Thread: Question about interface statistics

  1. Question about interface statistics

    Hi Guys,

    I am running FreeBSD 7-Release/amd64

    I notice there are some errors on one of my network interfaces, netstat
    -i shows the following:

    [alex@nas ~]$ netstat -i
    Name Mtu Network Address Ipkts Ierrs Opkts
    Oerrs Coll
    em0 9000 00:0e:0c:da:27:a1 33365309 1003 54366493
    0 0

    The machine has 2 em() interfaces. em1 is connected to the LAN and has
    no errors, em0 is connected directly to a cable modem, what do the
    IERR's mean? Should I be concerned about them?

    I had my figures mixed up. em0 is connected to the lan, em1 is connected
    to the cable modem.

    The em0 interface is connected via cat 6 cable to a gigabit ethernet switch

    em0: flags=8843 metric 0 mtu 9000
    options=9b
    ether 00:0e:0c:da:27:a1
    inet 172.16.0.254 netmask 0xffffff00 broadcast 172.16.0.255
    media: Ethernet autoselect (1000baseTX )
