link-local address
link-local address . An address having link-only scope that can be used to reach
neighboring nodes attached to the same link. All interfaces have a link-local unicast
address.
link MTU. The maximum transmission unit, for example, maximum packet size in octets,
that can be conveyed over a link.
LLC (Logical Link Control). See Logical Link Control (LLC).
LNP. See logical network partitioning.
local area network (LAN). A network that is located in a small geographical area and
whose communications technology provides a high-bandwidth, low-cost medium to
which low-cost nodes can be connected. One or more LANs can be connected to the
system such that the LAN users can access the system as if their workstations were
connected directly to it.
logical interface (LIF). The interface that allows an application or another process to
communicate with data communications hardware.
Logical Link Control (LLC). An IEEE 802.2 standard for the Data Link Layer of the OSI
Reference Model that defines both connection-oriented and connectionless standards
over LAN networks.
logical network partitioning. A NonStop TCP/IPv6 feature that allows you to divide the
system into separately addressed IP subnetworks whereby applications have access
only to a defined set of network interfaces (IP addresses).
MAC address (Media Access Control Address). A MAC address is a value in the Medium
Access Control sublayer of the IEEE/ISO/ANSI LAN architecture, that uniquely
identifies an individual station that implements a single point of physical attachment to
a LAN.
management applications. In DSM, an application process that opens a management or
subsystem process to control a subsystem. This process can issue SPI commands to
subsystems and retrieve EMS event messages to assist in the management of a
computer system or a network of systems. A management application is a requester to
the subsystems to which it sends commands; the subsystems are servers to the
management application.
management process. In DSM, an HP process through which an application issues
commands to a subsystem. A management process can be part of a subsystem, or it
can be associated with more than one subsystem; in the latter case, the management
process is logically part of each of the subsystems. SCP is the management process
for all HP data communications subsystems that support DSM. See also subsystem.
manager process. In DSM, an HP subsystem process with which the SCP management
process communicates to control a particular data communications subsystem.
