Associating Track with NQA
NQA supports multiple test types to analyze network performance, services, service quality. For
example, an NQA test group can periodically detect whether a destination is reachable, or whether
the TCP connection to a TCP server can be set up.
An NQA test group functions as follows when it is associated with a track entry:
 If the consecutive failures reach the specified threshold, the NQA module tells the Track module
that the tracked object malfunctions. Then the Track module sets the track entry to the Negative
state.
 If the specified threshold is not reached, the NQA module tells the Track module that the tracked
object functions correctly. The Track module then sets the track entry to the 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 specify
the delay time for the Track
module to notify the
associated application
module when the track entry
status changes.
track track-entry-number nqa entry
admin-name operation-tag
reaction item-number [ delay
{ negative negative-time | positive
positive-time } * ]
No track entry is created by
default.
NOTE:
If the specified NQA test group or the reaction entry in the track entry does not exist, the status of the track
entry is Invalid.
