In this example we can see that:

  • A single interface exists on the system: dp0s4
  • This interface is receiving (rx) packets with errors
  • This interface is dropping some of the packets that it is receiving — this may be an expected result of the quality of service (QoS) or firewall configuration
Note: Interface errors are not typical. If you find that there is a consistent increase in the number of errors then this may indicate a problem with the interface, the cable, or the connected network element.
