Command Reference Guide

Administration Commands
define_mode
If you use this command to modify an existing mode, the changes will apply to any new combination of local
LU and partner LU that start to use the mode after you have made the change. However, any combination of
LUs already using the mode will not pick up the changes until after the next locally or remotely initiated CNOS
command.
This command can also be used to specify the default COS to which any unrecognized modes will be mapped. If
no default COS is specified, the SNA-defined COS
#CONNECT is used.
2.41.1 Supplied Parameters
Parameter name Type Length Default
[define_mode]
mode_name character 8
description character 31 (null string)
max_ru_size_upp decimal 1024
receive_pacing_win decimal 4
default_ru_size constant YES
max_neg_sess_lim decimal 32767
plu_mode_session_limit decimal 2
min_conwin_src decimal 1
cos_name character 8 #CONNECT
auto_act decimal 0
min_conloser_src decimal 0
max_ru_size_low decimal 0
max_receive_pacing_win decimal 0
Supplied parameters are:
mode_name
Name of the mode. This name is an 8-byte type-A character string starting with a letter, or starting with # for
one of the SNA-defined modes such as #INTER. For information about SNA-defined modes, see the HP-UX
SNAplus2 Administration Guide. If the name is shorter than eight characters, spaces are added to the right to
complete the string.
To specify the default COS that will be used for any unrecognized mode names, set this parameter to a pair
of angle brackets <> (indicating an empty hexadecimal array). In this case, the cos_name parameter is taken
as the default COS name; all other parameters supplied on this command are ignored.
description
A text string describing the mode. SNAplus2 uses this string for information only. It is stored in the node’s
configuration file and returned on the query_mode_definition and query_mode commands.
max_ru_size_upp
Upper bound for the maximum size of RUs sent and received on sessions in this mode. The value is used
when the maximum RU size is negotiated during session activation.
Specify a value in the range 256–61,440. If the default_ru_size parameter is set to YES, this parameter is
ignored and the value is not checked.
receive_pacing_win
Session pacing window for sessions using this mode; specify a value in the range 1–63. This is the fixed
value for fixed pacing and the initial value for adaptive pacing. The session pacing window is the maximum
number of frames that can be received from the partner LU before the local LU must send a response.
SNAplus2 always uses adaptive pacing unless the adjacent node specifies that it is not supported.
default_ru_size
Specifies whether SNAplus2 uses the max_ru_size_upp and max_ru_size_low parameters to define the
maximum RU size. Possible values are:
135
