Syntax

View
System view
Parameter
level:
Command level, in the range of 0 to 3.
view:
Command view. It can be any command view that the S3100-52P Ethernet switch
support.
command:
Command to be set.
Description
Use the command-privilege level command
to set the level of the specified command in specified view.
Use the undo command-privilege view
command to restore the default level of the specified command in specified
view.
All commands fall into four levels: visit,
monitor, system, and manage, which are identified as 0, 1, 2, and 3,
respectively. The administrator can change the level of a command as required
so that the command can operate in corresponding view.
By default, the ping, tracert,
and telnet commands are at the visit level (level 0), the display
and debugging commands are at the monitor level (level 1), all
configuration commands are at the system level (level 2), and FTP, XModem, TFTP
and file system related commands are at the manage level (level 3).
Example
# Set the level of the interface
command in system view to 0.
<H3C> system-view
System View: return to User View with
Ctrl+Z.

Syntax
super [ level
]
View
User view
Parameter
level: User
level, in the range of 0 to 3 with a default of 3. If you execute this command
with the level argument not provided, you switch from the current user
level to level 3.
Description
Use the super command to switch from
the current user level to the one specified by the level argument. If you
have set a password by using the super password [ level level
] { simple | cipher } password command, you need to
provide the password when switching the user level. Otherwise, you will remain at
the original user level.
Note that:
l
Users logging in to a switch also fall into four
levels, which respectively correspond to the command levels. Users at a
specific level can only use the commands at the same or lower levels.
l
AUX users can determine whether to use the super
password [ level level ] { simple | cipher
} password command to set a password for the switching from a lower user
level to a higher user level. If a password is set, AUX users must enter the
password correctly when switching from the current level to a higher level.
Otherwise, they will remain at the original user level. If no password is set,
they will directly switch from the current user level to a higher user level.
l
VTY users must use the super password [
level level ] { simple | cipher } password
command to set a password for the switching from a lower user level to a higher
user level. If no password is set, “Password is not set” will be
displayed when they switch the user level, indicating that the switching fails
and they remain at the original user level.
l
AUX users or VTY users can switch from a higher
user level to a lower user level, no matter whether a switching password is
set.
Related command: super password.
Example
# Switch to user level 3.
<H3C> super 3
Password:
Syntax
super password [ level level ] { simple | cipher
} password
undo super password [ level level ]
View
System view
Parameter
level: User
level, in the range of 1 to 3 with a default of 3. If you execute this command
with the level argument not provided, you will set a password for
yourself as a user of level 3.
simple:
Specifies to provide the password in plain text.
cipher:
Specifies to provide the password in cipher text.
password: Password
string to be set. If you specify the simple keyword, you must provide
the password in plain text. If you specify the cipher keyword, you can
provide the password in either cipher text or plain text. In plain text mode, the
password contains up to 16 characters (for example 123) and the system
automatically converts it into a 24-character ciphered password (for example, !TP<\*EMUHL,408`W7TH!Q!!).
In cipher text mode, you can directly provide a 24-character ciphered password (for
example, !TP<\*EMUHL,408`W7TH!Q!!), but you must know the corresponding
plain password (for example, 123).
Description
Use the super password command to
set a password for a higher level user who is switched from a lower user level.
To prevent unauthorized accesses, the system requires you to enter the password
for the higher level user. For the purpose of security, you cannot see the
password you enter. You will remain at the original user level if you fail to
enter the correct password after you have tried more than three times.
Use the undo super password command
to remove the configuration.
Note that no matter whether you configure the
password in plain text or cipher text, you must enter the password in plain
text for authentication.
Example
# Set the password to “zbr” for
the switching from the current user level to user level 3.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] super password level 3 simple zbr
