Usage guidelines
To return directly to user view, you can execute the abort or return command or press Ctrl+Z.
· If you execute return or press Ctrl+Z to return from private-mode or exclusive-mode view to user view, the system displays a message to notify you of uncommitted target configuration command lines (if any).
· If you execute abort to return from private-mode or exclusive-mode view to user view, the system discards uncommitted target configuration command lines (if any) without any prompt.
Examples
# Return to user view from Ten-GigabitEthernet 3/0/1 interface view.

Parameters
alias: Specifies an alias, a case-sensitive string of 1 to 20 characters. An alias cannot be alias or contain spaces or quotation marks (").
command: Specifies a command string. Make sure the command string meets the syntax requirements.
Usage guidelines
System-defined command aliases cannot be deleted.
You can configure one or more aliases for a command or the starting keywords of commands. Then, you can use the aliases to execute the command or commands. If the command or commands have undo forms, you can also use the aliases to execute the undo command or commands.
For example, if you configure the alias shiprt for display ip routing-table, you can enter shiprt to execute the display ip routing-table command. If you configure the alias ship for display ip, you can use ship to execute all commands that start with display ip:
· Enter ship routing-table to execute the display ip routing-table command.
· Enter ship interface to execute the display ip interface command.
The command string can include up to nine parameters. Each parameter starts with the dollar sign ($) and a sequence number in the range of 1 to 9. For example, you can configure the alias shinc for the display ip $1 | include $2 command. Then, to execute the display ip routing-table | include Static command, you only need to enter shinc routing-table Static. To execute the display ip interface | include Ten-GigabitEthernet3/0/1 command, you only need to enter shinc interface Ten-GigabitEthernet3/0/1.
Examples
# Configure shiprt as the alias for the display ip routing-table command and verify the configuration.
<Sysname> system-view
[Sysname] alias shiprt display ip routing-table

Predefined user roles
network-admin
mdc-admin
Usage guidelines
Disruptive commands might power off or restart the device, interrupt services, cause service anomaly, delete key files, clear configuration, cause user login failure, or make users go offline, for example, the reboot command. Only the qualified professionals can execute disruptive commands.
As a best practice to avoid service failure due to misoperation, enable reauthentication for disruptive commands.
The following rules apply after you enable reauthentication for disruptive commands:
· For a user that can log in to the device without authentication, reauthentication is not required when the user execute disruptive commands.
· For a user that log in to the device after authentication, the user must enter the login password for authentication before disruptive commands are executed.
The undo configuration reauthentication enable command is also a disruptive command.
Examples
# Enable reauthentication for disruptive commands.
<Sysname> system-view
[Sysname] configuration reauthentication enable
# Reauthentication is required before you can execute the reboot command.
<Sysname> reboot
This command is disruptive or has significant impact on services. Please enter the login password again for reauthentication.
Password:
Start to check configuration with next startup configuration file, please wait.........DONE!
Current configuration will be lost after the reboot, save current configuration? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/startup.cfg exists, overwrite? [Y/N]:y
Validating file. Please wait...
Configuration is saved to device successfully.
This command will reboot the device. Continue? [Y/N]:y
Now rebooting, please wait...
# Reauthentication is required before you can disable reauthentication for disruptive commands.

configuration system-view-mode
Use configuration system-view-mode to specify the default mode of the system view that the system will enter after the system-view command is executed.
Use undo configuration system-view-mode to restore the default.
Syntax
configuration system-view-mode { immediate | private }
undo configuration system-view-mode
Default
The system enters real-time-mode system view after the system-view command is executed.
Views
System view
Predefined user roles
network-admin
mdc-admin
Parameters
immediate: Specifies real-time-mode system view.
private: Specifies private-mode system view.
Usage guidelines
By default, the system enters real-time-mode system view after the system-view command is executed. To configure the settings in non-real-time-mode system view, you must specify the exclusive or private keyword each time the system enters system view. To simplify the configuration, you can execute the configuration system-view-mode command to specify the default mode of the system view that the system will enter after the system-view command is executed.
The default mode of the system view that the system will enter that is specified by this command will take effect next time you execute the system-view command.
Examples
# Configure the system to enter private-mode system view after the system-view command is executed.
<Sysname> system-view
[Sysname] configuration system-view-mode private

Parameters
command: Specifies keywords. To view the available keywords, enter a question mark (?) in the place of this argument.
peer-device: Displays information for the peer member device.
with-peer-device: Appends information for the peer member device to that of the local member device. If you specify this keyword, this commands displays information for both the local and peer member devices. If you do not specify this keyword, this command displays only information for the local member device.
Usage guidelines
To view information for only the peer member device in a network configured with multichassis configuration synchronization, you can execute display command peer-device on the local device. This facilitates device management and maintenance. To view information for both member devices at the same time, execute display command with-peer-device. This is convenient for comparison between two member devices. For more information about multichassis configuration synchronization, see "Configuring multichassis configuration synchronization."

