That is correct.

You see the RX dropped 5642? That's bad.
There's a chance that it's a bad ethernet cable; otherwise the
hub/switch is faulty. Given that it's labelled "switch" but all
the ports flash on every packet, it might well be that.
Unmanaged gigabit switches are cheap; I recommend that you
replace it if swapping cables doesn't solve the issue.
