EMC DS-8B manual FPortt, FLPort

Glossary

FL_Port Fabric Loop Port. A port that can transmit under both fabric protocol and loop protocol. Can be used to connect NL_Ports to a switch. See also F_Port, Fx_Port.

FLOGI Fabric Login. Process by which a node makes a logical connection to fabric. Used by ports to determine if fabric is present, and if so to exchange service parameters with the fabric. See also PLOGI.

Frame Fibre channel structure used to transmit data. Consists of start-of-frame delimiter, header, any optional headers, data payload, cyclic redundancy check (CRC), and end-of-frame delimiter. There are two types: data frames and link control frames. Similar to the networking concept “packet”. See also Sequence, Data word.

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, Name Server is a fibre channel service. See also FSP.

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

FSPF Fabric Shortest Path First. DS-16B and DS-8B routing protocol for fibre channel switches.

Full-duplexMode of communication that allows a port to simultaneously transmit and receive frames. See also Half-duplex.

Fx_Port Fabric port that can operate either as F_Port or FL_Port. See also

F_Portt, FL_Port.

G

G_Port Generic Port. Port that can operate either as E_Port or F_Port. Ports are defined as G_Ports when disconnected or have not assumed specific function within fabric.

Gateway IP address assignment that provides translation for incompatible networks. For example, ATM gateway can connect a fibre channel link to an ATM connection.

GBIC Gigabit Interface Converter. Removable serial transceiver module that allows gigabit physical-layer transport for fibre channel.
