Hi there,
in some network segment I have a bunch of survailance cams.
If I look in the device inventory on the Fortigate (FW Version 6.4.4) about two third show
the Device Name as configured in the device. The others show just the MAC address.
We triple checked that the config is identical on all the client devices but the situation
stays just the same.
How does the fortigate retreive this device name?
Is it possible that the naming is done just once at initial detection?
How can I remove a detected device and let it be detected again?
Thanks
Ekkehard

It uses many ways to collect information about a connected device. Below is my 50e detected Macbook Air. As you can see in "src" section, the info is from arp, dns queries, http handshakes:
g50e-utm (root) # diag user device list hosts vd root/0 e0:ac:cb:5e:6c:6a gen 441 req OUA/34 created 2541268s gen 45 seen 39729s fap221b gen 388 ip 192.168.5.2 src arp hardware vendor 'Apple' src http id 540 weight 220 type 'Computer' src http id 540 weight 220 family 'MacBook \N1' src dns id 60 weight 200 os 'macOS' src http id 540 weight 220 software version '10.15.6' src http id 540 weight 220 host 'pas-MacBook-Air' src dhcp -<snip>-
Also, you can remove an entry with "del" option of this diag command.
fg50e-utm (root) # diag user device del ? <mac> MAC address (xx:xx:xx:xx:xx:xx).
