Cd / etc/sysconfig/network-scripts/mv ifcfg-eno1677736 ifcfg-eth0

Vim / etc/default/grub;GRUB_CMDLINE_LINUX= "rd.lvm.lv=rhel/root crashkernel=auto rd.lvm.lv=rhel/swap vconsole.font=latarcyrheb-sun16 vconsole.keymap=us net.ifnames=0 biosdevname=0 rhgb quiet"

4. Add udev network card rule

Create a network card rule 70-persistent-net.rules file in the / etc/udev/rules.d directory.

Write the following parameters to the file:

SUBSYSTEM== "net", ACTION== "add", DRIVERS== "? *", ATTR {address} = = "MAC address of the Nic whose name needs to be modified", ATTR {type} = = "1", KERNEL== "eth*", NAME= "eth0"
