 = IV !OpenFlow Switching = #IV
+This section goes over the !OpenFlow aspects of the switch.  
+== 4.1 What is !OpenFlow? == #intro
+!OpenFlow is a virtualization technology developed by Stanford. Ideally, it allows administrators and researchers to configure the switch's behavior freely, without constraints of TCP/IP or the native firmware. This is achieved by removing traffic switching decisions off of the switch and onto an external, highly configurable controller. More on !OpenFlow can be found at http://www.openflowswitch.org.  
+
+The switch supports !OpenFlow in the form of virtual switches, or "datapaths" that overlay VLAN configurations; Each separate VLAN residing on the same device can be instantiated as a virtual switch that can be controlled by separate controllers and/or scripts, or be kept as a traditional VLAN that does commodity switching.       
+
+== 4.2 Outline == #outline
+In order to make the switch !OpenFlow capable, you need to flash the switch with an SD card containing specialized firmware. The rough outline of the steps are the following:
  
-== 4.1 What is !OpenFlow? == #intro
-== 4.2 Preparation == #prep
-Materials 
-disable STP
-vlan, port configs 
-== 4.3 Flashing the switch == #flash
+ 1. disable Spanning Tree (STP) 
+ 1. configure VLANs and ports, telnet
+ 1. copy firmware and license to SD card
+ 1. add openflow.conf to SD card
+ 1. reboot switch with SD card
+ 1. configure virtual switches  
+
+Since it is easier to describe using examples, this process will be described using the steps involved in configuring [http://orbit-lab.org/wiki/Internal/OpenFlow/OrbitSwitches/sw-sb-combined sw-sb-01], one of the aggregate Sand Box switches currently running in !OpenFlow mode. 
+
+== 4.3 Configuring the switch == #ofconf
+This section corresponds to steps 1 and 2 in the Outline. Because virtual switches are based on VLANs, all port and VLAn configs should be done before flashing. This part of the setup is just normal configuration using `vlan`, `interface vlan`, and `interface gigabitethernet` contexts.
