• If the consecutive failures reach the specified threshold, the NQA module tells the track module that
the tracked object malfunctions. 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 chapter “NQA configuration.”
Follow these steps to associate track with NQA:
To do… Use the command…
Remarks
Enter system view system-view —
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-num [ delay { negative
negative-time | positive
positive-time } * ]
Required
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 trac
k
entry is Invalid.
Associating track with interface management
The interface management module monitors the physical status or network-layer protocol status of the
interface. When associated with a track entry, the interface management module functions as follows:
• When the physical or network-layer protocol status of the interface changes to up, the interface
management module informs the track module of the change and the track module sets the track
entry to Positive.
• When the physical or network-layer protocol status of the interface changes to down, the interface
management module informs the track module of the change and the track module sets the track
entry to Negative.
Follow these steps to associate track with interface management:
