The command that displays an overview of ports with port security enabled is "show port-security." This command provides valuable insight into the port security features on a Cisco switch, including which ports have port security enabled, the maximum number of secure MAC addresses allowed on each port, the action taken when a security violation occurs, and the current status of the secured ports. Understanding this information is crucial for network administrators in managing network security, as it helps determine if the configuration aligns with the organization's security policies.

In contrast, the other options do not correspond to valid commands for viewing port security settings. "Display ports," for instance, might suggest a general view of port statuses, but it does not specifically address port security configurations. Similarly, "show security-status" and "list port-security" are not standard commands recognized in Cisco IOS for this purpose, further reinforcing that they wouldn't provide the necessary information regarding port security.
