Through the following configuration, you can establish the collaboration between the track module and 

the NQA, which probes the link status and informs the track module of the probe result.  

Follow these steps to configure Track-NQA collaboration: 

Enter system view 

— 

Create a track entry, associate 
it with the specified reaction 
entry of the NQA test group, 
and specify the delay time for 
the track module to notify the 
application modules 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 that is 
associated with the specified 
reaction entry of an NQA test 
group is created by default. 

 

When you configure a track entry, the specified NQA test group and reaction entry can be nonexistent. 

In this case, the status of the configured track entry is Invalid. 

 

Through the following configuration, you can establish the collaboration between the track module and 

BFD, which probes the link status by sending echo packets and informs the track module of the probe 

result. 

Before configuring track-BFD collaboration, configure the source address of the BFD echo packets. 

Refer to BFD Configuration in the High Availability Volume for details. 

Follow these steps to configure Track-BFD collaboration: 

Enter system view 

— 

Create a track entry, associate 
it with the BFD session, and 
specify the delay time for the 
track module to notify the 
application modules when the 
track entry status changes 

track track-entry-number bfd 
echo interface interface-type 
interface-number remote ip 
remote-ip local ip local-ip 
[ delay { negative 
negative-time | positive 
positive-time } * ] 

Required 

No track entry that is 
associated with the BFD 
session is created by default.
