(Required.) Associating the Track module with an application module:
• Associating Track with VRRP
• Associating Track with static routing
• Associating Track with PBR
• Associating Track with interface backup
Use one of the
methods.

module
Associating Track with NQA
NQA supports multiple operation types to analyze network performance, services, and service quality.
For example, an NQA operation can periodically detect whether a destination is reachable, or whether
the TCP connection to a TCP server can be set up.
An NQA operation 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. The Track module then 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:

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.

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 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 only be associated with
the echo-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.
