We're using PfSense as an internal router/firewall (no connection to WAN). Using the Web-GUI, under Status ---> Interfaces, there's one particular interface where I have some errors:
In/out errors 3513/0
I then SSHed to the firewall to validate the info provided by the WebGUI and here's the output:
# netstat -ni -I bce2 Name Mtu Network Address Ipkts Ierrs Opkt Oerrs Coll bce2 1500 <Link#3> 00:23:7d:cd:a2:a2 1404522323 3513 749797131 0 0 bce2 1500 10.42.1.0/24 10.42.1.24 6 - 6 - -
As you can see, both present the same info (errors on incoming packets). I switched cables, changed network card, changed port on switch and I still see the errors. My 2 questions really are:
1) Is there any way I could get more info on the nature of these errors? or is this all I can get?
2) Should I be worried about this? As you can see, the errors are a VERY LOW percentage of all the total incoming packets. In other words, is this normal on a high-traffic gigabit interface?
