the default on Cisco switches is to wait 30 seconds before fully enabling
the port so that it can listen for spanning tree broadcasts.

for windows systems this doesn't cause any problems (they take long enough
to boot), but for a tightly configured linux box it can be fully booted
long before the switch decides to enable the port (for that matter, I have
a bare-metal install process that takes about 90 seconds from hitting
power, from a CD. I could probably speed things up by switching to USB
boot media)
