1.1.2.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, and thus increase
network performance due to reduced 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.

1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 3 on page 33 .
• Command Line Interface. Line commands offer an alternative to the web configurator and
in some cases are necessary to configure advanced features. See the Command Reference
Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 15.8
on page 96 .
• SNMP. The Switch can be monitored by an SNMP manager. See Section 16.3 on page

1.3 Good Habits for Managing the Switch

different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
