Glossary
Internet Address: The network address of a computer node. This address identifies both which network the host is on and which host it is. Refer to 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.
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.
Mbps: Megabits per second
MBps: Megabytes per second
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.
Network Management Identifier (NMID): A unique ID assigned by the system for the network management of each network interface.
NMID: See Network Management Identifier
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 (OLA/R): The ability of a PCI I/O card to be added or replaced without the need to shut down or reboot the system. For instructions on how to perform OLA/R, refer to Configuring
P
PCI: Peripheral Component Interconnect.
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, distinct from NMID.
PMTU: Path MTU
PPA: See Physical Point of Attachment
Protocol: A specification for coding messages exchanged between two communications processes.
R
S
Subnetwork: Small discrete physical networks connected via gateways which share the same network address space. Refer to Installing and Administering LAN/9000 Software for detailed information about subnetworks and subnet addressing.
Subnet mask: A
