To configure an LU 0 primary LU, use one of the following methods:

Motif administration program

Select LU 0 and New LU 0 primary LU from the Services menu on the Node window.

Command-line administration program

Issue the following command:
define_primary_lu0

You can use the advanced dialog to provide additional information about FM, TS, and PS profiles, transmission subsystem protocols, and user data.
