Which command is used to check the status of the switch interfaces?

The command "show ip interface brief" is particularly valuable because it provides a concise summary of the status of all interfaces on a switch or router. It displays key information such as the interface's name, its IP address (if applicable), its status (up or down), and the protocol status. This streamlined view allows network administrators to quickly assess which interfaces are operational and which may have issues, making it an essential tool for troubleshooting and monitoring network devices.

In contrast, other commands might provide more detailed output or cover different aspects of the configuration. For instance, "show running-config" displays the entire current configuration of the device, which is much more extensive and not solely focused on interface status. "Show interfaces status" gives information but may not summarize IP address allocation like the chosen command does. "Verify ip interface" does not exist as a standard command in Cisco IOS and is not applicable in this context. Thus, "show ip interface brief" stands out as the most efficient way to check the status of switch interfaces effectively.
