Module: DOT3-EPON-MIB
OID (symbolic): DOT3-EPON-MIB::dot3MpcpDiscoveryWindowsSent
OID (numeric): 1.3.6.1.2.1.155.1.1.2.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of discovery windows generated. The counter is incremented by one for each generated discovery window. 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 dot3MpcpDiscoveryWindowsSent?
This counts the discovery windows the OLT has generated to let new ONUs register on the PON (expected to be zero at an ONU). A high or rapidly climbing count relative to the number of registered ONUs can indicate ONUs repeatedly failing to complete registration.
