Does the new iMac support Jumbo frames?

As subject. I was pretty peeved to find out my 2010 version didn't!

Cool, so the answer is 'probably'.

I'd be interested to know if anyone who has one can verify.

At least mine doesn't:

Code:

imac:~ MPE$ sudo ifconfig en0 mtu 9000
ifconfig: ioctl (set mtu): Invalid argument

Weird. My 27" 3.1GHz iMac that was delivered yesterday supports jumbo frames fine. I was quite concerned that it wouldn't because I rely on them for good performance with my NAS

I set it using System Preferences -> Ethernet -> Advanced -> Ethernet -> Configure Manually.

I've confirmed the setting by checking the output of ifconfig. It shows an mtu value of 9000.
