The Intelligent Way to Connect
The Intel^® 82571EB Gigabit Ethernet Controller
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.
