The Broadcom NetXtreme 57XX Gigabit Ethernet Controller connects a PCI, or
PCI-X (BCM5701 and BCM5703), or PCI Express™ (BCM5751 and BCM5721) compliant
server to a Gigabit Ethernet network. This network adapter incorporates a technology
that transfers data at a maximum rate of 1 gigabit per second�10 times the rate
of Fast Ethernet adapters.
The Broadcom NetXtreme 57XX Gigabit Ethernet Controller targets the increased
congestion experienced at the backbone and server in today�s networks and provides
a future upgrade path for servers that require more bandwidth than Fast Ethernet
can provide.
Using the Broadcom teaming software, you can split your network into virtual
LANs (VLANs) as well as to group multiple network adapters together into teams
to provide network load balancing and fault tolerance functionality. See Teaming
and Broadcom Gigabit Ethernet Teaming Services for
detailed information about teaming. See Virtual LANs,
for a description of VLANs. See Configuring Teaming
for instructions on configuring teaming and creating VLANs on Windows, Linux,
and NetWare operating systems.
Features
The following is a list of the Broadcom NetXtreme Gigabit Ethernet Adapter
features for all supported operating systems:
PCI Express™ x1 Lane support (BCM5751 and BCM5721)

not support Jumbo frames.
Layer-2 Priority Encoding (IEEE 802.1p)
High-speed on-chip RISC processor
Adaptive interrupt frequency
Up to 4 classes of service (CoS)
Up to 4 send rings and receive rings
Integrated 96 KB frame buffer memory
GMI/MII Management Interface
Statistics for SNMP MIB II, Ethernet-like MIB, and Ethernet MIB (IEEE Std
802.3z, Clause 30)
4 unique MAC unicast addresses
Support for multicast addresses via 128 bits hashing hardware function
Serial EEPROM or serial NVRAM flash memory
Supports PXE 2.1 specification (Linux Red Hat PXE Server, Windows 2000,
Windows Server 2003, Intel APITEST, DOS UNDI, Rembo Technology Auto-Deploy
Server, Windows NT 4.0 Remoteboot Server)
JTAG support
PCI v2.3 32/64-bit, 33/66 MHz Bus Interface (BCM5701, BCM5703)
PCI-X v1.0 64-bit 100/133 MHz Bus Interface (BCM5701, BCM5703)
PCI Power Management Interface (v1.1)
PCI Hot-Plug (IBM, Compaq, Dell, and Microsoft)
NOTE: The Dell hot-plug feature is Dell server-dependent.
PCI Express v1.0A, x1 or greater (BCM5721 and BCM5751)
ACPI and Wake on LAN support
64-bit BAR support
EM64T processor support
3.3 V/1.8 V CMOS with 5V tolerant I/Os
LiveLink™ (supported in both the 32-bit and 64-bit operating systems
of Linux and Windows)
Power Management
Wake on LAN (Magic Packet, Wake Up Frame, specific pattern) is supported at
10/100 Mbps operation only.
NOTES:
Adapter speed connection when the system is down waiting for a wake-up
signal is either 10 Mbps or 100 Mbps, but can return to 1000 Mbit/s
when the system is up and running if connected to a 1000 Mbps capable
switch. Systems intending to use WOL should be connected to a switch
capable of both 1000 and 10/100 Mbps speeds.
Dell supports Wake on LAN on one device in the system at a time.
Adaptive
Interrupt Frequency
The adapter driver intelligently adjusts host interrupt frequency based on
traffic conditions, to increase overall application throughput. When traffic
is light, the adapter driver interrupts the host for each received packet, minimizing
latency. When traffic is heavy, the adapter issues one host interrupt for multiple,
back-to-back incoming packets, preserving host CPU cycles.
Dual DMA Channels
The PCI interface on Broadcom NetXtreme 57XX Gigabit Ethernet controllers contains
two independent DMA channels for simultaneous read and write operations.
32-Bit or 64-Bit PCI Bus Master
Compliant with PCI Local Bus Rev 2.3, the PCI interface on Broadcom NetXtreme
57XX Gigabit Ethernet controllers is compatible with both 32-bit and 64-bit
PCI buses. As a bus master, the adapter requests access to the PCI bus, instead
of waiting to be polled.
ASIC with Embedded
RISC Processor
The core control for Broadcom NetXtreme 57XX Gigabit Ethernet controllers resides
in a tightly integrated, high-performance ASIC. The ASIC includes a RISC processor.
This provides the flexibility to add new features to the card and adapt it to
future network requirements through software downloads. This also enables the
controller drivers to exploit the built-in host offload functions on the controller
as host operating systems are enhanced to take advantage of these functions.
Broadcom Advanced Control Suite 2
Broadcom Advanced Control Suite 2 (BACS2), a component of the Broadcom teaming
software, is an integrated utility that provides useful information about each
network adapter that is installed in your server. The BACS2 utility also enables
you to perform detailed tests, diagnostics, and analyses on each adapter, as
well as to modify property values and view traffic statistics for each adapter.
BACS2 is used on Windows operating systems to configure teaming and to add VLANs.
See Broadcom Advanced Control Suite 2 for detailed information
and instructions.
Supported Operating Environments
The Broadcom NetXtreme 57XX Gigabit Ethernet Controller has software support
for the following operating systems:
Microsoft® Windows® (32-bit and 64-bit extended)
Linux® (32-bit and 64-bit extended)
MS-DOS®
NetWare®
Network Link and Activity Indication
The state of the network link and activity is indicated by the LEDs on the
RJ-45 connector, as described in Table 1. Broadcom
Advanced Control Suite 2 also provides information about the status of the network
link and activity (see Vital Sign).
