Applies to RouterOS: v5 +


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 Groove

[admin@MikroTik] /system leds> print 
Flags: X - disabled 
 #   TYPE                     INTERFACE                   LEDS                 
 0   wireless-signal-strength                             led1                 
 1   interface-activity       ether1                      user-led     

RB Groove uses five leds for wireless strength and one for ethernet activity monitoring.


Sub-menu: /system leds

Property Description
disabled (yes | no; Default: no) Whether item is disabled
interface (string; Default: ) Name of the interface which will be used for led status. Applicable only if type is interface specific.
modem-signal-treshold (integer [-113..-51]; Default: ) Applicable if type is modem-signal
leds (list of leds; Default: ) List of led names used for status report. For example wireless signal strength will require more than one led.
type (align-down | align-left | align-right | align-up | ap-cap | fan-fault | flash-access | interface-activity | interface-receive | interface-speed | interface-speed-1G | interface-speed-25G | interface-status | interface-transmit | modem-signal | modem-technology | off | on | poe-fault | poe-out | wireless-signal-strength | wireless-status; Default: ) Type of the status:
  • align-down - light the led if the w60g device needs to be aligned downwards for the best signal quality
  • align-left - light the led if the w60g device needs to be aligned to the left
  • align-right - light the led if the w60g device needs to be aligned to the right
  • align-up - light the led if the w60g device needs to be aligned upwards
  • ap-cap - blink on CAP initializing with CAPsMAN, steady on once connected
  • fan-fault - light the led when any of the device controlled fans stop working
  • flash-access - blink the led on flash access
  • interface-activity - blink the led on interface (traffic) activity
  • interface-receive - blink the led on interface received traffic
  • interface-speed - light the led when interface works in 10Gbit rate
  • interface-speed-1G - light the led when interface works in 1Gbit rate
  • interface-speed-25G - light the led when interface works in 25Gbit rate
  • interface-status - light the led on interface status change
  • interface-transmit - blink the led on interface transmitted traffic
  • modem-signal - blink the led on 3G modem signal (either USB or miniPCIe)
  • modem-technology - turns on leds in order of modem technology generation: GSM; 3G; LTE; single led turns on only when LTE is active.
  • off - turn off the led
  • on - turn on the led
  • poe-fault - light the led when PoE out budget is close to the maximum supported limit
  • poe-out - light the led when interface PoE out turns on
  • wireless-signal-strength - light the leds displaying wireless signal (requires more than one led)
  • wireless-status - light the led on wireless status change.

Leds Setting

Global settings are stored in Leds Setting menu.

Sub-menu: /system leds setting

Property Description
all-leds-off (after-1h | after-1min | immediate | never; Default: never) Whether and when all leds of router can be turned off

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.

Indoor devices

RBLDFG-5acD (LDF 5 ac) Turns off all LEDs except Ethernet LED

Basic example

Led control via CLI commands for scripting purposes:

  • prior to v6.23 and older releases:
#turn led on
:led led1=yes
#turn led off
:led led1=no
  • v6.23 and newer releases:
#add led entry with specific type "on" or "off" to leds menu
/system leds add leds=led1 type=off
#to control led
/system leds set [find where leds="led1"] type=on
/system leds set [find where leds="led1"] type=off

Enable the User ACT LED to show current CAP status on a RB951

/system leds
add leds=user-led type=ap-cap

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 LED indication is [-91..-51]. That range is divided into equal parts depending on number of LEDs configured for modem-signal LED trigger. The first LED turns on when signal is above -91 and the last LED turns on when 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
