wlan dfs multi-radar-detection

Description
When an access point detects a radar signal it distributes this information to all access points
that it reaches directly via Ethernet.. If at least one further access point verifies the radar signal
within 40 ms, all connected access points are informed. All the devices sending on this channel
change to a different channel. The channel is blocked for 30 minutes for the access points in
the network.
If no fixed channel is defined for the access points, the function cannot be used reliably. In this
case the verification of the radar signals is only possible when at least two connected access
points happen to transmit on the same channel. If only one access point detects a signal on
a channel, it treats this as a valid radar signal.
Requirement
● DFS is enabled.
● You have a system with several access points.
● The access points are connected together via an Ethernet network.
● The access points send on the same channel.
● The access point does not select the channel automatically.
● You are in the Interface Configuration mode of the WLAN interface.
The command prompt is as follows:
cli (config-if-wlan-0-X)#
Syntax
Call the command without parameter assignment:
wlan dfs multi-radar-detection
Result
The function is enabled.
Further notes
You display the setting with the show wlan advanced <wlan 0/X> command.
You disable the function with the no wlan dfs multi-radar-detection command
(default setting).
