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 9 on page 117.
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.
