That depends on the network card, driver and network stack. Windows is notorious for not showing VLAN info. See http://wiki.wireshark.org/CaptureSetup/VLAN

    A common cause of this seems to be when you have 802.1q VLAN tags
    coming into the machine and being passed up into Wireshark.  If this
    is the case, you would need to use "vlan and <your filter>".
