dot3MpcpTxRegAck

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3MpcpTxRegAck

OID (numeric): 1.3.6.1.2.1.155.1.1.2.1.7

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: A count of the number of times a REGISTER_ACK MPCP frame transmission occurs. Increment the counter by one for each REGISTER_ACK MPCP frame transmitted 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 OLT, 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 dot3MpcpTxRegAck?

This counts REGISTER_ACK MPCP frames transmitted on this interface, the acknowledgment the OLT sends confirming an ONU's registration (expected zero at the OLT side per the module's convention). Admins use it together with dot3MpcpRxRegRequest to confirm the registration handshake is actually completing.
