Cisco WLC AP license

I had a site that needs 10 access points (APs) but was given a Cisco WLC 2504 that only supports 5 APs by default. Cisco's website mentioned that AP license can be added in increments of 1, 5 and 25. So I availed for a 25 AP license (L-LIC-CT2504-25A) in order to accommodate the future growth of the wireless system. I followed these steps to apply the AP license.




The first step is to go to Cisco's licensing portal and register the license Product Authorization Key (PAK) that was sent via e-mail in PDF form (e-license) or hard copy.  Register the license PAK using the Product ID (PID) and serial number found in the WLC by going to Controller > Inventory. The same info can be seen using the show license udi command.




Be extra careful and double check the info that was typed in the licensing portal to avoid issues with the license not taking effect even after reboot. I've personally encountered this mistake a couple of times and had to go through Cisco TAC to re-issue a new license. TAC usually respond within a day or two.

To install the AP license, go to Management > Software Activation > Commands > Actions > Install License, and for or some strange reason only 3CDaemon works. After transferring the license via TFTP, the WLC will prompt to restart in order for the license to take effect. You can also optionally save the license.







After WLC has been rebooted, you can verify the license by going to Management > Software Activation > License. Click on the license to show more details.





Here are some useful WLC CLI commands to verify the license.
