The calibrate auto-channel-select { enable | disable } command enables or disables automatic channel selection.
The undo calibrate auto-channel-select command restores the automatic channel selection state.
By default, the automatic channel selection function is enabled in the AP group radio view and not configured in the AP radio view.
The automatic mode (automatic channel selection) is recommended because you do not need to specify a channel for each radio. The fixed mode provides users with an alternative way when they want to specify channels by themselves or to avoid frequent channel adjustment (this may cause intermittent service interruption).
If an AP needs radio calibration, automatic channel selection must be enabled.
When automatic channel selection is enabled, the manually configured channels do not take effect to ensure that the radio works in the optimal channel environment.
