Use any of the following methods to manage the ZyXEL Device.

• Web Configurator. This is recommended for everyday management of the ZyXEL Device 

using a (supported) web browser. See 

. 

• Command Line Interface. Line commands are mostly used for troubleshooting by service 

engineers. 

• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.  
• SNMP. The device can be monitored and/or managed by an SNMP manager. See 

. 

• TR-069. This is a standard that defines how your ZyXEL Device can be managed by a 

management server. See 

. 

Do the following things regularly to make the ZyXEL Device more secure and to manage the 
ZyXEL Device 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 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.
