1.2.2 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.
1.2.2.1 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 VLAN1. Ports can belong to
other VLAN groups too.

1.3 Ways to Manage the Switch

Use the Web Configurator to manage the Switch. This allows easy Switch setup and management using
a (supported) web browser. See

1.4 Good Habits for Managing the Switch

Do the following things regularly to make the Switch more secure and to manage the Switch more
effectively.
• Change the password. Use a password that is not easy to guess and that consists of different types of
characters, such as numbers and letters.
• Write down the password and put it in a safe place.
