Cannot delete Aggregate Interface also software switch Interface

Hi all,

I have a trouble with my fortigate 1500D

I configure it via my web console on my laptop. I create an aggregate port with members: port22 and port 24, I named that port DMZ2.

After that, on other laptop, I use web console to delete above aggregate interface and then I create a software switch with members: port22 and port24, I also use name port DMZ2

When I comeback to my laptop, I refresh web console, it show that port A is aggregate port and no members in it.

I cannot delete port DMZ2. I click Delete, it ask me "Are you sure you want to delete this entry", I click OK but it does not work.

I use cli to show and result below:

DSVN-fortigate1500D # show system interface DMZ2 config system interface     edit "DMZ2"         set vdom "root"         set type aggregate         set snmp-index 52     next end DSVN-fortigate1500D # show system switch-interface config system switch-interface     edit "DMZ2"         set vdom "root"         set member "port22" "port24"     next end

As the result of show, DMZ2 is an aggregate port with no member and also is switch port with two members port22 and port24.

DSVN-fortigate1500D # show system interface port22 config system interface     edit "port22"         set vdom "root"         set type physical         set snmp-index 24     next endDSVN-fortigate1500D # show system interface port24 config system interface     edit "port24"         set vdom "root"         set type physical         set snmp-index 26     next end but port22 and port24 still are physical port.

I create new software switch but port22 and port24 is not availability to choose.

Please help me!!!

Thanks and best regards!
