Default: 0             Value: 0-255 (except 32)

    The NSAP selector to use for CLTS when running over CLNS. If the
    value is 0 or 1, a single NSAP is shared between the Connection-
    Oriented Transport Service (COTS), and the connectionless
    transport protocol according to the osi transport attribute nsap
    selector. If both nsap selectors are 0 or 1, then COTS and CLTS
    over CLNS are disabled.

    This attribute cannot be set either to 32, which is the value
    of the NSP NSAP selector, or to the current setting of the osi
    transport attribute, nsap selector, if the attribute has a value
    other than 0 or 1.

    This attribute cannot be modified when transport is enabled.
