did a first cisco 101 today 3rd of Nov 2011
The LantronixEts32pr devices are helpfull to communicate with multiple serial devices (eg. cisco devices).

[edit] packet tracer
cisco has a simulation tool called packet tracer; it's great for experimenting with configs, but there's some strange quirks (eg. Just changing IP-addresses got me from a non-working situation to a working setup: 10.1.1.1/24 to 10.1.4.1/24)
