How to Change the Speed of an Ethernet Port in Solaris
The UNIX-based Solaris operating system is generally only in large corporate server environments that require specialized hardware and software modules. If you are in charge of a Solaris server, you can change the speed at which it communicates over the Network Interface Card -- NIC, or Ethernet card -- by adjusting the speed inside of the operating system. Faster speeds enable faster data throughput, while slower speeds may be required for the computer or server to interface with certain hardware.
