How to configure a VLAN

You need a RJ45 -> DB9 (serial port) cable. You connect it to the serial port of your computer. Then use HyperTerminal (on windows). Default port settings are:
baud: 9600
data: 8
parity: none
stop: 1
flow: none
Hit Enter after setting up HyperTerminal. That will get you into the command line.
