2 BC0054508-00 M
The Marvell BCM57xx and BCM57xxx adapters include a 10Mbps, 100Mbps,
1000Mbps, or 10Gbps Ethernet MAC with both half-duplex and full-duplex
capability and a 10Mbps, 100Mbps, 1000Mbps, or 10Gbps physical layer (PHY).
The transceiver is fully compatible with the IEEE 802.3 standard for
auto-negotiation of speed.
Using the Marvell teaming software, you can split your network into virtual LANs
(VLANs), as well as group multiple network adapters together into teams to
provide network load balancing and fault tolerance functionality.
 For detailed information about teaming, see Chapter 2 Configuring Teaming
in Windows Server and Chapter 11 Marvell Teaming Services.
 For a description of VLANs, see Chapter 3 Virtual LANs in Windows.
