Introduction

Thank you for choosing D-Link DGE-550T, the value
leader among multi-speed adapters for PCI Bus
personal computers. This introduction gives a general
description of the newer networking technologies found
on the DGE-550T.
The DGE-550T provides the bandwidth capability to
support high-end servers and workstations. With Auto-
negotiation, this card can run on three different speeds:
10/100Mbps, both half- and full-duplex, and 1000Mbps
at full duplex. When running at 1000Mbps, it provides a
network throughput of 2Gbps in full-duplex mode.
The card supports IEEE 802.1p Traffic Prioritization for
time-sensitive and mission-critical traffic. With IEEE
802.1Q VLAN support, it provides VLAN tables that can
filter packets by recognized VLAN tags, strip VLAN tags
when received, and insert VLAN tags when transmitted.
VLANs can increase efficiency and provide extra security
for your network.
The DGE-550T provides IEEE802.3x Flow Control
Enhancements, which are needed for a network adapter
to function with a switch. In full-duplex mode, MAC
implements the PAUSE control function. This means
when a switch is connected in full-duplex mode and it
senses that its buffer will overflow in the near future,
