Fibre Channel A protocol service that supports communication between Fibre
Transport Channel service providers. See also FSP.
Fill Word An IDLE or ARB ordered set that is transmitted during breaks between data frames to keep the Fibre Channel link active.
Firmware The basic operating system provided with the hardware.
FL_Port Fabric Loop Port; a port that is able to transmit under fabric protocol and also has arbitrated loop capabilities. Can be used to connect an NL_Port to a switch. See also F_Port and Fx_Port.
FLOGI Fabric Login; the process by which an N_Port determines whether a fabric is present, and if so, exchanges service parameters with it. See also PLOGI.
Frame The Fibre Channel structure used to transmit data between ports. Consists of a start of frame delimiter, header, any optional headers, the data payload, a cyclic redundancy check (CRC), and an end of frame delimiter. There are two types of frames: Link control frames (transmission acknowledgements, etc.) and data frames.
