sDot3StatsSymbolErrors
Module: GBNDeviceSWAPI-MIB
OID (symbolic): GBNDeviceSWAPI-MIB::sDot3StatsSymbolErrors
OID (numeric): 1.3.6.1.4.1.13464.1.2.2.2.9.1.2.1.18
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: For an interface operating at 100 Mb/s, the number of times there was an invalid data symbol when a valid carrier was present.
For an interface operating in half-duplex mode at 1000 Mb/s, the number of times the receiving media is non-idle (a carrier event) for a period of time equal to or greater than slotTime, and during which there was at least one occurrence of an event that causes the PHY to indicate 'Data reception error' or 'carrier extend error' on the GMII.
For an interface operating in full-duplex mode at 1000 Mb/s, the number of times the receiving media is non-idle a carrier event) for a period of time equal to or greater than minFrameSize, and during which there was at least one occurrence of an event that causes the PHY to indicate 'Data reception error' on the GMII.
The count represented by an instance of this object is incremented at most once per carrier event, even if multiple symbol errors occur during the carrier event. This count does not increment if a collision is present.
Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is sDot3StatsSymbolErrors?
At 100 Mb/s counts invalid data symbols seen while a carrier was present; at 1000 Mb/s it instead counts carrier events flagged with a PHY-level data-reception error. Either way, a rising count points to a physical-layer signal-quality problem on the link.
