Okay let make some things clear
You need Dell licesnse
For example
You get a Dell 651 controller
And you need dell AP licesnse...
But you CAN use Aruba APs... but you need DELLs license! to install on Dells Wireless controller
We need to have that clear...
For example
In my 650 Alcatel Controller i do have Alcatel AP license, Alcate RF Protect licesnse and Alcatel PENFG License...
But im using Aruba APS attached to it
Does this is more clear for you?
Cheers
Carlos