Parameters
command: Specifies the keywords and arguments of a display command. To display available keywords and arguments, enter display ?.
[ | { count | [ by-linenum ] { begin | exclude | include } regular-expression } ]&<1-128>: Specifies a maximum of 128 filter conditions.
· count: Displays the number of all lines in the command output from a display command.
· by-linenum: Numbers the output lines. You need to specify this keyword in only one filter condition.
· begin: Displays the first line matching the specified regular expression and all subsequent lines.
· exclude: Displays all lines not matching the specified regular expression.
· include: Displays all lines matching the specified regular expression.
· regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Usage guidelines
To quickly locate certain lines in the output from a display command, you can use regular expressions to filter the output, and display a number before each output line.
If a regular expression contains spaces, you can select whether to enclose the regular expression with double quotation marks, for example, display current-configuration | include interface A or display current-configuration | include "interface A".
The following rules apply when you specify regular expressions with or without double quotation marks:
· If a regular expression has double quotation marks, the string enclosed by double quotation marks is the filter condition.
· If a regular expression does not have double quotation marks, the string from the first non-space character to the last non-space character is the filter condition. The device uses this string as a filter condition for exact match of strings in the command output from a display command.
For example, regular-expression="interface A " and regular-expression=interface A are different filter conditions.
If a regular expression contains >, >, or > |, enclose the regular expression with double quotation marks (") in case the device mistake these special characters as keywords.
Strings with single quotation marks (') are not supported.
For more information about regular expressions, see Fundamentals Configuration Guide.
If you specify multiple filter conditions, the system displays the output lines that meet all the conditions.
A line number is a 5-character string and is typically followed by a colon (:). If you specify both the by-linenum and begin regular-expression options, a line number might be followed by a colon or a hyphen (-).
· Colon—The line matches the regular expression.
· Hyphen—The line does not match the regular expression.

Parameters
hotkey: Specifies a hotkey. To display the supported hotkeys, enter hotkey ? or see Table 3.
command: Specifies the command to be assigned to the hotkey.
function function: Specifies the function to be assigned to the hotkey. To display the supported functions, enter hotkey hotkey function ? or see Table 3.
none: Removes the command or function assignment for the hotkey. After you remove the assignment for a hotkey, pressing the hotkey does not execute any command or function.
Usage guidelines
The device supports a set of hotkeys. Pressing a hotkey executes the command or function assigned to the hotkey. You can configure all the hotkeys except Ctrl+].
A hotkey can correspond to only one command or function. If you assign multiple commands or functions to the same hotkey, the most recently assigned command or function takes effect.
A command or function can be assigned to multiple hotkeys. You can use any of those hotkeys to execute the command or function.
If a hotkey is also defined by the terminal software you are using to interact with the device, the terminal software definition takes effect.
Examples
# Assign the display tcp statistics command to hotkey Ctrl+T.

count times: Specifies the number of times that you want to execute the commands. The value range is 0 to 4294967295. The default is 0. If you do not specify this option, the system keeps executing the commands until you press the escape key to terminate the execution.
delay seconds: Specifies the time (in seconds) for the system to wait before executing the commands again. The value range is 0 to 4294967295. The default is 1.
Usage guidelines
To repeat a command, first enter the view for the command. To repeat multiple commands, first enter the view for the first command.
The repeat command executes commands in the order they were executed.
The system starts a timer and waits for your interaction when it repeats an interactive command. If you do not provide the required information at prompt before the timer expires, the system skips the interactive command.
The system skips all password configuration commands.

return
Use return to return to user view from any other view except Tcl configuration view and the Python shell.
Syntax
return
Views
Any view except user view, Tcl configuration view, and the Python shell
Predefined user roles
network-admin
network-operator
mdc-admin
mdc-operator
Usage guidelines
To return directly to user view from any other view except Tcl configuration view and the Python shell, use the return command. Or, you can press Ctrl+Z, which has the same effect as the return command.
To return to user view from Tcl configuration view, use the tclquit command.
To return to user view from the Python shell, use the exit() command.
Examples
# Return to user view from Ten-GigabitEthernet 3/0/1 interface view.
[Sysname-Ten-GigabitEthernet3/0/1] return
<Sysname>
screen-length disable
Use screen-length disable to disable pausing between screens of output for the current CLI session.
Use undo screen-length disable to enable pausing between screens of output for the current CLI session.
Syntax
screen-length disable
undo screen-length disable
Default
The default depends on the configuration of the screen-length command in user line view.
The following are the default settings for the screen-length command:
· Pausing between screens of output.
· Displaying up to 24 lines on a screen.
Views
User view
Predefined user roles
network-admin
mdc-admin
Usage guidelines
If you disable pausing between screens of output, all output is displayed. The screen is refreshed continuously until the final screen is displayed.
This command takes effect only for the current CLI session. When you are logged out, the default is restored.
Examples
# Disable pausing between screens of output for the current CLI session.
<Sysname> screen-length disable

