Key Features
The LIC-CT3504-UPG is a crucial upgrade SKU for the Cisco 3504 Wireless Controller, serving as the top-level identifier for adding Access Point (AP) licenses. It facilitates network scalability by allowing more APs to connect to the controller, which supports up to 150 APs. While the specific addition is often made via a part like LIC-CT3504-1A, the -UPG SKU is necessary for configuration and Smartnet contracts.
