just to make sure that I didn't misunderstood.... ;)
Beginning with FortiOS 6.4.2 there is the possibility to modify the arrp-profile in a more granular manner.
In the (only possible) default profile dfs and weather channels will not be included in an arrp run as far as I understood....
It surely looks like it when I take a look at the channel assignments in larger environments... Only UN-II-1 Channels on the 5 GHz DARRP Radios.
Can someone confirm that?
e.g. "set include-dfs-channels / weather-channels enable" has to be set to take dfs channels into account?
