The Cisco FL-4220-BOOST-K9 is a Booster Performance License specifically designed for the Cisco Integrated Services Router 4221 (ISR4221). This software-activated license removes the aggregate throughput limits imposed on the router's base configuration. While the base performance of the ISR 4221 is typically capped at 35 Mbps (upgradable to 75 Mbps with a standard Performance License), the Booster License unlocks the full forwarding potential of the hardware, allowing the device to achieve unthrottled throughput, often exceeding 1 Gbps depending on the services and features enabled. This upgrade is essential for high-demand environments requiring maximized WAN throughput, SD-WAN deployments, and intensive encrypted traffic handling without the need for hardware replacement. It is delivered as an Electronic Software Delivery (ESD) and provides a perpetual Right to Use (RTU).
