EE_Credit
AL_PA 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_TO V 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
Management of the frame transmission rate in either a point-to-point topology or an

CLI 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

configuration The way a system is set up. M ay refer to hardware or software:
•Hardware: The number, type, and arrangement of components that make up a
system or net work.
•Software: The set of parameters that guide switch operation. May include general

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,
