do folk use `netstat -s` to help diagnose on 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 doesn’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 haven’t analyzed further. If anyone knows more about recent macOS netstat -s, I’d love to hear more details. (Oh, and if there are recent (< 2 years old) statistics of ECT penetration in real networks, I’d love to know, too.) Grüße, Carsten
