DISABLE,NETWORK
Causes immediate shutdown of network operations.
All applications must terminate immediately.
DISABLE,NPU=npu
t
or ,
DISABLE, TRUNK=trunk
t
or
DISABLE, LLINK=loglink
t
The options are as follows:
npu
trunk
Name of the Network Processing Unit.
N am e of the trunk.
loglink Name of the logical link.
The site analyst defines these element names in the
network configuration file. The DISABLE command
allows you to disable the NPU, trunk, or logical link.
If the element is active when you enter the DISABLE
command, data transmission is terminated and
affected application programs are notified.
DUMP,npu,ON
or
DUMP,npu;OFF
Sets the dump flag that indicates. whether the system
should take a memory dump of the NPU during the
next load procedure. The system does not dump the
NPU at the time you enter the command. The network
supervisor automatically sets the dump flag to ON at
the following times.
• After each successful load of the NPU.
• After the system recovers the NPU following
a deadstart recovery or a network recovery.
• At network initialization, if the previous
NAM run aborted or stopped by some means
other than the network operator command,
DISABLE, NETWORK (for example, the STOP
command).
If none of the above has occurred, during initialization
the network supervisor uses the dump flag setting in
the network configuration file.
ENABLE,NPU=npu
t
or
ENABLE, TRUNK=trunk
t
or
ENABLE,LLINK=loglink
t
The options are as follows:
npu Name of the Network Processing Unit.
trunk N am e of the trunk.
loglink Name of the logical link.
The site analyst defines these element names in the
network configuration file. The ENABLE command
allows you to ready the NPU, trunk, or logical link for
use.
Idles network operations. The system warns
applications of the upcoming shutdown.
It
rejects new
NETON requests, logins, and il1terapplication
connections and ignores newly operational NPUs. As
the applications become idle, they disconnect from the
network. When ·there are no active applications, NAM
leaves the system.
OVERLA Y ,npu,LOAD=ovl
or
OVERLAY,npu,DATA=string
or
OVERLA Y ,npu,DROP
The options are as follows:
npu Name of the Network Processing Unit.
ovl Three-character name of the NPU load
file defined during installation.
string Response to the message that the
executing overlay sent.
Usually site analysts or customer engineers use the
OVERLAY commands to take the indicated action on a
specific NPU overlay. The first form of the command
loads the specified overlay. The second form responds
to a message the overlay sent. The overlay sends a
m·essage in the following format.
FROM npu/ovl ••• string
The third form terminates overlay execution.
RELOAD,npu
or
RELOAD,npu,DUMP
Stops an active NPU, then reloads and reactivates the
NPU. If you use the second form of the command, the
system dumps the NPU before reloading it. The
system rejects this command if the· console operator
enters it during initialization or if the NPU is not
active.
STATUS, NPU=npu
or
. STATUS,TRUNK=trunk
or
STATUS, LLINK=loglink
The options are as follows:
npu Name of the Network Processing Unit.
trunk N am e of the trunk.
loglink Name of the logical link.
t
If 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. .
