What is OUI address?

Typically, an OUI address refers to the first 24 bits of a MAC address (in binary notation) and is a globally unique identifier that IEEE assigns to a vendor. However, OUI addresses in this chapter are addresses that the system uses to identify voice packets.

What is the OUI of the source MAC address?

What is the OUI and why is it important?

Why is OUI important?

They are used to uniquely identify a particular piece of equipment through derived identifiers such as MAC addresses, Subnetwork Access Protocol protocol identifiers, World Wide Names for Fibre Channel devices or vendor blocks in EDID.

How is OUI calculated?

An Organizational Unique Identifier (OUI) is a code embedded in the first three bytes of a MAC address. It identifies the device’s vendor. For instance, if the first three bytes of your network adapter are 3C:FD:FE, your card was sold by Intel. To give an example, the MAC address of my laptop is 54:27:1E:44:EC:BA.
