Associating Track with NQA

NQA supports multiple test types to analyze network performance, services, and 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 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 functioning 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.

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.
If the specified NQA test group 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 only be associated with
the echo-mode BFD session, and cannot be associated with the control-mode BFD session. For more

information about BFD, see "

Configuring BFD

."

BFD functions as follows when it is associated with a track entry:

If the BFD detects that the link fails, it informs the track entry of the link failure. The Track module sets
the track entry to Negative state.
