Description

Solution

Below are the logs and outputs to collect for device detection issues, such as when device details are incorrectly identified or the FortiGate is unable to detect the device details, before opening a TAC ticket.

get system status

show full | grep device-detection

diagnose autoupdate versions | grep -A 7 "Mac Addr"

diagnose user device get <MAC Address of device>

diagnose vendor-mac match <MAC Address of device>
diagnose user device list
diagnose cid stats
diagnose debug crashlog read

Additionally, collect the below debug while connecting the device to the network:

For v7.4:

diagnose debug reset

diagnose cid debug filter mac <MAC Address of device>

diagnose cid debug start    

diagnose cid debug stop

For v7.2:

diagnose debug reset

diagnose debug application cid -1

diagnose debug enable

For v7.0:

diagnose debug enable

To stop the debug processes in the end, press 'Ctrl+C' and enter 'diagnose debug disable'.
