Examining Network Activity - Sun Microsystems GigabitEthernet/S 2.0 Installation And User Manual

The network interface of the Sun GigabitEthernet adapter has been assigned a
unique MAC (Media Access Control) address, which represents the 48-bit Ethernet
address for that interface. The OpenBoot firmware reports this MAC address via the
local-mac-address property in the device nodes corresponding to the network
interface.
A system is not obligated to use this assigned MAC address if it has a systemwide
MAC address. In such cases, the system-wide MAC address applies to all network
interfaces on the system.
The device driver, or any other adapter utility, can use the network device's MAC
address (local-mac-address) while configuring it. In the Solaris 2.7 operating
environment, you will be able to use the MAC address when booting over the
network.
The mac-address property of the network device specifies the network address
(system-wide or local-mac-address) used for booting the system. To start using
the MAC address assigned to the network interface of the Sun GigabitEthernet
adapter, set the NVRAM configuration variable local-mac-address? to true.
ok setenv local-mac-address? true

Examining Network Activity

After you have verified the installation of the Sun GigabitEthernet adapter, but before
booting the system, examine the network interfaces with the OpenBoot PROM
watch-net-all command.
Make sure that the interface is connected to an active network.
