NETWORK: AND LOCAL OPERATOR CO·MMANDS

The commands described in this section are used when the
network access method (NAM) is heing initialized or is
active. They initialize and control the 255x Network
Processing Units (NPUs), trunks, lines, terminals, and
application programs under network supervision. Initiating
NAM (refer to the NAM command in section 3) causes
NAM, the network supervisor (NS), the communications
supervisor (CS), and the network validation facility (NVF)
to be loaded and initiated at control points. NS coordinates
all of the NPUs in the· communication network. CS
coordinates the network activities of the host computer
and all of its communication elements. It establishes
logical connections between the application programs and
the terminals as they become available.
The network recognizes two types of operators: the
network operator and the local operator (neither is to be
confused with the system console operator). The network-
operator (Nap) controls network elements (NPUs, trunks,
and logical links) by communicating with NS. The local
operator (LOP) controls applications and communication
elements (lines and terminals) by communicating with CS.
The Nap and LOP can be either the system console
operator or a terminal user who is validated for the
operator privileges. A user at a single terminal can be both
types of operator at once but only one network operator
and one local operator can be declared at a time.
NAM INITIALIZATION COMMANDS
The following com·mands can be entered by the system
console operator after entering the NAM command. In
addition to these commands, the NaP/LOP commands
ENABLE, DISABLE, and RELOAD can also be entered
during initialization. Entry of the NAM command
(n.NAMffff.)" ca.lls a procedure file called NAMffff. The
system console operator can call procedure files with
different default values for configuration files and possible
inclusion of the GO command to automatically initiate
processing. If defaults are not specified in the procedure
file or are to be changed, the commands described below
can be used. They are usually entered in the order shown.
If a file containing GO is specified, these commands cannot
be entered· and the operator cannot enable or disable
elements prior to initialization.
If the network or a network program fails, use the
procedure described in appendix I on Network Failure
Processing to resume network processing.
n.CFO. NCF ,pfn,usernam,passwrd
t
Assigns the network configuration file (NCF)
specified by pfn. The NCF establishes the
configuration of NPUs, trunks, and logical links in
the network, and sets the initial state (enabled or
disabled) of those elements. The operator can
change the .state of an elem ent using the
NaP/LOP ENABLE and DISABLE commands but
subsequent entry of the NCF command cancels
the settings.
t
In this command, n is the NAM control point number.
60435600 L
n.CFO.LCF,pfn,usernam,passwrd t
Assigns the local configuration file (LCF)
specified by pfn. The LCF establishes the
applications, lines, and terminals in the network,
and sets the initial state (enabled or disabled) of
those elements. The operator can change the
state of an element using the NaP/LOP ENABLE
and DISABLE commands but subsequent entry of
the LCF command cancels the settings.
n.CFO.CCP ,pfn,usernam,passwrd t
Assigns the CCP load file specified by pfn. This
file is used to load NPUs with the CCP software.
This command can also be entered after an NPU
load to change the load file for subsequent NPU
loads.
n.CFO.GO.
t
I
Initiates processing and communication with the
network. NPUs requesting to be loaded are loaded
and configured. Configured NPUs are not
reloaded automatically at initialization but their
configuration status is recovered. NETON
requests and connections between applications are
allowed. Logical links between NPUs and the host
are established and connections between terminals
and applications are established.
BECOMING A
NETWORK/L~CAL
OPERATOR
Initially the console operator is considered both the Nap
and LOP. Once NAM has been activated, a terminal user
with the proper validation can become a Nap or LOP using
the following procedure.
1.
Log in as described in the Network Access Method
Reference Manual.
2. In response to

enter one of the following operator types.

Both local and network operator.
The system informs the console operator that he
