IXF
IXF.  See Information Xchange Facility (IXF). 
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). 
LAN Print Spooler for NetWare. A HP print process that delivers print spooler jobs to 
NetWare print queues.
LIF. See logical interface (LIF). 
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 (LANs), 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. LLC (Logical Link Control). 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.
local area network.  See LAN.
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.
MAC address.  (Media Access Control Address) A 12-digit hexadecimal number. Each 
TLAM controller is assigned a unique MAC address, which is burned into its PROM as 
part of the manufacturing process. HP, like other manufacturers of IEEE 802.3 
controllers, is licensed to use a dedicated range of MAC addresses. That way, each 
controller is guaranteed a unique address. For G-series RVUs: 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 process.  In DSM, a 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.
