Associating the track module with a detection
module
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 normally. The track module then sets the track entry to the Positive state.
For more information about NQA, see Network Management and Monitoring Configuration Guide.
Follow these steps to associate track with NQA:

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

Required
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.
Associating track with BFD
BFD supports the control packet mode and echo mode. Only echo-mode BFD can be associated with a
track entry.
The BFD functions as follows when it is associated with a track entry:
