Figure 179 Setting channel calibration
NOTE:
When an AP uses the radio whose working channel is auto to establish a WDS link, the auto Dynamic
Channel Select (DFS) function of the radio automatically takes effect. Auto DFS of the radio is
automatically performed at a calibration interval when the channel quality becomes poor to reach the
channel switching condition, and the radio selects a non-radar channel with the best signal quality as its
new working channel from the available channels. When a radio selects a new working channel, DFS
happens, and the channel switching information is displayed on the Channel Switch Info tab. A radio can
save three latest channel switching records at most.
