Moving from network scripts to Network Manager (nmcli) | Into the Terminal 118

For years Red Hat distributions managed network configuration through configuration files in /etc/sysconfig/network-scripts called ifcfg-* . However, over the last few years these files have been obsoleted and replaced by Network Manager and it's commandline tool: nmcli

Join us as take a look at moving into the world of managing network configuration with nmcli and Network Manager, it is incredibly powerful and exposes a lot more configuration options than what you were used to with networking scripts!

And if that was not enough, we'll briefly cover interface bonds (bonding), Using the network system role configure a bonded interface using ansible-core, an included component of RHEL.
