Which command shows the current configured IP addresses and subnet masks on a router or switch?

The command that displays the current configured IP addresses and subnet masks on a router or switch is indeed the one that specifically focuses on interfaces. This command provides detailed information about each interface on the device, including the IP address assigned to it, the subnet mask, and the operational status. By using this command, network administrators can quickly verify the IP addressing scheme applied to the various interfaces, which is essential for troubleshooting connectivity or configuration issues.

Other commands, while useful in different contexts, do not provide the same level of detail regarding the specific IP configuration of interfaces. For instance, one command may show the running configuration but will present a broader view that includes other configuration parameters beyond just IP settings. Another command is used to display the routing table, which deals predominantly with how packets are routed between networks rather than showing the IP configurations of interfaces. Lastly, there is no standard command called "show ip configuration" in Cisco IOS, making it irrelevant in this context.

Thus, the command that directly allows you to see current IP addresses and subnet masks associated with the router or switch interfaces is appropriate for understanding the device's IP configuration.
