Collaboration between the track module and an application module
After being associated with an application module, when the status of the track entry changes, the track
module notifies the application module, which then takes proper actions.
Only static routing can be associated with the track module.
Collaboration application example
The following is an example of collaboration between NQA, track, and static routing.
Configure a static route with next hop 192.168.0.88 on the device. If the next hop is reachable, the static
route is valid. If the next hop becomes unreachable, the static route should become invalid. For this
purpose, configure collaboration between the NQA, track, and static routing modules:
1. Create an NQA test group to monitor the reachability of IP address 192.168.0.88.
2. Create a track entry and associate it with the NQA test group. When the next hop 192.168.0.88
is reachable, the track entry is in Positive state. When the next hop becomes unreachable, the track
entry is in Negative state.
3. Associate the track entry with the static route. When the track entry turns to the Positive state, the
static route is valid. When the associated track entry turns to the Negative state, the static route is
invalid.
Track configuration task list
To implement the collaboration function, establish associations between the track module and the
detection modules, and between the track module and the application modules.
Complete these tasks to configure the track 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:
