Numerics
1000Base-SX:A specific implementation of 1000Mbps operating over two multimode fiber cables, as specified in Standard IEEE 802.3z/D.50-1998.
1000Base-T:A specific implementation of 1000 Mbps operating over four-pair Cat-5 or Cat-5e UTP cables, as specified in IEEE 802.3ab standards.
A
Alias: Name of the interface that corresponds to a given Internet address on a system.
Autonegotiation: A mechanism defined in IEEE 802.3u-1995 whereby devices sharing a link segment can exchange data and automatically configure themselves to operate at the highest capability mode shared between them. This is also used for link configuration per IEEE 802.3z and IEEE 802.3ab standards of duplex and flow control configuration between two 1000Base-SX/T links.
C
Card Instance Number: A number that uniquely identifies a device within a class. A class of devices is a logical grouping of similar devices.
D
Destination Address: A field in the message packet format identifying the end node(s) to which the packet is being sent.
DHCP: Dynamic Host Configuration Protocol
DLPI: Data Link Provider Interface. An industry-standard definition for message communications to STREAMS-based network interface drivers.
E
Ethernet: A 10 Mbps LAN, developed by Digital Equipment Corporation, Intel, and Xerox Corporation, upon which the IEEE 802.3 network is based.
F
Fast Ethernet: A commonly used name applied to 100Base-T.
Full-Duplex Mode: A mode of media utilization whereby data can flow in both directions simultaneously across the multiple wire pairs of a physical link. While full-duplex operation is not defined per se in the IEEE 802.3u-1995 specification, the specification does define a mechanism for this mode to be autonegotiated between devices on each end of a link. Full-duplex mode is typically found on switches.
H
HSC: High-speed connect bus.
Half-Duplex Mode: The media utilization mode of IEEE 802.3u-1995 networks whereby data can flow in only one direction at a time across the multiple wire pairs of a physical link.
Hardware Path: An identifier assigned by the system according to the physical location (slot) of the card in the hardware backplane. On HP servers, the I/O subsystem identifies each LAN card by its hardware path.
Hostname: Name of system on the network.
Hub: A network interconnection device that allows multiple devices to share a single logical link segment.
I
IEEE: The Institute of Electrical and Electronics Engineers. A national association, whose activities include publishing standards applicable to various electronic technologies. The IEEE technical committees are numbered and grouped by area. The
802.3committee produced the standard for LAN networks.
IEEE 802.3u-1995 network: A 10 or 100 Mbps LAN, specified in the IEEE 802.3u-1995 Standard for Local Area Networks. It uses the Carrier Sense Multiple Access/Collision Detection (CSMA/CD) network access method to give every node equal access to the network.
