Gigabit Ethernet To The Desktop; Ieee 802.1Q Vlan Application Example - ZyXEL Communications GS1900 Series User Manual

1.2.4 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.
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.

1.2.5 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 groups unless such traffic first goes through
a router.
For more information on VLANs, refer to
1.2.5.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, therefore 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.
