Glossary

This glossary defines terms used in this guide or related to this product. It is not a comprehensive glossary of computer terms.

AL_PA EE_Credit	Arbitrated loop physical address. A unique 8-bit value assigned during loop
	initialization to a port in an arbitrated loop. See also non-participating mode.
alias server	A fabric software facility that supports multicast group management.
API	Application programming interface. A defined protocol that allows applications to
	interface with a set of services.
arbitrated loop	A shared 100 Mb/s Fibre Channel transport structured as a loop. Can support up to
	126 devices and one fabric attachment. See also public device, public loop.
AW_TOV	Arbitration wait time-out value. The minimum time an arbitrating L_Port waits for a
	response before beginning loop initialization.

backup FCS switch Backup fabric configuration server switch. The switch or switches assigned as backup in case the primary FCS switch fails.

bandwidth	The total transmission capacity of a cable, link, or system. Usually measured in bits per
	second (b/s). May also refer to the range of transmission frequencies available to a
	link or system.
broadcast	The transmission of data from a single source to all devices in the fabric, regardless of
	zoning.

buffer-to-buffer flow control

CLI

Management of the frame transmission rate in either a point-to-point topology or an arbitrated loop. See also arbitrated loop, point-to-point, topology.

Command line interface. Interface that depends entirely on the use of commands, such as through telnet or SNMP, and does not involve a GUI.

compact flash	Flash (temporary) memory that is used in a manner similar to hard disk storage. It is
	connected to a bridging component that connects to the PCI bus of the processor. Not
	visible within the processor’s memory space.
configuration	The way a system is set up. May refer to hardware or software:
	• Hardware: The number, type, and arrangement of components that make up a
	system or network.
	• Software: The set of parameters that guide switch operation. May include general
	system parameters, IP address information, domain ID, and other information.
	Modifiable by any login with administrative privileges. May also refer to a set of
	zones.
CRC	Cyclic redundancy check. A check for transmission errors that is included in every data
	frame.
data word	A type of transmission word that occurs within frames. The frame header, data field,
	and CRC all consist of data words.
