Explanation:
The command dladm is used to configure data-link interfaces in Sun Solaris. A configured data-link is
represented in the system as interface that can be used for TCP/IP. Each data-link relies on either a single
network device or an link aggregation device to send & recieve packets.
Network interfaces provide the connection between the system and the network. These interfaces are
configured over data links, which in turn correspond to instances of hardware devices in the system.
In the current model of the network stack, interfaces and links on the software layer build on the devices in the
hardware layer. More specifically, a hardware device instance in the hardware layer has a corresponding link onthe data-link layer and a configured interface on the interface layer. This one-to-one relationship among the
network device, its data link, and the IP interface is illustrated in the figure that follows.
