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 4 on page 47 .
• Command Line Interface. Line commands offer an alternative to the web configurator and
in some cases are necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 26.8
on page 221 .
• SNMP. The Switch can be monitored by an SNMP manager. See Section 27.3 on page
224 .
• Cluster Management. Cluster Management allows you to manage multiple switches
through one switch, called the cluster manager. See Chapter 30 on page 247 .
1.3 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’s 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.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the Switch to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the Switch. You could simply restore your last configuration.
