[ametkola]

Description	This article describes the behavior of not showing any information under 'Device Information' after a firmware upgrade.
Scope	FortiOS v7.4.5
Solution	Device information is empty and is not possible to see what device is connected to which switch port on the FortiSwitch. This behavior impacts several devices once are upgraded to firmware version 7.4.4 and 7.4.5 When checking under WiFi & Switch Controller -> FortiSwitch Ports.   In addition, the connection status between the FortiGate and FortiSwitch shows as follows: execute switch-controller get-conn-status P3-DITC-5 v7.4.2 (801) Authorized/Up 2E 169.254.1.8 Tue Nov 21 18:26:24 2024 XXXXXXXXXXXX Lastly, the following debug outputs will display entries similar to the following: diagnose debug application flcfgd -1 diagnose debug console timestamp enable diagnose debug enable 740us flcfg_proc_terminated_child[579]:found pid(1642) to msw(0 switch_a) mapping 781us flcfg_proc_terminated_child[642]:config failure for (0, switch_a) type(0x2) resch(0) The above debug outputs indicate a connection problem between FortiGate and FortiSwitch. Apply the following workaround to solve this issue: config switch-controller system     set tunnel-mode compatible     next end Compatible: Least restrictive. Supports the widest variety of hardware and software versions. Moderate: Moderate level of security. Supports recent generations of hardware and latest software versions. Strict: The highest level of security. Supports only the latest generation of hardware and latest software version. Related document: config switch-controller managed-switch
