Self IP not functioning

I would need to see your selfip, vlan, interface, VS configuration to be able to offer up better assistance. But in general, you want to make sure your vlans, vlan tags and associated interfaces are the same on all 3 devices. then, make sure each device has it's own self ip in the appropriate subnet. Then, make sure there's a floating self IP for each traffic group.

Validate under Device Management, then traffic groups in the GUI, that the associated IP addresses for these floating IP's show up in the correct traffic group.
