ifconfig eth0 show errors

saavik · 06-18-2010, 03:21 AM

today i found some errors in my ifconfig for eth0

errors:1777

What could that be ?
What does errors mean in this case ?

There is a virtual machine running on that server. Could that case the errors ?

Code:

eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx 
          inet addr:xx.xx.xx.xx  Bcast:10.255.255.255  Mask:255.0.0.0
          inet6 addr: xxx:xxx:xxx:xx/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:760365536 errors:1777 dropped:0 overruns:0 frame:0
          TX packets:1121493018 errors:0 dropped:0 overruns:0 carrier:0

Could be a number of things.
Faulty nic, faulty cable or rj45 connectors, duplex mismatch.

I would start with checking the duplex.

mii-tool eth0

or

ethtool eth0

The duplex and interface speed setting should match that of its partner (eg switch or router).
So if the switch port is set at 100 FD, then the eth0 should be set on that.

If that is not the problem, then the nic itself or cables or switch/router ports would be the next place to check.

Forgot to add...the errors will only be an issue if they are currently increasing.

you need to install and map the correct drivers for your device

Well, ok mii-tool says:

# mii-tool eth0
eth0: no autonegotiation, 10baseT-HD, link ok

The other side is an Cisco Router, if that does anything...

I am now about to switch the cable. Does anybody have any futher ideas ?

NO, dont switch the cable yet.

10baseT-HD, link ok - does not seem correct in this day and age when todays interfaces are capable of 100baseT-FD.
could be worth checking the communication of the cisco network device interface. this must match the eth0 on the linux box.
my guess is that it is 100baseT-FD auto negotiation.
Most likely you need to switch the duplex settings on eth0 on linux box.
Fortunately for you, mii-tool will do this too.

man mii-tool
