If an access point detects radar on a channel, it needs to vacate it immediately. With that being said, there are false positives that are more prevalent when running wider channels.

Nice. Looks like it was radar detection. I kind of had a feeling that might be it. I live a few miles from our local airport, and under a flight path - I'm guessing this is what this is.
So does that mean radar detection trumps manual settings ? I guess it makes sense as to stay on the right side of the "law" with regard to RF.

Try "show ap arm history" on the commandline.

Man, I'm really struggling here. I had it set to 100E - and all of a sudden it changed itself to 52E again. Could this be a bug ? Is there some setting I'm missing to completely manually configure channels ?

Thanks for the reply. Yes after posting this I realized part of my issue was reading the channels wrong. After setting it to 100E it seems to be working as expected.

What is your regulatory domain? E = Eighty Mhz wide channels.

Hello,
First a disclaimer - I'm new to Aruba. So many of the nuances (ex: vs. Cisco) I'm still learning...
I have an AP515 running virtual controller. Just one AP right now. I'm running 8.6.0.15.
I can't seem to get my manual channel selection to "stick". I have gone into the AP config, and changed from ARM to manual. I'm running 80MHZ on 5ghz - so I have all that set up correctly. From what I'm seeing / understanding - that means the two relevant channels would be 36S and 100S yes ? I set the AP to this - and it's on that channel when it first boots. After a short while - it kicks over to some other channel (ex: 52E).
I also tried to customize the valid channel list - and I've only selected 36S and 100S. Once I did this, my AP went to 36E - even though I have it configured for 100S. So that seemed to have some kind of effect - but I'm still confused as to what's happening.
So my main question is - what's the magic cocktail of knobs to turn to get manual channels to stick ?
PS: what do the E and S channels mean ? E = 40mhz, S = 80mhz ? I can't seem to find a table detailing these.
Thanks in advance.
