The calibrate noise-threshold command specifies the noise floor threshold for triggering radio calibration.
The undo calibrate noise-threshold command restores the default noise floor threshold for triggering radio calibration.
The default noise floor threshold for triggering radio calibration is -75 dBm.

The value is an integer that ranges from -95 to 0, in dBm. |
Usage Scenario
The noise floor indicates the noise strength in the current environment. A high noise floor value will make noise drown out valid data, affecting user services.
The noise floor threshold for triggering radio calibration can be used to determine whether the environment noise is normal. When detecting a noise floor value higher than the threshold, an AP reports a high noise floor message to the AC. The AC then performs radio calibration to avoid channels with high noise floor values to improve user experience.
