OK, that finally makes sense. So, we're back to where I started, with both the interface in VLAN603 blocking on each F5 and apparently no ports blocking for VLAN600 anywhere. That possibly makes sense for VLAN 600 as there are no loops that I can tell based on what you've told me.
For VLAN603 I see there are two port channels to the external firewall, why is that? Is the firewall participating in STP in any way? Are there any other L2 devices involved?
