On most modern Sun workstations and servers that MAC address is
stored in NVRAM (SGS-Thomson M48T02, M48T08, M48T59Y depending upon
the model of Sun). This is the same NVRAM that stores things like
boot device, nvramrc, input-device, etc. - although the methods for
modifying this ethernet address in NVRAM are not documented, at least
by Sun ;-)
The SS1000 and SC2000 are different in that, the MAC address is
stored in a flash eeprom.
In any case, this MAC address in NVRAM is the default MAC address for
all ethernet and fast ethernet interfaces. You can override this
default for any particular interface with ifconfig.
Typically this is only an issue when one wants to put two interfaces
on the same segment.
