Energy Efficiency Tunable

[spetrillo]

I was reading the pinned document on IPS performance and it mentions an energy efficiency tunable to use. I have added it to the tunables but its coming back as unsupported in the Type column. Is this option no longer used or needed?

You need to pick the right tunable. It depends on the driver used by your NIC

As mentioned earlier, your Network interface must support energy efficient ethernet.

EEE is something you don't really need unless you have a switch which is providing power over ethernet to 20+ APs and switch itself is power hungry as heck.

Downside of EEE is that it can slow down connections and even cut them outright if not properly setup.

Benefit of EEE is in lowering your electric bill and keeping your switches cool by lowering their power consumption based on how many clients connected to them require full network speed or how much power APs need thru PoE ports.

In other words EEE is method which is used to automatically determine how much power your network REALLY needs instead of letting everything run at max power consumption levels
