CLI configuration commands

In R1808P12 and later versions, the device supports the FIPS mode that complies with NIST FIPS 140-2

requirements. Support for features, commands, and parameters might differ in FIPS mode and non-FIPS

mode. For more information about FIPS mode, see Security Configuration Guide.

command-alias enable

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

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

Syntax

command-alias enable

undo command-alias enable

Default

The command keyword alias function is disabled.

Views

System view

Default command level

2: System level

Usage guidelines

Disabling the command keyword alias function does not delete the configured aliases, but the aliases do

not take effect anymore.

Examples

# Enable the command keyword alias function.

<Sysname> system-view

[Sysname] command-alias enable

# Disable the command keyword alias function.

<Sysname> system-view

[Sysname] undo command-alias enable

Related commands

command-alias mapping

Use command-alias mapping to configure a command keyword alias.

Use undo command-alias mapping to delete a command keyword alias.

Syntax

command-alias mapping cmdkey alias

undo command-alias mapping cmdkey

2

Default

A command keyword has no alias.

Views

System view

Default command level

2: System level

Parameters

cmdkey: Specifies the complete form of the first keyword of a non-undo command, or the second

keyword of an undo command.

alias: Specifies an alias for the keyword. It must be different from the first keyword of any non-undo

command.

Usage guidelines

Command keyword aliases take effect only after you enable the command keyword alias function.

Examples

# Define show as the alias of the display keyword.

<Sysname> system-view

[Sysname] command-alias mapping display show

After you configure the alias, you can enter show to execute a display command. For example, you can

enter show clock to execute the display clock command.

# Delete the alias of the display keyword.

<Sysname> system-view

[Sysname] undo command-alias mapping display

command-privilege

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

Use undo command-privilege to restore the default.

Syntax

command-privilege level level view view command

undo command-privilege view view command

Default

Each command in a view has a specified level.

Views

System view

Default command level

3: Manage level

Parameters

level level: Specifies a command level in the range of 0 to 3.

view view: Specifies a view.

3

command: Specifies a command in the specified view.

Usage guidelines

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 device, the user can access

the assigned level and all levels below it.

Improper use of this command can cause maintenance, operation, and security problems. Make sure

you understand the impact of this command on your network before you use it.

The command specified for the command-privilege command must be complete, and have valid

parameters. 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. To enable users with the privilege level 0 to execute the tftp server-address put

source-filename command (such as tftp 192.168.1.26 put syslog.txt) and disable them from specifying the

get, sget, source, or destination-filename option, configure the command-privilege level 0 view shell tftp

1.1.1.1 put a.cfg command.

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

example, configuring the undo command-privilege view system ftp command restores all commands

starting with ftp (such as ftp server acl, ftp server enable, and ftp timeout) to their default levels. 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, use the undo command-privilege view system ftp server

command.

If you change the command level of a command in a specified view from the default command level to

a lower level, you must change the command levels of the quit command and the command used to enter

this view. For example, the default command level of commands interface

and sy

stem-view is 2 (system

level). To make the interface command available to the level 1 users, execute the following commands:

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

gigabitethernet1/0/1, and command-privilege level 1 view system quit. Then, the level 1 users can

enter system view, execute the interface gigabitethernet 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

display clipboard

Syntax

display clipboard [ | { begin | exclude | include } regular-expression ]

1. Move the cursor to the starting position of the content, and then press the Esc+Shift+, combination.

2. Move the cursor to the ending position of the content, and then press the Esc+Shift+. combination.

Examples

# Display data in the clipboard.
