If the uplink fails, the AC disables the radio on the AP that associates with the AC. If the uplink recovers,
the AC enables the radio on the AP. For this purpose, configure collaboration between the NQA, Track,
and uplink detection:
1. Configure an NQA test group to check the accessibility of the Device.
2. Create a track entry and associate it with the NQA test group. When the Device is reachable, the
track entry is in Positive state. When the Device becomes unreachable, the track entry is in
Negative state.
3. Associate the track entry with the WLAN uplink detection feature. When the associated track entry
turns to the Negative state, the uplink detection feature disables the radio on the AP so that wireless
clients will not associate with the AP. When the track entry changes to the Positive state, the uplink
detection feature enables the radio on the AP so that wireless clients can associate with the AP.
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:
Task Remarks
Associating the Track module
with a detection module
Associating Track with NQA
Required.
Use one of the methods.
Associating Track with BFD
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 Track with interface backup
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.
