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:
