Administration Commands
define_mode
YES
SNAplus2 ignores the max_ru_size_upp and max_ru_size_low parameters, and sets the upper bound for
the maximum RU size to the largest value that can be accommodated in the link BTU size.
NO
SNAplus2 uses the max_ru_size_upp and max_ru_size_low parameters to define the maximum RU size.
max_neg_sess_lim
Maximum number of sessions allowed on this mode between any local LU and partner LU. This value can
be lowered for a particular LU-LU-mode combination when issuing
initialize_session_limit or
change_session_limit.
Specify a value in the range 0–32,767. A value of 0 indicates that SNAplus2 should not initiate implicit
CNOS exchange when an application attempts to start a session using this mode; session limits must be
specified explicitly using initialize_session_limit.
plu_mode_session_limit
Default session limit for this mode. This parameter limits the number of sessions on this mode between any
one local LU and partner LU pair. This value is used when CNOS (Change Number of Sessions) exchange
is initiated implicitly.
Specify a value in the range 0–32,767 (which must not exceed the value in max_neg_sess_lim). A value of
0 indicates that SNAplus2 should not initiate implicit CNOS exchange when an application attempts to start a
session using this mode; session limits must be specified explicitly using initialize_session_limit.
If you specify an explicit limit, the LU session limit for any LU that uses this mode must be greater than or
equal to the sum of the session limits for all modes that the LU will use.
min_conwin_src
Minimum number of contention winner sessions that a local LU using this mode can activate. This value
is used when CNOS (Change Number of Sessions) exchange is initiated either by the remote system or
implicitly by SNAplus2. Specify a value in the range 0–32,767. The sum of the min_conwin_src and
min_conloser_src parameters must not exceed plu_mode_session_limit.
cos_name
Name of the class of service (COS) to request when activating sessions on this mode. This parameter is a
type-A character string.
If the node supports mode-to-cos mapping (as defined by the mode_to_cos_map_supp parameter on the
define_node command), the COS specified by this parameter must be either an SNA-defined COS or a
COS previously defined by a define_cos command. Otherwise, you do not need to specify this parameter;
SNAplus2 ignores it.
auto_act
Specifies how many sessions to activate automatically for each pair of LUs that use this mode. This value is
used when CNOS (Change Number of Sessions) exchange is initiated implicitly.
The actual number of sessions activated is the minimum of this value and the negotiated minimum number
of contention winner sessions for the local LU.
Specify a value in the range 0–32,767.
min_conloser_src
Minimum number of contention loser sessions that can be activated by any one local LU that uses this mode.
This value is used when CNOS (Change Number of Sessions) exchange is initiated implicitly.
Specify a value in the range 0–32,767. The sum of the min_conwin_src and min_conloser_src parameters
must not exceed plu_mode_session_limit.
max_ru_size_low
