Hi all

I have noticed a weird issue, client had a power outage over the weekend as the redid the server room UPS.

Now my AP’s show “Connected VIA” my VOIP interface on the FortiGate, even tough they are connected via FortiSwitches and the LLDP Neighbors are correct, also the IP’s they get are from my DATA VLAN.

They use to say connected via DATA VLAN and once rebooted they now show VOIP. all troubleshooting points to they are indeed connect via DATA VLAN.

GUI BUG? FortiGate 7.4.12 , FortiSwitches 7.4.8 and FortiAP’s 7.4.6

Please let me know if anyone has experienced this and why now all of the sudden?

Hi Fabrichound

According to your description this is likely a GUI bug.

Hi AEK

I do think it is, but I have similar hardware and Firmware version on other sites, but only the 1 is doing it at the moment.

Hence it is a bit of a weird one

Hi

I understand. Actually a bug is not only related to hardware and firmware, it can also be related to configuration, load, used features, and other context conditions.

This is most likely a GUI display/caching issue rather than an actual connectivity problem.

Can you share the snapshot of the issue.

Thanks, Salon

Thanks, I have investigated it further and everything points to a GUI bug, it shows it is connected via a software switch on the FortiGate where the VOIP is, but it is physically connect on my FortiSwitch and has Native VLAN DATA. but check all settings in CLI and LLDP neighbors and it is correct in the CLI.

Thanks for all the feedback, hoping it gets fixed in the updates

Hi @Fabrichound

Thank you for the information. After using the Fortinet Support Tool to capture the GUI and CLI logs, we will investigate the outputs. If the issue does not match any known bug, I will attempt to reproduce it in my lab and then escalate it to our Engineering team for further investigation and a permanent fix.

Thank you.

This issue does seem to match a known GUI display defect in 7.4.12. As other have mentioned in the thread, output from Fortinet Support Tool would help confirm, thanks.
