11Configuring link monitoringNOTE:After Ethernet OAM connections are established, the link monitoring periods and thresholds configured inthis section take effect on all Ethernet ports automatically.Configuring errored symbol event detectionAn errored symbol event occurs when the number of detected symbol errors over a specific detectioninterval exceeds the configured threshold.Follow these steps to configure errored symbol event detection:To do… Use the command… RemarksEnter system view system-view —Configure the erroredsymbol event detectionintervaloam errored-symbol period period-value Optional1 second by defaultConfigure the erroredsymbol event triggeringthresholdoam errored-symbol thresholdthreshold-valueOptional1 by defaultConfiguring errored frame event detectionAn errored frame event occurs when the number of detected error frames over a specific interval exceedsthe configured threshold.Follow these steps to configure errored frame event detection:To do… Use the command… RemarksEnter system view system-view —Configure the errored frameevent detection interval oam errored-frame period period-value Optional1 second by defaultConfigure the errored frameevent triggering thresholdoam errored-frame thresholdthreshold-valueOptional1 by defaultConfiguring errored frame period event detectionAn errored frame period event occurs if the number of frame errors in specific number of received framesexceeds the configured threshold.Follow these steps to configure errored frame period event detection:To do… Use the command… RemarksEnter system view system-view —Configure the errored frameperiod event detectionperiodoam errored-frame-period periodperiod-valueOptional1000 milliseconds by default
