As you have a 105 and 205 AP, they run a different hardware architecture and only cluster if the version is the same. If firmware mismatches, the new AP will not join, exactly what you describe.
Further, on the close proximity, performance will be poor if you place APs close to eachother. As a rule of thumb, make sure the APs are separated more than 3m/10ft from other APs or transmitters (like indoor cellular, DECT, or picocell stations). But the AP should come up, just performance is below what you could expect.

Are they each one assigned statically as their own Virtual controller with different name? Do you see the other IAP in the WebUI from the one that is "working"?
One thing I would test is to enable the Extended SSID in System > General > Show Advanced Option. This option is to enable from 8 to 16 SSID but I had issue in the past when this option is not enable, an IAP would keep connectivity to the cluster via a hidden wireless link when isolated between 2 switches or 2 network. Might be worth trying!
...start working. If i plug in my cable on the other switch, the other ap will start working too....
Yes they have the same controller IP and, when they are attached on the same switch, if i go on the IP of the non working IAP, i am redirected on the IP of the working IAP.
Another thing that i have just discovered: when they are on different switch, to make them emit wifi,it seems that i need to connect my PC with the etherneth cable to make them work.
So: if im not plugged in with my cable, they will not work. If i plug in my cable on a switch, the ap on that switch will start working. If i plug in my cable on the other switch, the other ap will start working too....

Hi and thanks everybody for the replies.
The problem is solved.
I have used two IAP 205 ( Aruba, same FW version, same FW release ).
With the command "allowed-ap mac:address:of:the:other:ap" inside the two IAP ( telnet ). AP 1 must have the AP 2 mac address allowed and vice versa.
Now they are able to join the same cluster ( one became "master"/"controller" and the other "slave" ). I can clearly see the join if i go on the virtual controller IP: i see two IAP.
I will test if two different models can work together if they have the same Firmware Release.
I hope that this post will help people for future problems. Thanks all.

Very few bridge deployments involve 32 APs that are within earshot of each other.
For those 32 APs, application sessions are transferred from AP to ap as the user roams. For the 33rd, ap the device can roam, but the application sessions will not be transferred.

One Further question, I currently have CPSec disabled. I've noted in the documentation that it Doubles the boot times of the APs when it is enabled. Are there any other significant drawbacks to having it turned on?
The reason I ask is, I'm really considering bridge mode for the wired ports on the 93H. I currently have everything working in tunneled mode but would like to move the wired ports to bridge and leave the wireless in tunnel mode. We have a lot of Streaming DVD players and other device connected Wired in our dorms which I would rather have Bridged instead of tunneled back to the controller. This seems possible, but I haven't tested yet. Any thoughts?

I don't have the second controller but please also elaborate on other points like is there a possibility of having a backup IAP to minimize the downtime ?
If not, how much time does it takes to re-establish ? also is it a good design ?

Hi Lee, just a couple of things to add to the discussion. ClearPass can absolutely work in multi vendor networks and provide the guest registration/sponsoring and authentication services you describe. One difference though with Bluesocket is that ClearPass is not an inline device, it works out of band and uses protocols like radius and http/s to interface with the network infraestructure. So aside from bandwidth quotas, ClearPass itself does not do firewall policies or rate limiting of traffic.
You can however configure specific role based policies on ClearPass that will trigger enforcement actions on a NAS device such as your cisco WLC (same is true for Cisco switches). You can send back radius attributes and dACLs to enforce basic firewall and QoS policies. You can also configure ClearPass to send upstream messages to your internet firewall and provide a deeper layer 7 enforcement. Given you are talking maily about guest access, you can probably just plumb the guest VLAN through a specific firewall zone and policy although I would need to better understand the types of roles and FW policies currently in use on your Bluesocket boxes.
One other thing to note, ClearPass can also interface with your Bluesocket environment if you want to retain its inline firewalling capabilities. You could centralize all of the actual guest sponsoring, device registration and guest authentication with ClearPass and just use the Bluesocket boxes to enforce firewall and network policies as they are today. This is a known use case that we have working at other locations around the world and may be an interesting option for you.
We can have one of our ClearPass technical specialists reach out to you to discuss further if thats of interest. Also happy to answer any other questions on this forum
A good chunk of the CPG customer base uses the product with other vendors.
Take a look at the Clearpass solution, http://www.arubanetworks.com/products/clearpass/
It is very feature rich and will probably meet all of your needs and more. It integrates with Cisco and many other vendors.

- Hope that most of your clients support 5ghz.
- Hope that most of your clients support DFS channels
- Deploy DFS channels and make the 5ghz 6db stronger than the 2.4ghz band.
Honestly, "seeing" 100 other networks is not really a dealbreaker. RF can travel hundreds of feet, especially in the 2.4ghz, so they can be observed with laptops, but less with mobile devices. If clients are actively connecting to those foreign networks AND sending data AND YOUR clients can see the traffic, that is what could be problematic. Most likely you can see these networks because the access points are powerful, but the clients might not be powerful enough to create more cochannel interference for you.
If these are 5ghz networks, the cochannel interference from these networks is less of a problem, because it does not propagate as far as the 2.4ghz band. This gives you an opportunity to deploy on 5ghz to support your clients.
If these are instant APs, you would want to keep an eye on the RF utilization on any channels that you choose to deploy on by looking at the front page. On controller-based access points, the dashboard will also give you an idea of what the RF utilization is on any access points you choose to deploy.

In an Aruba Controller-based system, the access points themselves do not offer much information or even answer to SNMP reads, so an external system would not be able to tell if they were "up" by pinging them. Access points can have ip addresses and answer to pings but they would not necessarily be up or even connected to a controller.
It is probably far easier to look at SNMP traps from the controller itself to see if an access points goes down or not. You can also use SNMP on the controller's ip address to see what APS exist, etc. A record of access points up and down ip address are kept by the controller.
