Hello, Recently I have upgraded 200D box from 5.0.7 to 5.2. I was using Two SSID' s . Users with bridged and Company_Guest with Tunnel for guest . But after upgrade I am not able to use the SSID and not even allowing me to delete the interface. How do I delete the interface?

    You have probably a firewall rules attached with this interface. Try to backup your configuration and search the reference to interface " Guest" and delete these references.

    You might find it easier to enable the references column on your interfaces page to get an idea of what may still be referring to that interface. Either way should help you fix the problem.

      This column is not there by default..You need to enable this from Select Columns.

      Thanks.! It doesn' t have any reference. See the below screen shots. There is only one VAP interface in VAP table.

      See if the CLI shows you anything different: diag sys checkused system.interface.name Guest

      Hi Nihas, You can try a different command, since it' s not a physical, but a wireless interface. # diagnose sys checkused wireless-controller.vap.name mesh.Speridian_Guest or # diagnose sys checkused wireless-controller.vap.name Speridian_Guest The command error message tells you on the screenshot you inserted, that you can' t delete a VAP interface under ' conf sys int' , but from the vap interface table, only. e.g # config vdom (vdom) # edit root # config wireless-controller vap (vap) # show .............. If you have no vDOMs enabled, just ignore the first 2 lines.

      Hi Thanks Yes I already tried to delete from (vap), but I can see only one vap there ,which is a working one. I cannot find the this " Guest" Tunnel anywhere on the system except interface. My requirement is I just wanted to delete this unwanted entry from the box. And I can create a new one for the Guest users. But I don;t know why this happened with 5.2..! ------------------------------------------------------------------ I executed your commands. #dia sys checkused wireless-controller.vap.name Wireless_Guest But didn' t get any out put. I think I may need re installation of 5.2 with old config backup.

      Hmmmm...So you don' t see the SSID but only the Virtual Interface. These behaviors do happen with Major releases ..waiting for FortiOS 5.2.3 before upgrading

      Hi Dipen. Yes. One SSID is working perfect without any problem , and it is a local bridged one. But second one ( Tunnel) has the problem. That one I am not able to delete.

      You will probably need " just" a factory reset (exec factoryreset) and a reload of the (clean!) config.

      No..You cannot restore a Config backup of FortiOS 5.0.7 to FortiOS 5.2. I also noticed some funny behavior for SSIDs after upgrade to FortiOS 5.2. So you are neither able to delete the SSID (virtual interface) ??
