DFS Channels - Advertised H Enabled etc

Maybe i'm doing something wrong, however, enabling all dfs channels and channel groups, I only see Ap's using channel very few of the DFS channels in the DFS range.  All AP 205 and a few AP 275's...  Thoughts, suggestions?

Re: DFS Channels - Advertised H Enabled etc

How many access points?
What channel width are you using?
It takes a great deal of time to scan extra channels to assign them. For an AP to use dfs channels it cannot be just a little better...it must be a certain margin better than the channel that it is currently on.

If the ap is happy with its current channel, there is no reason to choose a dfsmall channel.

Re: DFS Channels - Advertised H Enabled etc

Understood... i had anticipated a channel seperating similar to arm and standard 5Ghz selection.  If i can see an AP on 1 dfs channel I can confirm its working.  Thanks
