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 HP-UX For Peripherals.

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

RJ-45:The name for the connector type used with UTP cabling.

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 32-bit mask which, when AND'd with an internet address, determines a subnetwork address. When the internet address is AND'd with the subnet mask, the ones in the host portion of the subnet mask will “overwrite” the corresponding bits of the host portion of the internet address, resulting
