You perform network configuration at the datalink layer by using the dladm command.
The following are some of the types of datalink configuration that can be performed at this layer:
Basic network configuration of physical links
Configuration of VNICs (virtual links over physical links)
For VNIC configuration, each virtual link has it's own MAC address
Link aggregation configuration
Aggregations are configured over physical links for reliability and performance.
Etherstubs for supporting virtual local area networks (VLANs)
Bridges for supporting VLANs
For other examples, see Managing Network Datalinks in Oracle Solaris 11.2 .
