Ieee802.1Q Vlans; Configuring The Vlan Settings - D-Link DGE-530T Manual

DGE-530T Gigabit Ethernet Adapter Card
such as video-conferencing, is of a higher priority, with a slight delay of packets resulting in
noticeable degeneration of video and audio quality, while other traffic, such as email will not be
noticeably affected by tiny delays. The large number of programs run over today's networks
serves to impede the ability to deliver time-critical data. Even if bandwidth is not usually a
problem on your network, during peak hours bursts in network traffic can result in the delay of
time-critical traffic.
IEEE802.1p defines seven levels of prioritization for Ethernet packets. High priority packets will
be sent through a network using 802.1p-compliant switches first. Lower priority packets will be
transferred whenever bandwidth is available. When properly setup, this ensures that time-critical
data arrives on time and is not affected by other traffic.

IEEE802.1Q VLANs

The IEEE802.1Q VLAN can help improve network performance and security by segmenting the
network into VLANs. IEEE802.1Q VLANs can limit broadcast and node-to-node (unicast) traffic to
a single VLAN. This limits the effects of broadcast storms and provides additional security for
your network.
For VLANs to function, the computer in which this NIC is installed must be using Windows 2000,
XP, 2003 or later as its operating system.

Configuring the VLAN Settings

To configure the VLAN settings for your DGE-530T, first open the D-Link Network Control utility
located in the control panel of your computer, as shown below.
Once opened, click the Virtual LAN tab at the top of the page, which will display the following
screen. Click the "D-Link DGE-530T Gigabit Ethernet Adapter" link, which will display the
settings in the bottom half of the window.
