AL_PA Arbitrated loop physical address. A unique 8-bit value assigned during loop
initialization to a por t in an arbitrated loop. See also ???.
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. Supports up
to 126 devices and one fabric attachment. See also ???, ???.
AW_TOV Arbitration wait time-out value. The minimum time an a rbitrating 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 arbitrated loop. See also ???, ???, ???.
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 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 arra n gem ent of components that make up
asystemornetwork.
• 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.
defined zone
configuration
Thesetofallzoneobjectsdefi ned in the fabric. May include multiple zone
configurations. See also ???, ???.
