The Solaris operating system supports the TCP/IP networking model. Although Solaris can use several types of networking hardware architectures, such as Ethernet, Token Ring, and Fiber Distributed Data Interface (FDDI), to communicate with other systems, Ethernet is the de facto networking architecture.
The TCP/IP model's Data Link layer controls data transfer across network media. In an Ethernet local area network (LAN), the Ethernet frame is used at the Data Link layer to package and transmit the data.
The hosts on an Ethernet LAN are assigned unique addresses that are associated with the Data Link layer. These addresses are referred to as Ethernet addresses, hardware addresses, physical
