1.1  CLI Configuration Commands

1.1.1  command-privilege level

Syntax

command-privilege level level view view command

undo command-privilege view view command

View

System view

Parameters

level level: Command level to be set, in the range of 0 to 3.

view view: CLI view. It can be any CLI view that the Ethernet switch supports. The S3100-52P switches support only the CLI views listed in Table 1-1:

Table 1-1 Available CLI views for the view argument

command: Command for which the level is to be set.

Description

Use the command-privilege level command to set the level of a specified command in a specified view.

Use the undo command-privilege view command to restore the default.

Commands fall into four levels: visit (level 0), monitor (level 1), system (level 2), and manage (level 3). The administrator can change the level of a command as required. For example, the administrator can change a command from a higher level to a lower level so that the lower level users can use the command.

The default levels of commands are described in the following table:

Table 1-2 Default levels of commands

Examples

# Set the level of the system-view command in user view (shell) to 0.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] command-privilege level 0 view shell system-view

1.1.2  display history-command

Syntax

display history-command

View

Any view

Parameters

None

Description

Use the display history-command command to display the history commands of the current user, so that the user can check the configurations performed formerly.

History commands are those commands that was successfully executed recently and saved in the history command buffer. You can set the size of the buffer by the history-command max-size command. When the history command buffer is full, the earlier commands will be overwritten by the new ones.

By default, the CLI can save 10 history commands for each user.

Related commands: history-command max-size in login module.

Examples

# Display the history commands of the current user.

<Sysname> display history-command

  system-view

  quit

  display history-command

1.1.3  super

Syntax

super [ level ]

View

User view

Parameters

level: User level, in the range of 0 to 3.

Description

Use the super command to switch from the current user level to a specified level.

Executing this command without the level argument will switch the current user level to level 3 by default.

Note that:

l           Users logged into the switch fall into four user levels, which correspond to the four command levels respectively. Users at a specific level can only use the commands at the same level or lower levels.

l           You can switch between user levels after logging into a switch successfully. The high-to-low user level switching is unlimited. However, the low-to-high user level switching requires the corresponding authentication. The authentication mode can be set through the super authentication-mode command.

l           For security purpose, the password entered is not displayed when you switch to another user level. You will remain at the original user level if you have tried three times but failed to enter the correct authentication information.

Related commands: super authentication-mode, super password.

Examples

# Switch from the current user level to user level 3, using super password authentication.

<Sysname> super 3

 Password:

User privilege level is 3, and only those commands can be used

whose level is equal or less than this.

Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE

# Switch from the current user level to level 3, using HWTACACS authentication.

<Sysname> super 3

 Username: user@system

 Password:

User privilege level is 3, and only those commands can be used

whose level is equal or less than this.

Privilege note: 0-VISIT, 1-MONITOR, 2-SYSTEM, 3-MANAGE

1.1.4  super authentication-mode

Syntax

super authentication-mode { super-password | scheme }*

undo super authentication-mode

View

User interface view

Parameters

super-password: Adopts super password authentication for low-to-high user level switching.

scheme: Adopts Huawei terminal access controller access control system (HWTACACS) authentication for low-to-high user level switching.

Description

Use the super authentication-mode command to specify the authentication mode used for low-to-high user level switching.

Use the undo super authentication-mode command to restore the default.

By default, super password authentication is adopted for low-to-high user level switching.

Note that the two authentication modes are available at the same time to provide authentication redundancy. When both the two authentication modes are specified, the order to perform the two types of authentication is determined by the order in which they are specified, as described below.

l           If the super authentication-mode super-password scheme command is executed to specify the authentication mode for user level switching, the super password authentication is preferred and the HWTACACS authentication mode is the backup.

l           If the super authentication-mode scheme super-password command is executed to specify the authentication mode for low-to-high user level switching, the HWTACACS authentication is preferred and the super password authentication mode is the backup.

l           When both the super password authentication and the HWTACACS authentication are specified, the device adopts the preferred authentication mode first. If the preferred authentication mode cannot be implemented (for example, the super password is not configured or the HWTACACS authentication server is unreachable), the backup authentication mode is adopted.

Examples

# Specify HWTACACS authentication as the preferred authentication mode when a VTY 0 user switches from the current level to a higher level, with the super password authentication as the backup authentication mode.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] user-interface vty 0

[Sysname-ui-vty0] super authentication-mode scheme super-password

1.1.5  super password

Syntax

super password [ level level ] { cipher | simple } password

undo super password [ level level ]

View

System view

Parameters

level level: User level, in the range of 1 to 3. It is 3 by default.

cipher: Stores the password in the configuration file in ciphered text.

simple: Stores the password in the configuration file in plain text.

password: Password to be set. If the simple keyword is used, you must provide a plain-text password, that is, a string of 1 to 16 characters. If the cipher keyword is used, you can provide a password in either of the two ways:

l           Input a plain-text password, that is, a string of 1 to 16 characters, which will be automatically converted into a 24-character cipher-text password.

l           Directly input a cipher-text password, that is, a string of 1 to 24 characters, which must correspond to a plain-text password. For example, The cipher-text password “_(TT8F]Y\5SQ=^Q`MAF4<1!!” corresponds to the plain-text password 1234567.

Description

Use the super password command to set a switching password for a specified user level, which will be used when users switch from a lower user level to the specified user level.

Use the undo super password command to restore the default configuration.

By default, no such password is set.

Note that, no matter whether a plain-text or cipher-text password is set, users must enter the plain-text password during authentication.

Examples

# Set the switching password for level 3 to 0123456789 in plain text.

<Sysname> system-view

System View: return to User View with Ctrl+Z.

[Sysname] super password level 3 simple 0123456789
