You can't have both sides of the trunk active (switch1 and switch2) from a single F5 unless you are running VSS. It’s just like configuring a port channel between a 3560 and two 6500s, spanning-tree will block one of the ports from the 6500 side. You can't properly aggregate traffic across the links of two different switches.
