USB Port Information
Command name: /system resource usb printDescription
Shows all USB ports available for the router. Only available on the routers, supporting USB.

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 some systems, it is necessary to wait up to 30 seconds (but usually less than 10 seconds if there is no upgrade scheduled) 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] >
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
