What does the show interface command do?

The show interface command is a crucial tool in network management as it generates comprehensive details about the status and configuration of switch interfaces. This command gives network administrators insights into various aspects of network interfaces, such as their operational state (up or down), configuration settings, speed, duplex mode, error statistics, and other interface-specific parameters. By using this command, administrators can monitor the performance of interfaces, troubleshoot connectivity issues, and verify that configurations are applied correctly, making it an essential part of maintaining network health and effectiveness.

The other options relate to functionalities that are not provided by the show interface command, allowing for a clear understanding that this command is specifically designed for interface status and configuration rather than software versioning, bandwidth metrics, or VLAN configurations.
