DNCA on RHEL - Configuring Network Interfaces

The network configuration files in the /etc/sysconfig directory are read and processed during system initialization. To apply changes, eboot the machine by using the command shutdown -r now.

• Instead of rebooting the machine, you can also bring the machine into single-user mode by using the command shutdown now. At the command prompt, enter the command exit to leave single-user mode and reenter multi-user mode, which enables networking and starts the network interfaces.
