In the LAN network, a unique address is the combination of two addresses software address and hardware address. A unique address enables an end device to send and receive data in the network. Unless an end device has a unique address, it can’t communicate with other devices in the network. In network, an address provides a unique identity to an end device.

SNAP Protocol Numbers Registration Procedure(s) Expert Review Expert(s) Donald Eastlake (primary), Juan Carlos Zuniga (secondary) Reference Note The SNAP protocol number assignments use the IANA OUI. The CF series registry has been closed by. The registry for these is on the PPP Parameters IANA web page. The CFxxxx Series Note described a method of using a "pseudo OUI" forĬertain purposes when there is no appropriate regular OUI assigned.
