Solution to Linux dual-nic machine failure to access the Internet

The company server is a dual-nic and installed with RHEL. After a period of time, the MAC address of the NIC changes to Fe: FF: ff, and the network cannot be accessed, to solve this problem, follow these two steps:

1. Choose system> Management> network. On the hardware tab, delete and save all the visible hardware.

2. Shut down and shut down the power supply. After a period of time, start the computer and go to the system again-> Management-> network. Now, you can only see the NIC information of the network cable, after setting the IP address, you can access the Internet normally.
