I am not sure I understand your question but if you are asking if you can connect an AP to the admin interface of a controller the answer is NO the admin interface is for Management only. You must create a Physical interface on the controller and ap-registration on that interface.

the Problem is:

If the AP's are in a remote subnet made sure controller has its default route populated.

Hello Baha,

I can't see a problem. In your screenshot we can see three APs working (the green one) and two APs are not working (not connected or down).

But what are you asking for?

We can only help you if you describe your problem in detail.

Best regards
Stephan

The problem is that the AP03 and AP04 do not connect and 
if I send a ping if they answer 
I can not activate them

Ok,

as you screenshot shows your APs connected you controller in the past. So what changed since the last successful contact?
  • IPs
  • Location
  • Network
  • VLAN
  • ...
?

Or did you add your APs manually (by adding the MAC address manually?)

Yes I add APs manually

You should never do that! Let them show up on their own and then and only then do you know the device has made it to the controller. Delete any added manually.

How do I make the connection?

It is useful to search and read "Discovery and Registration" in you controller online help.

Ok, what function do you use for controller discovery? DNS-Entry, DHCP-Option?

Sorry but please confirm - are you able to ping the AP or not.
From which device do you ping from = is it the controller or a PC in the same subnet.

First we need to make sure that you are able to communicate from AP to controller.

if you ping
 
from a PC in the same subnet.

Ok,

than you can use one of the discovery processes I described above.
The fast one is the way via ssh to the AP link one.

HI All, 

back again with some findings and details for you.

the AP was set back to factory setting to enable a proper start
Controller static IP was set on the AP -- 10.100.10.70/24
AP static IP was set -- 10.100.10.78/24
DHCP disabled
all applied and saved and afterwards rebooted

now on the Identifi wireless solution there is no way to "auto" discover AP
Options like DNS or DHCP do not apply to the existing environment as previous colleagues did not used such config (unfortunately no documentation available) as all other AP's have fix ip's and in the DNS environment no Domain is visible.

checked on on-line help, several manuals but with no success

observations:
AP can be pinged from PC but cannot be reached via Controller
all other AP's are connected to the same Core Switch using the same config on all ports (basically a copy) 
on the Controller GUI no VLAN id is specified for the existing AP's, although the Controller has VLAN 110 specified in the general setup config
The AP is only used with PoE not with a Power Supply.
In the Controller I see that a Pair Controller with an Ip 10.100.10.202 is used (there is no second controller) but if try to delete it warns me that all foreign Ap's will be lost, not sure if I can go ahead and save as I cannot take the risk to loose the already connected AP's.

hope this helps

You'd delete the paired controller if you've only this one - as per the screenshot all APs are local = there are no foreign APs.

now on the Identifi wireless solution there is no way to "auto" discover AP
If the AP is in the same subnet/VLAN as the controller interface (that is enabled for AP registration) the AP is able to discover the controller.

I'd enable DHCP (with a small scope - IP range that isn't used by the active APs) on the controller topology and then factory reset the AP again.
The AP should get the IP from the controller and should be able to connect.

for some reason no discovery at all, DHCP cannot be enabled in the Controller, following the online help the menu is different and does not allow any DHCP config.

Hello baha,

your wrote "AP can be pinged from PC but cannot be reached via Controller".
Do I understand correct you can ping you AP from the PC but not from the Controller?

Please do a SSH session to the AP and ping your default GW and your controller from the AP.

Best regards
Stephan

yes indeed can ping from PC, and not from controller.
connecting via SSH GW is reachable but not the controller.

doing the same on other AP gives me ping on both GW and Controller.

is there something missed on the Ports?

It sounds like the controllers default route is not populated.

You can surely switch to static config after your AP uses DHCP to find the controller the thing you need to remember is you must also configure the wireless search list so the AP will have the controllers IP at all times. Keeping in mind if you cset factory the AP it will never find its way back. Better to do static reservations in DHCP server.

Hi All,

thanks a lot to all of you for the great support.
After doing a re-config at Port level we are able to see the AP with the static IP.
Seems to work for now!
