Activating Cisco WLC 3504 AP License

Cisco has announced the End-of-Life (EoL) for the Cisco WLC 2504 this year so we're getting the new Cisco 3504 wireless controller. Below are photos of the WLC 3504 and this is a helpful link for the information on chassis ports and LEDs



I had to troubleshoot a brand new WLC 3504 and for some reason the 1852 AP wasn't able to join the wireless controller even though the country (for the AP) and date/time were correctly configured. The logs showed a looping CAPWAP State: DTLS Teardown error when consoled to one of the AP.

There were no APs that have joined the WLC per checking on the Monitor dashboard and under Wireless > Access Points.



In order for the APs to join the WLC, you'll need to activate the ap_count license. Go to Management > Software Activation > Licenses > click ap_count (hyperlink).


Set the License Status to Activate (default) > click Set Status.


An End User License Agreement (EULA) page will pop-up. Click I Accept.


The APs started to join afterwards. The box comes with the AP Adder License (or Entitlement). You'll need to specify the AP count under MANAGEMENT > Software Activation > Licenses > License Count > Add > type a number > Set Count. You'll be prompted again to accept the EULA.


For this scenario, I ordered a WLC 3504 with 15 AP license.




The Permanent AP Count (Adder) license will appear afterwards.
