This indicates the reason for the last link failure. liStatus indicates that the daughter board status has changed. liImplicitIncident indicates that a condition which may cause the recognition of a link incident in the attached node has been recognized. liBERthreshold indicates that the code violation error rate exceeded the threshold. liSignalOrSyncLoss indicates a loss of signal or loss of synchronization that persisted longer than the link interval duration. liNotOperationalSequence indicates the recognition of not-operational sequence, usually due to the operator taking the channel offline. liSequenceTimeout indicates a connection recovery timeout or response timeout occurring while in transmit OLS state. linvalidSequence indicates a UD or UDR sequence was recognized while in wait-for-offline-sequence state.
