- <Structure of this section>
(1) MAC address of the device
The Switch has one MAC address as a device identifier. This MAC address is called the device MAC address. A device MAC address is used as a MAC address in a Layer 3 interface or as a device identifier used in a protocol such as the Spanning Tree Protocol.
(2) Ability to use device MAC addressing
The following table describes the types of functionality that use the device MAC address.
