FG-61F: "FortiSwitch Ports" does not show devices anymore in column "Device Information"
FG-61F, 6.4.5, several FortiSwitches connected via FortiLink.
Since today, the FortiSwitch Ports view does not show anymore any devices in the "Device information" column.
The "Device inventory" in the Web GUI (Dashboard, User&Devices) is empty as well.
Yet, if I check the device database with the CLI command
diag user device list
I can see that all devices are apparently still in the DB.
I like the device information in the GUI. How can I get that information back?
Interesting side info:
diag user device clear <--- seems not to work at all...
fortipg # diag user device stats
