NetworkManager

The default Linux network configuration daemon, managed with nmcli, nmtui or GUI tools.

Definition

NetworkManager manages connection profiles stored in /etc/NetworkManager/system-connections (keyfile format on RHEL 9). nmcli can set static IPs, DNS, bonds, teams, bridges and VLANs, and changes apply after nmcli connection up.

Example

nmcli con mod eth0 ipv4.addresses 10.0.0.10/24 ipv4.gateway 10.0.0.1 ipv4.method manual

Exam tip

On RHEL, nmcli is the expected tool for persistent static IP configuration.
