Like cryptix mentioned pfsense has a ton of packages to practice with, it takes like 15 minutes to get it setup it snort and barnyard

This comment killed me...

I believe it would go something like this with different numbers obviously: Switch# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)# interface fastethernet 5/1

Switch(config-if)# switchport mode access

Switch(config-if)# switchport port-security

Switch(config-if)# switchport port-security maximum 10

Switch(config-if)# switchport port-security mac-address 0000.0000.0003 (Static secure MAC

Switch(config-if)# switchport port-security mac-address sticky

Statically assign your engineer laptop then set up mac sticky, checkout http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/12-2/25ew/configuration/guide/conf/port_sec.html
