Hello Jonathan,

Here is the official documentation of BL460c Gen9 https://www.hpe.com/psnow/doc/c04380273.html?jumpid=in_lit-psnow-red

In the chapter "Technical specification", you can find: HPE FlexFabric 20Gb 2-port 650FLB FlexibleLOM

Maybe it's KR4 instead of KX4, let you decide.

Is it what you need ?

Can we add the 400G as well, I'm looking at deploying some of these NIC's for our Snake Test Traffic Generators running iperf :)

You want us to add an interface type to NetBox, but you're not sure what it's called? Please do some more research to determine exactly what it is you want to add.
