Associating Track with NQA
NQA supports multiple operation types to analyze network performance and service quality. For example, an NQA operation can periodically detect whether a destination is reachable, or whether a TCP connection can be established.
An NQA operation operates as follows when it is associated with a track entry:
If the consecutive failures reach the specified threshold, the NQA module notifies the Track module that the tracked object has malfunctioned. The Track module then sets the track entry to negative state.
If the specified threshold is not reached, the NQA module notifies the Track module that the tracked object is operating correctly. The Track module then sets the track entry to positive state.
For more information about NQA, see Network Management and Monitoring Configuration Guide.
To associate Track with NQA:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a track entry, associate it with an NQA reaction entry, and enter its view. | track track-entry-number nqa entry admin-name operation-tag reaction item-number | By default, no track entries exist. If the specified NQA operation or the reaction entry in the track entry does not exist, the status of the track entry is NotReady. |
3. Set the delay for notifying the application module of track entry state changes. | delay { negative negative-time | positive positive-time } * | By default, the Track module notifies the application module immediately when the track entry state changes. |
