3. Specify an NQA operation
type and enter its view.
type { dhcp | dlsw | dns | ftp |
http | icmp-echo | snmp | tcp |
udp-echo }
The collaboration function is not
available for the path jitter, UDP
jitter, and voice operations.
4. Configure a reaction entry.
reaction item-number

action-type trigger-only
By default, no reaction entry is
configured.
You cannot modify the content of
an existing reaction entry.
5. Exit to system view.

Configuring threshold monitoring
Threshold types
An NQA operation supports the following threshold types:
• average—If the average value for the monitored performance metric either exceeds the upper
threshold 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 the
specified 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 the
specified 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 NQA
operation basis, and threshold violations for the consecutive type are determined from the time the NQA
operation starts.
Triggered actions
The 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 modules
for collaboration.
The DNS operation does not support the action of sending trap messages.
Reaction entry
In a reaction entry, a monitored element, a threshold type, and an action to be triggered are configured
to implement threshold monitoring.
The state of a reaction entry can be invalid, over-threshold, or below-threshold.
• Before an NQA operation starts, the reaction entry is in invalid state.
• If the threshold is violated, the state of the entry is set to over-threshold. Otherwise, the state of the
entry is set to below-threshold.
