This issue appear as isolated to 1xx FSW series which are running firmware 7.4.8, issue 1206457 FortiSwitchOS Release Notes. The fix should be also included in 7.4.9.

Hi @funkylicious 

What is your FortiGate hardware model? I would like to reproduce the issue in my lab.
It will be a great help if my configuration and devices are as close as possible to yours. 

If possible, please share the key configurations with me via email at bhoang@fortinet.com.

Thank you
