Cisco ISR 4000 Licenits FL-4220-PERF-K9=

The Cisco FL-4220-PERF-K9= is a performance license for the ISR 4221 router in the Cisco ISR 4000 series. It removes the default software throughput limitation applied to the platform, allowing the ISR 4221 to reach its maximum packet processing capacity. Activation is entirely software-based and performed through the Cisco Smart Licensing portal, with no physical intervention on the device.

Recommended for small sites or branch offices whose bandwidth requirements have grown without justifying a router replacement, the FL-4220-PERF-K9= maximizes the useful lifespan of the deployed ISR 4221. It is well suited to retail, SMB, or IoT environments with increasing application traffic. Genuine Cisco license, manufacturer warranty.
