Defining subnetwork boundaries

The NATIVE operand on a PU definition statement specifies whether this link station represents a connection to a native node. NATIVE=NO is used when both nodes have the same network ID, but a subnetwork boundary is desired.

Consider, for example, two network nodes, SSCP1A and SSCP2A, which are defined with the same NETID, but which reside in different subnetworks. Thus, in the first sample switched major node that follows, NATIVE=NO on the PU definition statement for SW1A2A indicates that SW1A2A represents a connection to the non-native node SSCP2A. In the second sample switched major node that follows, NATIVE=NO on the PU definition statement for SW2A1A indicates that SW2A1A represents a connection to the non-native node SSCP1A.
