nmcli is NetworkManager's built-in command-line interface added in 2010[1], it is used at least in RHEL. nmcli allows easy display of NetworkManager's current status, manage at least Ethernet and WiFi connections and devices, monitor connections.


Basic Commands[edit]

See RHEL 8.0 official documentation: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/configuring_and_managing_networking/index

Configure commands[edit]

  • Configure DNS: nmcli con mod test-lab ipv4.dns "8.8.8.8 8.8.4.4"
  • Activate Ethernet connection: nmcli con up test-lab ifname ens9
  • View details: nmcli -p con show test-lab
  • Configure IP in eth0:
nmcli c add type ethernet ifname eth0 con-name "My_New_Connection" ip4 192.168.1.166/24 gw4 192.168.1.1
Connection "My_New_Connection"  (xxxxxxx-sdafasfsdf-adfasdfaf-adsfads) suceessfully added.
