Subsystem Functions
SCF is a software product designed to provide a common interactive management
interface for a variety of data communications products, QIO being one of them. The
system operator or network manager can use SCF commands to monitor various
objects in the QIO environment.
The interactive SCF commands supported by the QIO subsystem are presented in
Section 4, QIO Subsystem SCF Commands
, which approaches the management
functions from a task-oriented perspective. However, all the options and parameters for
each SCF command may not be described in Section 4. For complete descriptions of
all applicable SCF commands and details about using the interactive SCF interface for
QIO, see the SCF Reference Manual for G-Series RVUs.
Subsystem Functions
This subsection is a high-level view of how the QIO subsystem works. It is meant to
give you a general understanding of QIO functions to enable you to configure and
manage the QIO subsystem. Because the QIO library interface is an internal interface,
this subsection does not describe any QIO procedure calls.
