There aren't going to be any substancial differences in the bit error rate
of the various mediums described (well - perhaps DSL may be worse depending
on what the parameters are for how aggressive you want it to be maximizing
performance vs reliability).

However if what you're asking whether pinging a switch and trying to read
the tea leaves of what its reported loss characteristics are for what is
essentially you pinging a rate-limited-control-plane (which is entirely
unrelated to forwarding other packets/frames in the data-plane), the short
answer is that its meaningless and won't tell you anything.

If you wish to test a link you need to find a device a hop away from it (or
end-to-end) to do your tests to/from.
