Glossary

802.1p: IEEE Standard supplement, now incorporated in IEEE 802.1D. Defines 8 priority levels for traffic classification at the data link level and suggests how they might be used.

802.1Q: IEEE Standard that specifies the architecture for VLAN tagging, association, and VLAN-capable bridges.

100Base-T:A 100 Mbit/s communication method specified in the IEEE 802.3u-1995 standard. The official name for Fast Ethernet.

Alias: Name of the interface that corresponds to a given Internet address on a system.

Canonical format indicator: The CFI bit indicates that all MAC addresses present in the MAC data field are in canonical format.HP-UX always transmits a CFI of 0.

Card Instance Number: A number that uniquely identifies a device within a class. A class of devices is a logical grouping of similar devices.

CoS: Class of Service. The ability to provide different levels of service to various traffic flows. A flow may be determined explicitly via tags or implicitly from the frame contents (such as the IP address or ToS field). Class of Service (CoS) network management is when similar types of traffic (for example, voice, video, or data) are grouped together and assigned a priority. Unlike Quality of Service (QoS) traffic management, CoS does not guarantee a level of service in terms of bandwidth and delivery time.

Destination Address: A field in the message packet format identifying the end node(s) to which the packet is being sent.

Ethernet: A 10 Mbit/s LAN, developed by Digital Equipment Corporation, Intel, and Xerox Corporation, upon which the IEEE 802.3 network is based.

Fast Ethernet: A commonly used name applied to 100Base-T.

HSC: High speed connect bus.

Hardware Path: An identifier assigned by the system according to the physical location (slot) of a card in the hardware backplane.

Hostname: Name of system on the network.

Hub: A network interconnection device that allows multiple devices to share a single logical link segment. Hubs are generally either 10 Mbit/s or 100 Mbit/s devices.

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. For example, the 800 committees study local area network technologies. The 802.3 committee produced the standard for a CSMA/CD local area network, which has been adopted by ANSI.

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.
