dot3OmpEmulationSLDErrors

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3OmpEmulationSLDErrors

OID (numeric): 1.3.6.1.2.1.155.1.2.2.1.1

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: A count of frames received that do not contain a valid SLD field as defined in [802.3ah], clause 65.1.3.3.1. 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 dot3OmpEmulationSLDErrors?

This counts frames received without a valid Start-of-LLID-Delimiter (SLD) field, a low-level framing error on the PON link, with discontinuities possible at system reinit. A climbing count points to a physical-layer or optical signal quality problem on that virtual link.
