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. Then the Track module 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 specify
the delay time for the Track
module to notify the
associated application
module when the track entry
status changes.

{

|
positive

} * ]
By default, no track entry is
created.
If the specified NQA operation or
the reaction entry in the track
entry does not exist, the status of
the track entry is NotReady.
Associating Track with BFD
BFD supports the control packet mode and echo packet mode. A track entry can be associated only
with the echo-mode BFD session. For more information about BFD, see "Configuring BFD."
The associated Track and BFD operate as follows:
• If the BFD detects that the link fails, it informs the Track module of the link failure. The Track
module sets the track entry to Negative state.
• If the BFD detects that the link is operating correctly, the Track module sets the track entry to
Positive state.
Before you associate Track with BFD, configure the source IP address of BFD echo packets. For
more information, see "Configuring BFD."
