The value indicates how the Node should be activated for the first time. The values have the following meanings: other (1) - may be used for proprietary methods not listed in this enumeration, startup (2) - at SNA services' initialization time (this is the default), demand (3) - only when LU is requested by application, or onlyMS (4) - by a Management Station only. A write operation to this object may immediately change the operational value reflected in snaNodeOperEnablingMethod depending on the Agent implementation. If the Agent implementation accepts immediate changes, then the behavior of the Node changes immediately and not only after the next system startup of the SNA services. An immediate change may only apply when the current value 'demand (3)' is changed to 'onlyMS (4)' and vice versa.
