access point can't find controller

Hello,

I have a 650 controller, one AP-115 and another AP-205. The problem is APs are not joining the controller although they see it as master controller, they pull their IPs as well from DHCP.

I have configured DHCP option 43 and 60, created DNS forward lookup zone entry and plus APs seem to be using ADP..

However APs still don't join the controller.

Here is the boot process of one access point.

Re: access point can't find controller

What version is your controller on?

What do you see in the datapath on the controller? (show datapath session table 192.168.0.10)

Do you have control-plane-security enabled?

 


If my post is helpful please give kudos, or mark as solved if it answers your post.

Re: access point can't find controller

So the 115 requires 6.3.1.0 or greater.

 

The 205 requires 6.4.1.0 or greater.

 

You should upgrade the 650 to the latest software in the GA folder and retest this if you are not at the minimum versions noted above.

Actulally data plane security was enabled and when I disabled it AP quickly joined the controller. I understand now it should stay disabled? It was enabled by default after I reset the controller though.

Thank you!

Re: access point can't find controller

It is enabled by default, but importantly the 'auto-cert-prov' parameter is disabled, which is why your APs didn't automatically join.

Good to hear you got there in the end.
