on of the first things I'd do is check interface statistics from the
inter-connecting interfaces for errors. On Cisco switches, the command is
fairly straight forward - show interface counters errors. All of the
numbers should be low if things are operating well...if you see more than
100 errors on any given port, it is probably worth investigating.
Question - are the floors connected by fiber or by copper?
