General information


Setting the System's Identity provides a unique identifying name for when the system identifies itself to other routers in the network and when accessing services such as DHCP, Neighbour Discovery and default wireless SSID. The default system Identity is set to MikroTik. System Identity has a 64 maximum character length.

[admin@MikroTik] > system/identity/set name=mygateway


The /system note feature allows you to assign arbitrary text notes or messages that will be displayed on each login right after the 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 through the CLI:

[admin@MikroTik] > system note set note="\n You are logged in the gateway router. Be careful with the configuration!"

Now open a new terminal:

  MMM      MMM       KKK                          TTTTTTTTTTT      KKK
  MMMM    MMMM       KKK                          TTTTTTTTTTT      KKK

It is also possible to change the router system identity by SNMP set command:

snmpset -c public -v 1 s New_Identity
  • snmpset - Linux based SNMP application used for SNMP SET requests to set information on a network entity;
  • public - router's community name;
  • - IP address of the router;
  • - SNMP value for router's identity;




The general resource menu shows overall resource usage and router statistics like uptime, memory usage, disk usage, version, etc.

[admin@MikroTik] > system resource print
             uptime: 25m12s

Hardware Attachments


LCDs mainly are used to display system information, but LCDs also allows you to do the following:

  • Reboot the device;
  • Reset units configuration;
  • add IP address;
  • disable interface;

For example, if we want to see statistical information on the LCD, we will configure the following:

[admin@MikroTik] > /lcd/show screen=stat-slideshow

Let's take a look at what does the unit shows at the LCD information. The device allows you to capture a screenshot:

[admin@MikroTik] > /lcd/take-screenshot file-name=stat-screenshot
Screenshot taken

Under the /file section you will find the following image captured from the LD:

RouterOS allows you to change various LCD parameters:

  • set an LCD PIN code for the safety;
  • change color scheme;
  • set timeout interval;
  • flip screen;
  • disable it;
  • enable read-only mode;
[admin@MikroTik] > /lcd/print 
            enabled: yes
       touch-screen: enabled
  backlight-timeout: 30m
     read-only-mode: no
      time-interval: min
     default-screen: main-menu
       color-scheme: light
        flip-screen: no

PIN code number allows to protect sensitive menus on the LCD screen. The PIN number will be asked if Read-Only mode is disabled and you add an IP address, reset or reboot the router. Default PIN is 1234

RouterOS allows to configure each LEDs activity the way that user wishes. It is possible to configure the LEDs to display wireless strength, blink the LEDs on interface traffic activity and many other options.

For example default led configuration on CCR1009-7G-1C-1S+:

[admin@MikroTik] > system/leds/pr
Flags: * - default
#     TYPE                INTERFACE     LEDS             
0  *  interface-speed     sfp-sfpplus1  sfp-sfpplus1-led1
1  *  interface-activity  sfp-sfpplus1  sfp-sfpplus1-led2
2  *  interface-activity  combo1        combo1-led     

The listed devices support turning off their LEDs (LED dark mode), however some LEDs still cannot be turned off due to the device design factors.

Modem Signal Strength example

The whole modem-signal strength range is [-113..-51] and the modem-signal-threshold increases the weakest signal limit to -91 so the signal range for the LED indication is [-91..-51]. That range is divided into equal parts depending on the number of LEDs configured for modem-signal LED triggers. The first LED turns on when the signal is above -91 and the last LED turns on when the signal reaches -51.

/system leds
add interface=lte1 leds=led1,led2,led3,led4,led5 modem-signal-treshold=-91 type=modem-signal

Modem Access Technology example

These LED trigger examples turn on LEDs in order of modem technology generation: GSM; 3G; LTE.

1 LED: led1 turns on when LTE is active:

/system leds
add interface=lte1 leds=led1 modem-type=modem-technology

2 LEDs: led1 - 3G; led2 - LTE;

/system leds
add interface=lte1 leds=led1,led2 modem-type=modem-technology

3 LEDs: led1 - GSM; led2 - 3G; led3 - LTE

/system leds
add interface=lte1 leds=led1,led2,led3 modem-type=modem-technology


The UPS monitor feature works with APC UPS units that support “smart” signalling over serial RS232 or USB connection. The UPS monitor service is not included in the default set of packages so it needs to be downloaded and installed manually with ups.npk package. This feature enables the network administrator to monitor the UPS and set the router to ‘gracefully’ handle any power outage with no corruption or damage to the router. The basic purpose of this feature is to ensure that the router will come back online after an extended power failure. To do this, the router will monitor the UPS and set itself to hibernate mode when the utility power is down and the UPS battery has less than 10% of its battery power left. The router will then continue to monitor the UPS (while in hibernate mode) and then restart itself when the utility power returns. If the UPS battery is drained and the router loses all power, the router will power back to full operation when the ‘utility’ power returns.

The UPS monitor feature on the MikroTik RouterOS supports

  • hibernate and safe reboot on power and battery failure
  • UPS battery test and run-time calibration test
  • monitoring of all "smart" mode status information supported by UPS
  • logging of power changes

Connecting the UPS unit

The serial APC UPS (BackUPS Pro or SmartUPS) requires a special serial cable (unless connected with USB). If no cable came with the UPS, a cable may be ordered from APC or one can be made "in-house". Use the following diagram:

Router Side (DB9f)SignalDirectionUPS Side (DB9m)

If using a RouterBOARD device, make sure to set your "RouterBOOT setup key" to Delete instead of the default Any key. This is to avoid the accidental opening of the setup menu if the UPS unit sends some data to the serial port during the RouterBOARD startup. This can be done in the RouterBOOT options during boot time or via the RouterBoard Settings in Winbox :

Select key which will enter setup on boot:
 * 1 - any key
   2 - <Delete> key only
your choice:

Runtime Calibration

The rtc command causes the UPS to start a run time calibration until less than 25% of full battery capacity is reached. This command calibrates the returned run time value.

/system ups rtc <id>

The test begins only if the battery capacity is 100%.

Quick Example

To enable the UPS monitor for port serial1:

[admin@MikroTik] system ups> add port=serial1 disabled=no
