>From the newsletter:

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
