The `no shutdown` command, when applied within the configuration context of a loopback interface, administratively enables the interface, ensuring it is active and operational to process traffic.

Renaming an interface typically requires a specific command like `interface LoopbackX name new_name` (not standard in IOS for loopback) or removing and re-creating the interface, not `no shutdown`.

Deleting an interface is performed using the `no interface LoopbackX` command, which is distinct from `no shutdown`.

Displaying interface information is done with `show` commands, such as `show ip interface brief` or `show interface Loopback0`, not by configuration commands.
