Description (partial)

When Switch CoPP-Policy with strict values is applied subsequent switch software updates fail, because the SCP Filetransfer from APIC to Switch is stalled due to packets policed by CoPP. 

Filetransfer is extremely slow and eventually starts over but is never able to finish. 

After many hours of repetition APIC gives up and raises fault F1480.
