27Step Command Remarks2. Create an NQA operationand enter NQA operationview.nqa entry admin-nameoperation-tagBy default, no NQA operation iscreated.3. Specify an NQA operationtype and enter its view.type { dhcp | dlsw | dns | ftp |http | icmp-echo | snmp | tcp |udp-echo }The collaboration function is notavailable for the path jitter, UDPtracert, UDP jitter, and voiceoperations.4. Configure a reaction entry.reaction item-numberchecked-element probe-failthreshold-type consecutiveconsecutive-occurrencesaction-type trigger-onlyBy default, no reaction entry isconfigured.You cannot modify the content ofan existing reaction entry.5.

N/AConfiguring threshold monitoringThis function allows you to monitor the NQA operation running status.Threshold typesAn NQA operation supports the following threshold types:• average—If the average value for the monitored performance metric either exceeds the upperthreshold or goes below the lower threshold, a threshold violation occurs.• accumulate—If the total number of times that the monitored performance metric is out of thespecified value range reaches or exceeds the specified threshold, a threshold violation occurs.• consecutive—If the number of consecutive times that the monitored performance metric is out of thespecified value range reaches or exceeds the specified threshold, a threshold violation occurs.Threshold violations for the average or accumulate threshold type are determined on a per NQAoperation basis. The threshold violations for the consecutive type are determined from the time the NQAoperation starts.Triggered actionsThe following actions might be triggered:• none—NQA displays results only on the terminal screen. It does not send traps to the NMS.• trap-only—NQA displays results on the terminal screen, and meanwhile it sends traps to the NMS.• trigger-only—NQA displays results on the terminal screen, and meanwhile triggers other modulesfor collaboration.The DNS operation does not support the action of sending trap messages.Reaction entryIn a reaction entry, configure a monitored element, a threshold type, and an action to be triggered toimplement threshold monitoring.
