Task Remarks
Associating Track with interface management
Associating the Track module
with an application module
Associating Track with VRRP
Required.
Use one of the
methods.
Associating Track with static routing
Associating Track with PBR
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.
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 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 correctly. 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:
Ste
p
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 trac
k
entry is Invalid.
Associating Track with BFD
BFD supports the control packet mode and echo packet mode. You can only associate a track entry with
the echo-mode BFD session to detect a directly connected link. Before that, you must configure the source
IP address of BFD echo packets.
