    Hi Michaelyang , 
    the difference is "security and managerial" concerns. 
    you’re securing your virtual servers from being accessed by all vlans , so its up to you and based on your needs. 
    if you let it as default , you allow all vlans to access your virtual servers , if you specify vlans , you allow only the selected vlans to access your virtual servers.
