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 sharinga 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
802.3 committee 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.
