LAN Subsystem
The ethernet controllers support the following features:
• 10/100/1000 BASE-T IEEE 802.3 compliant
• Energy Efficient Ethernet (EEE) IEEE802.3az support (Low Power Idle [LPI]mode)
• Dual interconnect between the Integrated LAN Controller and the Physical Layer
(PHY):
PCI Express-based interface for active state operation (S0) state
SMBUS for host and management traffic (Sx low power state)
• Compliant to IEEE 802.3x flow control support
• 802.1p and 802.1q
• TCP, IP, and UDP checksum offload (for IPv4 and IPv6)
• Full device driver compatibility
In addition, the Intel 82579LM Gigabit Ethernet Controller supports Intel AMT, which is a
part of Intel’s vPro™ technology. The associated RJ-45 LAN connector has been colored
red for easy identification.
RJ-45 LAN Connector LEDs
The two LEDs are built into the RJ-45 LAN connector located on the back panel. These
LEDs indicate the status of the LAN as shown in Table 1.
