Commands; Network Element Status Codes; Network Operator Commands - Control Data Corporation CYBER 170 Series Operator's Manual

This message is followed by the prompt
•• (two consecutive periods)
and the terminal user can then perform the
operator functions described in the remainder of
this section.
To relinquish operator control, the NOP or LOP at the
terminal should enter

SYNTAX
All commands consist of a command verb and, optionally,
one or more parameters separated by a comma and/or one
or more blanks. A blank can replace a comma in the
following commands. Some commands and parameters can
be shortened to a two- or three-character abbreviation.
Allowable abbreviations are underlined in the command
format.
Parameters are order dependent and you can specify them
in one of the following formats.
keyword
I
option
keyword=option
Option is an element name, an overlay name, or a
character string. Parameter values identifying network or
communication elements are indicated by an element
name. In
all
comm'and formats, the value of element name
is a name not exceeding seven characters. The network
definition language statements define the element names.
If you are the system console operator and also the network
operator or local operator, you must enter all network and
local operator' commands using the operating system
command-from-operator (CFO) command. The format of
the command is:
n.CFO.command
n N AM control point.
command One of the network or local operator
commands. The command cannot
exceed 36 characters.
For example, you would enter
4.CFO.DISABLE, NETWORK
or
4.CFO.DI,NE
if N AM is at control point 4 and you want to disable the
network.
If you enter the CFO' command and are not the network or
local operator, the system returns the message
ILLEGAL COMMAND.
A NOP or LOP at a terminal enters only the network or
local operator command. When entered from a terminal,
the command can be more than 36 characters.
The normal system response to a command is a prompt ( •• ),
which indicates that the command has been accepted and
will
be processed. The prompt indicates readiness to
accept the next command. An abnormal system response
to a command is an informative error message followed by
the prompt. The error messages are in appendix B.
NETWORK ELEMENT STATUS CODES
Code Status
DI Disabled
EN
Enabled
Description
The
element is not active and
cannot become active unless
enabled by an operator
command.
The element is not active but
can become active during
network operations.
The following two status codes are substates of the enabled
status.
Code Status
AC Active
DN Down
Description
The element is loaded and
configured (where appropriate)
and capable of handling network
data traffic. Only enabled
elements can b~come active.
The element was active, but a
failure was detected that
terminated data traffic for the
element. If the failure
condition ceases, the element
returns to the enabled status.
If
the element is an NPU, down
status indicates that the NPU is
being dumped or loaded. The
element becomes active when
the load is complete.
NETWORK OPERATOR COMMANDS
The network operator is responsible for control of network
elements (NPUs, trunks, and logical links), loading of
overlays in NPUs, and shutdown of network operations.
tIr' entered by the system console operator during NAM initialization, this command temporarily updates the NCF and is
used only if the NPU supporting the element must be reloaded. Trunks 'cannot be enabled/disabled prior to entry of the
GO command; the action is performed after GO is entered.
