IAP vs AP

Hi,

 

I want to clarify some question marks on my head and I think the best place for this is here. Is it true that if I want to create a controllerless environment I need InstantOS capable APs to use, for example IAP-303?

 

Then lets say I want those IAP-303 to join into a cluster. Should I convert those to AP-303 with an arubaOS version installed on it?

 

So this scenario typically looks like this: lets say I have an environment only with AP-315 and of course there is a virtual controller on it! So if I want those IAP-303 to join on my cluster, I should first check if the firmware version on those AP-315 is later than 8.3 and if it so, than I will have to uppgrade the firmware on the others IAP and by doing so they will automatically converted to APs and the firmware installed will be the same as on the AP-315 (arubaOS)!

Re: IAP vs AP

I found this article which explain a lot of different concepts (controller and controller-less), IAP and AP and a lots of important stuffs. 

 

So in controller-less mode work both IAPs and APs (instantOS and arubaOS) and they may be provisioned via Airway or Central.

Hi Fisnikm,

 

Please also look into this article:

 

https://blogs.arubanetworks.com/solutions/aruba-unified-ap-platform/

 

The main difference between IAP (Instant AP) and CAP (Campus AP) is, that the IAP is used with controllerless setups. There is no need to convert the IAP to something different when using the IAP in such a scenario. You only need to convert the IAP to CAP if you would like to use the IAP with a Controller. 

A CAP can only work with a controller, but will never be able to join an instant cluster.

Re: IAP vs AP

Hi Florian,

 

thank you for your reply. I see on the datasheet for example for AP-303 the minimum software version ArubaOS and InstantOS is 8.3.0.0 or for example for AP-315 the minimum ArubaOS version 6.5.0.0, 8.0.1.0 and InstantOS 4.3.0.0. What does that mean? Is this something related with controlling them via central, I mean those APs have to be on that particular version or above to be able to manage them via central?

Re: IAP vs AP

The datasheet is always for both modes, Instant and controller based. The minimum ArubaOS version in the datasheet is the version you need as a minimum on the controller if you would like to use those AP as a controller based AP. The InstantOS version is the minimum version, you need to run the AP in Instant Mode. 

The list of supported devices in Central can be found here:

http://help.central.arubanetworks.com/2.4.8/documentation/online_help/content/public_cloud/get_started/supported_devices.htm

 

But this has nothing to do with the software version of the device. If a device is supported in central, central supports at least the minimum software version mentioned in the datasheet.
