NCP enables an operator to perform network control functions
like changing parameters, gathering information, down-line
loading, up-line dumping, triggering bootstrap, testing link
and network, and zeroing counters.
Help for a specific command may be obtained with the HELP
command as follows:
NCP> HELP keyword [additional parameter]
For instance, if you wish additional information about the
CANCEL command you would type "HELP CANCEL"
*CANCEL
CANCEL is used to remove a command from the queue before
processing begins. You can check the status of the
command with the SHOW QUEUE command.
*CLEAR
CLEAR is used to clear parameters of an entity from the
volatile data base. Additional information available
CLEAR CIRCUIT
CLEAR EXECUTOR NODE
CLEAR LINE
CLEAR LOGGING
CLEAR NODE
*CLEAR CIRCUIT
CLEAR CIRCUIT is used to clear the volatile circuit
parameters for the circuit(s) identified in the command.
*CLEAR EXECUTOR NODE
CLEAR EXECUTOR NODE is used to reset the EXECUTOR to the
node on which the NCP program is running. Note that this
command does not return the executor to the value in the
permanent data base.
*CLEAR LINE
CLEAR LINE is used to clear the volatile line parameters
for the line(s) identified in the command.
*CLEAR LOGGING
CLEAR LOGGING is used to control the logging of events,
both the events that will be logged and where they will
be logged.
*CLEAR NODE
CLEAR NODE is used to clear the volatile parameters of
the node identified as node-id or set as EXECUTOR.
*DEFINE
DEFINE is used to modify values in the permanent data
base of the identified entity. Additional information
available
DEFINE CIRCUIT
DEFINE LINE
DEFINE LOGGING
DEFINE NODE
*DEFINE CIRCUIT
DEFINE CIRCUIT is used to set the permanent circuit
parameters for the circuit(s) identified in the command.
*DEFINE LINE
DEFINE LINE is used to set the permanent line parameters
for the line(s) identified in the command.
*DEFINE LOGGING
DEFINE LOGGING is used to control where the events are
logged (event sinks) and which events get logged.
*DEFINE NODE
DEFINE NODE is used to set the permanent parameters for
the node identified as node-id or set as EXECUTOR.
*DUMP
DUMP is used to store a copy of the target's memory image
in a dump file at the host node.
*ENTER
ENTER is used to enter an alternative command processor
for an application type.
*EXIT
EXIT is used to leave NCP command level and return to the
TOPS-20 monitor command level.
*HELP
HELP allows you to display the function and format of any
NCP command. The format is
NCP> HELP keyword [additional parameters]
where keyword can be any one of the following NCP
commands:
CANCEL CLEAR DEFINE DUMP ENTER EXIT HELP
LIST LOAD LOOP PURGE PUSH RETURN SET
SHOW TAKE TELL TRIGGER ZERO
*LIST
LIST is used to display information from the permanent
data base.
*LOAD
LOAD is used to load the system image file from one node
to a remote node in the network
*LOOP
LOOP is used to request a node level loopback test. The
node specified in the command is the node to be connected
TO; that is, the node that will loop back the data.
This may be the local node or a remote node.
*PURGE
PURGE is used to clear parameters of an entity from the
permanent data base. Additional information available
PURGE CIRCUIT
PURGE EXECUTOR NODE
PURGE LINE
PURGE LOGGING
PURGE NODE
*PURGE CIRCUIT
PURGE CIRCUIT is used to clear the permanent circuit
parameters for the circuit(s) identified in the command.
*PURGE EXECUTOR NODE
PURGE EXECUTOR NODE is used to reset the executor in the
permanent data base to the local node.
*PURGE LINE
PURGE LINE is used to clear the permanent line parameters
for the line(s) identified in the command.
*PURGE LOGGING
PURGE LOGGING is used to control the logging of events,
both the events that will be logged and where they will
be logged.
*PURGE NODE
PURGE NODE is used to clear the permanent parameters of
the node identified as node-id or set as EXECUTOR.
*PUSH
PUSH is used to leave the NCP command level and enter the
TOPS-20 monitor command level. The POP command is used
to return to the NCP command level.
*RETURN
RETURN is used to return to the OPR command level.
*SET
SET is used to modify values in the volatile data base of
the identified entity. Additional information available
SET CIRCUIT
SET LINE
SET LOGGING
SET NODE
*SET CIRCUIT
SET CIRCUIT is used to set the volatile circuit
parameters for the circuit(s) identified in the command.
*SET LINE
SET LINE is used to set the volatile line parameters for
the line(s) identified in the command.
*SET LOGGING
SET LOGGING is used to control where the events are
logged (event sinds) and which events get logged.
*SET NODE
SET NODE is used to set the volatile parameters for the
node identified as node-id or set as EXECUTOR.
*SHOW
SHOW is used to display information from the volatile
data base.
*TAKE
TAKE is used to execute a series of NCP commands from a
specified command file.
*TELL
TELL NODE is used as a prefix to designate the node that
is to process the command. The prefix is effective only
for the single command that immediately follows.
Although the access information is optional, the node
specified as node-id may refuse to accept the command.
Using the TELL NODE prefix is more efficient than a
combination of SET EXECUTOR and CLEAR EXECUTOR commands
when only one command is to be given to a node.
*TRIGGER
TRIGGER is used to attempt to cause the target node (the
node to be loaded) to send a load request to the
executor. If the load request is sent successfully, the
load proceeds automatically.
*ZERO
ZERO is used to generate a counters zeroed event that
causes counters to be logged. The counters are then set
to zero. The counters affected are those associated with
the specified entity.