system-view
Use system-view to enter system view from user view.
Syntax
system-view [ exclusive | immediate | mc-config | private ]
Views
User view
Predefined user roles
network-admin
network-operator
mdc-admin
mdc-operator
Parameters
exclusive: Specifies exclusive-mode system view.
immediate: Specifies real-time-mode system view.
private: Specifies private-mode system view.
mc-config: Specifies system view for multichassis configuration sync. If you do not this keyword, the system enters common system view.
Usage guidelines
Application scenarios
You can enter the following modes of system view:
· Common system view—In common system view and its lower-level views, settings are written to the running configuration and take effect immediately.
· Real-time-mode system view—In real-time-mode system view and its lower-level views, settings are written to the running configuration and take effect immediately.
· Non-real-time-mode system view—Includes exclusive-mode system view and private-mode system view. In exclusive-mode system view, private-mode system view, and their lower-level views, settings are saved to the target configuration, which takes effect after being committed by using the commit command.
Only one user can enter exclusive-mode system view or its lower-level views.
¡ When a user is in an exclusive-mode view, users in private-mode views cannot commit their target configuration command lines.
¡ When no user is in an exclusive-mode view, users in private-mode views can commit their respective target configuration command lines. However, only one user in a private-mode view can commit target configuration command lines at a time.
Private-mode views and exclusive-mode views have a leading tilde sign (~) in their prompts as compared to their counterpart real-time-mode views.
· System view for multichassis configuration sync—In system view for multichassis configuration sync and its lower-level views, settings that take effect on the local device are synchronized to the peer device in a network configured with multichassis configuration synchronization.
Operating mechanism
In a network configured with multichassis configuration synchronization, such as an M-LAG network, some commands must be executed on both member devices. For these commands, you have to execute them separately on the local and peer member devices. This is cumbersome and might cause configuration errors.
To resolve this issue, you can execute the system-view mc-config command to enter M-LAG-sync-mode system view. In M-LAG-sync-mode system view and its lower-level views, settings on the local M-LAG member device are synchronized to the peer member device. This ensures configuration consistency on the local and peer member devices and avoids repeated configuration. For more information about multichassis configuration synchronization, see "Configuring multichassis configuration synchronization."
Restrictions and guidelines
Unless otherwise stated, entering system view refers to entering real-time-mode system view.
Examples
# Enter system view from user view.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname]
# Enter exclusive-mode system view.
<Sysname> system-view exclusive
Info: The current configuration is locked.
~[Sysname]
# Enter system view for multichassis configuration sync from user view.
<Sysname> system-view mc-config
System View: return to User View with Ctrl+Z.
All commands in this view will be synchronized to the peer device.

terminal mmi-mode enable
Use terminal mmi-mode enable to enter machine-machine interaction (MMI) mode.
Use undo terminal mmi-mode enable to enter human-machine interaction mode.
Syntax
terminal mmi-mode enable
undo terminal mmi-mode enable
Default
The user is in human-machine interaction mode.
Views
User view
Predefined user roles
network-admin
mdc-admin
Usage guidelines
|
|
CAUTION: Do not enter MMI mode unless required. Use caution when you execute this command. |
Operating mechanism
In MMI mode, interactive commands that require confirmation by pressing Y/N, Y/N/C, or Enter in human-machine interaction mode do not require any confirmation. For example, when the reboot command is executed in human-machine interaction mode, you must press Y/N to proceed with the reboot operation. In MMI mode, the reboot operation is completed without requiring any confirmation after you execute the reboot command.
Restrictions and guidelines
· If pausing between screens of output for the current CLI session has been enabled before you enter MMI mode, all output is displayed at a time and the screen is refreshed continuously until the final screen is displayed.
· After you configure the configuration reauthentication enable command, disruptive commands that require reauthentication do not need to be confirmed again.
· Commands that require strings to be input for execution still require manual input and confirmation.
Examples
# Enter MMI mode.
<Sysname> terminal mmi-mode enable
(M)<Sysname> system-view
(M)[Sysname]
# Exit MMI mode.
(M)<Sysname> undo terminal mmi-mode enable
<Sysname>
