Syntax

command-alias enable

undo command-alias enable

View

System view

Default level

2: System level

Parameters

None

Description

Use the command-alias enable command to enable the command alias function.

Use the undo command-alias enable command to disable the command alias function.

By default, the command alias function is disabled.

Examples

# Enable the command alias function.

<Sysname> system-view

[Sysname] command-alias enable

# Disable the command alias function.

<Sysname> system-view

[Sysname] undo command-alias enable

command-alias mapping

Syntax

View

System view

Default level

2: System level

2

Parameters

cmdkey: The complete form of the first keyword of a command.

alias: Specifies the command alias, which cannot be the same as the first keyword of an existing

command.

Description

Use the command-alias mapping command to configure command aliases.

Use the undo command-alias mapping command to delete command aliases.

By default, a command has no alias.

Examples

# Configure command aliases by specifying show as the replacement of the display keyword.

<Sysname> system-view

[Sysname] command-alias mapping display show

After you configure the command aliases, the display commands have aliases. For example, if the

original command is display clock, now its alias is show clock and you can input the alias to view the

system time and date.

# Delete the command aliases by canceling the replacement of the display keyword.

<Sysname> system-view

[Sysname] undo command-alias mapping display

command-privilege level

Syntax

command-privilege level level view view command

undo command-privilege view view command

View

System view

Default level

3: Manage level

Parameters

level level: Command level, which ranges from 0 to 3.

view view: Specifies a view.

command: Command to be set in the specified view.

Description

Use the command-privilege command to assign a level for the specified command in the specified view.

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

By default, each command in a view has a specified level.

Command levels include four privileges: visit (0), monitor (1), system (2), and manage (3). You can

assign a privilege level according to the user’s need. When logging in to the switch, the user can access

the assigned level and all levels below it.

3

• Level changes can cause maintenance, operation, and security problems. H3C recommends that

you use the default command level or that you modify the command level under the guidance of

professional staff.

• The command specified in the command-privilege command must be complete, and has valid

arguments. For example, the default level of the tftp server-address { get | put | sget }

source-filename [ destination-filename ] [ source { interface interface-type interface-number | ip

source-ip-address } ] command is 3. After the command-privilege level 0 view shell tftp 1.1.1.1 put

a.cfg command is executed, when users with the user privilege level of 0 log in to the switch, they

can execute the tftp server-address put source-filename command (such as the tftp 192.168 .1.26 put

syslog.txt command), but cannot execute the command with the get, sget or source keyword, and

cannot specify the destination-filename argument.

• The command specified in the undo command-privilege view command can be incomplete. For

example, after the undo command-privilege view system ftp command is executed, all commands

starting with the keyword ftp (such as ftp server acl, ftp server enable, and ftp timeout) are restored

to their default level. If you have modified the level of commands ftp server enable and ftp timeout,

and you want to restore only the ftp server enable command to its default level, you should use the

undo command-privilege view system ftp server command.

• If y

ou modify the command level of a command in a specified view from the default command level

to a lower level, remember to modify the command levels of the quit command and the

corresponding command that is used to enter this view. For example, the default command level of

commands interface and system-view is 2 (system level). If you want to make the interface

command available to the level 1 users, you need to execute the following three commands:

command-privilege level 1 view shell system-view, command-privilege level 1 view system

interface GigabitEthernet 1/0/1, and command-privilege level 1 view system quit. Then, the level

1 users can enter system view, execute the interface ethernet command, and return to user view.

Examples

# Set the command level of the interface command to 0 in system view.

<Sysname> system-view

[Sysname] command-privilege level 0 view system interface

screen-length disable

Syntax

screen-length disable

undo screen-length disable

View

User view

Default level

1: Monitor level

Parameters

None

Description

Use the screen-length disable command to disable the multiple-screen output function.

Use the undo screen-length disable command to enable the multiple-screen output function.

By default, a login user uses the settings of the screen-length command. The default settings of the

screen-length command are: multiple-screen output is enabled and 24 lines are displayed on the next

screen. For more information about the screen-length command, see the chapter “Logging in to the

switch commands.”

When the user logs out, the settings restore to their default values.

Examples

# Disable multiple-screen output for the current user.

<Sysname> screen-length disable

super

Syntax

super [ level ]

View

User view

Default level

0: Visit level

10

Parameters

level: User level, which ranges from 0 to 3 and defaults to 3.

Description

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

If a level is not specified, the command switches the user privilege level to 3. Command levels include four

privileges: visit (0), monitor (1), system (2), and manage (3). You can assign a privilege level according

to the user’s need. When logging in to the switch, the user can access the assigned level and all levels

below it.

A user can switch to a lower privilege level unconditionally. A logged-in AUX or VTY user must input the

switching password set by using the super password command to switch to a higher privilege level. If the

password is incorrect or no password is configured, the switching operation fails.

Related commands: super password.

Examples

# Switch to user privilege level 2 from privilege level 3.

<Sysname> super 2

User privilege level is 2, 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 the user privilege level back to 3 (the switching password 123 has been set). If no password is

set, the user privilege level cannot be switched to 3.

<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

super authentication-mode

Syntax

super authentication-mode { local | scheme } *

undo super authentication-mode

View

System view

Default level

2: System level

Parameters

local: Authenticates a user by using the local password set with the super password command. When no

password is set by using the super password command, two results can occur: The privilege level switch

succeeds if the user is logged in through the console port. The switch fails if the user logs in through any

of the VTY user interfaces or inputs an incorrect switch password.

scheme: AAA authentication. For more information about AAA, see the Security Configuration Guide.

local scheme: First local and then scheme, which authenticates a user by using the local password first.

If no password is set for the user logged in through the console port, the privilege level switch succeeds.
