Ethernet Controller

High-performance, Dual-Port Gigabit Network Connectivity

for Servers and Embedded System Designs

10/100/1000 Ethernet connection

simplifies designs

Gigabit Ethernet (GbE) controllers for

flexible designs

The Intelligent Way to Connect

is a single, compact component with two fully

integrated Gigabit Ethernet Media Access Control

(MAC) and physical layer (PHY) ports. This device

uses the PCI Express architecture (Rev. 1.0a),

and also enables a dual-port Gigabit Ethernet

implementation in a very small area, which is

useful for server and workstation network designs

with critical space constraints. The Intel 82571EB

Gigabit Ethernet Controller provides two IEEE

802.3* Ethernet interfaces for 1000BASE-T,

100BASE-TX, and 10BASE-T applications.

Both ports also integrate a Serializer-Deserializer

(SerDes) to support 1000BASE-SX or 1000BASE-

LX (optical fiber) and Gigabit backplane

applications. In addition to managing MAC

and PHY Ethernet layer functions, the controller

manages PCI Express packet traffic across its

transaction, link, and physical/logical layers.

On-Board Management Features

The on-board System Management Bus (SMB)

and Fast Management Link (FML) ports of the

Intel 82571EB Gigabit Ethernet Controller enable

network manageability implementations required

by IT personnel for remote control and for alerting

via the LAN. With SMB, management network

packets can be routed to or from a management

processor. The SMB port enables industry

standards, such as the Intelligent Platform

Management Interface (IPMI) and Alert Standard

Format (ASF) 2.0, to be implemented using

the controller. In addition, connecting to a

management processor via the controller’s

FML port allows higher-speed management

traffic, such as keyboard, video and mouse

(KVM) data, to be sent via the LAN to a remote

management console. Both SMB and FML

operation use the standard SMB protocol and

allow enhanced pass-through implementations

using standardized interfaces.
