A question for you my most esteemed colleagues.

I have an older 3200XM controller (that is up to date AOS wise) that I have turned into a VPN concentrator. It is in Master mode and is working great in that capacity which makes me happy. However I have two AP93s that like to ditch their controller and start reporting back to this old 3200. I have verified that the LMS IP address is correct in the AP System profile that the APs in question belong to. So the question is, how do I keep these to wayward APs from migrating back to this old 3200 with out manually setting the controller IP in the individual AP provisioning profile?

As always, thanks for any input!

Are the AP93s configured as remote APs?

Negative ghost rider, standard APs like the rest in that group.

Can you tell us how those APs are provisioned, and what method they use to discover their master on bootup?

They are provisioned via standard ADP methods (now with DHCP as I no longer assign statics to APs) with the AP groups dictating what controller they report to through the LMS IP setting. Is there a way to disable ADP on the VPN controller?

Detail is important here.  Which method?  If the AP is in the same subnet as the VPN controller it will discover it through broadcasts before it looks at DNS or DHCP options.  You can either:

(1) Disable ADP Discovery and joins on the VPN controller  http://www.arubanetworks.com/techdocs/ArubaOS_64x_WebHelp/Web_Help_Index.htm#ArubaFrameStyles/1CommandList/adp.htm

(2) Statically point the AP93 to the controller that it needs to be on.

Ahhh ha! yes, I'll take option 1 for 500 please Alex!!!

Thanks again CJ, I greatly appreciate your assistance!
