instead relies exclusively on access control
information supplied in the connect requests
to validate the logical link.
ENABLED: Invokes the appropriate proxy, based on
the source user, source node, and supplied
access control information (if any).
TIMER
Defines the maximum duration between the time a connection is received for a process and the time that process accepts or rejects the connection. For very busy systems, use a value in the range of 45 to 60 seconds. Otherwise use a value of 30 seconds.

ADDRESSAREABROADCASTBUFFERSCIRCUITSCOST
DECLARED OBJECTSHOPSLINKSPATH SPLITSVISITS
ADDRESS
Defines the largest node address and, consequently, the greatest number of nodes that can be addressed by the local node. Use as small a number as possible. If you receive an "INVALID VALUE" error, you probably have not allocated enough nonpaged pool space. You must lower the MAXIMUM ADDRESS value or increase the VAX/VMS NPAGEDYN value. See Chapter 5 of the Guide to Networking on VAX/VMS for some guidelines on NPAGEDYN.

CIRCUITS
Defines the maximum number of transport circuits that the local node can use. Number must be in the range 1 to 32. If you receive an "INVALID VALUE" error, you probably have not allocated enough Non Paged Pool space. You must lower the MAXIMUM CIRCUITS value or increase the VAX/VMS NPAGEDYN value. See Chapter 5 of the Guide to Networking on VAX/VMS for some guidelines on NPAGEDYN.
COST
Specifies the maximum total path cost allowed from the local node to any node. The path cost is the sum of the line costs along a path between two nodes. Use as small a number as possible in the range of 1 to 1023.
DECLARED OBJECTS
Specifies the maximum number of objects that processes may declare. Use a number in the range of 8 to 16383. The default is 31.
HOPS
Specifies the maximum routing hops from the local node to any other reachable node. A hop is the logical distance over a line between two adjacent nodes. Use as small a number as possible in the range of 1 to 31, and be sure that this value is less than or equal to the MAXIMUM VISITS parameter. If you receive an "INVALID VALUE" error, you probably have not allocated enough Non Paged Pool space. You must lower the MAXIMUM HOPS value or increase the VAX/VMS NPAGEDYN value. Refer to Chapter 5 of the Guide to Networking on VAX/VMS for some guidelines on NPAGEDYN.

on any outgoing logical links.
ENABLED: Specifies that proxy invocation is requested on
all outgoing logical links.
TIMER
Specifies a time out value for the duration between the time a connection is requested and the time that connection is acknowledged by the destination node. It is recommended that you use a value in the range of 30 to 60 seconds.
PATH SPLIT POLICY
Specifies the policy for equal cost load splitting of network traffic.
There are two values for PATH SPLIT POLICY
INTERIM: Specifies that all traffic will be split over all
equal cost paths while forcing individual network
sessions over the same paths in order to guarantee
that packets will be received by the destination
node in the correct order. The INTERIM value should
be set if some of the nodes in the network do not
support out-of-order packet caching. (VMS version
4.5 and earlier VMS releases do not support
out-of-order caching).
NORMAL: Specifies that all traffic will be split equally
over all equal cost paths to a destination node.
All nodes must support out-of-order packet caching
(Supported by VMS Version 4.6 or later), otherwise,
network performance may suffer. This is the default
value for PATH SPLIT POLICY.
PIPELINE QUOTA
Specifies the maximum number of bytes of nonpaged pool that DECnet will use for transmission over logical links. Use this parameter for multibuffering at the NSP level.
PRIVILEGED
Specifies privileged inbound access control information for the node. This parameter is not needed unless the PRIVILEGES parameter is used explicitly in the object database. All underscores found in parameters must be replaced with spaces when parameters are used in NCP commands.

Specifies the maximum duration before a routing update is forced. The routing update produces a routing configuration message for each adjacent node. You can use a number in the range of 1 to 65535. If you don't set this parameter, NETACP will supply a default value. It is recommended that you allow NETACP to supply the default.
SEGMENT BUFFER SIZE
Specifies in bytes the maximum number of transmit buffers, thereby controlling the maximum size NSP message segment that can be transmitted. (This value is the maximum size message the End Communication layer can transmit; it does not include Routing layer or Data Link layer overhead.) Use a value in the range 1 to 65,535. The default value is equal to the value of the BUFFER SIZE if specified; otherwise the default is 576.
STATE
Specifies the operational state of the local node. There are
four possible states:
OFF Allows no new logical links,
terminates existing links,
and stops route-through
traffic
ON Allows logical links
RESTRICTED Allows no new inbound links
from other nodes
SHUT Allows no new logical links,
does not destroy existing
links, and goes to the OFF
state when all logical links
are gone
SUBADDRESS range
Applies only to VAX-11 PSI. Specifies a range of local DTE subaddresses that the Routing Layer will accept as X25 DLM calls. VAX-11 PSI will route all incoming X25 calls within the specified subaddress range to the Routing Layer to be handled as DLM calls.
TYPE
Indicates the type of the executor node. Possible node types are
ROUTING IV
NONROUTING IV
AREA
The default depends upon the DECnet-VAX license installed. If the
full function kit is installed, the default is ROUTING IV; if the end
node kit is installed, the default (and only possible value) is
NONROUTING IV.
A routing node has full routing capability. A nonrouting node (or end
node) can deliver packets to or receive them from any node, but
cannot route packets from other source nodes through to destination
nodes.
An area node is a level 2 router that can route packets between areas.

