Its the switch that your RaQ is plugged into.See: http://www.extremenetworks.com/products/datasheets/summit24.asp for more details.
The "100/full" almost certainly means 100mbit/s and full duplex. Not sure about that error though... thanks...
I've seen the following a few times in the last couple of weeks after I've revived my box by rebooting. Admittedly, the network is a little broadcast heavy, but it's not *that* busy. Can anyone explain what this means and (hopefully) a way to prevent the lock-ups? Raq3 @ Kernel 2.2.14C10 on an i586. Connected to an Extreme Summit/48i, auto-negotiated @ 100/full. kernel: eth0: Too much work at interrupt, status=0x4050.
