Packet based load balancing instead of connection based (default)

BIG-IP really wants to:

1- Receive a packet for my MAC

2- Look at the VLAN and L4 source/dest and match a virtual

3- Add this flow to the flow table

4- Try to connect the server-side of the flow or continue the client-handshake, depending on how the proflies are set up

All of the traffic processing hinges upon what's in the flow table, so there's not really a way to "turn it off". 

However, you can easily reconnect the server-side to a different server using "LB::reselect":

You can also reconnect the flowserver-side to a server using the "node" command if you want to disregard all BIG-IP load balancing logic:
