Gigabit Ethernet To The Desktop; Ieee 802.1Q Vlan Application Example - ZyXEL Communications XGS3700 Series User Manual

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
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.
