Configuring mesh DFS
NOTE:
Before configuring mesh DFS, make sure the AC uses the auto mode (configured by using the channel
auto command); otherwise DFS does not work.
Configuring automatic mesh DFS
With mesh auto DFS enabled, an AC performs DFS when the working channel of an AP meets a trigger
condition and informs the adjusted channel to the AP after a calibration interval. After that, the AC will
make DFS decisions at the calibration interval automatically.
To configure mesh auto DFS:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter WLAN RRM view. wlan rrm N/A
3. Enable mesh auto DFS. mesh calibrate-channel self-decisive By default, auto DFS is disabled.
4. Specify the calibration
interval. • dot11a calibration-interval minutes
• dot11bg calibration-interval minutes
Optional.
By default, the calibration interval
is 8 minutes.
Configuring one-time mesh DFS
With one-time mesh 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. Then,
if you want the AC to perform DFS for the AP, you have to make this configuration again.
To configure one-time mesh DFS:
