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
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 system-view is 2 (system
level). To make the interface command available to the level 1 users, execute the following commands:
command-privilege level 1view 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
