.155.1.1.2.1.8
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: A count of the number of times a REGISTER_ACK MPCP frame reception occurs. Increment the counter by one for each REGISTER_ACK MPCP frame received as defined in [802.3ah], clause 64. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface. At the ONU, the value should be zero. 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 dot3MpcpRxRegAck?
This counts REGISTER_ACK MPCP frames received on this interface, i.e. registration acknowledgments seen by an ONU from its OLT (expected zero at the OLT side). If an ONU keeps sending REGISTER_REQ but this counter never increments, the ONU isn't getting acknowledged and won't reach the registered state.
