Logon mode table versus LU-mode table

Two tables are defined to VTAM® for modes:

Logon mode table: This table defines the characteristics, or capabilities, of sessions and is used by all types of LUs. Each logon mode is identified by a logon mode name.
LU-mode table: This table contains session limits. It contains the names of LUs that are possible partners and the logon mode names and their characteristics that have been defined for each LU through the APPCCMD CONTROL=OPRCNTL, QUALIFY=DEFINE macroinstruction, or the APPL definition statement, or the VTAM default, which is dynamically built. The logon mode name in the LU-mode table should match the logon name in the logon mode table. This table is specific to LU 6.2.
