You can enable device detection to allow FortiOS to monitor your networks and gather information about devices operating on those networks, including:
- MAC address
- IP address
- Operating system
- When FortiOS detected the device and on which interface
You can view the devices in User & Device > Device Inventory. You can assign each device an alias for easy identification. If you do not assign an alias to a device, Device Inventory displays the device's MAC address.
You can enable device detection separately on each interface in Network > Interfaces. Device detection is intended for devices directly connected to your LAN ports. If enabled on a WAN port, device detection may be unable to determine the OS on some devices. You can enable active scanning on the interface to find hosts whose device types FortiOS cannot determine passively.
You can also manually add devices to Device Inventory to ensure that a device with multiple interfaces displays as a single device. See Creating a custom device.
To assign an alias to a device:
- Go to User & Device > Device Inventory.
- Edit the desired device.
- Enter the desired alias.
- Click OK.
Device Inventory categorizes devices. You can categorize a device using the CLI:
config user device
set category [none | android-device | blackberry-device | fortinet-device | ios-device | windows-device]
