Fabric Watch User’s Guide

Glossary-5

FC-SW-2

The second generation of the Fibre Channel Switch Fabric standard defined by 
ANSI. Specifies tools and algorithms for the interconnection and initialization of 
fibre channel switches in order to create a multi-switch fibre channel fabric. 

Fibre Channel 
Transport

A protocol service that supports communication between fibre 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_PortFx_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.

FRU

Field-replaceable Unit; a component that can be replaced on site.

FS

Fibre Channel Service; a service that is defined by fibre channel standards and 
exists at a well-known address. For example, the Simple Name Server is a fibre 
channel service. See also FSP.

FSP

Fibre Channel Service Protocol; the common protocol for all fabric services, 
transparent to the fabric type or topology. See also FS.

FSPF

Fabric Shortest Path First; Brocade’s routing protocol for fibre channel switches.

Full-duplex

A mode of communication that allows the same port to simultaneously transmit 
and receive frames. See also Half-duplex.

Fx_Port

A fabric port that can operate as either an F_Port or FL_Port. See also F_Port
FL_Port.

G_Port

Generic Port; a port that can operate as either an E_Port or F_Port. A port is 
defined as a G_Port when it is not yet connected or has not yet assumed a specific 
function in the fabric.

GBIC

Gigabit Interface Converter; a removable serial transceiver module that allows 
gigabaud physical-level transport for fibre channel and gigabit ethernet.

Gbps

Gigabits per second (1,062,500,000 bits/second).

GBps

GigaBytes per second (1,062,500,000 bytes/second).

Half-duplex

A mode of communication that allows a port to either transmit or receive frames 
at any time, but not simultaneously (with the exception of link control frames, 
which can be transmitted at any time). See also Full-duplex.

Hard Address

The AL_PA that an NL_Port attempts to acquire during loop initialization.

HBA

Host Bus Adapter; the interface card between a server or workstation bus and the 
fibre channel network.
