Associating track with NQA
An NQA test group periodically detects whether a destination is reachable, or whether the TCP
connection to a TCP server can be set up. When associated with a track entry, an NQA test group
functions as follows:
•
If the consecutive failure times exceed the specified threshold, the NQA module tells the track
module that the tracked object is unreachable. 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 the
Network Management and Monitoring Configuration Guide
.
