We can run cli command to a switch to detect cable faults. If the switch is cloud managed in Aruba Central we can use the GUI to test the cable.
Test Details:
- Aruba Central - AUTO-ATH-2.4.9-687-P
- 2930F switch
- AP-515
My AP is connected to port 4 of 2930F with 4 meters cable. I will check if I have cable faults using Aruba Central.
1. Under Maintenance > Tools > Device Check . Run "Cable Test" to a selected switch.

Based on the test result my cable is good and also it confirmed that it is 4 meters long. Very useful command to test layer 1.
