LCD Information Display Configuration

Sub-menu: /system lcd page

The submenu is used to configure LCD information display: what pages and how long they will be shown. You cannot neither add your own pages (they are created dynamically depending on the configuration) nor change pages' description.

Pages will be displayed for specified amount of time starting from the first one.

Example

To display all the pages:

[admin@MikroTik] system lcd page> print
Flags: X - disabled
  #   DISPLAY-TIME	   DESCRIPTION
  0 X 5s		   System date and time
  1 X 5s		   System resources - cpu and memory load
  2 X 5s		   System uptime
  3 X 5s		   Aggregate traffic in packets/sec
  4 X 5s		   Aggregate traffic in bits/sec
  5 X 5s		   Software version and build info
  6 X 5s		   ether1
  7 X 5s		   prism1
[admin@MikroTik] system lcd page> enable [find]
[admin@MikroTik] system lcd page> print
Flags: X - disabled
  #   DISPLAY-TIME	   DESCRIPTION
  0   5s		   System date and time
  1   5s		   System resources - cpu and memory load
  2   5s		   System uptime
  3   5s		   Aggregate traffic in packets/sec
  4   5s		   Aggregate traffic in bits/sec
  5   5s		   Software version and build info
  6   5s		   ether1
  7   5s		   prism1
[admin@MikroTik] system lcd page>

To set "System date and time" page to be displayed for 10 seconds:

[admin@MikroTik] system lcd page> set 0 display-time=10s
[admin@MikroTik] system lcd page> print
Flags: X - disabled
  #   DISPLAY-TIME	   DESCRIPTION
  0   10s		   System date and time
  1   5s		   System resources - cpu and memory load
  2   5s		   System uptime
  3   5s		   Aggregate traffic in packets/sec
  4   5s		   Aggregate traffic in bits/sec
  5   5s		   Software version and build info
  6   5s		   ether1
  7   5s		   prism1
[admin@MikroTik] system lcd page>

Troubleshooting

LCD doesn't work, cannot be enabled by the '/system lcd set enabled=yes' command.

Probably the selected serial port is used by PPP client or server, or by the serial console. Check the availability and use of the ports by examining the output of the /port print command. Alternatively, select another port for connecting the LCD, or free up the desired port by disabling the related resource

LCD doesn't work, does not show any information.

Probably none of the information display items have been enabled. Use the /system lcd page set command to enable the display.
