Description This article explains how to correlate port counters with the various components of FortiGate NP7-based platforms.
Scope NP7 Hardware Platforms.
Solution

The 'diagnose hardware deviceinfo nic <port_number>' command in FortiOS displays port information, including descriptions, link status, and counters.
When executed on a port connected to the integrated switch fabric on an NP7 platform, these counters are sourced
from multiple components.
The following is a typical set of information recorded on a FortiGate-3501F running v7.4.8 and collected on port1 using the following command:

 

diagnose hardware deviceinfo nic port1

 

Output Description
Description: FortiASIC NP7 Adapter NPU driver name
pid: 0 A unique id for specific configuration
oid: 128 FortiGate Object Identifiers (OID) for this interface
vid: 2 Interface vlan id
macid: 0 macid is used by Fortigate to search for MAC address from MAC table
eif_id: 127 Ethernet interface id on NP7
promiscous: 0 If the interface is in promiscuous mode
vlan_wa_done: 0 vlan workaround flag
mtu: 1500 Interface MTU size
netdev oid: 128 FortiGate Object Identifiers for network device
dev-flags: 1102 A special flag indicates certain feature is turned on/off
dev-promis: 1 Network device promiscuous mode flag
Current_HWaddr: 00:09:0f:09:00:00 Network device current MAC address
Permanent_HWaddr: 80:80:2c:2c:fe:54 Interface’s permanent MAC address

Note:

The diagnose hardware deviceinfo nic <port_number> command's output (specifically the counter list) can vary slightly
between FortiOS releases. However, the organization and categorization of those counters remain consistent across
different versions.
