ISO
ISO. See International Organization for Standardization (ISO).
ITU-T. See International Telecommunications Union Telecommunications (ITU-T).
LAN (local area network). Any physical network technology that operates at high speed
(usually tens of megabits per second through several gigabits per second) over short
distances (up to a few thousand meters).
LANMAN. See LAN manager (LANMAN) process.
LAN. See local area network (LAN).
LAN manager (LANMAN) process. The process provided as part of the ServerNet local
area network (LAN) systems access (SLSA) subsystem that starts and manages the
SLSA subsystem objects and the LAN monitor (LANMON) process and assigns
ownership of Ethernet adapters to the LANMON processes in the system. Subsystem
Control Facility (SCF) commands are directed to the LANMON processes for
configuring and managing the SLSA subsystem and the Ethernet adapters.
LANMON. See LAN monitor (LANMON) process.
LAN monitor (LANMON) process. The process provided as part of the ServerNet local
area network (LAN) systems access (SLSA) subsystem that has ownership of the
Ethernet adapters controlled by the SLSA subsystem.
LAPB (Link Access Protocol —Balanced). ITU-T standards that define in the Data Link
Layer the requirements for X.25 connections over wide area networks (WANs).
Level 2. A reference to LINK LEVEL communication (for example, frame formats) or link-
level connections derived from the ISO 7-layer reference model. For long-haul
networks, level 2 refers to the communication between a host computer and a network
packet switch (for example, HDLC/LAPB). For local area networks, level 2 refers to
physical packet transmission. Thus, a level 2 address is a physical hardware address.
Level 3. A reference to NETWORK-level communication derived from the ISO 7-layer
reference model. For the Internet, level 3 refers to the IP and IP datagram formats.
Thus, a level 3 address is an Internet address.
LIF. See logical interface (LIF).
link. a communication facility or medium over which nodes can communicate at the link
layer, i.e. the layer immediately below IP. Examples are Ethernet and internet (or
higher) layer tunnels, such as tunnels over IPv4 or IPv6 itself.
link-layer address. A link-layer identifier for an interface. Examples include IEEE 802
addresses for Ethernet links and E.164 addresses for ISDN links.
