To configure auto DFS:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
3. Enable auto DFS.
dot11a calibrate-channel self-decisive
By default, auto DFS is disabled.
dot11bg calibrate-channel self-decisive
4. Specify the calibration
interval.
dot11a calibration-interval minutes
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.
To configure one-time DFS:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
3. Enable dynamic channel
selection.
dot11a calibrate-channel Optional.
By default, auto DFS is disabled.
dot11bg calibrate-channel
4. Configure one-time DFS.
dot11a calibrate-channel pronto ap
{ all | name apname radio radionum } Optional.
Not configured by default. dot11bg calibrate-channel pronto ap
{ all | name apname radio radionum }
5. Specify the calibration
interval.
dot11a calibration-interval minutes Optional.
By default, the calibration interval
is 8 minutes.
dot11bg calibration-interval minutes
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.
To set DFS trigger parameters:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
