Reboot
Command name: /system rebootDescription
The system reboot is required when upgrading or installing new software packages. The packages are installed during the system shutdown.
The reboot process sends termination signal to all running processes, unmounts the file systems, and reboots the router.
Notes
Only users, which are members of groups with reboot privileges are permitted to reboot the router.
Reboot can be called from scripts, in which case it does not prompt for confirmation.
Example
[admin@MikroTik] > system reboot Reboot, yes? [y/N]: y system will reboot shortly [admin@MikroTik] >
Shutdown
Command name: /system shutdownDescription
Before turning the power off for the router, the system should be brought to halt. The shutdown process sends termination signal to all running processes, unmounts the file systems, and halts the router.
For most systems, it is necessary to wait approximately 30 seconds for a safe power down.
Notes
Only users, which are members of groups with reboot privileges are permitted to shutdown the router.
Shutdown can be called from scripts, in which case it does not prompt for confirmation.
Example
[admin@MikroTik] > system shutdown Shutdown, yes? [y/N]: y system will shutdown promptly [admin@MikroTik] >
Router Identity
Submenu level: /system identityDescription
The router identity is displayed before the command prompt. It is also used for DHCP client as 'host name' parameter when reporting it to the DHCP server.
Example
To view the router identity:
[admin@MikroTik] > system identity print
name: "MikroTik"
[admin@MikroTik] >
To set the router identity:
[admin@MikroTik] > system identity set name=Gateway [admin@Gateway] >
Date and Time
Submenu level: /system clockProperty Description
date (text) - date in format "mm/DD/YYY"dst-active (read-only: yes | no; default: no) - whether the Daylight Saving Time is currently acitve gmt-offset (read-only: text) - the current effective GMT timezone in format "+HH:MM" or "-HH:MM"time (time) - time in format "HH:MM:SS"time-zone-name (name; default: manual) - timezone code (for example, Europe/Riga or America/Chicago). Used for configuring time zone and DST adjustmentsNotes
It is recommended that you reboot the router after time change to avoid the possible inconsistencies in time measurments and logging.
Date and time settings become permanent and effect BIOS settings.
If NTP update gives time shifted by 1 hour, although the time zone is set correctly, you may want either to change the timezone, or to use manual DST control and adjust the DST delta setting in /system clock manual menu.
Example
To view the current date and time settings:
[admin@Local] system clock> print
time: 20:19:47
date: jul/13/2006
time-zone-name: "Europe/Riga"
gmt-offset: +03:00
dst-active: yes
[admin@Local] system clock>
To set the system date and time:
[admin@Local] system clock> set date=nov/22/2022 time=11:10:21 time-zone=+0
[admin@Local] system clock> print
time: 11:10:25
date: nov/22/2022
time-zone-name: "Europe/Riga"
gmt-offset: +03:00
dst-active: yes
[admin@Local] system clock>
System Clock Manual Adjustment
Submenu level: /system clock manualDescription
In most countries, a Daylight Saving Time regime is activated in spring and deactivated in autumn. This configuration menu provides DST adjustment facility, to drift the timezone according to your local legislation and practice in case it does not match any of the presets that it is possible to choose in /system clock menu from.
Property Description
dst-delta (text; default: +01:00) - UTC timezone drift in format "+HH:MM" or "-HH:MM" to be added to the local timezone during DST perioddst-end (date time) - date and time when DST ends (when the delta is to be dropped).dst-start (date time) - date and time when DST begins (when the delta is to be applied).time-zone ; default: +03:00 - GMT timezone in format "+HH:MM" or "-HH:MM"Configuration Change History
Specifications
Submenu level: /system history, /undo, /redoDescription
The history of system configuration changes is held until the next router shutdown. The invoked commands can be 'undone' (in reverse order they have been invoked). The 'undone' commands may be 'redone' (in reverse order they have been 'undone').
Command Description
/redo - undoes previous '/undo' command/system history print - print a list of last configuration changes, specifying whether the action can be undone or redone/undo - undoes previous configuration changing command (except another '/undo' command)Notes
Floating-undo actions are created within the current SAFE mode session. They are automatically converted to undoable and redoable when SAFE mode terminated successfully, and are all undone irreverively when SAFE mode terminated insuccessfully.
Undo command cannot undo commands past start of the SAFE mode.
Example
To show the list of configuration changes:
[admin@MikroTik] system history> print Flags: U - undoable, R - redoable, F - floating-undo ACTION BY POLICY U system time zone changed admin write U system time zone changed admin write U system time zone changed admin write U system identity changed admin write [admin@MikroTik] system clock>
What the /undo command does:
[admin@MikroTik] system history> print Flags: U - undoable, R - redoable, F - floating-undo ACTION BY POLICY R system time zone changed admin write U system time zone changed admin write U system time zone changed admin write U system identity changed admin write [admin@MikroTik] system clock>
System Note
Submenu level: /system noteDescription
System note feature allows you to assign arbitrary text notes or messages that will be displayed on each login right after banner. For example, you may distribute warnings between system administrators this way, or describe what does that particular router actually do. To configure system note, you may upload a plain text file named sys-note.txt on the router's FTP server, or, additionally, edit the settings in this menu
Property Description
note (text; default: "") - the noteshow-at-login (yes | no; default: yes) - whether to show system note on each loginNotes
If you want to enter or edit multiline system note, you may need to use embedded text editor: /system note edit note
