Another example, using minimal options, is as follows:

-> ADD TPN LLU01.LTP02
Configuring a Mode
A mode is a set of session characteristics that a group of sessions share for a particular
partner LU.
To configure a mode, the minimum specification requirements are:
•
The local mode name for the PTNR-MODE object and the mode name used for
building SNA requests (MODENAME attribute).
When the minimum requirements are specified, you also get the following defaults:
DEFAULTMAXINRUSIZE equals value of MAXINRUSIZE or 256,
DEFAULTMAXOUTRUSIZE equals value of MAXOUTRUSIZE or 256,
DEFAULTMAXSESSION 1, DEFAULTMINCONLOSER 0,
DEFAULTMINCONWINNER 1, MAXAUTOACT 0, RCVWINDOW 0, and
SENDWINDOW 0.
Optionally, you can define the following characteristics:
•
The number of sessions to be supported by that mode (DEFAULTMAXSESSION
attribute).
•
The number of sessions for which the local LU is designated to be the winner or
loser in case of contention (DEFAULTMINCONWINNER and
DEFAULTMINCONLOSER attributes). For each LU-LU session, one LU is the
contention winner of the session and the other is the contention loser of the session.
These terms relate to how contention is resolved when the two LUs attempt to
allocate a conversation at the same time.
•
The maximum size of RUs that can be sent or received by the local LU to sessions
started with this mode (DEFAULTMAXINRUSIZE and
DEFAULTMAXOUTRUSIZE attributes).
•
The number of request/response units that may be sent/received without pacing from
SNAX/APC (SENDWINDOW and RCVWINDOW attributes).
SNA-defined Mode Names
SNAX/APC can add a list of SNA-defined mode names (based on Class Of Service) to a
PTNR-LU object automatically if both the local LU and PTNR-LU have been
configured to support parallel sessions. These mode names are defined in SNA
architecture and are widely implemented in the products available on the market. If an
application is designed only to use these mode names, your network definitions can be
greatly simplified.
