Cable diagnostic:
In RouterOS v5.21 and newer releases we have added a wonderful new diagnostics feature - ability to detect cable problems. For example, if you have an apartment building with complicated Ethernet wiring inside the walls or ceilings, and you lose the link - previously, you would need special equipment to pinpoint the location of
cable damage, before you open that wall, but now - RouterOS will tell you these things:
• which cable pair is damaged
• at what length is the cable broken
• how is the cable broken - shorted or torn
This also works if the other end is simply unplugged - in that case, simply the cable lenght will be shown.
This works on SXT-G, RB711G, RB2011, RB750 series and other devices with the same switch chips, and also the Cloud Core series devices.
Here is example output:
[admin@CCR] > interface ethernet monitor ether5
status: no-link
auto-negotiation: done
cable-pairs: open:4,open:4,open:4,open:4
In the above example, cable is not shorted but cut “open” at 4 meters lenght, all cable pairs equally at same location
