Displaying detail Hardware NIC information

Monitoring the hardware NIC is important because interface errors indicate data link or physical layer issues which may impact the performance of the FortiGate.

To monitor hardware network operations in the CLI:

diagnose hardware deviceinfo nic <interface>

Sample output:

The following is sample output when the <interface> is set to lan:
