Glossary
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.
FLOGI
Fabric Login; the process by which an N_Port determines whether a fabric is present, and if
so, exchanges service parameters with it.
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.
FS_ACC
Fibre Channel Services Accept. The information unit used to indicate acceptance of a
request for a Fibre Channel service.
FSP
Fibre Channel Service Protocol; the common protocol for all fabric services, transparent to
the fabric type or topology.
FSPF
Fabric Shortest Path First; the routing protocol for Fibre Channel switches.
Full Fabric
The licensing that allows multiple E_Ports on a switch, making it possible to create
multiple ISL links.
Full-duplex
A mode of communication that allows the same port to simultaneously transmit and receive
frames.
Fx_Port
A fabric port that can operate as either an F_Port or 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.
Gateway
A device such as a switch that connects different subnets together. A switch can be used as
a gateway from the Ethernet to the Fibre Channel. Set the gateway address on one switch to
the Fibre Channel IP address of another switch to enable the other switch to forward IP
traffic to the Ethernet port on the second switch.
Gbps
Gigabits per second (1,062,500,000 bits/second).
