• Simple Network Management Protocol (SNMP). Use to monitor and/or manage the Zyxel Device by
an SNMP manager. See (Section 30.2 on page 249).
• Secure Shell (SSH), Telnet. Use for troubleshooting the Zyxel Device by qualified personnel.
• FTP. Use FTP for firmware upgrades and configuration backup/restore.
1.4 Good Habits for Managing the Zyxel Device
Do the following things regularly to make the Zyxel Device more secure and to manage the Zyxel
Device more effectively.
• Change the WiFi and Web Configurator passwords. 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 passwords 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 Zyxel Device to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the Zyxel Device. You could
simply restore your last configuration.
