Wireless Access

when i use IAP , what functionalities i cannot do while i can do when using controllers ?

can i get Controler & let it manage IAP in the future ?

Yes in the future you can convert IAP to Managed APs from the controller

What funtionalities does not have 

Well i can mention you some

It does not have VPN Termination(so no via or remote AP)

It does not have the captive portal in which users you create have a time in which they will expire... on instant the users just dont expire, you have to change it manually.

It does not have advanced setting to twick like with the wireless controller.

And some other stuff...

When i get home i can tell you the others if noone else have answered you

Cheers

The IAP code is updated quickly so some of what I remember may have changed;

no RAP support / termination,

you get Device fingerprinting but no User rules,

less internal DB (vs controller),

less DHCP from the IAP (vs controller),

no routing (OSPF),

Can i apply PEF, PEFNG, or RF protect on IAP ?

IAP doesn't work like that, it has all functionality by default, it does some of the features included in the PEF license for a controller based solution and the same goes for WIP. but you don't need to add extra licenses or such.

what would be the difference between PEF and PEFNG anyway?
