Virtual NIC #0 of LPAR1 is assigned to segment Vc in the figure above. It can
communicate with virtual NIC #1 of LPAR2 but cannot communicate with #2. Virtual
NIC #2 of LPAR2 can communicate only with virtual NIC #2 of LPAR1 in the same
segment Va.
(2) Shared NIC
With LPAR manager, network segments for shared NICs can be set to the physical
LAN controller assigned to shared mode. By defining connections between these
network segments and the shared NICs, you can perform communication with
external networks. Network segments for shared NICs can be set on the Virtual NIC
(VNIC) Assignment screen.
In these network segments, shared NICs connected to the same network segment
can communicate without going through a physical LAN controller. However,
communication among shared NICs in different network segments needs to use an
external network via a physical LAN controller.
The following table shows the number of physical LAN controllers to be assigned to
LPAR manager.

When a virtual NIC is used, the
guest OS recognizes it as 1 Gb
LAN (Intel PRO/1000 or Intel
82576 specifications).
With a virtual NIC function,
virtual NIC of 1 Gb LAN (Intel
82546 or Intel 82576
specifications) can be
assigned to an LPAR defined
on LPAR manager.
