/LARGE_BUFFER
       /NOLARGE_BUFFER

    Allows you to control whether the LAT software uses large buffers
    while managing communications between OpenVMS systems (the
    default).

    If you must use the /NOLARGE_BUFFER qualifier (for example, to
    limit packet sizes to be no larger than the Ethernet maximum),
    VSI recommends that you specify this command after all
    logical LAT links have been created and before the LAT node
    has been turned on. For example, note following commands in
    LAT$SYSTARTUP.COM:

     $!
     $! Create each logical LAT link with a unique name and
     $! unique LAN address (forced with /NODECNET).
     $!
     $ LCP CREATE LINK FDDI_1 /DEVICE=FCA0 /NODECNET
     $ LCP CREATE LINK FDDI_2 /DEVICE=FCB0 /NODECNET
     $!
     $! Don't use large buffer support (force packet
     $! sizes to be no larger than what Ethernet can
     $! support).
     $!
     $ LCP SET NODE /NOLARGE_BUFFER
     $!
     $! Turn on the LAT protocol.
     $!
     $ LCP SET NODE /STATE=ON
