IEEE 802.3u-1995 network: A 10- or 100- Mbit/s
LAN, specified in the IEEE 802.3u-1995 Standard
for LANs. It uses the Carrier Sense Multiple
Access/Collision Detection (CSMA/CD) network
access method to give every node equal access to the
network.
Internet Address: The network address of a
computer node. This address identifies both which
network the host is on and which host it is. See the
Installing and Administering LAN/9000 Software
manual for detailed information about network
addressing.
IP Address: See Internet Address.
L
LAN: See Local Area Network.
LAN Provider: A software module that you can use
to find and collect information about the Ethernet
links on a system. It is based on the CIM (Common
Information Model) standard from the distributed
management task force (DMTF).
Local Area Network (LAN): A data
communications system that allows a number of
independent devices to communicate with each
other.
Local Network: The network to which a node is
directly attached.
M
Major Number: Unique value that identifies an
individual hardware device.
Maximum Transmission Unit (MTU): Largest
amount of data that can be transmitted through that
interface. This value does not include the LLC or
MAC headers.
Mbit/s: Megabits per second
Mbyte/s: Megabytes per second
MIB: Management information base. An SNMP
data structure that specifies what data can be
obtained from or controlled in a device.
MTU: See Maximum Transmission Unit
N
Network Interface: A communication path
through which messages can be sent and received. A
hardware network interface has a hardware device
associated with it, such as a LAN or FDDI card. A
software network interface does not include a
hardware device, for example, the loopback
interface. For every IP address instance, there must
be one network interface configured.
Node: Any point in a network where services are
provided or communications channels are
interconnected. A node could be a workstation or a
server processor.
O
Online Addition/Replacement (OL*): The ability
of a PCI-X I/O card to be added or replaced without
the need to shut down or reboot the system. For
instructions on how to perform OL*, see Configuring
HP-UX For Peripherals.
P
PCI-X: Peripheral Component
Interconnect-Extended) An enhanced version of PCI
bus technology originally developed by IBM, HP and
Compaq. PCI-X is a superset of PCI; PCI-X is
backward compatible with existing PCI cards. PCI-X
cards can run in PCI slots though at the slower PCI
speed. 64-bit PCI-X slots are longer than 32-bit
PCI-X slots.
Packet: A sequence of binary digits that is
transmitted as a unit in a computer network. A
packet usually contains control information plus
data.
Physical Point of Attachment: A unique number
assigned to each network interface.
PMTU: Path MTU
PPA: See Physical Point of Attachment
Protocol: A specification for coding messages
exchanged between two communications processes.