Examples
NCP>SET NODE 5.14 NAME DENVER
This command sets the node name of node 5.14 to DENVER.
NCP>SET NODE 2.11 -
_ NONPRIVILEGED -
_ USER NETNONPRIV -
_ PASSWORD NONPRIV -
_ PRIVILEGED -
_ USER NETPRIV -
_ PASSWORD PRIV
This command establishes default privileged and nonprivileged
access control information for node 2.11.
NCP>SET NODE 14 ADDRESS 2
This command associates the information for node 1.14 with a
new node whose address is 1.2. This example assumes that the
executor is in area 1.
NCP>SET NODE LARK HARDWARE ADDRESS AA-00-03-00-00-00
This command associates with the node LARK the Ethernet
hardware address originally assigned to the DEUNA controller
at node LARK. This information in the volatile database can
be used during downline loading of target node LARK over an
Ethernet circuit.
OBJECT
Use the SET OBJECT command to create or modify object parameters in the
volatile database on the local node. Use the DEFINE OBJECT command to
create or modify object parameters in the permanent database on the
local node.
SET OBJECT object-name (parameters ...)
All underscores found in parameters must be replaced with spaces
when parameters are used in NCP commands.
Additional information available:
OBJECT object-nameACCOUNT accountFILE file-specNUMBER number
OUTGOING CONNECT PRIVILEGES privilege-listPASSWORD passwordPRIVILEGES privilege-list
PROXY optionUSER user-idExamples
KNOWN OBJECTS
Applies only to VAX PSI. Indicates that the specified parameters are applicable to all known objects.
OBJECT object-name
Identifies the object for which specified parameters are to be created or modified in the database. For VAX PSI, specify the object name using an id-string.
ALL
The SET OBJECT ALL command to updates the volatile database on the local node with all the object parameters stored for a particular object in the permanent database on the local node.
ACCOUNT account
Identifies the default user's account for access control on inbound connects to the object when no access control is specified by the remote node. For VAX PSI, identifies the user account for use by incoming X25 calls to the object; if not specified, no account is used.
ALIAS
Additional information available:
INCOMING optionOUTGOING option
INCOMING option
Specifies how a particular object responds to incoming connect
requests directed to the alias node address. The alias node address
is established using the SET EXECUTOR command. There are two options
for ALIAS INCOMING:
ENABLED Allows a specified object to receive incoming connect
requests that have been directed to the alias node
address. An object such as PHONE which uses a protocol
that depends on multiple links should not be enabled
for ALIAS INCOMING. By default, if an alias node
identifier has been specified, ALIAS INCOMING is
enabled for all objects except for PHONE.
DISABLED Does not allow a specified object to receive incoming
connect requests that have been directed to the alias
node address. An object whose resources are not
accessible clusterwide should not have ALIAS INCOMING
disabled. If an attempt is made to connect to an
object that does not have ALIAS INCOMING enabled, the
status message NO SUCH OBJECT is returned.
OUTGOING option
Specifies whether a particular object uses the alias node identifier
specified in the SET EXECUTOR command in its outgoing connect requests
and other protocols. Specify either of the following two options:
ENABLED Allows a specified object to use the alias node
address in its outgoing connect requests. An object
such as PHONE which uses a protocol that depends on
multiple links should not have the ALIAS OUTGOING
parameter enabled. By default, only the object MAIL
has ALIAS OUTGOING enabled.
DISABLED Does not allow a specified object to use the alias
node address in its outgoing connect requests.
FILE file-spec
Specifies the command file containing the command procedure used to
start the indicated object. If not specified, the default is
SYS$SYSTEM:object-name.COM
For VAX PSI, this parameter specifies the command file containing the
command procedure used to activate a user program or task. When you
specify an object for the first time, this parameter is mandatory.
NUMBER number
Specifies the object number. Use a number in the range of 0 to 255, except for those reserved. When you specify an object for the first time, this parameter is mandatory. For VAX PSI, specify this parameter as 0.
OUTGOING CONNECT PRIVILEGES privilege-list
Specifies the privileges that a user must possess in order to make outbound connections to the object. Refer to the VAX/VMS System Manager's Reference Manual for a complete list of privileges and their meanings. Does not apply to VAX PSI.
PASSWORD password
Identifies the default user's password for access control on inbound connects to the object when no access control is specified by the remote node. This password must match the password established for the account. For VAX PSI, this parameter is mandatory. It identifies the user's password for use by incoming X25 calls to the object.
PRIVILEGES privilege-list
Specifies those privileges normally required by the object. A user with those privileges may be supplied with default outbound privileged access control information when connecting to the object. Refer to the VAX/VMS System Manager's Reference Manual for a complete list of privileges and their meanings. Does not apply to VAX PSI.
PROXY option
Assigns the proxy login access defaults to individual objects. Specify
one of the following four options:
INCOMING Allows proxy login to the object.
OUTGOING Allows the object to initiate proxy login.
BOTH Allows both incoming and outgoing proxy login access.
This is the default option.
NONE Does not allow incoming or outgoing proxy login
access.
USER user-id
Identifies the default user's identification for access control on inbound connects to the object when no access control is specified by the remote node. For VAX PSI, this parameter specifies the user identification for use by incoming X25 calls to the object; this parameter is mandatory when you specify an object for the first time.
Examples
NCP>SET OBJECT NML FILE NML NUMBER 19
This command an object number, 19, for the NML object.
NCP>SET OBJECT NML-
_ PRIVILEGES OPER DIAGNOSE -
_ USER NET_NONPRIV -
_ PASSWORD NET_NONPRIV
This command establishes default access control information
for the NML object and sets those privileges required to
connect to this object.
