How can the success of configuration changes be checked from the command line interface?

Checking the success of configuration changes from the command line interface can be effectively done by executing the command that displays the status of the interfaces on a device. The command that provides this information is used to show the IP address, status, and protocol state for all interfaces.

This command is valuable because it provides a quick overview of the operational status of all interfaces, indicating whether they are up or down, as well as confirming whether they are administratively up. If you've made configuration changes—such as assigning an IP address to an interface or enabling an interface—the output of this command will reflect those changes.

For example, if you configured an interface to be active, seeing it listed as 'up' in the output indicates that the configuration change was successful. If further configuration changes were made, like enabling or disabling certain features, this command could help verify those as well.

Other commands may provide insights into routing information, interface detailed settings, or testing connectivity, but the chosen command is specifically focused on directly showing the state of interfaces, making it the most relevant choice for confirming changes made to interface configurations.
