The FL-4320-BOOST-K9 is a software license that unlocks the full throughput capacity of Cisco 4320 Series routers, enabling data rates up to 50 Mbps.
The FL-4320-BOOST-K9 license is compatible with all Cisco 4321, 4322 and 4324 models in the 4320 Series running IOS XE 16.12 or later.
Install the license via the Cisco IOS XE CLI by importing the .lic file, then activate it with the `license boot module c4320 throughput boost` command.
The license raises maximum throughput from 20 Mbps to 50 Mbps, delivering a 2.5× performance boost for high-demand environments.
Yes, the router must run Cisco IOS XE 16.12 or newer and have an active Cisco Smart Licensing reservation.
Yes, you can disable the boost license at any time using the CLI command `no license boot module c4320 throughput boost`.
Licenses are delivered as digital entitlement certificates via Cisco Smart Software Manager with a license key for activation.
You can choose perpetual licensing or a 1-, 3-, or 5-year subscription, tailored to your budgeting and deployment needs.
Subscription licenses include software updates and 24×7 TAC support for the duration of the term; perpetual licenses require a Smart Net contract.
No, enabling the boost license only adjusts the throughput limit and does not modify your current routing or security configurations.
Use the CLI command `show license status` to confirm that the throughput boost feature is listed as active on your device.
Yes, you can convert a trial license to a full FL-4320-BOOST-K9 license by importing the permanent entitlement key and activating it.
No additional hardware is required; the license leverages the router’s existing CPU and forwarding engine capabilities.
Digital licenses are non-refundable once provisioned, but you can contact Cisco support for special circumstances within 30 days of purchase.
By raising throughput capacity, the license allows higher encrypted VPN tunnel bandwidth, reducing latency and improving user experience.
You can buy directly from Cisco Partners or through the Cisco Commerce Workspace, where you’ll receive the entitlement key electronically.
