Overview

This subsection describes general information about SCF, which is used to configure,

control, and collect information about data communications subsystems.

SCF provides an operator interface to a process called the Subsystem Control Point

(SCP). SCP is an intermediate process between SCF and other data communications

subsystems. SCP functions as a network-management process for receiving and

redistributing the messages that SCF sends to other data communications

subsystems. SCP also provides security by restricting access to certain SCF

commands, called sensitive commands, provides version control and tracing support

for the various SCF subsystems, and supports NonStop application processes. This

interface is illustrated in Figure 4-1

on page 4-2.
