Cisco ISR 4000 Licenits FL-4220-BOOST-K9

The Cisco FL-4220-BOOST-K9 is a Performance Boost software license designed for the ISR 4221 router within the Cisco ISR 4000 series. It unlocks the platform maximum processing capacity by removing the default throughput limitation, delivering higher aggregate bandwidth across all chassis interfaces. Natively compatible with IOS-XE, it is activated through the Cisco Smart Licensing portal without any hardware replacement.

This license is intended for network teams looking to optimize an already-deployed ISR 4221 at a branch or fast-growing remote site, without investing in a new router. It is the ideal solution when application traffic has increased since the initial installation. Genuine Cisco license, immediately activatable via Smart Account.
