Accessing the WAN Subsystem
When issuing a command, you specify the subsystem in the line name (for example,
$ZZWAN.#X25P1). SCP then routes the command to the correct subsystem (in this
example, the WAN Manager).
SCF commands manipulate objects. An X25AM I/O process is called an X25AM
DEVICE object in the WAN subsystem; the line that the X25AM I/O process controls is
an X25AM LINE object in the X25AM subsystem. Thus, the SCF command to
configure an I/O process is the ADD DEVICE command; the SCF command to start an
X25AM line is the START LINE command.
Required Modifiers for the ADD DEVICE Command
Some modifiers are required in the SCF ADD DEVICE command to the WAN
subsystem; others are optional. The following modifiers are required to configure an
X25AM I/O process:
•
ADAPTER, CLIP, LINE
•
CPU, ALTCPU
•
IOPOBJECT
•
PROFILE
•
RECSIZE
•
TYPE (must be 61), SUBTYPE (must be 63)
RECSIZE can be set to any 16-bit integer value (1 through 32767); the value does not
affect the maximum record size that you specify for any subdevice on the line
controlled by the I/O process. For information about these modifiers, see the WAN
Subsystem Configuration and Management Manual.
Required Attributes for the ADD SU Command
Some attributes are required in the SCF ADD SU command to the X25AM subsystem;
others are optional. The following attributes are required to configure an X25AM
subdevice on a line:
•
DEVTYPE
•
PROTOCOL
•
RECSIZE
For information about these modifiers, see Section 5, Attribute Descriptions.
Note. PATH is optional; if not specified, PATH A is the default.
