@nsmwella Licensing has changed multiple times over the last few versions of IOS-XE and differs across different hardware platforms so you need to be absolutely specific about what hardware platform you are dealing with and what version of IOS-XE you are using. There are detailed licensing guides for each platform.
Bandwidth/throughput is usually configured separately from the license boot level and the license boot level will determine what throughput levels can be configured so sometimes you'll need to reconfigure the license, then reload, then change the throughput and reload (because higher throughputs cannot be configured until the right license is configured). Throughput is usually configured with commands like:
platform hardware throughput level 2000000
platform hardware throughput crypto 2.5G
For example for 8200/8300/8500 platforms see: https://www.cisco.com/c/en/us/td/docs/routers/cloud_edge/configure-licenses-throughput-catalyst-8000-platforms.html#tier-and-numeric-throughput-mapping for a summary of the combinations and not the changes between different versions of IOS-XE.
Cisco have made these licensing requirements EXTREMELY complicated and even the Cisco account teams struggle to understand them - often having to refer to the BU for clarification. Also not always documented anywhere in these licensing guides - some features require the highest available Advanced tier license regardless of bandwidth requirement - again this needs to be clarified by your account team with the BU.
