5760 AP join

Hi there

Have a 5760 with 2600 APs'. When connecting AP's on L2 they join the contoller. Connecting AP's on different network they won't join.

Have tried with DNS/DHCP option 43 and manual controller config so pretty sure they know the controller :-)... I also see them in the controller but as NOT JOIN.

From controller

7c69.f604.c560  0000.0000.0000  AP7c69.f604.c560      10.252.3.207     Not Joined

7c69.f6bc.5b90  0000.0000.0000  AP7c69.f6bc.5b9a      10.252.3.216     Not Joined

7c95.f307.8f80  c08c.600f.0b7e  APc08c.600f.0b7e      10.252.0.205     Joined

With debug on controler i got the following:

On controller the following command is set: wireless management interface Vlan600

(the AP VLAN is 2040 for this particular location....ping is fine)

I'm a bit stucked (and almost missing the aOS CT :-))... Anyone has a suggestion or hint?

Best Regards

You didn't configure DHCP Option 43.

Hmm, I see the AP's on the controller (as NOT JOIN), so i think they know the controller (DNS configured..also static controller address)... Don't know why they keep complaining about this DHCP IP...

Option 43 also configured... only with 0A FC 00 18 type in...no option 60-vendor specific used.

Hi

It was a routing issue... AP JOIN now works....

I had the "AP Model not populated in Discovery Request. Let the AP proceed to Join & veify AP model in Join request." message today and APs were not joining when primary controller was set on the current controller, by command line on the AP via a console cable and with an Option 43 configured on DHCP. 5760s are new to our organisation, and this is my first day with them.

Googled the error message and this thread was the only result.

Routing issue was that there isn't a field to enter ip default gateway via the GUI. Entered it via command line and my APs started joining.

Hello Kasper,

What routing issue did u faced? I´ve the same issue but AP and WLC can see each other.
