Description | This article describes how to troubleshoot physical issues on Fortiswitch Port. Errors will point to bad port/cable/transceiver or some physical issue. |
Scope | FortiSwitch, FortiGate. |
Solution |
Commands on FortiGate:

Look for incrementing errors and run the command over and over.
Commands on FortiSwitch:
diag switch physical-ports port-stats list (port number)
Look for incrementing errors and CRC errors and run the command over and over.
FortiGate:
diagnose switch-controller switch-info port-stats S224FSWITCH port23
Look for incrementing errors.
FortiSwitch:
diag switch physical-ports port-stats list 23
Look for incrementing errors and CRC errors.
Checking Physical layer on FortiSwitch:
diagnose switch physical-ports cable-diag <port-name>
The results can be one of the following:
Example:
