ServerNet LAN Systems Access (SLSA) subsystem
processor multifunction (PMF) customer-replaceable unit (CRU), an I/O multifunction
(IOMF) CRU, or a ServerNet adapter.
ServerNet LAN Systems Access (SLSA) subsystem. A subsystem of the NonStop
operating system. The SLSA subsystem enables the protocol I/O processes (IOPs)
and drivers to access the ServerNet adapters.
ServerNet wide area network (SWAN) concentrator. An HP data communications
peripheral that provides connectivity to a NonStop S-series server. The SWAN
concentrator supports both synchronous and asynchronous data over RS-232,
RS-449, X.21, and V.35 electrical and physical interfaces.
service. A set of primitives (operations) that a layer provides to the layer above it. The
service defines what operations the layer can perform on behalf of its users, but not
how these operations are implemented. A service relates to an interface between two
layers: the lower layer is the service provider, and the upper layer is the service user.
Compare protocol.
session. For a management application, the period during which an application can issue
commands to a subsystem.
shadow route. For multiple routes to the same destination (all the routes in addition to the
primary route) the route visible to Radix Routing topology, are called
shadow/secondary routes. Also called secondary route on page -17.
Simple Mail Transfer Protocol (SMTP). The Internet standard protocol for transferring
electronic mail messages from one machine to another. SMTP specifies how two mail
systems interact, and specifies the format of control messages the two mail systems
exchange to transfer mail.
simple token. In DSM programmatic interfaces, a token consisting of a token code and a
value that is either a single elementary field, such as an integer or a character string, or
a fixed (nonextensible) structure. Compare extensible structured token.
site-local address. An address having scope that is limited to the local site.
SLSA Subsystem. See ServerNet wide area network (SWAN) concentrator
SMTP. See Simple Mail Transfer Protocol (SMTP).
SNAP. See Subnetwork Access Protocol (SNAP).
solicited-node multicast address. A multicast address to which neighbor solicitation
messages are sent.
SPI. See Subsystem Programmatic Interface (SPI).
SPI buffer. The buffer that contains an SPI message. See also SPI message.
