Which command provides detailed information about the components that are installed on a router, such as the model, PID, and serial number?

The show inventory command in Cisco IOS is designed specifically to display detailed hardware

inventory information about a Cisco device. This includes:

Component Name: The name or type of each module or card installed.

PID (Product ID): The unique product identifier for the module.

VID (Version ID): The version identifier for the module.

Serial Number: The unique serial number assigned to the module.

Why other options are incorrect:

show chassis: Some Cisco devices support a show chassis command, but the information provided

usually focuses on the physical chassis rather than detailed component inventory.

show items: This is not a standard Cisco IOS command.

show router: This command doesn't provide the level of granular hardware information that show

inventory does.
