1.1.3 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth for a group
of heavy traffic users. You can connect computers and servers directly to the Switch’s port or
connect other switches to the Switch. Use the optional 10 Gigabit uplink module to provide
high speed access to a data server and the Internet. The uplink module supports a fiber-optic
connection which alleviates the distance limitations of copper cabling.
In this example, all computers can share high-speed applications on the server and access the
Internet. To expand the network, simply add more networking devices such as switches,
routers, computers, print servers and so on.

1.1.4 IEEE 802.1Q VLAN Application Example
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one or more groups. With
VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s)
unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 8 on page 87.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, thus increasing
network performance by reducing broadcast traffic. VLAN groups can be modified at any time
by adding, moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In
the following figure only ports that need access to the server need to be part of VLAN 1. Ports
can belong to other VLAN groups too.
