nonsensitive command
(X25AM), NonStop TCP/IP, and Tandem LAN Access Method (TLAM) subsystem
[replaced by the Port Access Method (PAM) subsystem for G-series releases].
nonsensitive command. A Distributed Systems Management (DSM)
command that can be
issued by any user or program allowed access to the target subsystem—that is, a
command on which the subsystem imposes no further security restrictions. For Compaq
data communications subsystems, the nonsensitive commands are all those that cannot
change the state or configuration of objects (usually information commands). Compare
sensitive command
.
NonStop TCP/IP. A communications subsystem that provides access to a network, allowing
you to use the file transfer protocol (FTP) to transfer files to your Compaq system and
run Web-based servers through facilities such as Simple Mail Transfer Protocol (SMTP).
NonStop TCP/IP also provides multicast support, which enables Himalaya S-series
servers to initiate and receive messages intended for multiple Internet Protocol (IP)
addresses associated with Internet subscriptions. See also Transmission Control
Protocol/Internet Protocol (TCP/IP).
NSAP. See network service access point (NSAP)
.
NSAP address. See network service access point (NSAP) address
.
object-name template. In Distributed Systems Management (DSM)
, a name that stands for
more than one object. Such a name includes one or more wildcard characters, such as *
and ?.
Open Systems Interconnection (OSI). A set of standards used for the interconnection of
heterogeneous computer systems, thus providing universal connectivity.
Open Systems Interconnection (OSI) address. The address of an object on the network,
which includes the network service access point (NSAP)
, transport selector (TSEL),
session selector (SSEL), and presentation selector (PSEL). See also Open Systems
Interconnection (OSI).
Open Systems Interconnection (OSI) manager process. A process in the Open Systems
Interconnection (OSI) subsystem that performs subsystem management functions,
including management of the Management Information Base (MIB). There is one OSI
manager process per OSI subsystem. See also Open Systems Interconnection (OSI)
.
Open Systems Interconnection (OSI) Reference Model. A communications architecture,
adopted by the International Standards Organization (ISO) in 1984, that includes seven
layers that define the functions involved in communications between two systems, the
services required to perform these functions, and the protocols associated with these
services. See also Open Systems Interconnection (OSI)
.
Open Systems Interconnection (OSI) subsystem. One OSI manager process controls one or
more TAPS and TSP processes. The OSI manager processes communicates with NSP
processes but do not control them. The OSI manager, TAPS, TSP, NSP processes can be
on the same or different nodes within the same Expand network. See also Open Systems
Interconnection (OSI) and Open Systems Interconnection (OSI) manager process.
