3.
Enable auto DFS.
dot11a calibrate-channel self-decisive
By default, auto DFS is disabled.

By default, the calibration interval
is 8 minutes.
dot11bg calibration-interval minutes
Configuring one-time DFS
With one-time DFS configured for an AP, the AC performs DFS when the working channel of the AP meets
a trigger condition, and informs the adjusted channel to the AP after a calibration interval (defaults to
eight minutes, specified with the dot11a/dot11bg calibration-interval command). Then, if you want the
AC to perform DFS for the AP, you have to make this configuration again.

Configuring DFS trigger parameters
The CRC error threshold, interference threshold, and tolerance level determine DFS.
The system begins to calculate the channel quality when either the CRC error threshold or interference
threshold is exceeded on the current channel. However, the new channel is not applied until the quality
of the current channel is worse than that of the new channel by the tolerance threshold.
