CLI Commands
command-alias enable
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, which means you cannot configure command aliases.
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
command-alias mapping cmdkey alias
undo command-alias mapping cmdkey
View
System view
Default Level
2: System level
Parameters
cmdkey: The complete form of the first keyword of a command for which an alias will be configured.
alias: Specifies the command alias, which cannot be the same with 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 the above configuration, the display commands have their 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. The value shell of the argument view represents user view. The specified view must be the view to which the command provided by the command argument belongs; for the corresponding view, see the "View" section of the specified command.
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 its specified level. For more information, see Basic System Configuration in the Fundamentals Command Reference. Command level falls into four levels: visit, monitor, system, and manage, which are identified by 0 through 3. The administrator can assign a privilege level for a user according to his need. When the user logs on a device, the commands available depend on the user’s privilege. For example, if a user’s privilege is 3 and the command privilege of VTY 0 user interface is 1, and the user logs on the system from VTY 0, he can use all the commands with privilege smaller than three (inclusive).
l Use the default command level or modify the command level under the guidance of professional staff; otherwise, the change of command level may bring inconvenience to your maintenance and operation, or even potential security problem.
l When you configure the command-privilege command, the value of the command argument must be a complete form of the specified command, that is, you must enter all needed keywords and arguments of the command. The argument should be in the value range. 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 device, they can execute the tftp server-address put source-filename command (such as the tftp 192.168.1.26 put syslog.txt command); users with the user privilege level of 0 cannot execute the command with the get, sget or source keyword, and cannot specify the destination-filename argument.
l When you configure the undo command-privilege view command, the value of the command argument can be an abbreviated form of the specified command, that is, you only need to enter the keywords at the beginning of the command. 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) will be restored to the default level; if you have modified the command 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.
l If you 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 users with the user privilege level of 1, you need to execute the following three commands: command-privilege level 1 view shell system-view, command-privilege level 1 view system interface ethernet 1/1, and command-privilege level 1 view system quit, so that the login users with the user privilege level of 1 can enter system view, execute the interface ethernet command, and then return to user view.
Examples
# Set the command level of the system-view command in user view to 3. (By default, users with the user privilege level of 2 or 3 can use the system-view command after login; after the following configuration, only users with the user privilege level of 3 can use this command to enter system view and configure the device. Therefore, the device security is improved.)
