One thing to note it's important that the F5 is set up for MIST (multi instance spanning tree), we got hit where a 10.4 device was still running single instance spanning tree (under network->spanning tree options). This was an artifact from when the box was running 9.x (which didn't support MIST), it was still set to single instance. When we added a newly created vlan to a trunk that terminates on a Nexus VPC (running MIST by default) went blocking, listening, leanrning, forwarding for all the vlans on the trunk causing a blip.
