Level 3 Switching (Bandwidth Limiting) on the Green Interface

[Guest]

We have a problem that I hope I can address with the Endian box.

We have a device on our LAN that periodically slams our internet connection. I need to figure out how to bandwidth limit it and preferably still keep it on our 'green' network for other functionality.

I cannot modify the device to be less hogging.
Level 2 port speed settings will not work - I need to throttle the bandwidth beyond just 10/100 (I'd like to set it to 20D/5U)
QoS will not work - this device does not play well with QoS.

What I would like to do is to add a 3rd NIC to my Endian box, assign it to the GREEN interface, thus I will have 2 green interfaces and effectively a 2-port switch. It seems like Endian supports this part without a problem. The trick is that I want to bandwidth-limit one of those green interfaces, while leaving the other one on the unlimited - this will ensure a minimum internet pipe space for the unlimited port.

The Endian does L3 functions, there has to be a CLI or SSH method of doing this - maybe loading some module into the core Linux load?
