dot3MpcpDiscoveryTimeout
Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3MpcpDiscoveryTimeout
OID (numeric): 1.3.6.1.2.1.155.1.1.2.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of the number of times a discovery timeout occurs. Increment the counter by one for each discovery processing state-machine reset resulting from timeout waiting for message arrival. 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 dot3MpcpDiscoveryTimeout?
This counts how many times the discovery state machine reset due to a timeout waiting for a registration message to arrive. Frequent increments point to an ONU that keeps starting registration but never completing it, often from an optical or timing problem on that link.
