CentOS 6.0 Network card Problem summary

Eth0 the missing treatment.

1. Just started to run ifconfig Eth0 found the NIC is missing.

[Root@localhost ~]# ifconfig eth0

Eth0:error fetching interface Information:device not found//But network-scripts the configuration files are all eth0, why not to get and do not know why?

The processing workaround can only replace eth0 with eth1, and create modprobe.conf files inside the alias Eth0 e1000e but not recognized.

2.[root@localhost network-scripts]# Mii-tool//view NIC connection status

eth1:negotiated 100basetx-fd, link ok

3.[root@localhost network-scripts]# ifconfig eth1//can find eth1 network card

4.[root@localhost network-scripts]# MV Ifcfg-eth0 ifcfg-eth1//modified eth0 for eth1

5.[root@localhost network-scripts]# VI ifcfg-eth1
