cnpd Threshold Config Entry

1.3.6.1.4.1.9.9.244.1.5.1.1

This entry contains configuration information to set thresholds for the purpose of notifications. The management station is allowed to set thresholds on individual statistics for individual protocols on an interface. If the threshold is breached by the protocol statistic, a new event is written to the cnpdThresholdHistoryTable, which in turn will generate a Notification Event. This function has a hysteresis mechanism to limit the generation of events. This mechanism generates one event as a threshold is crossed in the appropriate direction. No more events are generated for that threshold until the opposite threshold is crossed. This stops repeated Notification events being generated each time the value is sampled, when the value is above the threshold. Instead one notification is sent when the threshold is breached and one notification when the statistic drops below the threshold value again.
