DFS-Rescan-Num-Channels

This parameter specifies the minimum number of free channels that a DFS scan is required to find.

With the default value of 2 the AP continues to run a DFS scan until 2 free channels are available. If the AP recognizes an active radar pattern during subsequent operations, at least one other free channel is available for the AP to switch to directly.

Note: If a high number of channels is specified, the initial DFS scan has to examine a large number of channels. Scanning takes 60 seconds per channel. In this context please observe the information given under 2.23.20.8.15 DFS Rescan Hours.
