I usually find it easier to ping another system, swapping cables until it
works.  Once they're up in a particular sequence they won't change until
something else in the hardware changes.

Once you have them identified, marking with a Sharpe pen may help for the
next time you unplug the cables and forget which was which.

Some NIC drivers will turn the link light off when the driver's down so
doing an ``ifdown eth0'', the seeing which lights are still on may also
work.
