Actually, I have the Extreme x450e in my local network.
I want to put the mac address filter system for limit the number of machines to connet in my LAN.
After several research, I realize that some functionalities are absent.
Specially, the "MAC lockdown" command .
So I suppose that I don't have the recent version of the firmware.
Actually, I have the 188.8.131.52 version .
So, if you suppose that i have a old firmawre, can you tell me the last version of the OS please ?
