NOF API Verbs (ACTIVATE_SESSION to OPEN_FILE)
DEFINE_MODE
Chapter 3 313
DEFINE_MODE
The DEFINE_MODE verb defines a mode (a set of networking
characteristics to be used by a group of sessions) or modifies a previously
defined mode. You cannot modify the SNA-defined mode CPSVCMG or
change the COS name used by the SNA-defined mode SNASVCMG.
If you use this verb 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 verb 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.
