How can you display port security status of individual interfaces?

1. #show interfaces status

2. #show port-security

3. #show port-security interface INTERFACE

4. #show mac-address table

The correct answer is: #show port-security interface INTERFACE

The command to display the port security status of individual interfaces is indeed tailored to target specific interfaces for detailed information. Using the command that includes "interface INTERFACE" allows you to specify which interface you want to check. This is beneficial because it provides a focused view of port security configurations and violations for that particular interface, allowing for easier troubleshooting and management of security settings. In contrast, the general command for port security does provide an overview of port security across the device, but it does not drill down into details on individual interfaces. Other commands like checking interface status or the MAC address table offer insight into broader operational states and learned addresses but do not specifically address port security configurations or statuses.
