I've seen this request from others as well. Do you have any 
proposal/preference to limit the data rate from the switch?

I'm aware of these products; we (AimValley) build and sell several 
similar products as well. Since I'm a systems architect, and not a sales 
person, my email was mostly meant to get an idea of what type of smart 
SFP products people in the field would like to see come to light, and 
what type of features they should have. I'll then try to build a 
business case to get the product developed. MACsec is currently on the 
top of my own list, but I'll gladly pass other ideas to my colleagues.

Kind regards,
