Both visualizations can be filtered to show four main views: device traffic, device count, device type, or no devices. Finally, like other FortiView pages, the topology can be filtered by time.
Physical Topology shows the devices in the security fabric and which devices are connected. You can select whether or not to view access layer devices in this topology.
Logical Topology displays information about network interface (logical or physical) and which interfaces are used to connect devices in the fabric.
