Parameters
channel-number: Specifies a channel by its number. The value range for this argument varies by
country code and radio mode.
auto: Configures the AP to automatically select a channel.
Usage guidelines
When radar signals are detected on the working channel of a radio, the AP changes its channel, and
switches back to the specified channel after 30 minutes. Then the AP starts the quiet timer. If no
radar signals are detected within the quiet time, the AP starts to use the channel. If radar signals are
detected within the quiet time, the AP changes its channel.
Examples
# Specify channel 6 as the working channel.
<Sysname> system-view
[Sysname] interface wlan-radio 0/1
[Sysname-WLAN-Radio0/1] channel 6
