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 0x46D1. 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.

Virtual NIC system number: 0 to 128 with LPAR manager expansion mode
With LPAR manager expansion mode, up to 16 virtual NICs can be assigned to one
LPAR. MAC addresses used by the system with Virtual NIC number 0 to 7, are
identical to those with LPAR manager standard mode. MAC addresses used by the
system with Virtual NIC number 8 to 15 are provided in the following string format.
Those MAC addresses are automatically generated 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 32 (0x0100 to 0x80FF)
Virtual NIC system number x 256 + (LPAR number – 1) x 8 + (Virtual NIC
number – 8)
2. LPAR 33 to 60 (0x8100 to 0xF0FF)
0x8100 + (Virtual NIC system number – 1) x 224 + (LPAR number – 33) x 8 +
(Virtual NIC number – 8)
