Yes, for sufficienly Unix-y routers/switches.
:I have used netstat -s on hosts to look at error counters if a switch or router was suspect.
:But that was a while ago (anyone remember when NFS corrupted all your files if one of your routers or the NIC had a bit error outside the protection provided by the Ethernet CRC?).

:Today, I have the problem that netstat -s doesnâ??t seem to work right on macOS.
:Many counter values are nonsensical, or simply zero.
:I was guessing this was due to NIC offload, but I havenâ??t analyzed further.
:If anyone knows more about recent macOS netstat -s, Iâ??d love to hear more details.
"sudo netstat -s" is your friend.
