Explanation
The FortiGate command diagnose hardware deviceinfo nic provides hardware-level network interface card (NIC) details, including its physical MAC address and error/collision statistics.
Common mistakes.
- A. The ARP cache, which maps IP addresses to MAC addresses, is a network layer function and is viewed using commands like
get system arpordiagnose ip arp list, not a direct hardware attribute reported bydeviceinfo nic. - D. Listening TCP ports indicate services and applications running on the FortiGate's operating system, not a hardware characteristic of the NIC itself; this information is typically retrieved using
fnsysctl netstat -apn.
