After upgrade,enable calibration bandwidth function, it is enable by default. With this way, after the AP detect radar signal, it will switch to other random channel

auto-balance: applicable to most wireless scenarios
high-stability: applicable to scenarios with continuous interference.
high-throughput: applicable to scenarios with good wireless signals and non-continuous interference.

Checking the channel switch of the AP, it shows that the switch reason is dfs, it means that the AP detect radar and after that the channel switch. It is normal that the AP switch channel when it detect radar signal. Current software version of the switch is S5720 V200R010C00SPC600 and it doesn't support radar channel choose and channel switch back, so after channel change to low channel, before next calibration, the AP will keep on low channel.

thanks for sharing!

can you detail for below?

Recommend upgrade software of the switch to V200R011C10SPC600 and install patch V200R011SPH005. After upgrade,enable calibration bandwidth function, it is enable by default. With this way, after the AP detect radar signal, it will switch to other random channel, if the channel is low channel, the AC will enable calibrate bandwidth and change to high frequency channel.

Great example ， after did this , i am also solve one issue .Recommend upgrade software of the switch to V200R011C10SPC600 and install patch V200R011SPH005. After upgrade, enable calibration bandwidth function, it is enable by default. With this way, after the AP detect radar signal, it will switch to other random channel, if the channel is low channel, the AC will enable calibrate bandwidth and change to high frequency channel.
