It works just like most load balancers I have seen. It has knowledge of 
several protocols. You put the servers you wish to LB in a vlan, assign 
a weight, a protocol, and enable it. The weight can adjust the load 
between servers so you can send server a twice as much as server b and 
server c 3 times as much a. The protocol gives it what to check so that 
it knows when to remove one of the servers from the pool and when to 
reinstate it. You can also assign a specific command response if you 
want to test something not already integrated.
