I'am trying to install an FL-4320-PERF-K9 (Performance) License on an ISR4321 to increase throughput from 85 mbit to 100 mbit but it tells me that there is a better license installed already.. Does anyone know what that is and how i can see that? Log messages clearly describes that it is using the maximum bandwith of 85 mbit for this license platform…
%CERM_DP-4-DP_TX_BW_LIMIT: Maximum Tx Bandwidth limit of 85000 Kbps reached for Crypto functionality with securityk9 technology package license.

If throughput (performance) license is enabled as it is shown on the attached picture, your throughput is 100mbps. Using a 4321 you have 2 options. 50mbps without performance license, and 100mbps with it.
