The Cisco 5508 Wireless Controller (AIR-CT5508-K9) is an enterprise-class WLAN controller designed for medium to large-scale deployments. Supporting up to 500 access points, it delivers centralized RF management, seamless Layer 2/Layer 3 roaming, high-availability clustering, and enterprise-grade WLAN security across campus networks.

AP capacity is expanded through adder licenses — simple right-to-use (RTU) licenses that unlock additional access point support. Unlike newer Cisco controllers that require Smart Licensing, the 5508 uses perpetual RTU licenses: no Smart Account, no CSSM registration, no annual renewal. Mix and match adder sizes to reach your exact AP count, up to the 500 AP maximum.

Frequently Asked Questions — 5508 Controller Licensing

What is the Cisco 5508 Wireless Controller licensing model?

The Cisco 5508 Wireless Controller uses a right-to-use (RTU) adder license model. The base controller (AIR-CT5508-K9) includes a default number of supported APs, and you purchase adder licenses to incrementally expand capacity up to 500 access points. Licenses are perpetual — pay once, use forever. No Smart Account, no CSSM registration, and no annual renewal required. This is a major advantage over newer Cisco controllers that mandate Smart Licensing subscriptions.

How many APs does the base Cisco 5508 controller support without adders?

The Cisco 5508 Wireless Controller typically ships with 12 AP licenses included by default (verify your specific unit — some SKUs may differ). Each adder license (5, 25, 50, 100, or 250 APs) is cumulative and adds to the activated capacity. The maximum supported is 500 APs per controller. You can mix and match adder licenses — for example, two 250-AP adders = 500 APs total (fully loaded controller).

How do I install an AP adder license on the 5508 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/L-LIC-CT5508-XXA.lic.
  2. GUI method: Navigate to Management → Software Activation → License, click "Install License", and upload the file.

The new AP capacity becomes available immediately — no controller reboot required. Verify with show license summary (CLI) or under the License page in the GUI.

Are 5508 adder licenses transferable between controllers?

No. Like all Cisco RTU licenses, 5508 adder licenses are controller-specific — each .lic file is bound to the controller's unique device identifier (UDI). If you replace your 5508 controller (RMA, hardware failure, or upgrade), you will need new licenses issued against the replacement controller's UDI. Always provide the output of show license udi from the correct controller when ordering.

How quickly will I receive my 5508 license after purchase?

Most 5508 AP adder licenses are delivered within 2–12 hours of order confirmation and UDI submission. Provide the output of show license udi from your controller. The license file (.lic) is sent by email — upload via GUI or CLI for immediate activation. If you need expedited delivery, contact us before ordering.
