calibrate auto-bandwidth-selection

Function

The calibrate auto-bandwidth-selection { enable | disable } command enables or disables the dynamic bandwidth selection (DBS) function.

The undo calibrate auto-bandwidth-selection command restores the default DBS state.

By default, the DBS function is disabled in the AP group radio view and not configured in the AP radio view. This command takes effect only for 5 GHz radios.

Usage Guidelines

Usage Scenario

In non-high-density indoor scenarios, the DBS function can leverage the radio calibration mechanism to automatically select proper bandwidth, improving the overall system capacity.

Prerequisites

Radio calibration has been enabled using the calibrate enable { auto | manual | schedule time } command.
Automatic channel selection has been enabled using the calibrate auto-channel-select enable command.

Precautions

The DBS function is valid only for 5 GHz radios.
The DBS function is applicable only to indoor APs with omnidirectional antennas. The adjustment effect cannot be ensured for indoor APs with directional antennas and outdoor APs.
The DBS function takes effect only between Fit APs connected to the same AC but not between APs connected to different ACs.
The DBS effect is not obvious for high-density scenarios.

Example
