dot3OmpEmulationOnuPonCastLLID

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3OmpEmulationOnuPonCastLLID

OID (numeric): 1.3.6.1.2.1.155.1.2.2.1.5

Node type: OBJECT-TYPE

Type: Counter64

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, pass the CRC-8 check, as defined in [802.3ah], clause 65.1.3.3.3, and meet the rules of acceptance for an ONU defined in [802.3ah], clause 65.1.3.3.2. 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.
