Displaying the Device Serial Number
You can use the display commands to view the serial number of a device.
Context
A device serial number includes a unique equipment serial number (ESN) of the device and a serial number (SN) of each independent component (for example, card, power module, and fan module).
When you need technical assistance or have to apply for a license, you need to provide the device serial number.

What Are the Differences Between ESN and SN?
When you need technical assistance or have to apply for a license, you need to provide the equipment serial number (ESN).
The ESN is a unique identifier of a device. When an independent component of a device is faulty, you need to provide the SN of the component. For details, see Displaying the Device Serial Number.
