XX.XX.XX Fixed at 00.00.87 to indicate Hitachi
(Vendor ID)
YY.YY Eight higher order bits of the offset value
is taken out and added to 0x1C7F. Then
endian conversion is performed.
ZZ Eight lower order bits of the offset value
*1: The MAC address format above is not applied to LPARs that have performed
migration,
*2: The user cannot set a value that duplicates the MAC address automatically
generated by LPAR manager. Do not set a multicast address and broad cast
address.

MAC address is provided in the following format in the system with Virtual NIC
number 129 or greater. MAC address is automatically created by LPAR manager.
MAC address format:
Calculate the offset value from the base point with the followings to generate a MAC
address.
1. LPAR 1 to 16
(Virtual NIC system number - 129) x 1024 + (LPAR number – 1) x 16 + Virtual
NIC number
2. LPAR 17 to 32
(Virtual NIC system number - 129) x 1024 + 256 + (LPAR number – 17) x 16 +
Virtual NIC number
