Cable Testing
This is a diagnostic and troubleshooting tool to check the state of cables between the FortiSwitch and the devices connected to its physical ports. This tool does not work on fiber ports and on very short or very long cables (more than 100 meters).
All available external physical ports of the FortiSwitch are displayed. Select one or more ports and click Diagnose.
Note: Running the cable diagnostic test on a port disables it briefly. The network traffic is affected for a few seconds.
