Task Remarks
Associating track with interface management
approaches.
Associating the track module
with an application module
Required
Use any of the
approaches.
Associating track with static routing
Associating track with traffic redirection
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. After being associated with a track entry, an NQA test group
tells the track module that the tracked object malfunctions when the consecutive failures reach the
specified threshold. 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.
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.
Associating track with BFD
BFD supports the control packet mode and echo mode. Only echo-mode BFD can be associated with a
track entry.
After being associated with a track entry, the BFD informs the track entry of link failures, and then the
track module sets the track entry to the Negative state. If the BFD detects the link is normal, the track
