ServerNet wide area network (SWAN) 2
concentrator.
ServerNet wide area network (SWAN) 2 concentrator. An HP data communications
peripheral that provides connectivity to an HP NonStop S-series server. The SWAN 2
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces. The SWAN 2 concentrator is
the next-generation SWAN concentrator and has 12 WAN ports.
Simple Network Management Protocol (SNMP). An asynchronous request-response
protocol used for network management. SNMP originated as a means for managing
Transmission Control Protocol/Internet Protocol (TCP/IP) and Ethernet networks. OSM
and TSM packages can include an SNMP-compliant interface for communication
between the system console and NonStop S-series server.
SNMP. See Simple Network Management Protocol (SNMP).
SPI. See Subsystem Programmatic Interface (SPI).
subnet. See subnetwork.
subnetwork. A physical network within an Internet protocol (IP) network. Each IP network
can be divided into a number of subnetworks. Within a given network, each
subnetwork is treated as a separate network. Outside the network, the subnetworks
appear as part of a single network. The terms subnetwork and subnet are used
interchangeably.
Subsystem Control Facility (SCF). An interactive interface for configuring, controlling, and
collecting information from a subsystem and its objects. SCF enables you to configure
and reconfigure devices, processes, and some system variables while your HP
NonStop S-series server is online.
Subsystem Programmatic Interface (SPI). A set of procedures and associated definition
files and a standard message protocol used to define common message-based
interfaces for communication between management applications and subsystems. It
includes procedures to build and decode specially formatted messages; definition files
in Transaction Application Language (TAL), COBOL85, and HP Tandem Advanced
Command Language (TACL) for inclusion in programs, macros, and routines using the
interface procedures; and definition files in Data Definition Language (DDL) for
programmers writing their own subsystems.
SWAN concentrator. See ServerNet wide area network (SWAN) concentrator.
SWAN 2 concentrator. See ServerNet wide area network (SWAN) 2 concentrator.
TFTP. See Trivial File Transfer Protocol (TFTP).
Transmission Control Protocol/Internet Protocol (TCP/IP). A set of layered
communication protocols for connecting workstations and larger systems in both local
area networks (LANs) and wide area networks (WANs).
