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 51

•

Command Line Interface. Line commands offer an alternative to the Web Configurator

and may be necessary to configure advanced features. See the CLI Reference Guide.

•

FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.

See

Section 29.8 on page 243

•

SNMP. The device can be monitored and/or managed by an SNMP manager. See

Section

30.3 on page 246

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.
