Configuration items for creating a user 

Username 

Set the username for a user 

Access Level 

Set the access level for a user. Users of different levels can perform different 

operations. 
Web user levels, from low to high, are visitor, monitor, configure, and 

management. 

z

 

Visitor: Users of visitor level can only use the network diagnostic tool ping 

and trace route. They can neither access the device data nor configure the 

device. 

z

 

Monitor: Users of this level can only access the device data but cannot 

configure the device. 

z

 

Configure: Users of this level can access data on the device and configure 

the device, but they cannot upgrade the host software, add/delete/modify 

users, or back up/restore the application file. 

z

 

Management: Users of this level can perform any operations on the device.

Password 

Set the password for a user 

z

 

When the password mode is Simple, the input password is in plain text.  

z

 

When the password mode is Cipher, the input password is either in plain text 

or cipher text with a length of 24 or 88. In this case, the input plain password 

with the length smaller than or equal to 16 will be converted to a cipher 

password with a length of 24; the input plain password with a length greater 

than 16 but smaller than 63 will be converted to a cipher password with a 

length of 88. When the length of the input password is 24, if the system can 

decrypt the password, it considers the password as a ciphertext password; if 

not, the system considers the password as a plaintext password. When the 

length of the input password is 88, if the system can decrypt the password, it 

considers the password as a ciphertext password; if not, the system prompts 

that the password is invalid. 

Confirm 

Password 

Input the same password again. Otherwise, the system prompts that the two 

passwords input are not consistent when you apply the configuration.  

Password 

Display Mode 

Set the password display mode. 

z

 

Simple: The password will be saved in the configuration file in plain text.  

z

 

Cipher: The password will be saved in the configuration file in cipher text, 

even if the password is input in plain text when configured.  

The plaintext password is not safe, and you are recommended to use the 

ciphertext password.  
No matter the password mode is set to Simple or Cipher, you must enter the 

password in the form of plain text for login authentication.  

Service Type 

Set the service type, including FTP and Telnet services. You must select either 

of them. 

 

In this part, users of the management level can specify the password for a lower-level user to switch 
from the current access level to the management level. If no such a password is configured, the 
switchover will fail.  
Select Device > Users from the navigation tree, and click the Super Password tab to enter the super 
password configuration page.
