High rate of errors - is this normal?
nOn my Netgate pfSense router, I'm seeing what looks like a pretty high amount of errors on both the LAN and the WAN interface. This router is connected to an internal 1G switch (LAN) and to a 1G port on an Xfinity router (WAN). Throughput and traffic is fine, it peaks at around 700Mbps in / 40Mbps out on the WAN port.

And I'm seeing the following number of errors (and they continuously keep going up):
It's almost as if every packet is an error ?? :-)
No that is not at all normal. What is this hardware?
That many errors would typically imply either a negotiation problem (one side hard coded speed/duplex, the other on autonegotiate stuck at half duplex) or a physical problem such as a bad cable.
I don't think it could be a duplex mismatch because it's running at 1Gb and 1Gb is always full-duplex, at least for Ethernet. And since they're seeing 700Mb/s, it has a to be a true 1Gb link.
Stranger things have happened, only way to know is to check the
ifconfigoutput and see what it reports.
System Netgate SG-2440
I've checked cables etc., I see no packet loss even under heavy load, and throughput through the router (from LAN -> router -> WAN) is normal (~700Mbps, which is likely a limitation on the Xfinity side and not the router).
