Input/Output Interfaces

5.8 Network Interface Controller

These systems provide 10/100/1000 Mbps network support through an Intel 82567V network
interface controller (NIC), a PHY component, and a RJ-45 jack with integral status LEDs (Figure
5-10). The support firmware is contained in the system (BIOS) ROM. The NIC can operate in
half- or full-duplex modes, and provides auto-negotiation of both mode and speed. Half-duplex
operation features an Intel-proprietary collision reduction mechanism while full-duplex
operation follows the IEEE 802.3x flow control specification.

The Network Interface Controller includes the following features:
■
VLAN tagging with Windows XP and Linux
■
Multiple VLAN support with Windows XP (and later)
■
Power management support for ACPI 1.1, PXE 2.0, WOL, ASF 1.0, and IPMI
■
Cisco Etherchannel support
■
Speed and Activity LED indicator drivers
The controller features high and low priority queues and provides priority-packet processing for
networks that can support that feature. The controller's micro-machine processes transmit and
receive frames independently and concurrently. Receive runt (under-sized) frames are not passed
on as faulty data but discarded by the controller, which also directly handles such errors as
collision detection or data under-run.
