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
arbitrated loop , point-to-point , topology .
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
