- 'Device_1' is directly connected to the FortiGate interface: 'port16'.
- 'VLAN Switch / hard-switch' configuration:
- Interface 'lan' configuration:
- Virtual MAC Address to interface 'lan':
- MAC Address to interface 'port16':
- MAC Address to 'Device_1': 'e8:1c:ba:a7:e9:fd'.
When 'VLAN Switch / hard-switch' is configured in FortiGate. - FortiGate learns 'Device_1' MAC Address by 'lan' interface:
- Due to interface 'lan' having 'device-identification' enabled its possible to filter by 'Device_1' MAC Address:
- Event 'Device_1' is connected directly to interface 'port16' all traffic statistics will be displayed on interface 'lan'.
- MAC Address Negotiation will be between the 'Device_1' MAC Address Physical interface and the Virtual MAC Address 'lan' interface.
