[/Transport]
        Configures settings used by transport server (when you install
        only the Transport Server role service).

  [/ObtainIpv4From:{Dhcp | Range}]
        Specifies the source of IPv4 addresses.

    [/Start:]
        Specifies the start of the IP address range. This is required
        if /ObtainIpv4 is set to Range.

    [/End:]
        Specifies the end of the IP address range. This is required if
        /ObtainIpv4From is set to Range.

  [/ObtainIpv6From:Range]
        Specifies the source of IPv6 addresses. The only supported
        value is Range.

    [/Start:]
        Specifies the start of the IP address range. This is required
        when /ObtainIpv6From is set to Range.

    [/End:]
        Specifies the end of the IP address range. This is required
        when /ObtainIpv6From is set to Range.

  [/PortPolicy:{Dynamic | Fixed}]
        Specifies the UDP port policy to use.  Set this to Dynamic for
        obtaining ports dynamically from Winsock.  Set this to Fixed
        for using ports from a fixed range.

  [/StartPort:]
        Specifies the start of the port range.

    [/EndPort:]
        Specifies the end of the port range.  This is required when
        /PortPolicy is set to Fixed.

  [/Profile:{10Mbps | 100Mbps | 1Gbps | Custom}]
        Specifies the network profile to use.  Note: This option is
        only available for servers running Windows Server 2008 or
        Windows Server 2003.

  [/MulticastSessionPolicy]
        Configures transfer settings for multicast transmissions.

    [/Policy:{None | AutoDisconnect | Multistream}]
        Determines how to handle slow clients.  None means to keep all
        clients in one session at the same speed.  AutoDisconnect
        means that any clients that drop below the specified
        /Threshold will be disconnected.  Multistream means clients
        will be separated into multiple sessions as specified by
        /StreamCount.

    [/Threshold:]
        For /Policy:AutoDisconnect, this option sets the minimum
        transfer rate in KBps.Clients that drop below this rate will
        be disconnected from multicast transmissions.

    [/StreamCount:{2 | 3}]
        For /Policy:Multistream, this option determines the number of
        sessions.  2 means two sessions (fast and slow) 3 means three
        sessions (slow, medium, fast).

    [/Fallback:{Yes | No}]
        Determines whether clients that are disconnected will continue
        the transfer using another method (if supported by the
        client). If you are using the WDS client, the computer will
        fallback to unicasting.  Wdsmcast.exe does not support a
        fallback mechanism. This option also applies to clients that
        do not support Multistream. In that case, the computer will
        fall back to another method instead of moving to a slower
        transfer session.

  [/TftpMaximumBlockSize:]
        Specifies the maximum block size that the TFTP server can use.

  [/EnableTftpVariableWindowExtension:{Yes | No}]
        Specifies if the TFTP variable window extension is enabled.
