Which command would be used to display all configured port security settings on the switch?

1. #show port-security

2. #display port-security settings

3. #show port-security status

4. #show security settings

The correct answer is: #show port-security

The command to use for displaying all configured port security settings on a switch is indeed the one that begins with "show port-security." This command provides detailed information about the port security status configured on a switch. It includes data such as the maximum number of secure MAC addresses allowed, the violation mode, and the current status of port security on each interface. Utilizing this command allows network administrators to quickly assess the security configurations of their switch ports, which is essential for maintaining a secure network environment and ensuring that unauthorized devices do not gain access to the network. The other commands listed would not yield the same detailed output regarding port security configurations. Some do not even follow standard command syntax used in Cisco IOS, which can lead to confusion and misconfigurations if attempted. Thus, using "show port-security" is the correct and standard approach for this purpose.
