Frequently Asked Questions — 2504 Controller Licensing

What is the Cisco 2504 Wireless Controller licensing model?

The Cisco 2504 Wireless Controller uses a right-to-use (RTU) adder license model. The base controller (AIR-CT2504-K9) ships with a default number of supported APs, and you purchase adder licenses to incrementally expand capacity up to the maximum of 75 access points. Licenses are perpetual — pay once, use forever. No Smart Account, no CSSM registration, and no annual renewal fees.

How many APs does the base Cisco 2504 controller support without adders?

The Cisco 2504 Wireless Controller typically ships with 5 AP licenses included by default (check your specific unit — some SKUs may include different base counts). Each adder license (1, 5, or 25 APs) is cumulative and adds to whatever capacity is already activated. The maximum supported is 75 APs total per controller. You can mix and match adder licenses — for example, two 25-AP adders + one 5-AP adder + the base 5 APs = 60 APs.

How do I install an AP adder license on the 2504 controller?

Installation is straightforward via the controller's web GUI or CLI:

  1. CLI method: Transfer the .lic file to the controller via TFTP/FTP, then run license install tftp://server/path/L-LIC-CT2504-XXA.lic.
  2. GUI method: Navigate to Management → Software Activation → License, click "Install License", and upload the file.

The new AP capacity is available immediately — no reboot required. You can verify the license count with show license summary (CLI) or under the License page in the GUI.

Are 2504 adder licenses transferable to a different controller?

No. Cisco 2504 adder licenses are controller-specific — each license file (.lic) is tied to the controller's unique device identifier (UDI). If you replace your 2504 controller (e.g., RMA or hardware upgrade), you will need new licenses issued against the replacement controller's UDI. This is standard for all Cisco RTU licenses. When ordering, always provide the output of show license udi from the correct controller.

How quickly will I receive my 2504 license after purchase?

Most 2504 AP adder licenses are delivered within 2–12 hours of order confirmation and UDI submission. All you need to provide is the output of show license udi from your controller. The license file (.lic) is sent by email — upload it via GUI or CLI for immediate activation. If you need expedited delivery, contact us before ordering.
