Centos6.5 update e1000 NIC Driver

Centos6.5 update e1000 NIC Driver
GuideDuring work, I often encounter abnormal network conditions in the linux operating system. I did not notice it before. Today, I checked the system logs and found it was a network-driven problem. Simply update the system and update the network card.Problem: the linux system often suffers from network disconnection. After restart, the system returns to normal.

When the network is disconnected, you can view the system through ipmi and find that the system is running normally, but you cannot connect to the network. Go to the system log to find it and send an error:

By searching on the internet, we found a problem with the NIC driver. The solution on the Internet is to update the NIC Driver. Because I did not personally test the NIC driver, this time I passed the"Yum-y update "updates the system and the NIC Driver

The system is updated, and the NIC is also updated. The following shows whether the system Nic is normal.
