    I don't know where vdoms come in to your situation as you said on the subject line. But the common setup in your situation is to use a hard-switch (config sys virtual-switch) with FGxxD/E series and bind those two ports into one, so that both ports have exact same set of vlan-tagged interfaces when you configure the vlan sub-interfaces on it.

    thanks alot but could you share with an KB that related to this hard-switch (config sys virtual-switch) with FGxxD/E

     

    i asked about VDOM if there is help me or not ?

    Fortigate 81E doesnot support Aggregated.

    For anything new, look for it at the online help first:

    https://help.fortinet.com/fos50hlp/56/Content/FortiOS/fortigate-networking/Interfaces/Virtual%20Switch.htm

     

    Sounds like nothing to do with vdoms. Hard-switch would solve your problem.
