The /HOST macaddress property is automatically configured by the system software, so you cannot set or change the property. The value is read and determined from the server’s removable system configuration card (SCC PROM) and then stored as a property in ILOM.
/HOST macaddress is the MAC address for the net0 port. The MAC addresses for each additional port increments from the /HOST macaddress. For example, net1 is equal to the value of /HOST macaddress plus one (1).
