Configuration items for creating a user
Item Description
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.
Setting the Super Password
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.
