125• NQA• Interface management moduleCollaboration between the track module and an application moduleAfter being associated with an application module, when the status of the track entry changes, the trackmodule notifies the application module, which then takes proper actions.Only static routing can be associated with the track module.Collaboration application exampleThe 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 staticroute is valid. If the next hop becomes unreachable, the static route should become invalid. For thispurpose, 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 192.168.0.88is reachable, the track entry is in Positive state. When the next hop becomes unreachable, the trackentry is in Negative state.3. Associate the track entry with the static route. When the track entry turns to the Positive state, thestatic route is valid. When the associated track entry turns to the Negative state, the static route isinvalid.Track configuration task listTo implement the collaboration function, establish associations between the track module and thedetection modules, and between the track module and the application modules.Complete these tasks to configure the track module:Task RemarksAssociating the track modulewith a detection moduleAssociating track with NQA Required.Use any of theapproaches.Associating track with interface managementAssociating the track modulewith an application module Associating track with static routing Required.Associating the track module with a detectionmoduleAssociating track with NQANQA 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 TCPconnection to a TCP server can be set up.An NQA test group functions as follows when it is associated with a track entry:
