A small problem encountered when setting the centos Network

Centos6.4 is installed. After the network is set, the network is poor.

Ethtool eth0 Error'

Settings for eth0: cannot get device settings: no such devicecannot get wake-on-LAN Settings: no such devicecannot get message level: no such devicecannot get Link Status: no such deviceno data available

Then under/etc/sysconfig/network-scripts/, found no ifcfg-eht0, but there is a ifcfg-p2p1.

Take a look at dmesg | grep eth0, one of which is:

Udev: renamed Network Interface eth0 to p2p1

The name was changed. Why?

For more information, see method 2,

Go to/etc/udev/rules. d/70-persistent-net.rules and change the name from p2p1 to eth0.

Then reboot, and then OK.
