	You don't need to implement it.  It's implemented at the switch for you.

	Not the way we did it with RadWARE WSD Pro+ switches.  You just 
set up an IP alias on the loopback interface matching the virtual IP 
address that is configured on the switch for the service that you are 
supporting, and the server pretty much magically does the rest.
